If the Service indicator reappears after a PACER cycle (even after
performing the mirror cleaning procedure above) check the sensor
balance adjustment. Improper adjustment of the optical balance is the
most common cause of instrument malfunction. In addition, new
systems may require an optical balance adjustment after one or two
months of operation.
IMPORTANT:
Always clean the mirror as described above before
performing an optical balance.
Set the sensor mode to HEAT, wait one minute, then observe the
balance indicator. If only the lowest bar is illuminated, or the lower 1/
2 inch of the status bar, the sensor is properly balanced. If not, balance
the sensor according the procedure below. The location of the balance
adjustment screw for various sensors is shown in Figure 7-1 below.
