Press ENTER after the display shows the mnemonic related to first or second
point of calibration, so that the display starts to show the output value. Then use the
UP and DOWN keys to set the output value to the electric level indicated by the
mnemonic. After the output value is set, press ENTER. During the first point
calibration (0mA, 0V) be careful not to saturate the output signal.
Finally, return to normal mode by moving down through the levels until
reaching level zero.
Return to factory calibration
The Indicator stores the factory calibration parameter values on the non-
volatile memory, which may be recovered at any time.
In case of a bad performance of the instrument due to an incorrect calibration,
use the REC option (see figure 28).
REC - is the option that allows to recover the factory calibration.
Enter level 5 of Calibration, and choose the INPUT or the OUTPUT option.
Select the REC option and press ENTER in order to recover the values from factory.
4.6 - Hardware maintenance instructions
Before sending the instrument back to factory check the following probable
causes of a malfunctioning Indicator.
Instrument with error indication on display
After turning the instrument on, it tests RAM and E2PROM integrity.
When at least one of these components presents some problem the display
shows the following error codes:
Err. 01 - RAM error
Err. 02 - E2PROM error
In case of RAM error, turn the instrument off and on to check if the error
message is displayed again. If the error remains, return the instrument to factory.
When there is E2PROM error, press the ENTER key and configure the
instrument again. Turn the instrument off and on to check if the error message is
displayed again. If the error remains, return the instrument to factory.
During configuration the display can show the Err.03 error message.
This error can happen when trying to assign a different configuration (analog
output, alarm or preset) to an output already configured and enabled. In order to
avoid this case, do not forget to disable relays 1 and 2 before enabling analog
output 1 and 2 and vice-versa.
Note: When configuring a relay module as an analog output, the relay
will be activated and deactivated continuously.
