Dear Dan, Thanks for the quick reply.? The measurements are all at 12v.? I realise that it would be higher at lower voltage and did take that into account when using the 10 sense resistor.? I used a linear bench supply and increased the PSU output voltage so that it overcame the 'burden voltage' of the sense resistor leaving 12v at the QMX input.

If you see 90mA then, while 100mA is higher still, that reassures me a little.
