1. Features

● Battery powered, the instruments test insulation up to

100000MΩ at 2500V for KEW 3121A, 200000MΩ at 5000V

for KEW 3122A and 200GΩ at 5000V and 400GΩ at 10000V

for KEW 3123A.

● Suited for heavy duty electrical maintenance and servicing of

industrial installations, cables, transformers, generators and

switchgear where high voltage insulation tests are required.

● Dual scales for low an

d hig h ranges whic h change

automatically. Colour coded scales for easy reading plus

LED's that illuminate in matching colour.

● Drip proof construction. The case is sealed with rubber

gaskets to protect internal circuit against rain.

● Hard carrying case furnished as standard accessory. Houses

both instrument and test leads in compact form. Made of

plastic, it is highly water resistant.

● Designe

d for low power consumption. Since the maximum

current consumption is 90mA eight pieces of 1.5V SUM-3（or

equivalent ） permit about 6 hours of continuous operation

even when the instrument is used on maximum load or twice

longer on minimum load.

● Rated output voltage is maintained down to 100MΩ for KEW

3121A, 200MΩ for KEW 3122A and 0.2GΩ/0.4GΩ for KEW

3123A. This permits accurate measurements of

low insulation

resistance.
