I bought a Beckman Tech 310 new in 1980. It still works and is still in spec.
Liar! Only Flukes can do that!!

The orginal made in California Beckman DMMs were very durable.

Telecom Aust standardised on the Beckman in the 1970s, at least in the RadioComms & Broadcast sections.
I think they were put off Fluke by some of their early bench meters.
At my depot, we had a quite early one which was solid enough, & although not trouble free, was easily fixable, & a slightly newer one which was a total pig.
The old "Beckpersons" were rugged & reliable----what more could you want in a handheld DMM?
I never had a Fluke handheld DMM till I left & went to the Private Sector & got the 77.
Hiding at the Transmitter site was one of the Flukes with side push button switches, which I never liked, as one button was missing.
I had a "Dick Smith" clone with the same switch idea, although much more crappily done.
The "convenience" of side buttons never was a convincing argument to me, especially as the 77 offered pretty much the same advantage of "one handed" setting whilst using a conventional rotary switch.
