Amprobe ACDC-54NAV TRMS ACDC Clamp-on Power Meter 1000A

This may be the 7th multimeter I have had in the past 40 years and it is the best, and it includes power monitoring functions and inrush current measurement and temperature.

I am a commercial Plumber and this tool has been very helpful in setting up and diagnosing rooftop HVAC units

I have been using this amprobe clamp meter for a while and would not concider any other. The features of this meter are easy to use and easy to read. the temp probe addition makes it a great all in one meter.

Strengths:? All-in-one Multimeter, Current Clamp, and Thermocouple Temperature Probe.? Extremely rugged construction that will withstand harsh environments.? Almost perfect one-handed operation.? Good set of included accessories.? Non-Contact Voltage feature actually works.? Built-In LED Flashlight.Weaknesses:? Menu system can be confusing. Reading the manual is REQUIRED.? Option rotary switch is a bit stiff for one-handed operation.The ACDC-54NAV is my favorite meter for the job site where AC/DC testing, verification, and troubleshooting are required. This meter is near perfect for the electrician/engineer that regularly works with residential or commercial HVAC, AC Hydraulics, or DC Telco. I regularly fly to job sites across the country and need a meter that's small and tough enough to pack in my checked luggage without worrying about it getting broken. The ACDC-54NAV is perfect for this.One feature I did not like on the low end Amprobe meters, a non-contact voltage detection called VoltSense, actually works flawlessly on the ACDC-54NAV. I was able to reliably confirm the presense of an AC voltage on wall outlets, power cords, appliances, power supplies, motors, and just about anything else electrical with an AC voltage. DC voltages can also be detected by flicking the clamp past voltage source which flashes the VoltSense LED. This is a great feature for checking for an energized circuit without having to pull out and attach test probes. VoltSense does not detect voltages in walls or at distances of more than an inch from the voltage source.The ACDC-54NAV is one of the best instruments I have used for the work I do and is now my favorite job site tester when I travel. It has all the features I need and has taken a lot of abuse and isn?t obscenely expensive. I highly recommend the ACDC-54NAV for the electrician or electrical engineer that needs to test and verify AC/DC power equipment in a commercial environment.
