1.Introduction: ETCR068A clamp-type leakage current sensor for AC leakage current, current, high harmonic current, phase, power, power, power factor and other detection. Range: 0.0A~2000A, jaw size is Φ68mm. Current clamp uses a special core, strong anti-interference ability, to ensure the accuracy and stability of the measurement; the use of clamp structure, without disconnecting the measured line, to take non-contact measurement methods, safe and simple operation, you can connect the phase detection analyzer , industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high precision multi-degree digital meters, etc. 2.Technical Specifications:       * Function: AC current measurement        * CT size: Φ68mm        * Range: AC 0.0A& 65374;2000A        * Resolution: 0.1A        * Accuracy: ±2.0%FS(50Hz/60Hz; 23& 8451;±2& 8451;)        * Linearity: ≤1.0%        * Phase error: ≤3°(50Hz/60Hz& 65307;23& 8451;±2& 8451;)        * Reference load: RL& 65306; 0& 65374;200mA≤2kΩ& 65307;0.2A& 65374;2A≤200Ω& 65307;2A& 65374;20A≤20Ω& 65307;20A& 65374;200A≤2Ω& 65307;200A& 65374;2000A≤0.2Ω        * Standard turn ratio: 2400:1 (deuterium ratio can be customized upon request)        * Output method: Current sensing output        * Output interface: 4.0mm double banana plug        * Output line: 2-core shielded cable, length 2m        * Detection method: Clamp CT        * Tested current frequency: 45Hz& 65374;60Hz        * Frequency characteristics: 10Hz to 100kHz        * Electric field interference: about 0.3A when the external electric field 100A approaches 10mm        * Wire position: The tested wire is in the center of the jaws        * Line voltage: Test for lines below AC 600V        * Working environment; -20°C& 65374;50°C; 80%Rh or less        * Storage environment; -10°C& 65374;60°C; 70%Rh or less        * Insulation strength: AC3700V/rms (between core and shell)        * Suitable for safety regulations: IEC1010-1, IEC1010-2-032, Pollution Degree 2, CAT III (600V)        * Weight: 530g        * Appearance size:L x W x H: 185mm×115mm×43mm
