Output current calibration
1
Without exiting the calibration mode, turn the rotary switch to any one of the
“Current Input/Voltage Output” positions.
2
Connect the output terminals to a recommended multimeter (refer to
on page 142 for the recommended test equipment).
Follow the steps below to perform calibration for the output voltage ranges and
values listed in
:
1
As you enter each calibration step, the primary and secondary displays show
the
output current value
and “-rdy-” respectively.
2
Press
OUTPUT
. The primary and secondary displays show the
output current
value
and “00000” respectively, which means the present output level is as
shown on the primary display.
3
Press
or
to adjust the output current until the multimeter reading is
the same as the value shown on the primary display.
4
Press
MODE
to enter the next calibration step.
At the end of the last calibration step, the primary display will show “PASS” after
the
MODE
button is pressed.
