Dwyer BTM3 - Manual (Page 2)

AMBIENT TEMPERATURE ADJUSTMENT
(All reset adjustments must be done using an adequately agitat-
ed temperature bath operating at a known temperature.
Instruments used to monitor such a bath require a greater accu-
racy than the thermometer being adjusted.)
The Series BTM3 is equipped with an external reset adjust-
ment. To make an adjustment, use a flathead screwdriver or a
small wrench to turn the slotted hexagonal adjustment on the
back of the case. Do this until the temperature pointer reads the
appropriate temperature on the dial.
OPERATION
To obtain a minimum or maximum temperature reading on the
Series BTM3, simply turn the knob on the center of the dial in
the indicated direction to move the red pointer to the current
temperature (black pointer). If the red pointer is above the black
pointer, the red pointer displays the maximum temperature. If
the red pointer is below the black pointer, the red pointer dis-
plays the minimum temperature.
MAINTENANCE
Upon final installation of the Series BTM3 Bimetal Thermometer
with Maximum/Minimum Temperature Pointer, no routine main-
tenance is required. A periodic check of the system calibration
is recommended. The Series BTM3 is not field serviceable and
should be returned if repair is needed (field repair should not be
attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes.
