final test results are displayed numerically. The instrument has
accurate measurement and stable performance, and meets the
requirements of on-site high-voltage switch maintenance and
high-voltage switch factory loop resistance test in power and power
supply departments.
2.Function
The instrument is suitable for high-precision measurement of
high-voltage switch contact resistance (loop resistance), and is also
suitable for other applications requiring high current and
micro-resistance measurement.
3.Features
1. Large current: Using the latest power technology, it can
continuously output large current for a long time, overcomes the
shortcomings of the pulsed power supply instantaneous current,
can effectively penetrate the switch contact oxide film, and obtain
good test results.
2. Strong anti-interference ability: Under severe interference
conditions, the last bit of the LCD screen can be stable within ±1
word range, the reading is stable and the repeatability is good.
3. Long service life: All high-precision resistors are used to
