1. Features
This thermometer can be used for stove pipe and chimney temperature monitoring.
The meter contains two alarm settings for a built-in buzzer. One can be used for high
limit alarm and the other can be used for low fuel alarm. It also has a third alarm for
the connected external buzzer that can be placed at different floor from where the
stove is located. The gauge is powered by 12V DC through an AC adapter (included)
for continuous operation. It can also be powered by car battery.
POWER - 12V Power supply input
OUT - Output for external buzzer
INPUT - Temperature probe input
Figure 2 shows the terminals of the meter. Connect the 12V DC power adapter to the
terminal 1 and wall outlet. Connect the external buzzer connector to terminal 2. The
polarity for this socket is center pin positive (+), outer collar negative ( ). Connect the
K thermocouple to terminal 3. Please note that thermocouple connector also has
polarity. The wide blade should go to the wide slot.

5. Keys for measurement operation
Figure 3 shows the function keys during the temperature measurement operation
(The function keys for configuring the meter are discussed in the later section)
Notes:
1.
Silence the alarm.
When the temperature reaches the alarm temperature, the
alarm indicator will flash and meter will start beeping. Press shift key once can
temporarily silence the alarm. Alarm will be retriggered if the alarm set temperature is
reached again. To permanently deactivate the alarm, set AH=AL.
2.
Show peak value.
Press down key once to show peak temperature; press again
to show the time when peak temperature is reached (count from the start of
temperature rising, display unit: seconds). If the temperature continued rising, a new
peak temperature and its time will be recorded. They will be memorized even after
power is restarted.
After power is restarted, previous recorded peak and its time will stay in the memory
unless: 1) there is a new peak temperature higher than the previous peak, 2) or the
memory has been reset. Hold the down key for 2 seconds will reset the peak
temperature and its time to 0. The new time is counted from restarting the power or
from reset (display unit: seconds).
3.
Change brightness.
Press up key once to show the dimmed display reading.
Press again to show the normal brightness display reading. The brightness of the
dimmed display is determined by the parameter brit described in the later section of
the manual.
