3.3 Setting the Measurement Conditions

Set the measurement signal level.
Set a signal level appropriate for the sample to be measured.
Press to change the mode.
Measurement signal level:
100 mV, 500 mV, 1 V
The selected item is indicated by the lit LED lamp.
When the set voltage is applied to both sides of the sample, the CV indicator
lights up. The CV indicator does not light up when the applied voltage is lower
than the set voltage. In such a case, the EXT I/O outputs a ERR signal.
3.3.3 Measurement Signal Level
A voltage of ±12 V is generated at the L
CUR
terminal when the L
POT
and L
CUR
terminals are in an open state.
100 mV
(Model 3504-60
only)
500 mV
Constant-voltage measurement can be performed within the
range of 0.94 pF up to 170

F (1 kHz) or 9.4 pF up to 1.45 mF
(120 Hz).
1 V Constant-voltage measurement can be performed within the
range of 0.94 pF up to 70

F (1 kHz) or 9.4 pF up to 0.7 mF (120
Hz).

• In some samples, the value may vary depending on the measurement-sig-
nal level.
• Constant voltage measurement may not be possible if the value of the con-
tact resistance between the measurement terminals and the sample is high.
When this is the case, “CV_Lo ” appears on the MAIN display area, CV LED
goes out, and a ERR signal is output from EXT I/O.
• When confirming the measurement signal level with a voltmeter, connect
Hcur and Hpot, and Lcur and Lpot, to confirm the voltage between H and L.
Turn the trigger synchronous output function OFF when doing so.
