ETCR6000 AC/DC Clamp Leaker Leakage Current Tester 0mA‑60.0A 99 Units Digital Clamp Meter Item Type: Leakage Current Tester Material: ABS Model: ETCR6000 Measurement Function: AC and DC leakage current, current measurement Working Power Supply: 6F22 9Vx1(Not Included) Test Method: Clamp-on CT, non-asurement Jaw Size: Φ7mm Range: 0mA~60.0A AC/DC Resolution: 1mA AC/DC Accuracy: ±2%rdg±5dgt (23℃±5℃, below 75%rh) Display Mode: 4-digit LCD display Sampling Rate: 2 times/sec Frequency Response: AC 45Hz~400Hz Polarity Indication: Automatic recognition when DC current is detected, display "-" sign. Wire Position: The wire to be detected is at the center of the jaws Shift: Fully automatic switching USB Interface: With a USB interface, the stored data can be uploaded to the computer, saved and printed. Communication Parameters: Baud rate 9600, data bit 8, stop bit 1, parity bit NONE Working Current: 10mA Working Temperature and Humidity: -10℃~50℃; below 80%RH Limit Temperature Error: -10℃~0℃ and 40℃~50℃, the maximum error increases by 2%rdg Storage Temperature and Humidity: -10℃~60℃; below 70%RH Insulation strength: AC 3700V/rms (between core and box) How e: Take the product, open the back cover with a tool, install the battery, and the user can adjust the measurement range, and then you can use the measurement. The right knob is used for zero adjustment, which has enhanced anti-interference and better calibration to zero. HOLD is the data holding key. It is very convenient to measure by simply putting the wire into the jaws.
