2. Displaying Temperature
• Press “HOLD (°C/°F/K)” for more than 1 second to select the
correct temperature unit.
• Hold or attach the thermocouple(s) to the measurement
location. The temperature reading appears in the selected
display.
• Press “T1/T2 T3/T4 (T1-T2, T3-T4)” momentarily to toggle T1/
T2 or T3/T4 reading in the primary display.
• Press “T1/T2 T3/T4 (T1-T2, T3-T4)” for more than 1 second
to scroll T1-T2, T3-T4 or the internal temperature of the
thermometer in the secondary display.
• NOTE: The display shows “----” when a thermocouple is not NOTE: NOTE:
connected. The display shows “ ” (OVERLOAD) when the
temperature being measured is outside the thermocouple’s
valid range.
3. Holding the Displayed Temperature
• Press “HOLD (°C/°F/K)” momentarily to freeze the readings on
the display. The display shows “ HOLD ”.
• Press “HOLD (°C/°F/K)” momentarily again to turn off the “
HOLD ” function.
4. Viewing the MIN/MAX/AVG Readings
• NOTE: MIN/MAX and AVG values are captured only while this NOTE: NOTE:
mode is active. Exiting the MIN/MAX/AVG mode will clear all
values.
• Press “MAX/MIN” momentarily to step through the MIN
(minimum),MAX (maximum), or the AVG (average) readings in
the secondary display.
• The elapsed time since entering MAX/MIN mode appears with
the average reading.
• The time at which the MINIMUM or MAXIMUM occurred
appears with the MINIMUM or MAXIMUM reading on the
display.
• Press “T1/T2 T3/T4 (T1-T2, T3-T4)” momentarily to toggle
showing the maximum (MAX) of T1, T2, T3 or T4 readings and
its displayed time.
• Press “T1/T2 T3/T4 (T1-T2, T3-T4)” for more than 1 second to
show the maximum (MAX) of T1-T2 or T3-T4 reading and its
displayed time on the secondary display.
• The minimum (MIN) or average (AVG) reading can be
displayed in the similar way.
• Press “MAX/MIN” for more than 1 second or “ ” button
for more than 1 second to exit MIN/MAX mode.
5. Using the Offset to Compensate for Probe Errors
• Use the offset option in “SETUP” to adjust temperature
readings to compensate for the errors of a specified
thermocouple.
• Plug the thermocouple into the input terminal.
• Place the thermocouple in a known stable temperature
environment (such as an ice bath or a dry well calibrator).
• Allow the readings to stabilize.
• In “SETUP”, change the offset until the primary display
reading matches the calibration temperature, see:
Set Up Instructions section, Set Up Instructions Set Up Instructions I : Setting Temperature Offset
6. Using Memory
• During logging session, the thermometer stores logged
readings in its memory. At the end of the logging session you
can view the logged readings on the display. You can also
transfer the logged readings to a PC running the optional
software, which displays the readings on an online form,
which can be printed or stored for later use.
