MasterLab Analyzer appears
to “lock up” upon successful
connection.
1. Upon successful connection, the instrument “lost
track” of which amplifier was last in use. This may
happen when changing computers, or under
conditions of improper disconnection. (This is
being investigated and addressed.)
If in a transmission DCM, switch to a reflectance
DCM, then back to the transmission DCM. If in a
reflectance DCM, switch to a transmission DCM,
then back to a reflectance DCM. This procedure
will send a clear on/off signal to each amplifier,
and will prevent any cross-communication that
could lock the instrument.
Depending upon Configure, Options selected, and
the tests performed, this condition may manifest
itself as one of more of the following problems:
• Bad amplifier voltage in Self Test
• Auto-Linearization Error
• Blank Screens in Performance Test
This situation does not occur once a given
computer, running Vision, has “synchronized”
settings with the MasterLab instrument.

Lamp does not come on when
instrument is connected.
1. Verify communication with instrument. Click on
Acquire, Disconnect, then Acquire, Connect, Select
DCM to verify proper connection. If lamp does not
come on, replace lamp according to instructions
provided in part 9.3 of this manual. Do not
attempt to replace lamp with AC power applied.
2. Lamp may be burned out. This should not occur
for thousands of hours of normal use, but could be
caused by jarring or other physical motion. Replace
lamp.
3. Instrument thermal shutdown may have occurred
due to high internal operating temperatures.
Determine cause of high temperature and correct
before subsequent operation. Service may be
required.
