CAT IV A CAT IV-rated meter is suitable for measuring in CAT I-, CAT II-

and CAT III-environments as well as on the primary supply level.

Note that for all measurements on equipment for which the supply

cables run outdoors (either overhead or underground) a CAT IV

meter must be used.

Warning: this device was designed in accordance with EN 61010-1

installation category CAT II 600V. This implies that certain restrictions in use

apply that are related to voltages and voltage peaks which can occur within

the environment of use.

• This device is suitable for measurements up to 600V in CAT II:

measurements in CAT I-environments and mono-phase appliances that

are connected to the mains by means of a plug and circuits in a normal

domestic environment, provided that the circuit is at least 10m apart from

a CAT III- or 20m apart from a CAT IV-environment. E.g. household

appliances, portable tools…

RESISTANCE

• Connect the red test lead to the "VΩmA" jack [9] and the black test lead

to the "COM" jack [7] (the red lead has a positive polarity "+").

• Set the rotary switch [3] in the "Ω" range position.

• Connect the test leads to the resistor to be measured and read the LCD

display.

• If the resistance being measured is connected to a circuit, turn off the

power and discharge all capacitors before applying the test probes.

Note:

wait a few seconds for a stable reading when measuring resistors >

DIODE TEST AND AUDIBLE CONTINUITY TEST

• Connect the red test lead to "VΩmA" jack [9] and the black one to the

"COM" jack [7] (the red lead has a positive polarity "+").

• Set the rotary switch [6] in the position and use the select button

[3] to choose between diode or continuity test. Do not apply input

voltage at this setting!

• For diode tests, connect the red test lead to the anode of the diode to be

tested and the black test lead to the cathode of the diode. The approx.

forward voltage drop of the diode will be displayed. If the connection is

reversed, the display will show “OL”.

• For continuity tests, connect the test leads to two points of the circuit to

be tested. If continuity exists, the built-in buzzer will sound.

Notes:

forward DC current: ±0.5mA

backward DC voltage: ±1.5V

open circuit voltage: ±0.5V

buzzer sounds when resistance < 50

TEMPERATURE

• Set the rotary switch [6] in the °C/°F position and use the select button

[3] to choose between °C and °F. Do not apply input voltage at this

setting!

• Insert the cathode (black pin) in the "COM" jack [7], and the anode (red

pin) in the "VΩmA" jack [9].

• Use the other end of the thermocouple to measure temperatures.

Velleman® Service and Quality Warranty

Velleman® has over 35 years of experience in

the electronics world and distributes its

products in more than 85 countries.

All our products fulfil strict quality

requirements and legal stipulations in the EU.

In order to ensure the quality, our products

regularly go through an extra quality check,

both by an internal quality department and by

specialized external organisations. If, all

precautionary measures notwithstanding,

problems should occur, please make appeal to

our warranty (see guarantee conditions).

General Warranty Conditions Concerning

Consumer Products (for EU):

• All consumer products are subject to a 24-

month warranty on production flaws and

defective material as from the original date of

purchase.

• Velleman® can decide to replace an article

with an equivalent article, or to refund the

retail value totally or partially when the

complaint is valid and a free repair or

replacement of the article is impossible, or if

the expenses are out of proportion.

You will be delivered a replacing article or a

refund at the value of 100% of the purchase

price in case of a flaw occurred in the first year

after the date of purchase and delivery, or a

replacing article at 50% of the purchase price

or a refund at the value of 50% of the retail

value in case of a flaw occurred in the second

year after the date of purchase and delivery.

• Not covered by warranty:

- all direct or indirect damage caused after

delivery to the article (e.g. by oxidation,

shocks, falls, dust, dirt, humidity...), and by

the article, as well as its contents (e.g. data

loss), compensation for loss of profits;

- frequently replaced consumable goods, parts

or accessories such as batteries, lamps, rubber

parts, drive belts... (unlimited list);

- flaws resulting from fire, water damage,

lightning, accident, natural disaster, etc. …;

- flaws caused deliberately, negligently or

resulting from improper handling, negligent

maintenance, abusive use or use contrary to

the manufacturer’s instructions;

- damage caused by a commercial, professional

or collective use of the article (the warranty

validity will be reduced to six (6) months when

the article is used professionally);

- damage resulting from an inappropriate

packing and shipping of the article;

- all damage caused by modification, repair or

alteration performed by a third party without

written permission by Velleman®.

• Articles to be repaired must be delivered to

your Velleman® dealer, solidly packed

(preferably in the original packaging), and be

completed with the original receipt of purchase

and a clear flaw description.

• Hint: In order to save on cost and time,

please reread the manual and check if the flaw

is caused by obvious causes prior to presenting

the article for repair. Note that returning a

non-defective article can also involve handling

costs.

• Repairs occurring after warranty expiration

are subject to shipping costs.

• The above conditions are without prejudice to

all commercial warranties.

The above enumeration is subject to

modification according to the article (see

article’s manual).

Velleman® service- en kwaliteitsgarantie

Velleman® heeft ruim 35 jaar ervaring in de

elektronicawereld en verdeelt in meer dan 85

landen.

Al onze producten beantwoorden aan strikte

kwaliteitseisen en aan de wettelijke bepalingen

geldig in de EU. Om de kwaliteit te

waarborgen,

ondergaan onze producten op regelmatige

tijdstippen een extra kwaliteitscontrole, zowel

door onze eigen kwaliteitsafdeling als door

externe gespecialiseerde organisaties. Mocht er

ondanks deze voorzorgen toch een probleem

optreden, dan kunt u steeds een beroep doen

op onze waarborg (zie waarborgvoorwaarden).

Algemene waarborgvoorwaarden

consumentengoederen (voor Europese

Unie):

• Op alle consumentengoederen geldt een

garantieperiode van 24 maanden op productie-

en materiaalfouten en dit vanaf de

oorspronkelijke aankoopdatum.

• Indien de klacht gegrond is en een gratis

reparatie of vervanging van een artikel

onmogelijk is of indien de kosten hiervoor

buiten verhouding zijn, kan Velleman®

beslissen het desbetreffende artikel te

vervangen door een gelijkwaardig artikel of de

aankoopsom van het artikel gedeeltelijk of

volledig terug te betalen. In dat geval krijgt u

een vervangend product of terugbetaling ter

waarde van 100% van de aankoopsom bij

ontdekking van een gebrek tot één jaar na

aankoop en levering, of een vervangend

product tegen 50% van de kostprijs of

terugbetaling van 50 % bij ontdekking na één

jaar tot 2 jaar.
