3.Button
1. Press to turn the thermometer on or off.
2. Press "MAN/MIX" to step through the maximum, minimum, and average readings.
To exit the MAN/MIX/AVG mode, press the "MAN/MIX" button for 2 seconds to return to
normal operation.
3. Press "P/V/F" to show the air velocity, press "P/V/F" secondly to show the high and
length of a rectangular or the diameter circular duct, press "P/V/F" thirdly to show the air
flow, press "P/V/F" to show differential pressure again.
4. Press "Hold/Zero" to freeze or unfreeze the displayed readings. Press "Hold/Zero"
button and hold 2 seconds to zero out the display.
5. Press "Save/Clear" button to store sample data. Or press "Save/Clear" button to

6. Press "Setup " button to turn on the backlight. Press it again to turn off the
backlight. Press "Setup " button for 3 seconds to start or exit Setup. (See "Changing
Setup Options.")
7. Press "Unit " to changes the temperature units. In Setup mode, press "Unit " to
scroll to the Setup option you want to change or press "Unit " to increase the displayed
setting. In Recall mode, press "Unit " to select the desired sample number.
8. Press "Unit " to Changes secondly showing number units. In Setup mode, press
"Unit " to scroll to the Setup option you want to change or press "Unit " to increase
the displayed setting. In Recall mode, press "Unit " to select the desired sample
number.
9. Press "Avg/Rec" button and hold 2 seconds to enter Recall mode. In Recall mode,
press "Avg/Rec" to calculate the sample data. In Setup mode, press "Avg/Rec" button
to enter a Setup option. Press "Avg/Rec" again to store the displayed setting in memory.
