Safe Operating Guide
- Inspect the multimeter and test leads for any visible damage before proceeding.
- Insert the black test lead into the COM terminal and the red lead into the V/Ω/Hz terminal.
- Turn the rotary dial to the desired measurement function (e.g., Voltage, Continuity, or Capacitance).
- For standard checks, allow the auto-ranging function to select the appropriate range, or press the RANGE button for manual selection.
- Apply the probes to the circuit under test and read the result on the backlit LCD display.
Field Reviews from UK Pros
Absolutely superb electrician multimeter. The True RMS accuracy is spot on when checking variable frequency drives at work. Feels incredibly robust in the hand and the continuity buzzer is loud enough to hear on a busy site.
Bought this after my old generic meter died. The auto ranging on this is incredibly fast. Next day delivery was exactly as promised. Highly recommend for any serious DIYer doing domestic rewires.
Great piece of kit and excellent value. The multimeter capacitor tester function works perfectly for my HVAC repairs. Dropped one star just because I wish it came with a hard carry case instead of just the rubber holster, but the unit itself is faultless.
I was looking for a reliable test electric meter that didn't cost a fortune. The safety ratings on this gave me peace of mind. The backlit screen is brilliant when working in dark loft spaces.
I usually buy premium brands, but I needed a backup. Honestly, this holds its own against my £200 meter. The diode tester on the multimeter is very accurate, and the silicone leads feel very high quality.
Very solid multimeter multi tester. It's a bit heavier than my last one, which takes getting used to, but it feels like it could survive a drop down the stairs. The continuity test is instant, no annoying delay.
