Product Introduction
With the Charge Plate Kit becomes from the EFM 022 a charge plate monitor, to the supervision of air ionization appliances after the EN 100015 as well as EOS/ESD S.3.1
The charge electrode corresponds to the norms from the capacity (20pF), but not from the
dimensions . For directly measure conform to the norms, use our CPM 374. With the CPS 022, however reproducible measurements can be performed.
It becomes the decay-time from + 1.000V … . + 100V or.- 1.000V....- 100V with an integrated
start - stop - timer. The charge takes place over an external HV- Converter. In the CPS-Mode voltages up to max. 2kV will be displayed.
Parts of delivery:
· HV - Converter
· 3 pce. rechargeable 9V Battery
· Battery - Charger · CPS - Socket
· Plate condenser
· Grounding cables 1,5m and 1m · Crocodile Clip
· Transportation suitcases
CPS 022 Kit Operation Instruction
The EFM 022 from software version V4.0 is prepared for using the Charge – Plate - Monitor. Some older versions can be updated by the manufacturer
Preparation of the unit
· Bring the CPS – Socket in position and put in the EFM 022 vertically · Screw the ground plate on the EFM 022
· Press the field-plate onto the bolts in touch to the ground-plate
· Connect ground between the HV - Converter and the CPS – Socket · Connect the CPS – Socket to ground
· Switch on the EFM 022 and wait until „Dist.= 2cm" and a measure value is displayed
· Press and hold the „function/on“-key (approximately 2 sec.) until „change cm“ will appear in the second line. The pre-selected distance in cm will be displayed in the first line. Press the „function/on“-key shortly to change the measurement distance, until “CPS - Mode” is
displayed. With each short press of the „function/on“-key the proposed distance will appear as follows: 5cm => 10cm => 20cm => CPS - Mode
· please wait (do not press the „function/on“- key) until the cps - mode will appear in the
The unit is now ready to work as charge plate
CPS - Measurement
· Through pressing of the button at the HV - Converter, a high voltage > ±1100V becomes at the
two contacts of the appliance generates
· Through touching of the upper field plate with the corresponding contact( + or - )the
· HV-Converter is loaded the plate. ( see picture )
· The unit recognizes the correct polarity automatically and now is ready for the measurement
· The internal timer is started with achievement of ± 1000V on the field plate
· The internal timer now counts upward in 0, 1sec steps , as far as on the field plate ± 100V is
· In the upper line now it will displayed the pos. or neg. discharge time
· In the lower line, the current voltage is shown on the field plate, until the “function/on" button is pressed. Then, the voltage measured at this time on the upper plate is shown as offset
· Pressing the function/on“ – key again will reset the display, and it can be started a new measurement
Maintenance
Do not touch the modulator system to prevent mechanical damages.
Avoid any insulating build up as e.g. dust, paint or varnish dust, condensed water or similar influence. If it is necessary the modulator system may be cleaned with alcohol and a soft fuzzy-free cloth.
Replace 9V - battery
The 9V block-battery has to be replaced when “Low Battery” appears at the display.
Please switch the unit off before open the battery compartment. Take out the battery and remove the connector clip. Put the connector clip on the new battery and put it into the compartment. Close the compartment.
Zero Adjust
A zero adjustment is normally not needed. In case, that the unit does not indicate U=00X while the modulator system is shielded (e.g. grounded person covers the modulator system with one hand), use the trimmer (6) for zero adjustment. The last digit can be ignored as the caused measurement failure is much lower than the specified tolerance.
Guaranty Performance
By correct operation and in accordance to the instruction manual we allow a 24 month warranty . The warranty does not include: The Battery / NiMH – accu, damages by electrical discharge,
incorrect grounding and mechanical damage of the Field Meter.
If you open the unit, you will lose the Guaranty !
Calibration
It is advisable to recalibrate the Electro-Fieldmeter once a year.
