The testo 770 ammeter is available in 3 versions. The exact differences are given in a comparison table in the PDF product description under Downloads.
The testo 770-2 current pincers enormously facilitate work in narrow measuring points such as control cabinets. The movable leg of the current measurement pincers can be fully retracted into the device. This means that closely spaced conductors such as cables can be gripped accurately and checked for faults.
It also enables measurement of the start-up current in electric motors and ionisation current testing in the µA range. The supplied temperature adapter for thermocouple sensors can be used to measure temperatures in addition to electrical parameters (suitable thermocouple sensor type K can be ordered separately).
The current pincers automatically identify and select AC/DC and also select other electrical measurement variables such as resistance, continuity, diode and capacity independently. This makes operation easier and safer than ever. Your measurement values are shown clearly and distinctly on the two-line display.
