AstroAIDigital Multimeter, TRMS 6000 Counts Auto-Ranging Voltage Tester Voltmeter Measuring AC/DC Voltage Current, Capacitance Resistance Frequency Temperature Continuity Diodes with NCV

I have just received the unit in the past week or so, I have only used it to check some batteries.I was surprised to see that the batteries were preloaded in the unit, at first I thought I may have received a return item, but no, it was not a return. It appears to me to be very solid, it is well constructed, it does not feel or seem cheap.I feel it is a very good unit well worth the price. It will do everything I will need a multimeter for. This replaces my very old cheap little analog multimeter I bought from Harbor Freight many years ago. The instruction book is good though the print is tiny. I will be buying a hard case to store it in.

Back in the mid 90s while I was in college, I got my first DMM at Radio Shack for $60. It has no auto turn-off and uses 6 AA batteries :[. I have used some fancy and cheap DMMs (Fluke, BK Precision, and low cost one from Harbor Freight) at work for over 20 years. I was surprised to see there were low cost DMMs with many new features on Amazon. So I tried TRMS 6000 for $30.Cool features: Red color (easy to find); backlight (handy working in the dark); AC and DC auto detection (no worry to select correct type of power when measuring current/voltage); No need to press FUNC button to switch to continuity check; Green LED indicators.Not good enough: Only one decimal in measuring Ohm (need 2 decimal points in my line of work, EE); NCV Live was triggered when moving my hand over the sensor at the top and caused confusing.Comparing voltage measuring against other DMMs at work and found almost identical. I measured a 9V battery using BK Precision DMM and this DMM. BK Precision showed 9.096V (3 decimal points). This one showed 9.09V (2 decimal points).I have not use all its features yet. I will update when I see other pro and con. For the price I paid, this is really cool DMM.Note:If you want something smaller (with a bit less features) for easier to carry around , go for TRMS 4000.I found KAIWEETS has almost identical DMMs as AstroAI's (4000 and 6000 models) in black color. Just wonder if they were all made by the same mfr and sold to 2 different vendors.

Like the versatility and the features. Work light, noncontact AC power detector plus the other add on functions. The auto power off saves batteries and the batteries are cheaper to replace being AA rather than 9V. This is my second one of these meters. Used the first one for roughly a couple of years. First one got wet working on a sprinker and quit working. Immediately ordered another. Then took the first one apart to dry it out. Really like how sturdily the insides were build compared to other meters I have disassembled. Got it dried out and rinsed off with electronics cleaner and reassembled, it is back to working. The older one has taken numerous tumbles to concrete and steel and was still running till it got wet.I have 2 complaints about this meter.1. One was in the original write up on the meter. The auto ranging is slow to change ranges so if you are checking a bunch of wires for power or reading resistances there is a several second delay between wires while it ranges each new wire. With one or two wires that is no problem but if you are checking dozens or hundreds it would be way nicer if it ranged faster. Get very frustrated with the wait each time.2. Don't know about this meter but it looks identical to the original one and is the same model and the originals test leads were failing. Had a crack in the insulation in one lead and both leads there cracking at the strain relief to the probe. And this in only 2 years of moderate but fairly rough service use. Suggest plan on getting better replacement leads to put with it.While better water proofing would have been nice I truly do not think I can fairly expect it at this price point. Dreaming anyway. :) Overall for the price point I have been very happy with the old meter and expect that same of the duplicate new one

Works good and precise except with temperature measurement. I like the background panel light, big numbers, soft leads, overall its a good tester.

Likes:1-Built in probe holders, makes use as a field instrument safer, one probe can be attached to the meter, the other in hand to make checks.2-Dual display ie. AC volts an Hz3-Boldness of display, the segments for the numbers are "thick and crisp"4- Quick responding "bar graph" Even though I use analog meters also, this bargraph display is pretty good, and appears to react quicker than my VC99.5-6000 counts display, at the price point offered this is a good value, I have found 6000 counts to be far better for me than 4000 or 2000 count DMMs that I own.6- Accuracy, I am impressed with both of my AstroAI 6000 DMM's specifically on VDC.. I have a reference standard and the photo shows these "babies" are right on the money.7- The meterface backlight is good and the lighting is relatively even.8- I see having the built in flashlight can be a real handy "field feature"Features I am indifferent to:1- When the range is selected, the correct "jacks" (to plug into) light up, I guess it is a safety feature, I consider it a gimmick.. it is cute though.2-NCV, (non contact voltage) most of the newer DMM's feature this.. could be handy I guess.. I'm just not willing to trust NCV yet..Dislikes / shortcomings1- When trying to measure HZ (frequency) I used 120VAC supply it worked well and was quite accurate, however when I use a frequency generator @ around 1 VAC this meter does not see the frequency. In contrast my AstroAI WH5000A (currently named DM6000AR) does indicate frequency at these low volts.Summary: This AstroAI M6KOR is a great buy, I still like my AstroAI W5000A for it's larger display, but the addition of dual display and bargraph are useful to me. The M6KOR in my opinion is a better field use meter.

Good DMM. As advertised!

Was ordered as a gift for my son, he seemed to really like it. Seems to be well made.
