"Temperature/Pressure
Sensor: Out of Range"
The pressure or temperature reading is out of range; the
normal pressure range is 500 to 900 mm Hg and the
normal temperature range is 1 to 50
°
C. A temperature or
pressure reading of 0 usually indicates the sensor is not
connected or has a broken wire. Contact EXFO Service.
00001000 and
00002000
"Reference Laser: No
Fringes Detected"
Detector failure or insufficient signal amplitude from the
reference laser. This may be due to a decrease in
reference laser power or a major misalignment of the
internal optics. Contact EXFO Service.
00000004
"Input Laser: Intensity
Too Low"
The input laser signal observed at the Monitor output
must exceed 1.5 volts p-p amplitude. Set gain to auto.
Check input laser power. Increase the intensity of the
input laser beam entering the instrument.
00000100
"Input Laser:
Wavelength Out Of
Range"
Check that the laser is operating within the specified
wavelength range: 700-1650 nm.

Solution
Load default settings
Indicates the original calibration and set-up data have
been corrupted and default values will be used.
00000001
WA-1650 only. Reference laser is
not stabilized.
This message is normal on power up of the WA-
1650. The display shows warm-up time. Turning
power off and on again will restart the warm-up
timer. If this condition occurs after initial warm-up
then contact EXFO Service.
00000002
WA-1650 only. Reference laser is
over temperature.
The laser stabilization circuit is indicating an over-
temperature condition. Turn the instrument off, wait
15 minutes and power up again. If the problem
persists, contact EXFO Service.
00000004
Detector failure or insufficient signal
amplitude from the reference laser.
This may be due to a decrease in reference laser
power or a major misalignment of the internal optics.
Contact EXFO Service.
