Watchman 9-90, Owner'S Manual, Page: 3 / 6

Replacing Thermocouple Cable/Probe
Replaceable thermocouple cable length: 6 feet
Probe length: 4 inches
Probe diameter: ¼ inch
Maximum probe temperature rating: 1950 degrees
Excessive temperatures and long-term use will wear
out the high-temperature probe. If your batteries (9-90)
are fresh but the monitor begins to operate erratically,
you are probably due for a new cable-probe assembly.

DISPLAY TEMP button
Continuous display of temperature readings is
unnecessary and consumes battery power (9-90). Condar’s
programming of Watchman’s LED visual read-out limits
the temperature display to what’s necessary during
normal operation. In the target operating zone of 700
to 1350 degrees, you’ll view your current temperature,
briefly,
once per minute automatically . A single press
to the manual DISPLAY TEMP button, at any time,
commands continuous read-out for 2½ minutes.
Lb in visual display (9-90 only)
The LED display signifies Low Battery.
Replace one battery. If read-out still continues and you
installed two, replace both batteries. Limit pressing the
DISPLAY TEMP button to minimize power consumption.
