The main characteristics of testers

1.As the single-phase relay tester adopting microcomputer control, therefore there are only 16 touch switches on the panel, that can complete varies of testing functions, change the old-fashioned relay protect tester which must turn off the power switch and toggle switch to convert power supply type, easy to operate. The single-phase relay tester set self-checking and error function, which convenient for inspection and maintenance.

2.The single-phase relay tester set comprehensive self-checking and self-protection function, which can make immediay self-checking after booting, in the process of overload and over-range measuring, the protection circuit will quickly cut off output, and will give a sounding and light alarm to reduce the unnecessary losses due to misuse greatly.

3.The single phase relay tester with high inligence, just press a button, that you can measure all the general electric relay parameters, automatically printing, and allowing you free from the tedious testing operation.

4.The device display screen unit, clearly reflect of operating status will show on the display screen.

5.The printed data will all be displayed in English characters, such as "pull-in voltage", "disconnect voltage", "normally open pull-in time" and so on.
