Bench DMM that can measure 1000Vac?

[Jester]

I picked up a Clarke-Hess calibrator it can output up to 1000Vac. All of my bench DMM's are limited to 750Vac. It seems most of the common DMM's are limited to 750Vac. 

I recall years ago doing a transformer excitation test and the voltage was in that neighborhood, I thought well it's a Fluke there should be some overhead. The over-voltage protection kicked in shortly after, a barely audible click and the meter was done. I don't want to repeat that mistake.

Anyone have a bench DMM that measures up to 1000Vac?

Yup. An old Fuke 8600A. Top range is 1200V, AC or DC. 4.5 digits, quite the instrument in its (long ago) days. :-)

Fluke 289

289 is not considered a bench meter by most people.

My vintage Fluke 8000A was rated at 1200Vrms sinusoidal on AC, measuring up to 1199V.  While it is capable of it, I never used it on anything above main voltage, nor do I have any source that generate above main voltage.

OOPSIE ... poor reading skills on my part

You could have buy or make an high voltage probe / divider   at 1kv ac  youre slightly playing with fire ?? 

You have some 3 - 6 kv probe for a mere 60$ usb on Ebay ?? sometime less ?

Having said that, despite it is not officially a bench meter, the 289 is as capable, or more capable than many low end bench meters.  So your recommendation is sound, just that it is not technically a meter plugged into the outlet and can stay on indefinitely. 

However, if I have to come close to 1kV AC, I would take a professional handheld Fluke over any bench meters.

Not a DMM, but an AVO Model 8 could do it!
The early ones went to 2.5kV, & the later ones to 3kV, if I remember correctly.

It is important to note that the frequency of the AC will have a huge impact at high voltages.
Measuring 1kV at 60 Hz is a lot easier than at 10 MHz...

Yep, my AVO 8 Mk5 does 3kV for AC and DC.

[NoisyBoy]

Absolutely, the Fluke 8000A stipulates a max of V*Freq < 1E7, which puts the max frequency at 8.3kHz at 1200V.

Datron 106x, 107x, 108x, 1271, 1281.

[MadTux]

.....1271, 1281.

Yeah, sacrifice 2000+$ DMMs with about as much unobtainium inside as possible to the lighting gods until the magic smoke comes out
HP 3456A does it as well, until the AC divider hybrid releases the magic smoke.
How do I know? From experience , but at least it's not 2k$ and somewhat repairable...
