Current & voltage measurements covered by test families

The three devices that make up the Testo 770 range are clamp meters, ideally suited for current measurement in switching cabinets.

A unique mechanism which retracts one of the two pincer arms ensures that cables, even in constrained cabinets, can still be easily grabbed.

Similarly innovative are the three Testo 760 automatic multimeters that boast function keys in the place of dials, to provide easier operation.

They also feature automatically detected measurement parameters that make it impossible for the user to enter incorrect settings. 

Of the remaining three new families, there are the two Testo 755 voltage testers, which are first of their kind to be capable of measuring both voltage and current. Next are the three models of the 750 range that incorporate novel all-round LED displays, permitting the results to be seen from any angle.

Finally the Testo 745 is a non-contact voltage tester with a range of up to 1,000 V, with both sound and visual voltage warnings, plus a filter for high-frequency interference signals.
