QUOTE (Dadd @ 18 Feb 2007, 01:12) <{POST_SNAPBACK}>One feature of the Power Cab which wasn't immediately obvious to me is the ability to replace the clock readout with an ammeter showing the current draw on the layout.
Glenn.

That is a good feature that would be very useful for all systems.

There has been a lot of discussion (mostly on other "specialised" DCC) groups on the diffeculty of measuring the current draw on the layout. This is mainly because the output to the track is neither AC or DC in the conventional sense, making it diffecult to obtain an accurate reading. There are a couple of fairly expensive meters/indicators available that do the job, however there is a simple solution - connect your ammeter between the power supply & the controller/amplifier, take the reading with no load on the layout (it should be minimal) then the current showing in operation (less the first reading) is the load taken by the layout - simple !

Agreed - I have suggested this method before (& use it myself) & as you say it's easy. About all I can add is that if you have a fluctuating reading then a analogue meter can be better than a digital one.

Well spotted John - just goes to show that I don't always read the posts properly !

At least I did'nt contradict myself !
