Product Introduction :
The ZX2571 Ground Resistance Tester is a commonly used instrument
for inspecting and measuring grounding resistance. It features an
LCD gray-white screen with backlight display and microprocessor
technology, meeting the requirements for two-wire and three-wire
resistance testing. It is suitable for applications in
telecommunications, electric power, meteorology, server rooms, oil
fields, power distribution lines, transmission line towers, gas
stations, factory grounding systems, lightning rods, and more.
The instrument is characterized by high accuracy, speed,
simplicity, and reliability. Controlled by a microprocessor, it
automatically detects interface connection status, ground network
interference voltage, interference frequency, and supports testing
of auxiliary grounding electrode resistance. It can store up to 500
sets of data.
Measurement ranges:
- Resistance: 0.01Ω to 3000Ω
- Ground Voltage: 0.01V to 600.0V.
Performance Features :
1. Equipped with an LCD gray-white backlit display and
microprocessor technology, it fulfills the requirements for both
two-wire and three-wire resistance testing.
2. Controlled by a microprocessor, the instrument automatically
detects interface connection status, ground network interference
voltage and frequency, and supports auxiliary grounding electrode
resistance testing.
3. Capable of storing 500 sets of data. Measurement ranges:
- Resistance: 0.01Ω to 3000Ω
- Ground Voltage: 0.01V to 600.0V
4. Delivers precise, rapid, straightforward, and stable/reliable
testing performance.
(Note: Maintains consistency with previous translations in
technical terms like "ground resistance tester," "microprocessor,"
and formatting styles for ranges. Structural parallelism is
prioritized for clarity, and key specifications are highlighted to
align with technical documentation standards.)
