8 Calibration of potentiometer input (CAL.Po)
9 Calibration of remote input 1 (CAL.S1)
10 Calibration of remote input 2 (CAL.S2)
11 Calibration of repetition output (CAL.rt)
Use the "Raise" and "Lower" keys to set the key code for the calibration step to be accessed (value 1-11). Then press the F key
to go directly to the step ONLY if the set code corresponds to a probe type conforming to instrument configuration (tYP); the
display will show the message corresponding to the type of calibration selected. If protection is active, you will exit the calibration
menu and return to display of the variable. By pressing the F key with key code = 0 you quit the calibration procedure and return
to display of the variable. The calibration check function signals (with message Er.CAL on the display) incorrect signal values
during calibration. The message is displayed when the difference between the maximum and minimum values of the signal is
less than 15% of the set full scale. In this situation, the outputs are forced to OFF state (relays de-energized). You have to re-run
the calibration procedure after removing the defect.
-CAL.L1 (per 0-50mV / 0-60mV / 0-100V linears)
Calibration (key code 1) for 50mV/60mV/100mV inputs. The display shows the message:
CAL.L1 Make electrical connections as instructed in specific section. Press the F key to continue.
CAL.0 Put a 0V signal between inputs of faston 1(+) and faston 2(-). Press the F key to continue.
CAL.50 Put a 50mV, 60mV or 100mV signal between inputs of faston 1(+) and faston 2(-). Press the F key to end the
procedure. The message _CAL with value 0 will appear on the display. Press the F key to exit the calibration menu or
set the code for a new calibration.
-CAL.L2 (for 0-1V linears)
Calibration (key code 2) for 1V input. The display shows the message:
CAL.L2 Make electrical connections as instructed in specific section. Press the F key to continue.
CAL.0 Put a 0V signal between inputs of faston 1(+) and faston 2(-). Press the F key to continue.
CAL.1 Put a 1V signal between inputs of faston 1(+) and faston 2(-). Press the F key to end the procedure. The message
_CAL with value 0 will appear on the display. Press the F key to exit the calibration menu or set the code for a new
calibration.
-CAL.L3 (for 0-1V linears)
Calibration (key code 3) for 0-10V input. The display shows the message:
CAL.L3 Make electrical connections as instructed in specific section. Press the F key to continue.
CAL.0 Put a 0V signal between inputs of faston 1(+) and faston 2(-). Press the F key to continue.
CAL.10 Put a 10V signal between inputs of faston 1(+) and faston 2(-). Press the F key to end the procedure. The message
_CAL with value 0 will appear on the display. Press the F key to exit the calibration menu or set the code for a new
calibration.
-CAL.L4 (for 0-20mA / 4-20mA linears)
Calibration (key code 4) for 0-20mA / 4-20mA input. The display shows the message:
CAL.L4 Make electrical connections as instructed in specific section. Press the F key to continue.
CAL.0 Put a 0mA signal between inputs of faston 1(+) and faston 2(-). Press the F key to continue.
CAL.20 Put a 20mA signal between inputs of faston 1(+) and faston 2(-). Press the F key to end the procedure. The message
_CAL with value 0 will appear on the display. Press the F key to exit the calibration menu or set the code for a new
calibration.
-CAL.S (for 6-4 wire strain gauge pressure probe)
Calibration (key code 5) for pressure input for 4 or 6-wire strain gauge probe with manual sequence.
The display shows the message:
CAL.SG Make electrical connections as instructed in specific section. Use the "Raise/Lower" keys to set the calibration value
indicated on each probe, approximately 80% of full scale. Press the F key to continue.
PrS.1 Put a signal corresponding to minimum pressure (equivalent to probe drained) between inputs of faston 1(+) and faston
2(-).Press the F key to continue.
PrS.2 In case of 6-wire probe, the instrument will automatically unbalance the pressure probe and acquire the calibration value.
Attention: the probe must be drained.
In case of 4-wire probe, put a signal corresponding to the set calibration value at instrument input, or load the probe in
an equivalent manner. Press the F key to end the procedure. The message _CAL with value 0 will appear on the
display. Press the F key to exit the calibration menu or set the code for a new calibration.
