Function Key (function key)
Power on: Press the "function/on" button once
HOLD function: Press the "function/on" button once
Distance selection: Press and hold "function/on" until "change cm" appears on the display, then press again
"function/on" can select the distance or switch to CPS mode, and other functions can be selected after 2 seconds.
Shutdown: Press 2 times "function/on"
Specific operations:
1) Press 1 "function/on" to turn it on, then remove the probe cover!
2) After booting, the 2cm test distance is displayed by default on the first line of the display.
2cm from the measured object can measure static voltage of 0~+/-16kV, if the surface voltage of the measured object is higher than 16kv or
When the surface is rough, the distance measurement should be selected. If the surface voltage of the object to be measured is lower than 8kv or the surface of the object is flat, the test distance should be 1cm.
When the screen automatically displays "overflow", you need to increase the test distance.
Use the distance benchmark (2cm) to properly control the test distance.
Dist. = 2cm
U = 000 V
To select other measurement distances, the steps are as follows:
Press and hold "function/on" for about 2 seconds, "changedistance" appears on the display, then quickly press the "function/on" button.
Each measurement is replaced by 1 time, and the display order is
2cm => 5cm => 10cm => 20cm => CPS-Mode => 1cm
The selected measurement distance will be displayed on the first line of the screen. Later, the test voltage range for that distance will be displayed on the second line.
The measuring distance is the distance from the probe to the surface of the measured object. The probe is 6.4 mm above the fuselage. The contact should be avoided as much as possible, so the test distance can be measured from the fuselage.
But to reduce 6.4mm.
Each time the machine is turned on, the automatic silent distance is 2cm.
There are two types of measured values: V and KV.
When the measured value exceeds 999V, the unit is automatically converted to KV
The measured values ​​are displayed in the following forms, for example:
578 V------------578 volts
3.85 KV---------3.85 kV
24.0 KV---------2.4 million volts
150 KV----------15 million volts
3) HOLD function key
The HOLD function keeps the measurement results on the display screen.
Press 1 "function/on" to activate the HOLD function, then on the screen
The first line shows "hold" and the second line shows the measured value.
Press 1 "function/on" quickly to turn off the HOLD function, screen
The actual measured value is displayed on the screen.
4) Grounding
When measuring static voltage with EFM022, ground the instrument (through the matching grounding wire), in order to correctly display the voltage and polarity, due to the use of EFM022 housing
Conductive material, so the instrument itself can be grounded without a grounding wire when the tester is grounded.
Testers can wear grounding wrist straps and wear anti-static shoes to ground.
5) Battery
The EFM022 uses a 9V battery. When the battery is lower than 7.6V, the screen displays “LowBatteryâ€. At this time, it is required to replace the battery. If the battery is lower than 7.1V,
The screen will display “auto off†for 2 seconds, then automatically shut down.
Please use Alkaline or NiMH 9V battery!
6) When EFM022 stands by for more than 5 minutes, it automatically shuts down
Product Maintenance
When the "Low Battery" is displayed, the 9V Alkaline or NiMH battery needs to be replaced.
Under normal circumstances, the instrument does not need to be cleared. If the probe is shielded (for example: when the grounding person covers the probe with your hand), or after using it for a long time, the screen cannot
Display U=000, use the instrument side forced clear key to clear (after booting, use a Phillips screwdriver to extend into the small hole on the right side of the instrument to rotate, the initial potential is adjusted to 0V).
Do not touch the probe to prevent dust, paint, liquids, etc. from entering the probe. Use a cotton swab, clean soft rag and alcohol to clean the probe.
The warranty period of the instrument is 12 months. It is caused by wrong operation or human cause. It is not covered by the warranty. Please do not open the instrument case, otherwise the warranty will be lost.
caveat:
1. Please do not open the instrument case, otherwise you will lose the warranty right.
2. This instrument cannot be used in places with explosion hazards.
3. When measuring high potential, the instrument should be grounded and kept at a safe distance from the object being measured.
4, to avoid sparks close to the probe
5. This instrument cannot be used in power plants.
6. The instrument cannot correctly measure AC electromagnetic fields greater than 1 Hz.

CPS022 matching electrode plate tester
The EFM022 electrostatic field tester is equipped with a 75mm x 150mm charging plate (20pF) and a CPS022 high voltage generator to measure the ionizing time of the ion wind.
And ion balance (according to EN61340-5-1., if you need to comply with EN63140-5-1., please use CPM374 flat tester).
Built-in timer measurement (+) 1000Vè (+) 100V and (-) 1000Vè (-) 100V power dissipation time, minimum output value +/- 2V.
Instructions:
1) Remove the 2cm distance bar counterclockwise, then open the probe cover (Figure 1)
2) Place the grounding plate on the EFM022 and tighten it (Fig. 2, Fig. 3)
3) Install the charging plate above the grounding plate (Figure 4, Figure 5)
4) Fix the EFM022 electrostatic field tester on the supporting conductive base, ground the base (Figure 6)
5) Power on and switch to CPS-MODE mode, start measuring
measurement method:
1) The CPS022 high voltage generator has a (-) electrode on the left and a (+) electrode on the right. Press the “Press†button to generate a voltage of 1100V or higher on the electrode.
Touch the electrode to the charging pad on the EFM022
2) When the ion wind blows toward the charging board, the voltage on the charging board starts to drop. When the voltage drops to 1000V, the EFM022 internal timer starts to count.
When the voltage on the charging board drops to 100V, the timing stops. In this way, test (+) 1000V to (+) 100V respectively.
And (-) 1000V down to (-) 100V time required.
3) After the timer stops, after a while, the screen shows the excess voltage (ion balance)
4) Press the “function/on†button again to start a new test.
