Adjusting Analog Outputs
In the analog output calibration the analog output is forced to the
following values:
current output
= 2 mA and 18 mA
voltage output
= 10 % and 90 % of the range
Connect DMT340 to a calibrated current/voltage meter in order to
measure either current or voltage depending on the selected output type.
Use the display/keypad or the serial line to do this.
