The QNix® 7500 coating thickness measuring gauge is part

of the product line of non-destructive measurement gauges.

Designed for the future, this modular system gauge is cha-

racterized by a wide application range and a robust build,

already well known from our other gauges. It is possible for

example to use the QNix® 7500 with an integrated probe as

a one-hand operated gauge, or by using a connecting ca-

ble, as a gauge with an external probe. Using the respective

probe, the gauge will measure coatings on steel and iron or

coatings on a non-magnetic, metallic substrate such as

aluminium.

Please read these instructions carefully before operating

the gauge for the first time. It will help you to make use of all

advantages and conveniences the QNix® 7500 has to offer.

Would you like to know more about the other coating thick-

ness gauges of our product line? Or do you have any ques-

tions concerning coating thickness measuring? Please do

not hesitate to contact us. Our specialists with their long-

standing experience will be glad to assist you.

The QNix® 7500 coating thickness measuring gauge is a

combination gauge with a wide range of applications. Op-

tionally, it is available with memory and statistical functions

(QNix® 7500 M).

The basic gauge can be combined with an integrated Fe-,

NFe- or dual-probe. If the gauge shall be used with an ex-

ternal probe, just pull the probe out of the gauge and con-

nect the probe with the optionally available adapter cable.

The Fe-probe measures all non-magnetic coatings such as

lacquer, powder coatings, plastic, enamel, chromium, cop-

per, zinc, etc. on steel or iron.

The NFe-probe measures all insulating coatings such as

lacquer, plastic, enamel, etc. on non-magnetic substrates

such as aluminium, copper, brass or stainless steel.

With the integrated interface readings can be transferred

online to a computer (serial-port or USB-port).

The QNix® 7500 M coating thickness measuring gauge can

be supplied with memory to store readings and even subdi-

vide them into blocks. Up to 3900 readings can be stored.

As a further option, an evaluation software for statistical

evaluation and documentation can be supplied.

The QNix® 7500 complies to national and international

(DIN, ISO, BS, ASTM) standards and regulations:

DIN 50981, 50984

ISO 2178, 2360, 2808

BS 5411 (3 & 11), 3900-C5

ASTM B499, D 7091

The QNix® 7500 incorporates the latest electronic technol-

ogy in order to fulfill different measuring tasks. This high

precision instrument covers a wide range of applications,

yet it is robust and easy-to-use in every-day practice. If op-

erated and treated with care, it will serve you many years

producing accurate and reliable readings.

Do not let it drop and protect it from dirt, dust and other

substances. Protect the gauge from moisture, chemically

aggressive substances and/or gases.

After use, the gauge should be stored in its protective carry-

ing case.

Substantial changes in temperature can influence the read-

ings, as is the case with all precision gauges. Do not ex-

pose the gauge to strong, direct sunlight or to other sources

of energy causing temperature shocks.

The housing is resistant against most solvents. However a

resistance against all chemical substances cannot be guar-

anteed. Use only a damp, soft cloth to clean the housing.

Accurate readings can only be obtained, if the measuring

probe is clean. Check the probe regularly and remove resi-

dues such as lacquer etc. from the ruby tip.

If the gauge will not be used for a longer period, remove the

battery in order to prevent leakage and therefore destruc-

tion of the gauge.

In case of malfunction, please do not try to repair the gauge

yourself. Our repair service will be glad to assist at any

time.

The standard probes have a measuring range of

0-2000 µm or 0-80 mil (1 mil = 25.4 µm)

Optionally probes with a measuring range of up to 5000 µm

(200 mil) and right-angle-probes are also available.

The QNix® 7500 is operating either in µm or in mil only.

The unit is preset before shipping depending on the desti-

nation country. Gauges with memory QNix® 7500 M can be

switched from µm to mil using the optionally available soft-

ware.

The resolution depends on the thickness of the coating and

is as follows:

0.1 µm in the range of 0.0 - 99.9 µm

1 µm in the range of 100 - 999 µm

0.01 mm in the range of 1.00 - 2.00 (5.00) mm

0.01 mil in the range of 0.00 - 9.99 mil

0.1 mil in the range of 10.0 - 80 (100) mil

(1 mil in the range of 100 - 200 mil)

Storage: -10°C - 60°C (14°F - 140 °F)

Operating: 0°C - 50°C (32°F - 122 °F)

The QNix® 7500 is powered by a 9V alkaline battery. The

battery is located at the bottom end of the gauge. If the

blinking sign "BAT" appears in the display, it is advisable to

change the battery. However it is still possible to measure

for some time. Stored data will not be deleted when the bat-

tery is empty or while changing the battery.

A new zero-adjustment is required when using the gauge

for the first time, working with different materials, and after

inserting a new battery.

Place the probe of the QNix® 7500 on one of the zero

plates enclosed in the case. For measurements on ferrous

substrates use the steel zero plate, for non-ferrous applica-

tions use the aluminium plate or a respective uncoated

substrate.

Make sure the probe is placed rectangularly and evenly on

the surface of the zero plate or on your uncoated substrate.

If the value indicated is not within the basic tolerance, the

gauge should be adjusted (gauges with memory QNix®

7500 M must not be in the Memory Mode). Press the lower

red button C of the gauge while the probe is placed on the

zero plate, i.e. the substrate. You will hear a "beep" and a

control number will appear on the display. Lift the gauge or

the probe at least 10 cm (4 inches) from the zero plate. The

gauge will "beep" again and another number will be dis-

played. Now the QNix® 7500 is adjusted.

When repeating measurements on the same spot, the read-

ings may not always be 0.00 µm/mil, as the surface rough-

ness, dirt, scratches etc. might cause differences.

Place the probe evenly on the object to be measured. Place

the thumb directly above the probe. This ensures best han-

dling. The reading is immediately indicated on the display,

accompanied by a "beep". Simultaneously you will also re-

ceive the information, which probe, Fe or NFe, is presently

used in the gauge.

The most obvious advantage of the modular system QNix®

7500 is the universal application. Fe-, NFe-, and Dual-

Probes can be plugged firmly into the housing (internal

probe) or attached to it by an QNix® 7500 adapter cable

(external probe). In order to measure with a separate, ex-

ternal probe, the internal probe can be pulled out of the

housing. An optionally available QNix® 7500 adapter cable

with plug is inserted into the opening. Connect the probe to

the plug of the cable. This versatile coating thickness gauge

allows measurements even on hard-to-reach spots or on

difficult geometries. A special probe recognition system will

automatically tell you, which probe you are presently using.

If the QNix® 7500 or its probe is placed incorrectly, the dis-

play shows "Err" (error). The same message appears when

the probe is lifted before the measurement has been com-

pleted or when the probe is zeroed on a non-metallic sub-

strate.

If the measurements are out of range, the display shows

"InFi" (infinite). The same will be displayed, if measure-

ments on non-metallic substrates are taken.

The gauge automatically turns on, when the probe is placed

on the surface, and shuts off after approx. 10 sec, if it is not

used. The last reading is stored and appears again on the

display, when the upper right button M is pressed shortly.

When measuring on rod materials align the "V"-groove in

the ring of the probe with the rod.

Do not take measurements on magnetized parts!

Magnetic fields are likely to influence the readings of the

Fe-probe, strong electro-magnetic fields may influence all

measurements.

When using the Dual Probe, switching from Fe- to NFe-

measurements or vice versa is done as follows:

Switch on the QNix® 7500. The actual measuring method

Fe or NFe is displayed on the left side (e.g. Fe). Then press

the lower left button C for at least 3 seconds. A "beep" will

sound and the new measuring method is shown on the left

side of the display (e.g. NFe). To switch back to the other

method just press C again for 3 seconds.

In order to transfer data, the gauge has to be connected

through the optionally available interface cable with the

serial-port or the USB-port of a computer. To show the data

online, our QNix

software can be used or standard editing

programs.

Gauges with memory QNix® 7500 M are offering the follow-

ing features:

a) Storing up to 3900 readings

b) Block segmentation

c) Display of the mean value for each block

d) Display of the maximum value of each block

e) Display of the minimum of each block

f) Deleting the last reading or entire memory

g) Processing of the readings using the software

When the QNix® 7500 M is switched on, the gauge is in the

Normal Mode where no readings are stored.

To activate the Memory Mode, press the upper right button

M for approx. 1 second. Measurements in the Memory

Mode are accompanied by a double "beep". Approx. 2

seconds after the last reading has been taken the display

starts alternating to show the reading and the number "N" of

the reading, e.g. the display shows 125 µm (last reading)

and N 0014 (number of reading).

If no readings are stored in the memory the display alternat-

ing shows b001 and the sign "bloc", indicating that the read-

ings will automatically be stored in block 1.

To leave the Memory Mode, press the upper right button M

again. Notice: If pressed longer than 3 seconds, a new

block will be created.

The built-in memory can store up to 3900 readings. If the

gauge is out of memory, the display shows "End" for ap-

prox. 6 seconds. Then the last reading alternating with the

number of this reading is shown.

If no measurements are taken within 30 seconds, the gauge

switches off. The gauge automatically returns to the Normal

Mode if started again.

In the Memory Mode the readings can be stored in different

blocks, in order to distinguish the different tasks. Up to 999

blocks are available. In order to create a new block, press

the upper right button M while the gauge is in the Memory

Mode. Wait until the gauge beeps and the word "bloc" is

shown, alternating with the number of the new block (e.g.

"b002" for block no. 2). Other blocks can be created using

the same procedure. The size of the blocks may vary as

they are determined by the user only. If all 999 blocks have

been used, the display shows "End" for approx. 6 seconds

and a beeping alarm sounds.

Additionally, the gauge can display the mean, maximum,

and minimum value of the readings stored in the presently

used block. The gauge has to be switched on and be work-

ing in the Memory Mode. Press the lower left button C

shortly, while the gauge is lifted off the surface. The display

will show the sign "Ae" (average) and the average value in

µm, mm or mil alternating with "N" showing the number of

readings stored in this block. E.g. Ae 265 µm alternating

with N 0044 means, that in the active block the average

value is 265 µm and has been calculated out of 44 readings

stored in this block.

In order to display the maximum reading of the active block,

press the lower left button C again. The display will show

the sign  and the maximum reading. When pressing this

button again the minimum reading  of the active block is

displayed.

If no readings have been stored in the active block, it is not

possible to calculate statistical values. Then the display will

read "Ae no" alternating with "N 000".

The display of the mean-, minimum-, and maximum values

is not segregated into Fe and NFe measurements.

The QNix® 7500 allows to delete the last reading in the

memory as well as the entire memory. The procedure is as

follows:

Set the gauge to the Memory Mode. Then press the lower

left button C for at least 3 seconds while the gauge is lifted

off the surface. This function allows the user to eliminate er-

ratic readings that would falsify the statistics.

If all readings in a block are already deleted, the next delet-

ing process will eliminate the block as such, and the last

reading in the previous block will be displayed.

The entire memory content can be deleted by keeping the

button pressed for another 3 seconds after the last reading

has been deleted. The display shows "dEL" and "ALL" (al-

ternating) and a "beep" sounds. If the button is not released

within these 3 seconds, the entire memory content will be

deleted.

Deleting of the entire memory content can also be per-

formed with our optionally available software.

The built-in interface enables the gauge to process the

measured data statistically. The socket of the interface is

located at the bottom of the housing and is covered by the

lid of the battery compartment to prevent spoiling of the

socket. A software for statistical evaluation on your comput-

er is also available.

For further information concerning "Data Processing"

please refer to the software Instruction Manual.

All measurements of the QNix® 7500 or QNix® 7500 M

can be displayed online on the computer monitor.

The procedure is as follows:

Connect the probe with the gauge using the adapter cable.

The gauge itself has to be connected to the computer via

the interface cable. Each reading or other process, such as

calculation of mean, maximum, and minimum value, is di-

rectly displayed on the computer monitor. If the gauge

QNix® 7500 M is set to the Memory Mode, all readings will

additionally be stored so that the data can be processed

later.

If the last reading in the gauge is deleted, the monitor will

show the information "DELETED".
