1. Measurement range
You can switch the measurement mode according to the voltage to be measured.
Switch the measurement mode to match the application.
2. Averaging rate
Set the averaging of the data acquired at the sampling rate.
z Averaging rate
The average value is the moving average. If the measured values fluctuate, stable
measurements can be obtained by increasing the average count.
Measurement range Description
Default
value
High-precision mode
Measurement can be performed in the range of 0 to
±2 kV and the reference distance for measurement
is 25 mm.
c
Wide-range mode
Measurement can be performed in the range of 0 to
±50 kV and the reference distance for
measurement is 100 mm.
Ion balance mode
The ion balance is measured. The measurement
reference distance is 25 mm.
(* An optional ion balance plate is required.)

3. Output state
Set the output state (N.O./N.C.) of judgment output ON/OFF.
There are three judgment outputs:
• HI judgment output (Black wire)
• GO judgment output (Gray wire)
• LO judgment output (White wire)
The judgment output is turned ON/OFF according to the tolerance setting value.
"Changing the Tolerance Values" (page 9)
When Normally Open is set
When Normally Closed is set
*1 "Error Displays and Corrective Actions" (page 20)
*2 When the judgment value (P.V.) is "-----".
Reference
Regardless of the output state setting, the judgment indicator on the sensor
amplifier only matches the judgment output when Normally Open is set.
4. Distance setting
Set the distance correction. When the sensor head cannot be installed at the
reference distance (25 mm for "near" and 100 mm for "far"), you can correct the
measured value by setting the installation distance.
 Distance setting screen
When set to the default setting, [defLt], the following screens are skipped.
When you set this to the user setting, [Usr], the distance setting screen is displayed.
z User setting, [Usr]
