With all the sophistication present in the Armada Technologies PRO90 Automatic Clamp Multimeter, you might expect the PRO90 to be complicated and full of switches. That's not the case. The Armada Technologies PRO90 is fully automatic and hassle free. The single button is used to turn the Armada Technologies PRO90 on and hold readings. That's it. It even automatically backlights when you're working in the dark, the screen automatically lights. Troubleshooting has never been so easy. Amps, volts, and ohms are all automatically read and the range is automatically set by the Armada PRO90. The Armada-Technologies PRO90 is so automatic it even lights up automatically when darkness sets in. Because the Armada-Tech PRO90 is automatically ranged, there are no fuses to blow.

Just connect it to the circuit to be tested and the Pro90 automatically:

1. Looks for voltage from 1.3 to 600 volts AC or to 1000 volts DC. If it sees it, it measures it including automatically setting the correct range and determining AC or DC. All automatcally.

2. If the Pro90 does not detect any voltages, it automatically switches to resistance or ohm measurement, again auto-ranging.

The clamp is used for measuring AC currents from .9 to 400 amps.
