4.4 Setting the Test Signal Level
────────────────────────────────────────────────────
4.4.2 Selecting the Level Type
CAUTION
Be absolutely sure not to change over between constant current (CC) level
and constant voltage (CV) level with the test terminals still connected to the
sample to be tested. Doing so may damage the test sample.

The digit keys (If held down continuously, the corresponding digit increments
or decrements continuously.) (If the limit for the corresponding digit is reached,
these keys change to non-reversed video and become inactive.)
The key corresponding to the currently established type o
test signal level is shown in non-reversed video.

NOTE
1. Press the key on the Initial screen to display the Menu screen.
2. Press the key on the Menu screen to display the Test signal level
setting screen.
The current situation can be checked using the monitor display.
3. The method of control for the test signal level can be selected from the
following three:
Set open circuit voltage (V) The value of the open circuit voltage is set.
Set constant voltage (CV) The value of the voltage between the terminals
of the object under test is set.
Set constant current (CC) The value of the current flowing through the
object under test is set.
The accuracy of testing varies according to the test signal level. Check the
accuracy table in Section 7.5.
