This instrument is controlled by intelligent microcontroller chip, with high accuracy and high reliability; it can be used to measure grounding resistance of various power facilities wiring, electrical equipment, fulmination protection equipment and other grounding devices, and it can also measure ground voltage. (Note: This instrument is not suitable for harsh outdoor environmental conditions, such as raining, lightning, etc.)
Functions
Backlight and battery detection function.
Data holding.
It can be used for precise three-wire measurement or simple two-wire measurement.
When measuring ground resistance, if C or E end of test lead is not in good contact, "---- ohm" warning appears on LCD.
"OL" stands for over range. 6.Double insulation or reinforced insulation safety structure
This instrument is only suitable for single-phase 230V /50Hz (with power supply voltage range
Wiring check: whether three LED indicators are correct, if two green indicators P-E and P-N are on, and red indicator is not on, then it is correct: the test can only be triggered if the wiring is correct
Phase angle selection: you can choose to start the test from positive (0 degree) or from half cycle negative (180 degree)
a??OL" is displayed for over range: when the test trip action time exceeds high test time, the LCD will display "OL mS"
Automatic data holding: After test is completed, the displayed measurement results are held for a certain period of time
AUTO RAMP test: The AUTO RAMP test can test tripping current and time simultaneously
Shutdown alarm function: After 3 minutes of operation, the instrument will let out a shutdown beep alarm
Power supply: Directly supplied by circuit under test (power supply 230V / 50Hz)
Bluetooth connection: the mobile phone can directly control the multimeter.
More applications of measurement data: data logging, data graphing, data exchange, data storage and export, threshold alarm.
Multimeter collaboration: The application can connect four Bluetooth multimeters and monitor the measurement data of the four multimeters in real time at the same time.
Intelligent calculation function: use the data in the multimeter to quickly calculate the power and other mathematical formulas.
Remote assistance: real-time remote screen synchronization, convenient communication, real-time monitoring without distance and ultra-long distance.
