Resetting the Min/Max Values
The UTREL30-WiFi tracks the minimum and maximum temperatures since it started
logging, separately for each channel, and displays them below the last recorded
temperature.
These values can be reset any time while the unit is
recording (but not once the unit has stopped).
Note: Since each channel tracks these values
independently, you must perform the
procedure separately for each channel. Only
the values for the channel shown when you
start the procedure will be reset.
To reset the values, follow this procedure:
1. Press and hold the
REVIEW
/MARK
button.
2. After 1 second the number values alternate
with dashes, after 4 seconds, the dashes
remain on.
3. Release the buttons within 2 seconds. The
values will be reset and the dashes remain on
screen.
The values will not be reset, and the currently stored min/max values will be retained if
l
you keep holding the button for more than 2 seconds after the dashes no longer
blink; or
l
you release the button within the initial 4 second period after the initial press.
In these cases, the display keeps showing the normal recording screen.
If desired, switch to the other channel and repeat the procedure.
The logger will now track new min/max values for each channel that was reset. A
min/max reset mark will be recorded in the logged data. As soon as the next reading is
taken, both minimum and maximum values will be shown again.
You will be able to see on the PDF and in the summary in LogTag
®
Analyzer when the
min/max values were cleared, but you will not be able to review previous min/max
values on screen once they have been cleared.
