Harbor Freight Voltmeter
Posted by BigDaddy on Tuesday, March 5, 2019 7:37 PM

Can't complain about the price, one of mine was free with a coupon, but they both died in the last 4 weeks. 

Both read some absurd number on every setting, today it was 19.98.  Changing the battery didn't help.  There is a fuse inside, but that looked OK.  My 20 year old Craftsman still plugs along.

I have been using four of these for quite a few years and very happy with them.

Compared very well to am expensive meter.

Some years ago I picked up spare fuses ar Radio Shack but no more. I still have some fuses.

I was quite surprised to find out they read about 13.6 vac on my NCE Power Cab about ten years ago. I figured I would take whatever I got as a bench mark.

With a circuit I found online and using the 20ma DC current scale, a cheap DCC five amp meter.

Better wire and probes cost me more than the meters. I wanted three foot long probes and clip leads.

Henry you must have the “touch”, I have somewhere around a dozen of their cheapo meters (the freebee door prize), most have been dropped a dozen times or more and I think they still work.

There was no droping involved in their demise.  Like the old car found in the barn, it ran when parked.

Mine must be just a Fluke...literally.  And I still have my ol' Craftsman DMM that I paid $20 for 15-20 years ago.  It even came with a temperature probe.

I have a twenty year old Fluke model 73 meter that has quite lilterally been through hell with me. You cannot imagine the conditions this meter has endured, and it is still as good as new, except for the grease stains all over it.

My first meter was a Heathkit VOM I built in 1955. Lasted many years until the meter movement gave out.

When I worked for NASA in 1970 I bid on surplus stuff. Got a nice HP tube type VTVM. That lasted until I had to move some years later.

Harbor Freight has some fantastic items.  I love that they allow me to use two coupons!  Their customer service is what to expect from an electronics store.

I have one voltimeter that works great.  The 1st one never worked. Te manager didn't believe me about it not working, so I put into an outlet.  After one probe shot off and caused a spark, that was enough for him.  In this case, the customer was right!

Me too.  I also built their Audio meter for checking audio back in the early Stereo/Binaural days.  Later I just had to have the huge Eico VTVM kit, I think it had a 5½” meter.  Then came the Heath Scope, those were the days.

With a better set of three foot leads I used mine for checking house wiring. No problem.

I use to keep one in the car.

Have  4 of 5 of the HF meters, they're good enough for general trouble shooting and it doesn't matter if they get dropped, thrown(don't ask), run over or lost. Keep one my car and truck.

I have two Harbor Freight meters, the red digital one and a black analog one from a long time ago. Both worked fine until I tested high voltage while they were in a low voltage mode. Oops! I blew up the fuses in both of them. Now I have to decide if I want to spend more money on fuses or just buy another meter for less…..

Solder a single strand of stranded #30 wire across the fuse, I’ve been doing that for years and never a problem.  Those quick blow low amperage instrument fuses are $$$$, the single strand will blow quick enough to protect the innards.

I have eight HF meters hardwired into four MRC Controlmaster 20 PS. The leads where cut and soldered into the track circuits to monitor voltage and amperage of each PS. The readings are comparable to my Fluke meter. This setup has been in place for years. Only problem I have encountered.....leaving meter turned on and 9v battery going dead. Planned for battery replacement when I installed on the control panel, so no problem replacing. Also use HF meter hardwired to rotary switch to monitor AC output of two Lionel ZW transformers running my O- gauge layout. To date, I’ve had no issues.

I picked up my VOM from one of those overstock type stores in Manhattan called Lot Less for like $5. serves me quite well.  I also use an old diet scale that cost me 25 cents at a rummage sale to weigh rolling stock also serves quite well.

I’ve screwed up and blown the ‘single strand fuse’ on several meters and the ‘wire fuse’ worked every time without dinging the meters.

Thank you for the tip. The fuses cost more than a new meter.
 

 So does a new battery.

I really wouldn;t jumper over the fuse. It's bad enough the 10 amp range doesn;t have ANY fuse whatsoever. THatmeans if you overload or short out while plugged in for the 10 amp range, the whole meter will likely just blow up in your hands. That fuse is on the low amp range, and will blow if you exceed 200ma. THere's not much in model railroading that 200ma is enough, most things you would be on the 10 amp range. testing current to a single LED maybe, for the 200ma range.

ANd better quality probes and leads or not - I would never use the HF meter for household wiring - the leads it comes with would probably just melt in your hands if overloaded or shorted. Good probes and leads won't - however, then the meter itself will melt. There's a video of 'fully destructive' testing of that and similar cheap meters.

 A good meter rated for high voltage measurements has VERY expensive fuses - not glass ones. They are ceramic and designed so that the fuse itself will not explode and/or arc. My two good handheld meters have 2 such fuses, one for the low current range, one for the high current range. One learns to be careful on the low current range and not exceed the limit and blow that fuse.

 Saftey/anti-blowing up tip: Start with the highest range, volts or aamps, whatever you are measuring, and work down from there. At least with a manual meter. 14V across the raisl on DCC will show up on the 200V AC range, you just won;t have much precision. But you can see it is 14V which means you cna turn down to the 20V range and not be over range. 10-15ma through an LED wills how on the 10 amp range, again not very precise, but you can see that it is not over the 200ma limit of the low current range, so you can switch to 200ma and test again.

 On an analog meter - it's almost MORE important - overranging one too drastically can easily damage the meter movement as it bangs into the stop at the high end. That is a rather expensive mistake.

 The FLuke 70 and 80 series meters are traditionally "electrician's" meters - made to take a beating, made to measure high voltage and current safely. Hence the rubber baby buggy bumpers around them that keep the plastic case from getting smashed. Definitely good stuff. 

 But not so good for DCC model railroading - the RMS functionality will actually read way off, not more accurately, when measuring DCC. None of my good quality meters reads DCC track voltage as accurately as the cheap Harbor Freight meter. Except my venerable old Fluke 8060. One of the early LCD handhelds, still of the type where the range selection is pushbuttons down the left side of the meter instead of a dial knob. It does true RMS measurements of sine, square, and triangle waves at frequencies up to somewhere near 30KHz. Most RMS meters only do sine, up to maybe double lien frequency, 120Hz. Or a True RMS meter than can handle different wave shapes, but also only up to a limited frequency range, far below DCC frquencies. So while it sounds like they shoudl do better than a cheap meter that does no sort of RMS measurement at all - actually, they don't, where DCC is concerned. 

 I bought the 8060 used on eBay, pretty cheap. It needed some cleaning up, and internally there is a zebra strip connecting the LCD to the board which needed a good cleaning, as dirty/poor contact was causing some segments to not show up properly. But after that - still works good. It probably should be recapped and calibrated, but it actually measures within spec compared to my reference source. I have two newer full feature meters though that I use much more, excpet for DCC track voltage, becau while they are both True RMS meters, the top frequency is too low to accurately measure DCC. The one is quite neat, user updateble firmware, data logging to an SD card, and Bluetooth connectivity to dat logging and display apps for IOS and Android. 

 Most of the time I jsut use them o measure resistors - I can;t see the colors very well on those new blue packaged ones, and some of the colors look way too much alike. I n certain positions it's prety easy to figure out what color it is trying to be, since the other option makes no sense. But, it's also just as easy to touch the resitor across the test leads and make sure I am putting the correct value in. Maybe I should just buy better quality resistors with darker, clearer markings.

Randy I agree with you.
 
I think most model railroaders that pop the fuse in the HF meters are doing it accidently.  As you said there is no fuse in the HF 10 Amp connections so they are popping it measuring voltage on the 200ma setting.
 
I set my power supply to limit at 2 amps and a single strand of #30 blew it easily.  It did get hot and melt at 1 amp so it would be safer if it was in the glass rather than tacked to the outside.  I continually grab a HF meter to check voltage (24 volts and lower) and forget to check where I left it.  The HF is the worst offender because of the on off switch isn’t part of the selector switch like most normal meters.   It’s too easy to turn on and go.
 
I agree about not using the cheapo meters over 50 volts or so for non electrical type guys.  I go to my Fluke or Triplet 360 for over a 100 volts and I’ve been using meters for over 70 years.

Not so fast.  Fuses are there to prevent expensive smoke!

Also, some Flukes use an expensive fuse, which must be replaced with exactly the same type, as it is also a shunt.  Just stuffing any handy fuse in there makes the ammeter function useless, as it needs the shunt created by the fuse specified for it.

I don’t remember ever having to replace the fuses in my Fluke, It did come with a spare 1 amp and 15 amp fuse and they are still in the box.
 
The Fluke manual doesn’t say it’s a special fuse just fast blow with without a Fluke part number.

I bought two electronic items at Harbor Freight not long ago.  A cigarette lighter phone charger for my phone and a battery monitor for my 69 classic car.

The charger for my phone didn't work right from the start.  I wasn't about to stick the battery monitor on my classic car after that.  I returned them both.

You get what you pay for.  I bought a battery Governor from Napa that is on my classic car now because my security system draws so much current from the battery it needs to be continually trickle charged.

I will pay for the good stuff.  Don't get me wrong.  There is a lot of good stuff from Harbor Freight I buy and I am happy with.  Just Not Electronics

I normally buy a tool of some sort and use the freebee coupon for my train goodies.  I did get one meter that was DOA but my wife stopped by and they replaced it no questions ask.
 
You’re right about you get what you pay for but normally everything I get at HF does what I need, even stuff non railroad related.  I would rather buy a cheapo to tear up than something expensive, I’m good at tearing stuff up.  I buy all of my drill bits from HF and as I’m not a machinist I can’t tell the difference between the HF 10 bits for less than the price of one at a big box store so I’ll hang in there.
 
I have about 10 of the HF volt meters (I always have one within arms reach, I’m lazy) and for the most of it they’re pretty accurate, close enough for model railroading.  I bought a A803L Cen-Tech meter off eBay for about $6 several years ago and I keeps up pretty good with my $300 Fluke, Cen-Tech also makes the HF meter.
