IMPORTANT: Updating from version 1.00 can effect the instrument calibration. Please read carefully before carrying out the firmware update.

Version 1.01 added two more calibration steps to calibrate the DAC offset in both channels.  These two steps were added to improve the accuracy of the DC offset. 
Version 1.02 fixes a problem which prevented both channels being triggered simultaneously via remote control
Version 1.03 fixes a problem with binary transfers over USB

If updating from V1.00, following the update, the instrument will need to be recalibrated. If recalibration is not performed after updating the firmware, the instrument would perform as before using the current calibration values, however, there will be a message that will pop up every time the instrument is powered on to inform the user that the instrument is not calibrated.

It is recommended that the instrument be recalibrated after updating the firmware from V1.00 to 1.01 or later. The DC offset calibration steps can be performed from the front panel of the instrument with a DC voltmeter without disturbing the existing calibration points.  Instructions are provided in the operation manual.  Alternatively it can be sent off to a calibration facility if traceability is required.   If you do not need improved DC offset accuracy or cannot re-calibrate the instrument, it is recommended that you do not apply this update until calibration is required.
