AL605 Double Clamp Ground Resistance Tester Multifunction
Performance standards:
DL/T845.2-2004
Features:
1, double clamp / four-wire measurement to pile double: for any ground sites, multi-point or single point grounding, the test can be normal.
2, anti-interference capability: Since the high frequency current, the mains filter in 50HZ, 100HZ other harmonic interference current.
3, wide measurement range, high resolution, automatic range switching.
4, large jaw design: jaw size 40 * 40mm (standard).
5, high-capacity data storage: can store 200 groups of measurement data.
6,0-255 minute timer automatic shutdown, intelligent automatic charging, the battery can effectively avoid waste or failure.
7, the entire Chinese operations, through RS-232 or USB interface with a computer connected.
8, simple, single operation.
