Symptom Items to check and possible remedy
The POWER/STANDBY LED does
not light even when the POWER
switch is turned on. Is the power cord connected properly? p. 28
Are the cables between the devices connected properly?
p. 30
The ALARM/WARNING LED is lit
when the POWER switch is
turned on. In rare cases, the ALARM/WARNING LED lights red. This is due to a
power interruption being detected depending on the timing of
turning on the power switch. This is not an error. Turn off the power
switch, wait at least 5 seconds, and the turn it on again.

The displayed value is strange. Is the front panel display showing the appropriate item that you want
to view?

The display error is large. Error may be large immediately after turning the power on due to the
initial temperature drift. Wait for the temperature to stabilize (about 30
minutes), and then check again.
p. 78
If the dust filter is clogged and the internal temperature rises, errors
will increase due to the temperature drift of measurement circuits and
the like.
Clean the dust filter.

If errors are large even under different conditions, the product

The voltage display is unstable. If the connected DUT is not a battery or if the DUT is connected yet to
another device, the voltmeter display may be unstable.

Is the ground wire of the power cord grounded? If it is not grounded
properly, the voltmeter display may fluctuate. p. 28

The test data results are
unstable. Is the chassis terminal connected?
Connections between devices may be affected by noise. To prevent
malfunction, acquire accurate test data, and perform charge /
discharge tests safely, we recommend that you connect the chassis
terminal.
