Set-up items 7 to 10 are used to calibrate the A/D of the instrument. This should be done
30 minutes or more after the instrument has been on, approximately once every year. The
calibration constants are retained in battery backed memory unless a ‘COLD START’ is
performed. Connect a 3 1/2 digit multimeter negative lead to the test point marked ‘C’ to
the right of the PCB on the inside of the door (labelled ‘REF VOLTS’). Measure the four
voltages on the test point marked 1 to 4 with the positive lead. Refer to Figure 6.2 in the
