British Standard Tester BT751 ver1.0/MAR.10 Insulation Tester with Voltage Test BT751 is a portable insulation meter designed for electrical installer to perform insulation resistance measurements with test voltage up to 1000VDC, 600V voltage measurements and continuity test of earth conductors, on civil and industrial electrical environments. And other special features are LOCK function, adjustable timer and large LCD backlight display. The LOCK function can perform a continuous insulation measurement to the device under test. Adjustable timer from 2s to 60s permits users to decide the duration of the measurements. Its large LCD display with backlight function enable user to work in weak/dim light • 4 Digits LCD display with maximum 9999 counts reading and symbol • Function keys: ZERO, TEST, LOCKo • Continuity Test • Insulation resistance • Auto discharge Due to our policy of continual product development we reserve the right to amend the specifications of all mentioned products without notice.
