speci fi ed thermistor or if other components such as a
capacitor is attached to the thermistor.
Use only the speci
fi ed thermistor.
• Check the contact between the DUT and the thermistor.
Even a slight gap will greatly affect the measurement
result.

An alarm indication is active.
• The charge/discharge power supply unit has detected
some kind of error and the test was aborted and is in an
alarm status.
Correct the problem by referring to section A.2, “Cause
of Alarms and Their Correction” in the
