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: " Microprocessor controlled test set features: AC voltmeter,Sineadder,Line Level meter,Single and DTMF tone decoding and portable battery operation" $550 for a short time. The drawing of the unit shows a square box with a large meter and 16 digit keypad on the right. Bridge and terminate switch. 4 controls labeled Mode, Scale,Vol.,& Level. This doesn't have the typical appearance of Helper products. It looks like a keypad entry version of the Toner 3,Lineman,Sinadder 3 with DTMF decode added. This arrived after Susan took control of the company. I can scan this and upload it if anyone is interested. --- In Repeater-Builder@yahoogroups.com, "Gary Schafer" <gascha...@...> wrote: > > > 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.
