5.4 SETUP MENU EXPLANATIONS

5.4.1 MENU 1: LEVEL

Calculating the Span for Level

The Span is used to convert the sensor output current to a level. The basis is the level at 20 mA

sensor signal. Two examples are given.

User Manual F073-A

Page 14 FW_F073-A_M_v0501-03_EN

Example 1 (no offset)

● The sensor generates 20 mA at a level of 2,481.3 Liters.

● The quantity will be displayed using L (1.1: LEVEL > UNIT), with 1 decimal (1.2: LEVEL > DECIMALS).

● Thus, the span is 2,481.3.

● Enter the Span as 24813 at 1.3: LEVEL > SPAN and 0 at 1.4: LEVEL > OFFSET.

Example 2 (with offset)

● The sensor generates 4 mA at a level of 200 USGAL and 20 mA at 652.31 USGAL.

● The quantity will be displayed using USGAL (1.1: LEVEL > UNIT), with two decimals (1.2: LEVEL >

DECIMALS).

● The Span is 652.31 – 200 = 452.31.

● Enter the Span as 452.31 at 1.3: LEVEL > SPAN and 200.00 at 1.4: LEVEL > OFFSET.

When a different unit is selected, the displayed values are NOT recalculated.

1 LEVEL

1.1 UNIT Determines the measurement unit for the displayed level. The following

units can be selected:

L - m3- kg - lb - GAL - USG - bbl - no unit

Changing the measurement unit will have consequences for operator

and setup values. Please note that the Span should be checked also.

Recalculation is not done automatically.

1.2 DECIMALS Determines for Level and its Span the number of digits after the decimal

point.

1.3 SPAN This value is used to convert the sensor output to a level. The Span is

based on the actual level at 20 mA sensor signal, and the selected

measurement unit, as defined in 1.1: LEVEL > UNIT.

Accuracy of the measurement system depends on the accuracy of the

Span.

Examples are given just above this table.

1.4 OFFSET Enter the "not measured" quantity which is present at sensor output

zero.

When necessary a negative offset can be entered: press the ► and ▲

button simultaneously.

5.4.2 MENU 2: HEIGHT

Calculating the Span for Height

The Span is used to convert the sensor output current to a height. The basis is the actual height at

20 mA. An example follows.

Example

● The sensor generates 4 mA at a height of 21.4 cm water column (cmwc) and 20 mA at 4245.8

cmwc.

● The height will be displayed using cmwc (2.1: HEIGHT > UNIT) with 0 decimals (2.2: HEIGHT >

DECIMALS).

● Thus, the span is 4245.8 – 21.4 = 4224.4.

● Enter 4224 at 2.3: HEIGHT > SPAN and 21 at 2.4: HEIGHT > OFFSET.

2 HEIGHT

2.1 UNIT Determines the measurement unit for the displayed height. The following

units can be selected:

m - mm - cm - mtr - inch - ft - mmwk - mmwc - cmwk - cmwc - mwk -

mwc - inwc - ftwc - mbar - bar - psi - no unit

Changing the measurement unit will have consequences for operator

and setup values. Please note that the Span should be checked also.

Recalculation is not done automatically.

3.1 EMPTY When the sensor signal is zero, the monitoring can be ignored or

disabled. Select the desired action when the signal becomes zero:

●Default: the alarm output is switched, and the alarm is indicated on

the display.

●No relay: the alarm output is not switched, but the alarm is indicated

on the display.

●Ignore: the alarm output is not switched, and no alarm is indicated

on the display.

3.2 ALARM LOW Sets the low alarm threshold. An alarm is generated as long as the Level

is lower than this setting. The function is disabled by entering 0.0.

3.3 ALARM HIGH Sets the high alarm threshold. An alarm is generated as long as the

Level is higher than this setting. The function is disabled by entering 0.0.

3.4 DELAY ALARM LOW An alarm generated by 3.2: ALARM > ALARM LOW can be ignored during X-

time period. If the Level is still below the Alarm Low level after this delay

time, an alarm is generated.

3.5 DELAY ALARM HIGH An alarm generated by 3.3: ALARM > ALARM HIGH can be ignored during X-

time period. If the Level is still above the Alarm High level after this delay

time, an alarm is generated.

5.1 LCD UPDATE Sets the LCD display refresh rate. The following can be selected:

fast - 1 sec - 3 sec - 15 sec - 30 sec - off

When a key is pressed, the display refresh rate will switch to ‘fast’ for 30

seconds. After this the refresh rate will return to the set update rate.

Please note that no information will be lost at low refresh rates: all

sensor input will be processed in the background.

Calculating the display information significantly affects the power

consumption. When the application does not require a fast display

refresh rate, it is strongly advised to select a slow rate.

Indication of expected battery life:

●5.1: POWER MANAGEMENT > LCD UPDATE set to fast: 2 years

●5.1: POWER MANAGEMENT > LCD UPDATE set to 1sec: 5 years.

5.2 BATTERY MODE The F073-A has two main modes: operational and shelf mode. In shelf

mode the product can be stored for several years with extremely low

power consumption from the battery. All settings and totals are

maintained in memory.

To wake up the F073 from shelf mode, simply press the ▲ key twice.

5.4.6 MENU 6: SENSOR

6 SENSOR

6.1 FILTER The analog output signal of a level sensor mirrors the actual process

value. This signal is sampled several times per second by the F073-A.

Consequently, random and/or fast changes in sensor signal may lead to

instable displayed process values. With the help of the filter setting a

stable and accurate reading can be obtained. The filter function is based

on three values: the last sampled input signal, the last average value

and the set filter level. The higher the filter level chosen, the slower the

response of the unit to step changes in the process value will be.

The table below gives response times related to filter levels.

6.2 CUT-OFF To ignore small signals in sensor output, a low level cut-off can be set as

percentage of the full range of 16 mA (or 20 mA), and can be set from

0.0 to 99.9 %. If the input is below cut-off, the signal will be ignored. An

example follows.

EXAMPLE OF CUT-OFF CALCULATION

Span Cut-off Cut-off percentage Threshold input signal

6.3 CALIBRATE LOW The unit is calibrated in factory using a very accurate current source. In

case the sensor signal does not equal (0)4mA at the offset level, this

function is needed to set the minimum input current at minimum level.

Be very sure that the offered tuning signal is stable and correct

before using it for calibration, since this setting has major

influence on the accuracy of the system.

The input loop powered version of the F073-A (Type PL) requires an

input signal of at least 4 mA, not lower.

After pressing PROG, one of three options can be selected.

●CALIBRATE: with this choice, the minimum input will be set at the

actual input current. After pressing ENTER, CAL SET will be

displayed when the calibration process is completed. From now on,

the input current must be higher than the newly calibrated value in

order to be processed.

●DEFAULT: re-installs the factory calibration.

●CAL SET: selects the latest calibrated value.

6.4 CALIBRATE HIGH The F073 is calibrated in factory using a very accurate current source. In

case the sensor signal does not equal 20mA at maximum level, this

function is needed to set the input current at maximum level.

Be very sure that the offered tuning signal is stable and correct

before using it for calibration, since this setting has major

influence on the accuracy of the system.

After pressing PROG, one of three options can be selected.

●CALIBRATE: with this choice, the maximum input will be set at the

actual input current. After pressing ENTER, CAL SET will be

displayed when the calibration process is completed. From now on,

the input current must be lower than the newly calibrated value in

order to be processed.

●DEFAULT: re-installs the factory calibration.
