C-3
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 occur on power up.
Turn the instrument off, wait a few moments and
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.
00001000
Pressure reading is out of range;
range is 500 to 900 mm Hg.
If the problem persists contact EXFO Service.
00002000
Temperature reading is out of range;
range is 1 to 50
°
C.
A temperature reading of 0
°
C usually indicates the
temperature sensor is not connected or has a broken
wire. If the problem persists contact EXFO Service.
00004000
Input laser power error, power is out
of range
Check that the laser is operating within the specified
power range. If no wavelength is indicated, then
1550 nm is assumed in the power calculation.
00008000
The wavelength (or frequency)
measurement is out of the range for
the model setting.
Check that the laser is operating within the specified
wavelength range: 700-1650 nm.
00010000
Power null failure.
The background power reading is above the
threshold for the power null function. Make sure an
input laser is removed from the instrument and the
fiber connector cap is on.
00040000
WA-1650 only. Reference laser peak
power outside the 60 to 85% range
necessary for proper operation.
Recalibration is necessary. Contact EXFO Service.
00080000
Input power too high.
Check if input laser is above the specified maximum
input power.
00100000
00200000
00400000
00800000
Internal communications error.
If persistent, contact EXFO Service
