Product Introduction:
Easy to operate(Remote control testing)By using the remote control testing function, the test can be automatically performed by simply connecting the test line to the terminal. The initial display is the circuit voltage,1Start testing the action time or sensitivity current to automatically determine the voltage in seconds. Due to the ability to automatically distinguish100Vand200VThe measurement of circuit voltage does not require manual switching of different voltage action times. ×1/2When measuring the range, conduct a rated non operating current test. ×1、 ×5When measuring range, the action time can be testedSensitivity current test. Automatically increase the test current, indicating the current value at the time of trippingAutomatically detect contact voltage. When using a grounding wire for testing, in order to prevent electric shock caused by poor grounding, the voltage of the grounding electrode or protective conductor will be automatically detected when the test current flows. Once it reachesAC50VStop testing and issue a warning.

Fluke1625Grounding resistance tester
Fluke 1623and1625It is an excellent grounding resistance tester that can measure all four types of grounding resistance. especiallyFluke 1623and1625The measurement of grounding resistance can be completed using only one current clamp - no auxiliary pole method. This method does not require the use of auxiliary grounding electrodes or the disconnection of grounding rods.
test mode
3Jihe4 Polar potential drop method - a standard grounding resistance testing method using two grounding electrodes.
Selection method test - without disconnecting the grounding rod, the grounding resistance can be measured using a combination of grounding electrode and current clamp.
Non auxiliary pole method - a highly innovative testing solution that does not require the use of grounding electrodes and can measure the resistance of the grounding loop using only current clamps.
Fluke 1625It also provides the following advanced features
Automatic frequency control(AFC)Automatically identify interference and select measurement frequency to minimize the impact of interference and provide more accurate grounding resistance values.
R*Measurement - Calculation in55 HzThe grounding impedance below more accurately reflects the true grounding resistance when a grounding fault occurs.
Adjustable limit value - can quickly check test results.
