Profile:
The working principle is that the DC/AC converter in the machine changes the DC into AC low frequency constant current, and the circuit is formed by the auxiliary ground pole C and the measured object E. The AC voltage drop is generated on the measured object, which is sent to the AC amplifier through the auxiliary ground pole P for amplification, and then sent to the watch head for display through the detection. With the power switch, three different limits can be obtained: 0-2Ω, 0-20Ω, 0-200Ω, 0-2000Ω.
Features:
1, the application of DC/AC conversion technology, set three-end button, four-end button as one, the use of power can be AC, DC dual use.
2, the use of phase-locked synchronous tracking detection mode, and switched capacitor filter, so that anti-interference ability is very strong.
3, abandon the traditional manual hand-operated power generation mode, do not need human work.
4, no manual adjustment balance, clear panel touch key operation, LCD digital display makes the measurement is very convenient and rapid, eliminating the visual error of the pointer instrument.
5, the allowed auxiliary grounding resistance resistance value is very large, better ensure the measurement accuracy, high resolution.
