Function specications
Contact check
function
Operation details Judges the contact condition by comparing a measured value with
the judgment reference value.
Operation method Capacity measurement method by applying a high frequency
signal
Automatic execution
ON/OFF
Capacity
measurement
accuracy range
0.200 pF to 95.000 pF
(However, the capacity of the object to be measured shall be
equal to or greater than 1/10 of the xture capacitance.)
Capacity
measurement
accuracy
±(20% of the read value ±0.1 pF)
Judgment reference
value input range
0.00 pF to 99.99 pF
Judgment GO: (Measured capacity value) > (Judgment reference value)
NG: (Judgment reference value) ≥ (Measured capacity value)
Variable frequency
300 kHz / 245 kHz
Frequency accuracy ±20%
Capacitance setting
of objects to be
measured
LOW/NORMAL
Self-calibration
function
Operation details Corrects the o󰀨set voltage and the gain of the measurement
circuit.
Setting
ON/OFF
Setting time
1 s to 600 s
Others Automatically executes the correction once when the instrument is
turned on and 5 minutes later regardless of whether the setting is
ON or OFF.
The correction can be manually executed once from the ON/OFF
settings screen.
The self-calibration can be executed by sending the command
even when the setting is OFF.
