Setting

Power ON

When the "POWER" button is pressed with the meter off, the meter will be turned on. All display segments are displayed for 1 second after the meter is turned on.

Power OFF

When the "POWER" button is pressed for 3 seconds or more with the meter on, the meter will be turned off. If no buttons are pressed for a set time the meter will automatically turn off. (refer to the operation manual on the SMC website (URL: https://www.smcworld.com) for further details).

To conserve battery life turn the meter off immediately after use.

Auto Power-off

If no buttons are pressed for 5 minutes or more the meter will turn off automatically.

Auto Power-off Extension

When the "POWER" button is pressed for 6 seconds or more with the meter turned off, the auto power-off display will extend to 15 minutes (when the auto power-off extension is activated, all the display segments will flash for 3 seconds).

When the meter is turned off again, the auto power-off extension will be cleared.

Peak / Bottom Value Hold

When the "POWER" button is pressed with the meter turned on, the display will be changed to instantaneous value, peak hold value, bottom hold value and back to instantaneous value, in that order.

Note) Release the "POWER" button after "P" or "b" is displayed so the meter is not turned off.

Peak hold value
The maximum charged potential detected and "P" are displayed.
The maximum charged potential is continuously detected and updated from when the peak hold is started. If a value greater than the displayed charged potential is detected, the display will update to show the new value.

Bottom hold value
The minimum charged potential detected and "b" are displayed.
The minimum charged potential is continuously detected and updated from when the bottom hold is started. If a value less than the displayed charged potential is detected, the display will update to show the new value.

Zero Clear

The displayed value can be adjusted to zero for a measured charged potential if it is in the range of the factory zero setting + 5% F.S. (There may be a slight deviation from the factory setting, due to variations in the sensor itself and the ambient environment where the meter is used.)

When "POWER" and "LIGHT" buttons are pressed simultaneously for 6 seconds or more (with the meter on), the displayed value is reset to zero and the meter will then return to measurement mode. Once the meter is turned off, the offset value for Zero Clear is cleared.

Backlight

When the "LIGHT" button is pressed while the meter is in measurement mode, the backlight will turn on. Pressing the "LIGHT" button again will turn the backlight off.

Battery LOW

When the power from the batteries is running low, "L" will appear on the display. Depending upon how much power is left in the batteries, "L" will be displayed differently.

Display resolution change

The display resolution changes depending upon the measured charged potential value.

<Display example>
± 1.0 kV to ± 20.0 kV

Display resolution: 20.0 kV

0 to ± 0.99 kV

Display resolution: 0.01 kV

Error Indication

When a malfunction or an error occurs, information about the affected part and type of error will be displayed.

Error name	Error display	Error contents	Troubleshooting
Zero Clear error		A charged potential greater than +/- 5 %F.S. of the factory zero setting was present when Zero Clear was performed. *The error display lasts for approx. 1 s and then the meter returns to measurement mode. There may be a slight deviation from the factory setting, due to variations in the sensor itself and the ambient environment where the meter is used.	Return to uncharged condition and perform Zero Clear again.
Sensor error		The sensor is broken.	Stop using immediately and contact the local SMC sales branch.
System error		There is an internal data error.	Turn the meter off and on again. If the error has not cleared, contact the local SMC sales branch.
Measurement error		The value of charged potential being measured is higher than the upper limit for the sensor or the sensor is too close to the measurement target.	Eliminate static electricity until the charge is within the measurable voltage range. Also, check if the sensor is the correct distance from the measurement target.
		The value of charged potential being measured is lower than the bottom limit for the sensor or the sensor is too close to the measurement target.
Cable breakage	-	Correct measurements cannot be made if any of the wires in the cable are broken. Even if the sensor is still, functioning and detects a charged potential the display may not change.	Stop using immediately and contact the local SMC sales branch.

Notes for safe use

• Do not carry or swing the meter by the sensor cable.
• Do not press the setting buttons with sharp pointed objects.
• Do not touch the detecting surface of the sensor directly or with a metal object. Such action can result in damage or loss of specified function and performance.
• When measuring objects with a highly charged potential, there is a risk of electrostatic discharge to the hand of the user holding the sensor. In this situation use the high voltage measuring handle (optional extra) and wear protective rubber gloves. Starting from a safe distance, slowly move the sensor closer to the measurement target. Stop immediately if the display shows "HHH" or "LLL" as the charged potential is out of range.
  This means the charged potential is very high, which can be dangerous. The display will not change if the sensor is moved closer to the charged object.
• Do not place objects and cables other than the measurement target near the detecting port of the sensor. Doing so will cause interference and result in an inaccurate display reading.
• Handle cables carefully so they do not get tangled with the user's equipment, as this can be highly dangerous.
• The measurement distance is 50 mm. Refer to scales shown on the label attached to the sensor.
• The meter is designed to measure static electricity and must not be used for other purposes.
