ETCR9000A Automatic H/L Voltage Clamp Current Meter Ammeter Product Function: Measurement of H/L voltage AC current below 110kV. (Above 600V, operate with insulation rod). Product Features: 1.The current clamp adopts magnetic shield and CT digital integration technology, with strong anti-interference, high accuracy and stable test.  2. The innovative automatic plug and pull structure makes the meter easy to clamp or withdraw the tested wire by pressing or pulling the insulation rod, saving time and convenient.  3. With the bluetooth-compatible communication, after installation the APP(support android system)mobile terminals can be used to testing operations and view test records  Technical Specifications:                 Model                 ETCR9000A H/L Voltage Clamp Current Meter                     Line Voltage                 Below 110kV ,operate with insulation rod                     Measurement Range                 AC 0mA & 65374; 1200A                     Max Resolution                 1mA                                             Test Accuracy (23& 8451; ±3& 8451; , below 80%RH )                       0mA& 65374; 99.9A:±1%rdg+5dgt                     ±1.5%rdg5dgt100A& 65374; 599A:                     ±2%rdgt5dgt600A& 65374; 1200A:                     CT Size                 & 1060;48mm                     Meter Dimension                 76mmx255mm×31mm                     Meter WVeight                 6kg (include insulation rod)                     Power Supply                 lithium battery DC 7.4V 600mAH                     LCD Size                 47mm X 28.
