Setting Measurement Conditions (basic settings)
Limit (limiting the voltage and current applied to the sample) (AC)
Depending on the measurement signal level, in some cases it is possible to damage the sample
which is being measured by applying to it a voltage or a current greater than its rated value.
(See"Constant voltage (CV) mode" (p. 53), and "Constant-current (CC) mode operation" (p. 53).)
To prevent such damage, you can set limits on the voltage that will be applied to the sample or the
current that will flow to the sample.
Enabling the limit function increases the measurement time (due to the use of software feedback
control).
When open circuit voltage (V) mode or constant voltage (CV) mode is set
Set the current limit.
When constant current (CC) mode is set
Set the voltage limit.

Use the
key to enter the limit value.
You can check the voltage and current between
the sample terminals using monitor values. Moni-
tor values differ depending on the measurement
signal mode setting (V, CV, CC).

•
First set the measurement signal level, and
thereafter set the voltage or current limit.
•
The screen used to set the limit function
varies depending on the measurement
signal mode that has been selected (V, CV
mode: current limit; CC mode: voltage limit).
