Applications

For checking the performance of ionizers, locating and measuring electrostatic charge build-up, deciding best location for installing ionizers and testing their efficiency, etc.

The digital numerical value and the bar graph displayed on the LCD indicate the static voltage on the target object. AE-770 is calibrated for the voltage range 0 to ±20kV.

For accurate measurement, make sure to ground AE-770 with its ground wire.

The unit of measurement : kV

If the reading blinks at [±22.0] with a continuous warning sound during the static charge measurement, maximum voltage reading limit has been exceeded.

The measuring distance between AE-770 and the target object needs to be 25mm±0.5mm. This measuring distance can be easily checked by “Focus Rings” beamed from the two red LEDs on the sensor side of AE-770. Position AE-770 where the two red light beams converge as one concentric circle for accurate measurement.

How to activate "standard mode"

Press "POWER" button once and the unit will be set to "static charge measurement mode (standard mode)."

"Automatic ranging digital display"

While in standard mode, the decimal point is automatically set to a right position.

AE-770, designed to be compact and lightweight, making it ideal for periodic verification of ionizers, including those installed on hard-to-reach places like automated machinery or workbenches. AE-770 can be used to measure low voltages up to 200V in the ion balance mode.

Before starting ion balance measurement, install the ion balance plate to the top end having the sensor.

For accurate measurement, make sure to ground AE-770 with its ground wire.

How to activate "standard mode" 

Turn AE-770 on by pressing POWER button and then press ION BALANCE button.

The ion balance plate is kept on the bottom end.

The ion balance plate can be kept attached to the bottom end when not in use.

The upper left section displays bar graph inblueto indicate negative polarity voltage.

The upper right section displays bar graph inredto indicate positive polarity voltage.

The lower section display shows reader-friendly numerical values, voltage measurement unit, and functions in use.

The battery condition icon changes in 4 stages as the battery level decreases. Replace the battery when display shows the battery to be empty.

The life of the included 9V, 6F22 Manganese battery : Approx. 30hours.

"LED lighting function" to read measurement values in the dark.

Switch on and off the LCD backlight by the POWER button.

• Turn off the LED: Keep POWER pressed for less than 1 sec or 3-5 sec.
• When turned on to the standard mode … 1 beep

AE-770 indicates its operating status by beep sound.

Beep sound represents the following conditions:

• When turned on w/o auto power off function … 3 beeps
• Auto power off indication … 5 beeps
• Over range … 1 long beep
• Turn on the LED : Keep POWER pressed for 1-3 secs or more than 5 secs.
