ARNING
TO AVOID POSSIBLE ELECTRICAL SHOCK, DISCONNECT THE
THERMOCOUPLE CONNECTORS FROM THE THERMOMETER BEFORE
REMOVING THE COVER.
Power is supplied by a 9 volt “transistor” battery. (NEDA 1604, IEC 6F22). The
“xxxx ” appears on the LCD display when replacement is needed. To replace the
battery, remove the three screws from the back of the meter and lift off the front
case. Remove the battery from case bottom.

Selecting
the
T
emperature
Scale
Readings are displayed in either degrees Celsius (ºC) or degree Fahrenheit (ºF). When the
thermometer is turned on, it is set to the temperature scale that was in use when the
thermometer was last turned off. To change the temperature scale, press the ºF/ºC key.

Thermocouple
T
emperature
Measurement
The thermometer displays the temperature of the thermocouple that is
connected to the selected input. In model TK0306, press the T2 key to display the
temperature of the thermocouple connected to the T2 input. Press the T1 key to display
the
temperature of the thermocouple connected to the T1 input. The input selection cursor
indicates which input is selected.
Differential
T
emperature
Measurement
(model
TK0
306
only)
Differential temperature measurement is selected by pressing the T1-T2 key. This
causes the thermometer to display the temperature difference between the two
thermocouples (the temperature of thermocouple T1 minus the temperature of
thermocouple T2). The selection is indicated by the input selection cursor.
HOLD
Mode
Press the HOLD key to enter the Data Hold mode, and the “D-H” annunciator is displayed.
When HOLD mode is selected, the thermometer holds the present T1, T2, and T1-T2
readings and stops all further measurements. Pressing the HOLD key again cancels
HOLD mode, causing the thermometer to resume taking measurements.
MAX
Mode
To select MAX mode, first select the desired input (T1, T2 or T1-T2), then press the MAX key.
The thermometer then records and updates the maximum values for that input. The MAX
annunciator appears on the display. Pressing the MAX key again to exit the MAX recording
mode.
In the MAX mode, press HOLD key to stop the recording of reading, press HOLD again to
resume recording.

Calibration Procedure
Insert temperature probe into https://www.scigiene.com/SCCAL-2-Calibrator or
https://www.scigiene.com/SCCAL-9-Calibrator or
https://www.scigiene.com/TempCalibrator140 at 0°C in order to calibrate precisely, and
then follow directions.
NOTE: regular ice bath methods are not accurate enough to recalibrate these devices in
order to meet stated specifications.
