Starting/Stopping Measurement
3.6 Starting/Stopping Measurement
Be sure to read “Before performing a measurement” (p. 12) beforehand.
Internal trigger (INT) (default
setting)
Pressing the START key results in a measurement voltage applied, and
then starts a measurement.
Pressing the STOP key stops applying the voltage and the
measurement.
External trigger (EXT) Pressing the START key results in a measurement voltage applied.
Inputting a trigger signal starts a measurement.
Pressing the STOP key stops applying the voltage.
• An measurement voltage is reduced to 0 V when the measurement is stopped. No trigger cannot be
accepted.
• A voltage between the OUTPUT terminal and the INPUT terminal is discharged (placed in a discharge
state with the current limiter connected). (The output of the CHARGE terminal is basically the same as
the OUTPUT terminal. Therefore, the CHARGE terminal is also discharged in a manner similar to the
OUTPUT terminal.)
3.7 Conrming Measurement Results
Detecting a measurement abnormality
If the measurement is not correctly performed, an error message appears on the screen, and ERR
signal is output from EXT I/O terminal.
See “Measurement errors” (p. 161).
Temperature measurement indication
If the Humidity Sensor is not connected to the instrument
(Display: [--.--°C], [--.-%rh])
The Humidity Sensor is not connected to the instrument. Thus, temperature cannot be measured.
If the temperature measurement is not necessary, connecting the Humidity Sensor to the instrument
is not required.
Out-of-range indication
The out-of-range indication for each of the parameters is displayed due to causes listed below.

Resistance value
[Current Over Range]
The measured value exceeds the indication range
of the present current range.
* This means that the resistance is low.

Temperature
[+Over°C] The measured value is greater than 80.0°C.
[-Over°C] The measured value is smaller than -40.0°C.
Humidity [Over%rh] The measured value is greater than 90%RH.
