Excellent kit and good quality. Modified mine to be a voltmeter.

Jasper You're relying on the accuracy of the 1M versus 10k/1k resistors as a voltage divider to make it into a 200mV full scale signal.Two comments: a) for this relatively high voltage purpose, go with a 2V full scale readout. The Vref module is a 2V5 one, so simply replacing the 56k R2 with a 3k3 or so should give you the adjustment range to use a 1.00V Vref. That also gives you an easy 2V range. b) put trimpots in the 20V/200V to 2V dividers.

zeke_ I did think of doing that but this seems to be accurate enough and was simple. :-)
