No frills, just superb accuracy and speed
My 33478a is at least 20 years old and works perfectly. Superb accuracy. There's no bells and whistles on these- you can measure AC/DC voltage and current, and resistance, and that's it. No math functions, memory, continuity, etc. But you can measure anything from 300V down to 100 -nano- Volts, with the autoranging settling in to the correct reading in under a second. I have handheld meters with lots more features, but nothing that matches the speed and ease of use of this precision instrument.Read full review

Excellent value
The display isn't great to read, but it's acceptable, and it's a high quality benchtop dmm. I recommend it with a caveat: if you're on a budget, it's a far better choice than a no-name meter with a sexy display and bad qualityRead full review

HP 3478A Digital Multimeter
Beautiful meter. Typical Hewlette Packard quality. May not be 'State of the Art' but this kind of measuring equipment is ageless. Just replace the calibration backup battery every 20 years or so and your good to go! Highly recommend for the technician's bench.Read full review

Good accurate meter, but...
1st off check the battery, OK, tested some voltages, again, OK. Then I checked all my test leads to see if any would fit in the front pkanel jacks- no go. not a one of my test lead sets will seat in the jacks. Now I am searching for leads that will work.
This is info that should be mentioned, with possibly a source listed for leads. I will alter this review when I have found leads, with a source.Read full review

Solid DVM Choice
Older design DVM but still a solid bench-top performer. Arrived working correctly and within calibration. Excellent 4 wire ohms performance, good thermal stability. Newer color LED meters look prettier but the HP3478A is more likely to be working years from now. Read full review

As good as any of the Fluke or BK meters.
A very good DVM but takes special equipment to set up the self calibration.
It is accurate in operation but bu a high contrast display with backlight ould be the only thing to improve.

Great basic measurement device
Great Value for money. Precision is good and battery still fully charged all these years later. Amazing build quality.

Terrific bargain bench DMM
The 3478A shows the same value(s) as my Fluke 8842A and HP 3455A. It has turned into my go-to DMM. Highly recommended for the bench. The LCD display isn't "LED" bright but is clearly visible. These 3478A's are a terrific bargain if you find a clean one. Read full review

Bargain high quality DVM
These instruments are a bargain on eBay...they are accurate and reliable, and for my applications the range is such that the resolution is as good as an HP3456 6.5 digit unit.
Calibration is closed cover, very simple.Read full review

Excellent multi meter and price.
The meter has exceeded or met specifications and will be a useful addition to my lab.
