Make sure that the type of input to be used in the calibration of output is already
well calibrated.
Make connections listed in the table below depending on the type of output you
want to calibrate.
Enter the calibration level 8, select the type of output (4-20 mA, 1-5 V or 0-10 V)
and press ENTER. The display will show the corresponding mnemonic to the first
calibration point. There are only two output calibration points.
In the case of current output the mnemonics correspond to electrical signals of 0
and 20 mA. For the voltage output, the signals correspond to the mnemonics of 0 and 5 V
or 0 and 10 V.
Pressing ENTER after the exhibition of the corresponding mnemonic to the first or
second calibration point the display goes on to show the output value.
You can then through the UP and DOWN keys to adjust the output value for the
electric level presented by mnemonics. After adjusted, press the ENTER key.
In the first calibration point (0 mA, 0 V) must be careful not to saturate the
output signal.
You can then return to normal operating mode down until the level zero.
Return to factory calibration
The indicator remains in the non-volatile memory values of the factory calibration
parameters which can be retrieved at any time.
When it is suspected that an instrument malfunction is due to a recalibration badly
done should make use of RECOVERY option (see Figure 25).
REC - is the option that allows the recovery of the factory calibration values. It is
an option both for input and output.
Enter the level 8 Calibration and choose whether the recovery should be
performed for the input or the output. Select the RECOVERY option and press ENTER to
reload the factory configuration
