Probe away the usable range with the included thermocouple is -4 ☏ to 500 ☏ (-20 ☌ to 260 ☌)! With a more heat tolerant probe, the upper limit is much higher.
Or maybe you need to verify that the freezer is sufficiently cold. This is useful for seeing how hot motors, circuit breakers and other devices are running and to make sure they aren’t at risk of thermal overload. The DMM also comes with a “K” type bead thermocouple probe to measure surface temperatures in ☏ or ☌. And it simplifies the process of locating a line break. This is a great way to quickly check whether 110VAC (or higher) electrical wiring and outlets are energized. NCV = A-OK The Non-Contact Voltage feature senses the presence of line voltage without making electrical contact.Īs a tech, one of my favorite (and lamest) one-liners was to implore others not to “lick the red wire.” With the non-contact voltage (NCV) detector – one of the DMM’s feature gems – you won’t have to lick any of the wires: red or otherwise.īy placing the top end of the meter within close proximity of household wiring, an electrical outlet or extension cord, the DMM will sense and indicate the presence of line voltage with a flashing red LED and beeping sound. The TS04 load tests 1.5V and 9V batteries for a much more accurate measurement. Over the years, I’ve encountered many batteries and wall warts that appear just fine with a regular voltmeter, only to collapse to near-zero voltage the instant a load is applied. But this isn’t just a repair tech’s tool any electrician or homeowner will find this unit to be a welcome addition to their arsenal.Īll the standard functions are present and accounted for: voltage, current, resistance, diode check and continuity buzzer. I spent over 22 years of my life as a consumer electronics technician. ToolSmart model TS04 (MSRP $49.98) is a compact, auto-ranging multimeter with all the features you’d expect from a good quality DMM. So c’mon, let’s check these babies out! The Digital Multimeter Using the diode test function to check a semiconductor junction. General Tools & Instruments provided their new ToolSmart line for me to evaluate in this sponsored review.

But they can also send data wirelessly to the free iOS and Android mobile app, opening up a whole new world of awesome that you’re sure to love. They can all be used as stand alone tools. The launch lineup includes a digital multimeter (DMM), laser distance measurer, digital angle finder and a video inspection camera. Smart, convenient and clever: the new ToolSmart tools from General have a lot going for them.
