Frequency Selector Switch to eliminate the effect of harmonics. • Three AC current ranges 20mA/200mA/200A. • Rotary switch for easy one finger power-on and range selection.
Large transformer jaws of 68mm diameter makes it possible to clamp on all three or four wires (3 phases) together for leakage current measurement. • True RMS enables an accurate measurement for distorted waveforms. • Measurement from mA up toAC 1000A • Frequency filter switch to eliminate the effect of the harmonics. • 2 way analogue output terminal:AC current detected by transformer jaws is converted to AC and DC voltage. Output cord model 7073 (option) is used for monitoring waveform with an oscilloscope or for connecting to a recorder.
Extra wide transformer jaws are best suited for clamping on all three or four wires (3phases) together for leakage current measurement. • Frequency filter switch to eliminate the effect of harmonics. • Output terminal.
Digital clamp meter with tear drop shaped, medium size transformer jaws specially designed for leakage current measurement. • Frequency filter switch to eliminate the effect of harmonics. • Output terminal for connection to recorders and facility to operate from external power supply permit continuous leakage current monitoring.
THE LEAKAGE CURRENT IS RECORDED BY 3CH INPUT60,000 DATA IS RECORDED 60,000 data is recorded when 1ch is used and when three all channels are used, 20,000 data is recorded for each channel Continuous measurement time About 40 days Data where it doesn’t disappear even if battery is consumed Data doesn’t disappear by using the nonvolatile memory when the battery is consumed and the battery is exchanged. (warranty for 10 years) Battery residual display The battery state is displayed by 4 stages. (When blinking is displayed, it is possible to measure for about one day) The present time, recording intervals, the start of recording, the recording method, the name of monitoring site and the comment can be set by using supplied software
3 channel inputs for the simultaneous recording of Leakage Current, Load Current and Voltage • Power Quality analysis(only on KEW 5020)(Power Quality:Reference voltage, Swell, Dip, Short power Interruptions) Large Capacity for storing 60,000 data points 60,000 data points can be recorded when 1ch is used, and when all the three channels are used, 20,000 data points per channel can be recorded Lowpass Filter will filter out the harmonics(Cutoff Frequency = Approx. 160Hz) LED flickers when the preset current / voltage value is exceeded CALL: Confirmation of recorded data • The following can be displayed: number of recorded data points, (max+ min+ peak) value for each channel complete with time/date information in the Normal recording mode. (Detected values (i.e. when values are outside preset limits ) can be displayed in other recording modes) • RECALL: The last 10 recorded data points including time/date can be recalled on the logger display
Floating voltage can be measured *Floating voltage:phase to phase voltage not grounded *KEW 5020-01:KEW 5020 logger with KEW 8309 (1 pce.) For use with following model 5020
Flexible for various test fields • Can measure AC current up to 3000A • Flexible and light weight by the air core coil used at the sensor part • Measurable conductor size:max Φ150mm • Designed to meet the international safety standardIEC 61010-1 CAT.III 600V Applicable model 5010/5020 (*), 6300, 6305, 6310, 6315
