That was an auto ranging voltmeter. They were rather expensive at the time,
compared to nowadays. As I remember it you could select auto range, or lock
it in a particular range.

Whoa!
Bill actually went through with this? I never seen this as a production item
although the idea of a service bench Analog/Digital voltmeter was something he
was interested in doing. The DMM's A/D section was to go to an integrator and
drive a meter for peaking or nulling. My understanding w

I'm a late comer to picking up extra Helper Instrument Equipment
but I now have a modest collection of a few items like the Sineadder
and a few of the antenna match boxes. I hadn't thought about it
for a while bu
The Mod Box was a great idea during it's time. Only the IFR-1000 at the time
had the provision to use a microphone with a pre-emhasis network. Most all the
service monitors only allowed an internal tone or external audio gen. Some
allowed the mix of both. The Mod box was sort of like a microphon
No Gary. I meant Sineman. I'm fully aware of the lineman. That was a bit
overpriced for what it did. We had two Nortel units that we bought ex-telco
that did the same thing elegantly.
The Sineman was a unit that we received a mailed brochure. I'm looking at it
now. The description: " Microproce

The idea of the dual meter unit was to be able to quickly go thru a circuit
without having to touch the meter to change ranges or change to AC or DC. If
you stuck it on a DC circuit it would read that right. If you stuck it on an
AC circuit it would read that.
Also you could read an AC voltage rid
