Feature: 1. AC and DC leakage current meter, support clamp CT, non‑contact measurement, safe and reliable. 2. Precise winding head design, range is 0mA‑60.0A, high measurement accuracy. 3. Slender jaw design, strong adaptability, fully automatic switching gears, suitable for line testing of 600V and below. 4. Mainly measure automobile DC dark current, leakage current, etc., other AC and DC current, leakage current measurement. 5. Support knob zero adjustment, strong anti‑interference, support data retention, automatic shutdown. Specification: Item Type: Leakage Current Tester Material: ABS Model: ETCR6000B Measurement Function: Automobile DC dark current, leakage current, etc., other AC and DC current, leakage current measurement Power Supply: 1 x 6F22 9V Battery, 100 hours of continuous use (Battery Not Included) Test Method: Clamp-on CT, non-contact measurement Jaw Size: Approx. 16x18mm / 0.6x0.7in 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 Shifting: Fully automatic switching Line Voltage: 600V and below line test 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 Support Functions: Data retention, overflow display, automatic shutdown, battery voltage 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 to Use: Get 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 zeroed, which has strong 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..
