3.2 Output Verification
IT6860B is dual range output, the following procedures verify that the power supply outputs
the correct voltage and current levels and properly responds to entries from the front panel.

．
Voltage Output Check
The following steps verify basic voltage functions without load.
High voltage range voltage check
：
1) Turn on the power supply
2) Press
I-set
I-set
to set the current value (
≥
0.0001A).
3) Enable the outputs
Press
On/Off
to let the ON annunciator and the CV annunciator turn on to light.
4) Turn on Meter mode
Press
Meter
Meter
to light the button, the Meter status Mark light on the display is turned
on.
Notice
:
if the voltage value flash, then the power supply is in Set mode, ‘‘Set mode’’
means that the VFD display shows the setting output voltage and current. Or the
power supply is in Meter mode, ‘Meter mode” means that the VFD display shows the
actual output voltage and current.
5) Press
(Shift) +4 to switch to high voltage range, and then set the voltage level.
Set different voltage values, check the voltage value displayed on the VFD is close to
the voltage value you set, and to check if the VFD displayed current value is nearly
zero.
6) Ensure that the voltage can be adjusted from zero to the full rated value
Low voltage range voltage check
：
7) Press
(Shift) +7 in the above step 5 instead to switch to low voltage range, and
then repeat step 5~6

Current Output check
The following steps check basic current functions with a short across the power supply’s
output.
High voltage range current check
：
1) Turn on the power supply
2) Enable the output
Press
On/Off
key to ensure that the output is disabled. At the same time, the OFF status
mark is on the VFD.
3) Connect a short across (+) and (-) output terminals with an insulated test lead, use a wire
sufficient to handle the maximum current.
4) Adjust the voltage value to 1V.
5) Turn on the power output.
Press
On/Off
key to ensure the output is enabled, at the same time there is CC status
sign on the VFD.
6) Turn on Meter mode
Press
Meter
Meter
to light the button, the Meter status Mark light on the display is turned on.
