MASTECH

Features

Broad Range of Testing Voltage :

-

Testing voltages with broad range can be generated (from 250 V to 5 KV).

-

Testing voltage can be preset as 250 V, 500 V, 1 KV, 2.5 KV, or 5 KV, or as a voltage increasing or decreasing in steps of 25 V or 100 V.

Insulation Diagnosis :

-

PI and DAR can be automatically calculated and displayed

-

Step-voltage measurements and temperature compensation is carried out.

Large Storage Memory :

-

Up to 100 manually tested data and 10 groups of log-test data can be saved.

-

Test data can be read on LCD, or uploaded to PC

Clear Display :

-

Large-screen display. Test result is displayed with indication through a graduation bar.

-

LCD screen is backlit, which is suitable for viewing when it is dark.

PC Communication :

-

The meter is equipped with a USB interface, through which the saved test data can be uploaded to a PC for further table/figure making and report generating with convenience.

Robust and Durable :

-

With a compact structure, the tester is robust, durable and portable.

Powered by Batteries :

-

With a selection switch, the tester can be powered by an alkaline battery.

-

This tester can be continuously operated for a longer period of time than similar meters if a LR14 alkaline battery is used.
