MS5209 Grounding Resistance Tester Details

Product Description:
Features:
·The latest designed circuit enables this tester to operate with induction of the lowest amount of ground voltage and ground resistance from the auxiliary grounding rod
·The auxiliary grounding resistance and wire connection can be self checked by pressing the "BATT. CHECK" button. The "OK" light is on, indicating that the tester is ready to perform precise ground resistance measurement.
·Low power consumption, maximum value of 12V/100mA
·Pressing the switch makes the operation of this tester simple and easy
·The grounding resistance value can be directly read from the dial
·Simply press the "SIMPLIFIED MEAS" button to easily simplify the measurement method. For terminals P and C, there is no need to use short-circuit wires. Simply press the "SIMPLIFIED MEAS" button to short-circuit them internally
·Easy battery replacement without opening the carrying case
·The hard plastic carrying case can accommodate all accessories, making it easy to carry
