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 in places such as rain and corrosive gases.
The instrument should avoid severe vibration.
Maintenance, care and adjustment of the instrument should be performed by professionals.
After the test is completed, be sure to wait until the discharge alarm stops and then turn off the power and remove the test wire.
When measuring the no-load voltage regulating transformer, be sure to wait for the discharge indication alarm sound to stop before switching gears.
It is forbidden to move the test clamp and power supply line during the test process
Second functional characteristics
The whole machine is controlled by a high-speed single-chip microcomputer, which has a high degree of automation and is easy to operate.
The instrument adopts a new power supply technology with multiple current ranges and a wide measurement range, which can be automatically selected according to the load
The selected current is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
The perfect protection function can reliably protect the impact of back electromotive force on the instrument and its performance is more reliable.
It has an audible discharge alarm and clear discharge indication to reduce misoperation.
The response speed is fast and the on-load tap changer can be directly converted in the measurement state. The instrument automatically refreshes the data.
Intelligent power management technology instruments always work in the minimum power state, effectively reducing the internal heat of the instrument and saving energy.
