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.
