4.3 Setting DC Resistance Measurement
68
Relationship between the measurement signal level of the instrument and the sample is as follows.
• When normal mode (p. 74)
• When Low Z high accuracy mode (p. 74)
• When normal mode (p. 74)
• When Low Z high accuracy mode (p. 74)
• When normal mode (p. 74)
• When Low Z high accuracy mode (p. 74)

Constant current level (CC)
You should select this if you wish
to set the current passing through
the object to be tested to a con-
stant value.
Constant voltage level (CV)
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 level (V)
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.
