Fixed voltage Output Mode (Sub-maintenance Mode)

External devices which receive voltage or output from the master unit can undergo zero or span
adjustment in this mode as required. Select a 0V output to fix the voltage and current output to 0V
and 0 mA, respectively ( to 1V and 4mA if '1V to 5V' has been selected as the voltage output
range).
Select a 5V output to fix the voltage and current outputs to 5V and 20 mA, respectively. Leaving
this mode allows the voltage and current output to return to the ordinary state where the voltage
and current output are proportional to the speed.
The operation procedure is shown in the figure on the following page.

the display is at a. The display then changes to that
marked b, and a fixed voltage of 5V is output. If the
key is pressed while the display is at b, the
