By Renée Francoeur
November 29, 2016 – Do you have trouble clamping your wires in hard-to-reach areas? Suited for electrical work in HVAC applications, the Testo 770 hook-clamp digital multimeter’s hook-off retractable post releases the wires when testing is complete.
The 770 series, available from ITM Instruments, also identifies the testing in-process and automatically selects the correct meter configuration, according to Testo.
The DC voltage resolution is 4.000V/1mV, 40.00V/10mV, 400.0V/100mV, 600V/1V and accuracy is ±(0.8% of mv + 3 Digit).
AC voltage resolution is 4.000V/1mV, 40.00V/10mV, 400.0V/100mV<, 600V/1V and accuracy is ±(1.0% of mv + 3 Digit).
The overvoltage category is CAT IV 600V and CAT III 1000V.
