7-8 Maintenance
“Balance” Remains on the
Status Line
When the word Balance remains displayed on the front panel for
more than 15 minutes, the instrument has not recovered from a
PACER cycle.
Check that the sensor and sensor cable are connected. If necessary,
connect them, and the unit will complete the PACER cycle after a
short time (5 to 15 minutes).
The sensor optical bridge may be out of balance (see Balancing the
Sensor Optics on page 7-2).
No Analog Output
If there is no analog output, but the digital display indicates correctly,
check the analog output scaling. For the VGA unit, see
Analog
Outputs on page 4-6. For the 4x40 unit, see Function 1 — Analog
Outputs on page 5-4.
No Serial Output
Check the serial port programming for proper settings. For the VGA
unit, see instructions on page 4-18. For the 4x40 unit, see instructions
on page 5-5.
