With software version FW1.6 the calibration procedure was redesigned.
In principle the procedure is similar to the previous one, but now the
technician will get more information and also more adjustments are
possible.
* Take the seat ergometer to an elevated position, e.g. between
two solid chairs.
* Support the supine ergometer so that the load unit will be in a
horizontal position.
* Display the service menu and select menu item „Load
Calibration".
The screen shown at right appears.
The offset voltage of the WSG measuring device is displayed.
This voltage should be within a range of 60 mV to 80 mV.
If the value is not within that range, it should be adjusted by
means of a potentiometer on the MRD board (see section E-2.3
under „RPM Board: Replacement and Adjustment Procedure").
