Measurement Alarm Function
Upper and lower limits can be set for
temperature, humidity and dew point
respectively. The unit will beep and
display ‘HI’ and ‘ALM’ when a recording
exceeds the upper limit set.
‘LO’ and ‘ALM’ will show if the reading
is below the lower limit (the unit will also
beep).
Note:
The humidity alarm is inactive
when in dew point measuring mode.
Similarly, the dew point alarm is dormant
in humidity measuring mode.
Setting Upper & Lower Alarm Limits
1. With the unit switched off, press and
hold down the ‘DP | SET’ button.
2. Then briefly press the power button to
enter the limit settings menu.
Note:
The limit settings menu will toggle through the high limit
then the low limit for the temperature, humidity and then dew point
respectively.
‘TEP’ will display onscreen for the
temperature higher and lower limit.
‘HU’ will display onscreen for the humidity
settings.
‘dP’ will display onscreen for the dew point
menus.
3. Within the limit setting, press the
rightwards arrow (‘MIN | MAX’ button) to
cycle through the digits. The selected digit
will flash.
4. Use the up and down arrows
(‘Backlight | HOLD’ and ‘DP
| SET’ buttons respectively)
to change the selected digit
value.
5. Long press the ‘MAX | MIN’
button to enter the next limit
setting (Temperature Lower
Limit).
6. Repeat steps 3-5 for the humidity and dew point limits.
‘HI’ will display onscreen for the higher limit.
‘LO’ will display onscreen for the lower limit.
7. The last limit setting is the dew point lower limit. Long pressing the
‘MAX | MIN’ button after that menu should switch off the unit.
Note:
Always set the alarm higher limit higher than its corresponding
lower limit, otherwise the settings menu will cycle back to the
temperature higher limit instead of switching off after step 7. The
alarm will still go off when the measured value exceeds the limits,
but it will be difficult to tell if it is the upper or lower limit that has been
exceeded.
