This procedure must be carried out when both the AlcoCal

and the

1. Prepare the AlcoCal
®
standard
Note the value of the AlcoCal
®
to be used (making

Now put it into its Calibration Adjustment Mode. This
ensures the SD-400 is in its correct temperature range;
allows an actual resetting of the instrument’s analytical

the subject test memory. So insert the Dongle into the
Communications Port on the side of the instrument.
Now switch the instrument on and then IMMEDIATELY
press and hold down C. This MUST be done BEFORE the
