Etcr8100b Transformer Core Grounding Current Tester Large Diameter Clamp Ammeter Current Measuring Instrument

1.Technical Specifications: Function: transformer core grounding current test; AC leakage current, current, frequency, line test Power: DC6V alkaline dry battery LR6 1.5V × 4 (not included package) Test method: clamping CT Jaw size: 80mm × 80mm (can be clipped φ80mm line, or 96mm × 4mm flat) Range: AC 0.00mA~30.0A Resolution: AC 0.01mA Accuracy: ±1.5%±3dgt (50Hz / 60Hz, 23°C±2°C, wire in the center) Frequency: 20Hz~200Hz Display mode: LCD: 128 points × 64 points Instrument size: host 170mm × 75mm × 30mm; current clamp 194mm × 145mm × 40mm Weight: host 240g (with battery); current clamp 780g Display field: 44mm × 27mm Electric field interference: about 10mA when the external electric field is close to 100A 10mm Sampling rate: 3 times / sec. Data storage: 100 groups (turn off or replace the battery without losing data) Waveform indication: Yes, the display waveform is automatically amplified and cannot be judged based on the amplitude of this waveform. Number setting: Test points can be numbered, for example: 001 Auto power off: The instrument has five minutes to work without automatically turning off and selecting the function. The default is auto power off mode. Alarm setting: Alarm threshold setting range: 10mA~30.0A Alarm indication: When the measured value exceeds the alarm threshold, the test data flashes. Line voltage: AC 600V or lower line test Overflow display: Overrange overflow function: "OL" symbol display Battery voltage: When the battery voltage drops to 4.8V ± 0.1V, a low battery symbol appears, reminding you to replace the battery. Rated current: 5mA in save mode, up to 20mA Lead length: current clamp lead length is 2 m Working temperature and humidity: -10 ° C ~ 40 ° C; 80% rh or lower Storage temperature and humidity: -10 ° C ~ 60 ° C; 70% rh or lower Dielectric strength: (between screw and housing) AC 2kV / rms For safety: IEC1010-1, IEC1010-2-032, pollution degree 2, CATIII 600V, IEC61326 (EMC standard) Accessories: host: 1; current clamp: 1; RS232 communication line: one; software CD: 1; cloth: 1 Notes:the batteries not included package
