Thermocouple Temperature Measurements
1. Note that the temperature range of the meter extends up to 1300
o
C (2372
o
F), however
thermocouple sensor ranges vary greatly; be sure to select a thermocouple rated for the
expected temperature measurement ranges.
2. Connect a Thermocouple Temperature sensor (not supplied) to the jack at the top of the meter
on the left
3. Switch the meter ON by pressing and holding the power button for 1.5 seconds
4. Press and hold the FUNCTION button to select the Thermocouple Temperature mode. When
the Thermocouple Temperature mode is selected, the display icon tp is briefly shown. The
thermocouple type (J or K) will be shown on the left side of the LCD. Use the Setup mode to
change the thermocouple type
5. Hold the thermocouple sensor tip in the air to be measured
6. The meter will now display thermocouple temperature on the primary (upper) LCD digits. Use
the Setup mode to change the temperature units of measure
Data Hold
To freeze a displayed reading on the LCD, momentarily press the HOLD button (the HOLD icon will
appear above the reading). To exit the Data Hold mode, press the HOLD button again.
Max-Min Reading Record
For a given measurement session, this meter can record the highest (MAX) and the lowest (MIN)
readings for later recall.
1. Press the MAX-MIN button momentarily to access this mode of operation (REC icon appears)
2. The meter is now recording the MAX and MIN readings.
3. Press the MAX-MIN button again to view the current MAX readings (MAX icon appears). The
readings on the display are now the highest readings encountered since the REC icon was
switched on (when the MAX-MIN button was first pressed).
4. Press the MAX-MIN button again to view the current MIN readings (MIN icon appears). The
readings on the display are now the lowest readings encountered since the REC icon was
switched on (when the MAX-MIN button was first pressed).
5. To exit the MAX-MIN mode, press and hold the MAX-MIN button for at least 1.5 seconds. The
meter will beep, the REC-MAX-MIN icons will switch off, the MAX-MIN memory will clear, and
the meter will return to the normal operating mode.
