PFX2000 Maintenance 4-7
■
Symptom 6: The ALARM/WARNING LED is illuminated in
orange in the Idle status.
■
Symptom 7: Correct voltage/current is not indicated.
Check Item Cause and Remedy
The protection function has tripped. • Some of the protection functions (H_OVP, H_UVP, and
Conn) of the charge/discharge power supply unit are
functional even when the charge/discharge test is not in
progress (Idle).
Correct the problem by referring to section A.2, “Cause
of Alarms and Their Correction” in the
BPChecker2000
User’s Manual .
Check Item Cause and Remedy
The readout error is large.
• The error may be large immediately after the power is
turned on due to initial temperature drift.
Check again after waiting for the readout to stabilize
(approximately 10 minutes).
• There is a tendency for the error to become large in
minute voltage or current measurements due to effects
from peripheral noise or internal power supply noise.
In this case, using the moving average setting some-
times improves the situation. For setting the moving
average, see section 4.3.1, “Module” in the
BPChecker2000 User’s Manual .
• In average pulse current measurements, the error some-
times become large depending on the pulse time width
or current setting.
• If the dust fi lter is clogged and the internal temperature
of the charge/discharge power supply unit rises abnor-
mally, the error increases due to the temperature drift of
the measurement circuit and other components.
Clean the dust
fi lter.
• If the error is large under all conditions, the calibration
may be off.
Contact your Kikusui agent or distributor to have the
unit calibrated.
The voltage readout is unstable.
• If you connect an object other than a battery as a DUT,
the voltmeter readout may be unstable.
• If the power to the frames is supplied by a source other
than a commercial AC power supply, the voltmeter
readout may be unstable.
Connect to a commercial AC power supply.
• If the GND wire of the power cord is not connected, the
voltmeter readout may be unstable.
Ground the unit correctly by referring to section 1.5,
“Grounding.”
