5.3.1 Analog Hardware Calibration

Both Power Debugger analog channels requires calibration to achieve full measurement accuracy. The hardware is calibrated during manufacturing but it is also possible to do a re-calibration to get the most accurate measurements. The calibration procedure itself is automatic but before the calibration procedure can be started it is necessary to disconnect all external wires or jumpers from the analog channel pins and the voltage supply pin (the pins next to the ammeter symbols, and the pin next to the voltage source symbol on the Power Debugger). The calibration is triggered through the software front-end used to interface the Power Debugger.
