Operation

Warning
The meter must be securely grounded during measuring, and the holding position not close to the sensor so to avoid the risk of electric shock.

• Before use, the meter must be grounded. Please choose one of the following two methods to ground the meter:
  1. The first method is connecting the meter’s ground socket with one end of the grounding wire of accessory and connecting to the earth end of the building with another end of the grounding wire, or connecting to the electrical socket for earthing, or clamping the earth end with a crocodile clip.
  2. The second method is the operator wears the anti-static wrist strap and connects to the earth end of the building with another end of the anti-static wrist strap. Note that the anti-static wrist strap is not an accessory and should be prepared by yourself.
• During the measuring for static voltage, please fasten ceramic spacers on the fix-threads beside the sensor. Keep the sensor from the area under test for 1 inch (2.54 cm).
• Click the Power button.
• Make sure the meter is grounded before operating.
• Aim the sensor point to the area under test, keeping your fingers away from the area under test as possible.
• Read the value (static voltage value) on the LCD.
• As completing a measurement, click the button to lock the reading permanently to hold the reading on the LCD for a long time; click the button again to unlock the reading.
• Click the button to continuously update the maximum measuring value on the LCD to keep the +peak value (max. value), and click the button again to cancel.
• Click the button to continuously update the minimum measuring value on the LCD to keep the -peak value (min. value), and click the button again to cancel.

Disable Auto Power Off Mode
The meter will automatically power off after powering on for about 15 minutes. The LCD displays symbol at the mode. If to disable the function, press and hold the button for more than 2 seconds.

Zeroing

• Prior to measuring the static voltage, click the button for more than 2 seconds to clear the reading if an old reading survived on the LCD. (Note: Set the static voltage of the surrounding environment to be 0, if not, the measuring may be biased.)

Manual record mode

• At measuring mode, click button to record the present reading, the records can be logged up to 99.

Display logs mode

• At measuring mode, click button to display the readings of logged data while MEM symbol appears on the LCD. Click button again to quit the mode. Click button or button to select the number of logs.

Backlight Mode

• During measuring, click the button to turn on the backlight of the LCD for 15 seconds and then turn off automatically.

Setting mode
