PAS SERIES Maintenance 7-19
Symptom4: The output is unstable.
Check Item Cause and Remedy
□
The operation mode
switches from CV to
CC or CC to CV. • Change the setting (VOLTAGE or CURRENT)
that is limiting the output to a value greater than
the current setting. If the preset value is at maxi-
mum, you must use a power supply with a larger
output voltage or current. See "2.3 CV Power Sup-
ply and CC Power Supply".
□
Parallel operation or
series operation is
enabled. • The performance when master-slave parallel oper-
ation or master-slave series operation is enabled is
slightly lower than when the unit is operating as a
standalone.
□
Remote sensing in
CONFIG is turned on. • If you are not using the remote sensing function,
turn off remote sensing in CONFIG.
□
30 minutes has not
elapsed since the power
was turned on. • The output is unstable due to initial drift. Warm up
(power turned on) the unit for at least 30 minutes.
□
Both "CV" and "CC"
indications are on. • If the output is oscillating when using remote sens-
ing, insert a capacitor across the load.
The internal circuitry may have malfunctioned.
• Immediately stop the use of the instrument and
request for repairs.
□
The ammeter indica-
tion is greater than the
display error even with-
out a load connected. • The internal circuitry may have malfunctioned.
□
Output is generated
even when the OUT-
PUT switch is turned
off. • The internal circuitry may have malfunctioned.
