Clamp Ground Resistant Meter Digital Display Anti Interference Ground Earth Resistance Tester

Feature: 1. MULTIFUNCTIONAL: This instrument panel features a black screen design, with resistance and current displayed on the same screen. Our clamp meter also has functions such as real time clock, data storage, data retrieval, alarm, and automatic shutdown. 2. ANTI INTERFERENCE: The entire machine has a wide measuring range, good resolution, convenient operation, portability, accuracy, reliability, stable performance, and strong anti interference ability. 3. APPLICABLE SCENARIO: Resistance meter is a commonly used and essential instrument for telecommunications, electricity, meteorology, computer rooms, etc. Suitable for measuring the grounding resistance of various telecommunications, electricity, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rod, etc. 4. SUPPORT FOR DATA STORAGE AND TRANSMISSION: The clamp type grounding resistance tester is controlled by a microprocessor and can accurately detect grounding resistance. The meter uses fast filtering technology to minimize interference. Simultaneously storing and uploading data. 5. EASY OPERATION: There are few keys on the tester that you can easily master the meter and make accurate measurement.

Specification: Item Type: Clamp Ground Resistant Meter Mode: ST4800 Battery: 1.5V AA battery x 4 (without battery) Material: ABS Basic Parameters: Function: Grounding resistance test, circuit resistance test, leakage current test Environmental Temperature and Humidity: 23 ℃± 5 ℃, below 75% rh Measurement Method: Mutual inductance method Resistance Resolution: 0.001 Ω Current Resolution: 0.01mA Jaw Size: Approx. 55 x 32mm / 2.17 x 1.26in Clock Function: Yes Ω and A Synchronous Display: Ω and A displayed on the same screen Display Mode: 4 digit LCD display, black screen design LCD Size: Approx. 46 x 36mm / 1.81 x 1.42in Measurement Time: 1 time/second Data Storage: 500 sets, with a "MEM" storage indicator and a flashing "MEM" indicating that the storage is full. Data Lookup: When querying data, the "MR" indicates Overflow Display: When the overflow exceeds the range, the "OL" indicates Interference Test: Automatically identify interference signals, and indicate with the "NOISE" when the interference current is high Alarm Function: Issue an alarm prompt when the measured value exceeds the alarm setting value Battery Voltage: Real time display of battery level Automatic Shutdown: Set to 5, 10, 15, 20 minutes, or OFF. OFF means to cancel the automatic shutdown, and the default is 5 minutes.

How to Use: 1. Press the power button to switch the machine on and off.2. When starting up, the instrument will automatically calibrate. After the startup is completed, it will display "OL Ω" and automatically enter the resistance measurement mode. If the instrument does not start up and calibrate normally, it will display the "Er"  , indicating a startup error. Common reasons for startup errors include not closing the jaws properly, clamping in the guide wire during startup, and so on.3. After reaching the set shutdown time, the device will automatically shut down. Before the automatic shutdown, the instrument panel will flash for 30 seconds, and pressing the power button again will delay the shutdown time.
