About the measurement signal mode
Relationship between the measurement signal mode of the instrument and the sample is as fol lows.

Constant current (CC) mode
You should select this if you wish to set the
current passing through the object to be
tested to a constant value.
Constant voltage (CV) mode
You should select this if you wish to set the
voltage across the terminals of the object
to be tested to a constant value.
Open circuit voltage (V) mode
This voltage value is the value which is applied across
the two terminals of the series combination of the object
which is being tested and the output impedance. As for
the voltage which is applied across the terminals of the
object which is being tested (by itself), if required, you
should either check the monitor voltage value, or select
constant voltage (CV) and set a voltage value across
these terminals.
Measurement
sample
Constant-voltage (CV) mode operation
When the sample’s impedance is higher than the previous measurement, a voltage that is greater than the set
voltage level will be applied, and this may damage the sample. This is due to the fact that the output voltage
is controlled, and the set voltage level applied, by means of a software feedback process that observes the
voltage across the sample’s terminals when the same voltage level is applied as during the previous measure -
ment.
Constant-current (CC) mode operation
When the sample’s impedance is less than the previous measurement, a current that is greater than the set
current level may be applied. This is due to the fact that the output voltage is controlled, and the set cur -
rent level applied, by means of a software feedback process that observes the voltage across the sample’s
terminals when the same voltage level is applied as during the previous measurement.
