10.3 Output Calibration
Calibration is done only after entering both zero and span values sequentially for separate
channels. For this we require a DMM of 6 1/2 Digits or more resolution. Input is not required while
retransmission output calibration.
Calibration of current or voltage (that depends on provided factory setting) is done in described
manner. In menu, first select the channel that has to be calibrated, monitor the output of that
corresponding channel using DMM (Digital Multi meter). The voltage /current terminals are common
and its selection is provided in factory setting. To calibrate the output, enter the zero option and
correct the value you see on the display with the value you see in the DMM. Do the same for the
Span too. Now select channel 2 and monitor the output of second channel and repeat the same
steps as performed for the first channel output.
It’s recommended to calibrate 0-20mA for current type output or 0-10V for voltage type
retransmission output, which again depends on provided factory setting.
