Any about here got one of these? I found one yesterday at a thrift store for 20 bucks, and I couldn't pass it up at that price!

My initial testing shows the meter to be dead, with no current flow at all. The meter is designed for a LiIon battery pack (not present) or a 6 AA battery pack. Someone seems to have cut a 4 wire lead from a LiIon battery and grafted it to a 9V battery snap for connection to a 6 AA holder.

The connections made don't make sense to me....with 2 of the 4 wires shorted together.... and indistint pictures I've found of the 6AA pack appear to have just 2 wires.

If anybody happens to have one of these meters with the optional battery pack, I'd greatly appreciate knowing the connections to the 4-pin plug..

A positive point... the power supply board appears to be diode protected, so the meter should not have been destroyed by reversed polarity connections.

Thanks,

Jon

 

The response has been so tremendous here! Thanks so much!

For the sake of anyone who may find this post in the future, I got busy with an an ohm meter and figured out the battery connections. To use this meter with alkalines, get a 8 cell battery holder with the cells oriented parallel to each other across the short dimension.

Make the following connections to the 4 pin battery connector:

Pin 1 – battery positive
Pin 2 – open
Pin 3 – battery negative
Pin 4 – open

The meter will power up, and properly recognize that alkaline batteries are being used.

I was rewarded with a mostly functional meter that cost nearly $5k when new. Not bad for $20 plus an $8 battery holder!

The 4th input channel (blue) is open (reads 0 volts and infinite resistance for all functions) but it's not needed for most functions.

Significant functions are a TDR (Time Domain Reflectometer) that will meter the distance to cable opens, shorts and other faults to 10k meters. A cable length feature for paired cables to measure length of an open cable pair (using capacitance) – great for answering the question about how much cable is left on a spool. Leakage tests.

It does make my head hurt – the meter is based on Telcom standards...so RED equals negative and BLACK equals positive. Ouch.

 

That would be a very powerful meter with all of those functions available. And it seems it should also be able to function as a phone. You got a great deal on that one, hang on to it!!

 

If only I still had an analog phone line


Just in case anybody else happens across one of these.... the connections appear to be tip jacks, to fit standard test lead probes. The are not. They are actually 2mm banana jacks, which I had never seen before. Later releases seem to have used standard 4mm banana jacks.

 

The telecom provider companies love to have non-standard connectors for their equipment.

A suggestion is that the blue connection is for a communications function, to use it as a phone.
So you will need to locate an instruction manual or user manual.

 

The jacks are 2mm banana jacks (which I had never seen before. Test lead tips sort of fit, but are too tight.

The blue jack is an additional input, at least in some modes, and you can switch between measuring between red & black and red & blue. There are a dozen or more relays in this thing, and many at a time click as you rotate the function knob between different functions.

The operator's manual is available online. But I discovered almost everything in the detailed and comprehensive operator's manual is available on the screen of the device.

I have not found a service manual, and the company doesn't have a service manual or other documentation.
