Complete Electrical Test Kit

The MM320KIT bundles a manual-ranging digital multimeter, a non-contact voltage tester with flashlight, a voltage tester and a GFCI receptacle tester in a padded carrying case with batteries included. It is built for electricians, technicians and serious DIYers who need multiple test functions in one portable package.

Simple Setup With Common Pitfalls

Each instrument powers on with its own switch and the multimeter uses a rotary selector for function and range. The non-contact tester activates its flashlight independently of voltage detection. Users often forget to set the multimeter to the correct range before measuring, which can blow the internal 10A fuse, and they sometimes test live circuits without first verifying the tester on a known source.

Verify Your Requirements First

Confirm that the circuits you will test fall within 600V AC/DC for the multimeter, 12–1000V AC for the non-contact tester and 28–240V AC or 32–330V DC for the voltage tester. The receptacle tester identifies common wiring faults in standard and GFCI outlets but does not measure voltage or current. Ensure you have access to the test points and that the kit’s 1.56-pound weight and 12.4 x 7.91 x 2.24-inch case fit your tool storage.

Questions about this item

How do I verify the MM320 multimeter is reading correctly after setup?

Select a known voltage source within the 600V AC/DC range, measure it with the multimeter, and confirm the displayed value matches the expected reading. The meter also tests batteries, diodes, and continuity for additional functional checks.

What items are included in the MM320KIT and what must I supply?

The kit includes the MM320 Digital Multimeter, NCVT-3P Non-Contact Voltage Tester with flashlight, ET45 Voltage Tester, RT210 GFCI Receptacle Tester, a padded storage pouch, and all required batteries. No additional components are needed for the stated functions.

Which voltage tester in the kit covers 12V to 1000V AC detection?

The NCVT-3P Non-Contact Voltage Tester provides dual-range detection from 12 to 1000V AC and 70 to 1000V AC, plus a built-in flashlight. The ET45 covers 28V to 240V AC and 32V to 330V DC with a test lead holder for tamper-resistant outlets.
