Description
Solution
Load default settings
Indicates the original calibration and set-up data has
been corrupted and default values will be used.
00000001
WA-1600 only, reference laser is not
stabilized.
This message is normal on power up of the WA-
1600. 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-1600 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. It 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.
00000008
Intermittent signal from the reference
laser during the measurement
window.
Reference laser signal at the Monitor output should
exceed 2.0 volts p-p throughout the measurement
window.
This may be due to partial misalignment of the
instrument internal optics.
00000020
EEPROM read failure. Problem
occurs on power up or when
restoring.
Turn the instrument off, wait a few moments, and
turn the instrument back on.
If the problem persists contact EXFO Service.
00000040
Static RAM read/write failure. This
error may sometimes occur on power
up.
Turn the instrument off, wait a few moments, turn
the instrument back on. If the problem persists
contact EXFO Service.
00000080
Interferometer scan motion error.
Either the scan assembly is not moving or the scan
timing detector is malfunctioning. Contact EXFO
Service.
00000100
Input signal (fringe amplitude) is 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.
00000200
00000400
00000800
Counting errors.
Check input laser for intensity or frequency
instability. If the error persists, contact EXFO
Service.
00001000
Pressure reading is out of range;
range is 500 mm Hg to 900 mm Hg.
If the problem persists contact EXFO Service.
