Huazheng HZRC-2100C Ground Resistance Clamp Meter
Huazheng HZRC-2100C Ground Resistance Clamp Meter
The earth resistance meter is a resistance measuring device used in power, postal, railway, communication, mining and other departments to measure the grounding resistance of various devices and measure the resistance value of low resistance conductors.
This earth resistance test instrument was designed by technical department of Huazheng Electric Manufacturing (Baoding) Co., Ltd.. Its performance is mainly reflected in:
Breakthrough in Startup Speed: Eliminates long self-test waiting time at boot; the instrument enters the test mode immediately upon power-on.
Intelligent Relay Self-Test: Breakthrough relay self-test mode utilizing advanced processing algorithms and digital integration technology – fully intelligent.
Lightweight Design: Overcomes the weight issues of older products, making it more suitable for handheld devices.
New Design: Panel operation with 6 buttons for enhanced performance.
Audible and Visual Alarm: Added sound and light alarm – "beep-beep--beep--" alarm tone.
Interference Signal Indicator: Added recognition indicator for interference signals.
Enhanced Anti-Interference: Improved anti-jamming capability and test stability.
Data Storage: Stores up to 99 units of data.
Low Power Consumption: Maximum operating current does not exceed 50 mA.
