3. Press the MODE button as many times as necessary to enter REC mode. At this point, the
values on the primary and secondary displays will be identical.
4. To recall the value stored just prior to the measurement that was just stored (with tag 83),
press the °C/°F button once. The number 82 will appear briefly (for less than a second) on
the secondary display, followed by the value of the measurement stored with tag 82.
5. Press the °C/°F button again and 82 will be briefly replaced by 81, followed by the value
of the measurement stored with tag 81.
As you can see, by pressing the °C/°F button repeatedly you can recall all stored IRT
measurements in reverse chronological order (newest through oldest). By pressing the
/
button, you can recall stored IRT measurements in chronological order (oldest through
newest). However, unless you have kept track of which tags have been assigned to particular
measurements, you typically will recall readings stored long ago. For example, pressing the
/ button instead of the °C/°F button in Step 4 above would recall tag 84, followed by the
temperature associated with it. That value, and the values associated with tags 85 and 86,
would likely be irrelevant because they represent measurements made nearly 100 hundred
trigger squeezes ago.
USING THE “K” TYPE PROBE TO MEASURE TEMPERATURE
To measure the temperature of a surface using the included “K” type thermocouple probe
(or another “K” type probe):
1) Plug the two prongs of the probe into the two slots on the bottom of the IRT730K. Be sure
to insert the slightly narrower (+) prong into the slightly narrower slot, which is closer to
the rear of the unit.
2) Press the MODE button as many times as necessary to make TK appear to the left of the
secondary display.
3) Attach the end of the probe to the surface whose temperature you wish to measure.
4) Squeeze and release the measurement trigger. The temperature measured by the
thermocouple probe will appear on the secondary readout.
Unlike measurements made by the IRT, measurements made by the “K” type probe are not
stored in memory. And although the temperature measured by the IRT will simultaneously
appear on the primary readout after you release the measurement trigger, it will not be stored
in memory—because the IRT730K is not operating in REC mode.
If you allow the IRT730K’s APO function to activate with the unit operating in TK mode, when
you power the unit back on it will resume operation in TK mode.
