Baoding Huazheng Electric Manufacturing Co

1. Safety measures
Be sure to read this manual carefully before using this instrument.
The operator of the instrument should have common sense in the use of general electrical equipment or instruments.
This instrument can be used indoors and outdoors, but it should be used away from rain, corrosive gas and other places.
The instrument should avoid severe vibration.
The maintenance, care and adjustment of the instrument should be carried out by professionals.
After the test, be sure to wait until the discharge alarm stops, then turn off the power and remove the test wire.
When measuring the no-load voltage regulating transformer, be sure to wait until the discharge indication alarm sound stops before switching gears.
. During the test process, it is forbidden to move the test clamp and power supply line
2. Functional characteristics
The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and easy operation.
The instrument adopts new power supply technology, with multiple current ranges and wide measurement range. It can automatically select the current according to the load. It is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
It has perfect protection function, can reliably protect the impact of back electromotive force on the instrument, and has more reliable performance.
. It has an audible discharge alarm and clear discharge instructions to reduce misoperation.
. The response speed is fast, the on-load tap-changer can be directly converted in the measurement state, and the instrument automatically refreshes the data.
, Intelligent power management technology, the instrument always works in the minimum power state, effectively reducing the internal heat of the instrument and saving energy.
