Hmmm, we hadn't planned for it but it might not be too tough to design one in. We sell so few ammeters anymore compared to voltmeters, we figured most people would want a voltmeter (which is available in Performax). If we added an ammeter it would be a shunt-based design, with wiring from the shunt to the ESP for monitoring. What amp range would you be looking for?
