4.2 Setting Basic Settings of Measurement Conditions
54
This function operates when measurement is being performed in low impedance high accuracy mode (p.
53). It detects whether each of the L
POT
, H
POT
and L
CUR
terminals is disconnected.
If a terminal is not connected properly, an indication like the following is displayed.
Check the connections again.
See "2.4 Connecting the Measurement Cables, Probes, or Fixture" (p. 30)
The error is also output via EXT I/O.
See "Chapter 11 External Control" (p. 363)
With low Z high accuracy mode, the possible setting ranges of the frequency and measure-
ment signal level differ. Refer to the following.
Settable range of measurement signal level: (p. 45)
Low Z high accuracy mode is only valid when the frequency is between 4 Hz and 100 kHz.
Detecting Disconnection of 4 Terminals
(When Low Z High Accuracy Mode)
When an element other than a capacitor or a capacitor with a low DC resistance is measured
while using DC bias, the contact check function may not work properly.
No.
