Earth Resistance Tester are two measurement modes: two-pole method and three-pole method. It can also measure the earth voltage. The instrument uses a large liquid crystal digital display with a backlight, which is easy for the user to read. It has data storage function, which can store 100 sets of measurement data, and the data will not be lost when power is lost, which can be convenient for users to make historical data inquiry.

Earth Resistance Tester lead is connected in parallel to the voltage source or load terminals for measurement and the voltage value is displayed on the LCD screen. Earth resistance measurement by Bi-pole method (simple measurements) This method does not use the measurement method of auxiliary grounding rod. The existing grounding electrode with known minimum grounding resistance is used as auxiliary grounding electrode, such as metal buried pipes, common grounding of commercial power supply or building lightning rod as auxiliary grounding electrode.

Earth Resistance Tester resistance of the auxiliary ground rod is too large, and the current cannot flow through the instrument. (3) Calculating earth resistance values The measured value Re is the sum of the earth resistance value re of the auxiliary grounding electrode and the true earth resistance value Rx, so the measured value Re minus the value re is the true earth resistance value Rx: Rx (earth resistance value) = Re (measured value) - re (earth resistance value of the auxiliary grounding electrode).

Earth Resistance Tester rod and C auxiliary grounding rod. The rotary switch is rotated to the 'Tri-pole method' position, and the measurement is started by pressing the 'Measure' key. The 'Measure' key light is lit and flickered. After the measurement is automatically stopped, the buzzer rings and the 'Measure' key light is extinguished.

Earth Resistance Tester Note: Please insert the auxiliary grounding rod into the moist soil as far as possible. If you must insert dry soil, stone or sand, please wet the part inserted by the auxiliary grounding rod with water to keep the soil moist. When measuring on concrete, please level the auxiliary grounding rod, shower water or put wet towels on the auxiliary grounding rod.

Earth Resistance Tester (2)Briefly press the " " or " " key to flip up or down the data. (3)In the read mode, press the 'READ' key to exit the read mode. Data deletion The meter can delete the data in the read mode. Briefly press the 'CLR' key to delete the data at the current position.
Earth Resistance Tester (3)In the AVG measurement mode, the average value of the measurement results is displayed during the measurement process. Backlight Press the ' ' backlight key to turn the backlight on or off. Auto shutdown The meter defaults to turn on the automatic shutdown function. Press and hold the ' ' key and turn the rotary switch to turn on the power to turn off the automatic sleep mode.
