  • HVAC techs
Style: Clamp
Overall this is a good meter. I am a new residential HVAC service tech and it can handle most our applications. Can be used to measure amperage draw, voltage, temperature splits, micro amp readings, capacitance, continuity and resistance. The only limitation is its inability to measure very small Amperage draws like for Carrier condensing gas furnace inducer motors which have an FLA rating of 0.293. Per the manual: Minimum Current Measurable: 0.3A AC or DC I chose this multimeter over Klein's other meters because of the DC measuring ability of the clamp. Just be sure to take the measurement without the magnet attached. Another reason is that it came with a thermocouple for measure temperature. I lost my first Klein thermometer so I purchased two Cooper-Atkins digital thermometers. One was defective and the other's I pulled the probe off after two months of daily usage through screw holes. As a result, I have used this meter to measure temperature more often than with either of my first 3 thermometers. I will keep this meter as it is rugged and dependable for most applications but I will need to purchase another for measuring under 0.3 Amps. It is hard to read the LCD when it is bright outside, but the brightness can be increased by holding the side button. ... show more

  • Instant Favorite At-Home Meter
Style: Clamp
This is instantly my favorite at-home meter. It can do every function that I need (with a line splitter). Auto, HVAC, appliance. Let's get this out of the way first. It's a sub-$100 tool. It's not your work Fluke and it's not a CL800/900. Display is awesome. Contrary to what some believe, the time-out is 5 minutes. I like this to save batteries. Just tap any button to re-illuminate it. For the rare occasion that you need it on for an extended duration, simply hold the button when you turn it on. But don't believe me, simply (gasp) read the manual. For the rare occasion that you are working outdoors in blinding sunlight, no need to be a drama queen. Simply put your beer belly or head in-between the sun and display (i.e. make a shadow) and problem solved. You can do startup amps. Simply use the max-min feature. Again, it's in the manual. Let's do a simple test on a 20+ year old 80W-ish rated crock pot. Line voltage is 125VAC. Theoretical Amp draw is 0.64. Meter (on 10x splitter) is right on. Leads aren't silicone but plenty good for the intended use. I like the mount on the clamp for easy one handed measuring. Note that this is not "frustration-free" (easy-open) packaging. Probably done this way for retail theft deterrent. So if you like keeping the original retail packaging for storage, forget that idea. I've also added the hanging magnet strap, which slides right onto the built-in mount. Always handy on any meter. Folks, this meter is a winner. ... show more

  • When using the DC amp feature, be sure to zero the meter first.
Style: Clamp
Unlike 0ther digital meters, the LCD screen colors are reversed. The background is black and the numbers are silver. I'm still trying to get used to that. Some models mention it as an option, but I didn't see any way to change it.
