Needed Impedance meter

[Ric-Paul Hammink]

Hi,

I've searched the web, the telephone guides and a couple of companies.

I just cannot find a simple, portable, suitable impedance meter.

All I need is a meter that generates a 1000Hz signal and usus that to
measure the impedance of a speakerloop. It will vary from something
like 10 ohms to 1000 ohms (100V systems)

We even have 2 of them !!!! But they were made by Sennheiser (yes, the
one from the headphones) but they no longer make them..... The ones we
have even have a selectable measuring frequency, but that isn't even
too important...

Maybe I'm using the wrong English name, because I cannot imagine that
noone makes these things anymore.

Help!??!?

I can only guess you're searching for "impedance meter." Perhaps you
should try "impedance bridge."

How about:

FYI, my personal favorite is the H-P 4800 vector impedance meter.
These appear on Ebay occasionally, and the prices are usually
affordable.

Try Klay Anderson at klay@klay.com
Also try getting in touch with Bogen, Rane, Shure, any of the PA equipment
people.
I've used units calibrated to give the power consumption in a 70 volt line
rather than the impedance of the line, so you might want to look for audio
wattmeters as well.

Needed Impedance meter

All I need is a meter that generates a 1000Hz signal and usus that to measure
the impedance of a speakerloop. It will vary from something like 10 ohms to
1000 ohms (100V systems)

At work we periodically needed to make this measurement. We used a 10 ohm 2
watt resistor in series with the load. All it took was a simple math
calculation to get the load impedance. We had it set up on a programmable math
calculator. Be sure the resistor is less than 10% of the load impedance.
Lessens the error.
