The MC, LC, RM and MK devices from Battery Metric are factory calibrated. The calibration data is stored in the flash memory of the device and all calibration parameters are automatically applied to all regulation and measurement functions. User calibration tools are available in the BA500WIN software application should users wish to perform recalibration procedures. See the BA500WIN manual for more information.
Upgrading the firmware will not impact the calibration settings in anyway. Calibration data is kept is a separate memory area and is unaffected by a firmware change.
Calibration services are available from Battery Metric. For more information visit: www.batterymetric.com/calibration
