A little more information for the thread...
The Simpson260.com site does have specs for most versions of the meter, but
does NOT quote specs on the 5000 volt range for any of these models.
There are thousands of older Simpson 260s still in service. However a
call to the factory brought this chilling response: Simpson no longer
supports any version of the 260 earlier than Series 8. They will not service,
calibrate, supply manuals, parts or ANY information about them, except to say
that they pose safety issues, and will not elaborate beyond that. I believe
that they want to see them all go away for liability reasons. In fact,
their Series 9 260s have a maximum voltage rating of only 600 volts.
I think that SM0AOM described the problems attendant with high voltages,
and Simpson's reluctance to accept liability for HV accidents, but I'm
disappointed that instead of working to resolve the issues, they chose to avoid
them entirely. This is rather like putting a speed governor on car engines
to prohibit going faster than 20 MPH, because everyone knows that fatal
accidents are more likely at higher speeds.
Sounds like Simpson's latest design was performed by lawyers, rather than

Steve, the 260 is a fine VOM but, it is old and the calibration can't be
trusted until it is checked with proper equipment.
The resistors change value with age and who knows what damage could have
occurred in the past due to operator error etc.

I have a Simpson 260, Series 5. What I don't have is the manual for it.
What I'd most like to know is what accuracy it's rated for on the 5000
scales, both AC and DC. I believe the meter is rated for 2% of full
accuracy up to 1000 volts DC and 3% on AC, but I haven't been able to
down a number for the HV scales.
Your help, as always, is appreciated!
