Product ReviewsHP 34401A Digital Multimeter

A great unit, for the right prine

his is not the most modern 6.5 digit unit, but it scan still hold its own.

The VFD display has class. A lot of class. There is no competition for space like on many more modern units, it is easy to read, and the function is clearly displayed at all times. The available acquisition rates are competitive with current products, given that the accuracy is limited ultimately by things like power-line interference, so measurements need to be synchronized to whole numbers of cycles. The available measurements cover most bench meter use cases. The ranges are excellent (100nV resolution at the lowest range) with good inherent stability and accuracy.

It is dated in that there is no USB or network connectivity. RS-232 or IEEE488 are it. But what do you expect for a meter that hit the market the same time as Windows-95? It speaks SCPI, but can also speak HP3478A and Fluke 8840, should there be a need. Minimal finicky-ness with RS232, adn none with GPIB, in my experience.

Programming via the remote interface is fairly versatile for the time. Triggering response is good, making it practical to do near-simultaneous acquisition across several instruments, even using RS232 (think device testing with a programmable power supply and several meters, for example)

The meter DOES NOT do some measurements that are common today, such as capacitance or generating a histogram, but covers most of what current instruments of comparable class do. This is not the most modern meter on my bench, but when I needed another 6+ digit unit that is stable and accurate, it was the economical option (as opposed to a new 44360A for nearly 4 times the price) for use as a general bench meter and, especially, in remote programmed applications.

An extremely accurate multimeter that can be had for very low prices

This is an excellent meter, even though HP/Agilent/Keysight has ended support for it. Replacement displays can still be found (both OEM and Chinese made), and unless one of the custom chips dies in it most things can be repaired with off the shelf parts.Read full review...

👍

Apart from Keydoght's or Keithley's newest offerings, it's about the best damned multimeter out there. Had one for a long time, then it was stolen; glad to have another.

Most pleased with both the machine and the price. Read full review...
