The testo 760-3 has an AC/DC voltage measuring range of 1000 V, TRMS, duty cycle, low pass filter, and temperature measuring. Testo’s exclusive auto-test setup enables the user to simply turn on the unit, connect the leads, and begin measuring. The testo 760 Digital Multimeter detects the lead connection and prevents switching from V to A or A to V if leads are not in proper socket. This prevents accidentally blowing the meter’s fuse because of incorrect connections.
