Feature: 1. The gear is automatically shifted throughout the whole process, which is convenient for measurement. The test method is a clamp‑on CT non‑contact measurement method. 2. The precise winding head demonstrates high precise, with an accuracy of ±2%rdg±5dgt, which makes the measurement more accurate. 3. Slender jaws, jaw size up to Φ7mm, adapt to enhanced and higher resolution. 4. The knob is set to zero, and the anti‑interference is enhanced. It supports data retention, overflow display, automatic shutdown, battery voltage. 5. Milliampere leakage meter, can measure AC leakage current, DC leakage current, accuracy 1mA, range 60A. Specification: 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-contact measurement 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 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: 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.. Package List: 1 x AC/DC Leakage Current Meter( Battery not Included)1 x CD1 x USB Data Cable1 x Manual 1 x Bag
