TEMPERATURE MEASUREMENT
1. Insert the probe plug into the socket at the top
of the meter. The plug and sockets are keyed
with a small and large pin. Make certain that the
plug is inserted correctly. Do not insert the plug
incorrectly and force the connection.
2. Press the button to turn the meter on.
3. Press the button to select °F or °C.
4. Place the probe in contact with the material to
be measured and read the temperature on
the display.
5. Press the button again to turn the meter
off. To conserve battery life, always turn off the
meter when not in use.
After 20 minutes, the meter will automatically turn
off to preserve battery life. To disable this feature,
see the “Automatic Shutoff Disable/Enable”
section.
DATA HOLD FUNCTION
To “freeze” the display at the current temperature
reading, press and release the
button
(“HOLD” will appear at the top of the display).
Note: While in this mode, pressing the button will have no
affect and will not change the display.
Press and release the button a second time
to return to current temperature display (“HOLD”
will no longer appear on the display).
MEMORY RECORD MODE
Press the
button to activate the Record mode
and start the timer (“REC” will appear on the display).
While in the Record mode, the meter will record
the minimum and maximum temperature readings
achieved along with the relative time (count-up time)
that the minimum and maximum were achieved.
Note: While in this mode, pressing the button will have no
affect and will not change the display.
Note: If the Automatic Shutoff feature has not been
disabled, the meter will turn off automatically after
20 minutes. For long term monitoring, disable the
Automatic Shutoff feature. (See the “Automatic
Shutoff Disable” section.).
Press and hold the button for 3 seconds to
exit the Record mode (“REC” will no longer appear
on the display).
The minimum and maximum temperature recordings
are automatically cleared once the Record mode
has been exited.
MEMORY RECALL
1. While in the Record mode, press the
button to display the maximum temperature and
relative time (count-up time) that the maximum
temperature was achieved. (“MAX” will appear
on the display.)
2. Press the button a second time to display
the minimum temperature and relative time
(count-up time) that the minimum temperature
was achieved. (“MIN” will appear on the display.)
3. Press the button a third time to return to
the current temperature display and relative
time (count-up time).
AUTOMATIC SHUTOFF DISABLE
The Automatic Shutoff feature will turn the meter
off after 20 minutes to preserve battery life. This
feature is automatically enabled each time the
meter is powered on, regardless of whether the
feature was disabled previously.
To disable the Automatic Shutoff feature:
While the meter is turned off, press and hold the
button, then press and release the
button. Continue to press and hold the
button while the meter turns on. Once “n” appears
on the display (indicating that the Automatic Shutoff
feature has been disabled), release the
button. The meter will then display the current
temperature.
With the Automatic Shutoff feature disabled,
the meter will remain on until the
button is
pressed, or until the battery is fully drained.
RELATIVE MEASUREMENT MODE
Press and hold the
button for 3 seconds to
activate the relative measurement mode (“REL” will
appear on the display. When the relative measure-
ment mode is activated, the display will show the
“relative zero” based on the temperature that was
being measured when the mode was entered. The
display will then indicate the temperature difference
from the “relative zero” value.
Example--
If the temperature being measured is 25.0 °C
when the relative measurement mode is entered,
the meter will set 25.0 °C as the “relative zero”
and the display will show 0.0 °C as long as the
temperature being measured is 25.0 °C. If the
temperature rises to 27.5 °C, the display will show
2.5 °C. If the temperature falls to 20.0 °C, the
display will show -5.0 °C.
Note: While in this mode, pressing the button will have no
affect and will not change the display.
To exit the relative measurement mode, press
and release the
button (“REL” will no longer
appear on the display.)
MEMORY RECORD - RELATIVE MEASUREMENT
While in the relative measurement mode, press the
button to activate the Record mode and start
the timer (“REC” will appear on the display).
While in the Record mode during relative
measurement, the meter will record the minimum
and maximum temperature difference from the
“relative zero” value achieved along with the
relative time (count-up time) that the minimum and
maximum were achieved.
Note: If the Automatic Shutoff feature has not been
disabled, the meter will turn off automatically after
20 minutes. For long term monitoring, disable the
Automatic Shutoff feature. (See the “Automatic
Shutoff Disable/Enable” section.).
Press and hold the button for 3 seconds to
exit the Record mode (“REC” will no longer appear
on the display).
The minimum and maximum temperature recordings
are automatically cleared once the Record mode
has been exited.
MEMORY RECALL - RELATIVE MEASUREMENT
1. While in the Record mode during relative
measurement, press the
button to display
the maximum temperature difference and
relative time (count-up time) that the maximum
temperature difference was achieved. (“MAX”
will appear on the display.)
2. Press the button a second time to
display the minimum temperature difference and
relative time (count-up time) that the minimum
temperature difference was achieved. (“MIN” will
appear on the display.)
3. Press the button a third time to return to
the current relative temperature display and
relative time (count-up time).
COUNT-UP TIMER
The count-up timer feature offers a relative time
reference while taking temperature measurements.
To turn on the count-up timer and begin timing,
press the
button.
To stop timing and turn off the count-up timer,
press the
button a second time.
BACKLIGHT
Press the
button to turn on the display
backlight when in dim or dark conditions. The
light will automatically turn of after 30 seconds to
preserve battery life.
THERMOCOUPLES
The meter is supplied with a Type-K thermocouple
but is also able to accept Type-J and Type-T
thermocouples.
Thermocouple range:
Type-J = -328 to 940°F/-200 to 760°C
Type-T = -328 to 730°F/-200 to 390°C
To change the thermocouple type:
1. While the meter is turned off, press and hold
the
button, then press and release the
button. Continue to press and hold the
button while the meter turns on. Once the
display appears with only “K”, “J”, or “T”, release
the
button.
2. Press the button to select the desired
thermocouple type (K, J, or T).
3. With the desired thermocouple type on the
display, press the
button. “S” will
momentarily appear on the display indicating
that the setting has been saved and the meter
will then display the current temperature.
