7-1. Function overview
Set the alarm for the abnormal value to inform you when
measured, with the
『
H
』
or
『
L
』
indicator blinking in the
LCD.
Reference
If the alarm has been set for 30.0 °C / 50.0 °F (50.0 %)
as the upper limit and the measured value is 30.0 °C /
50.0 °F (50.0 %) or higher, the
『
H
』
indicator will appear
and start blinking. If the current value becomes 29.5 °C
/ 49.5 °F (49.0 %) or lower,
『
H
』
will go out.
Also, if the same value has been set as the lower limit
and the measured value is 30.0 °C / 50.0 °F (50.0 %)
or lower, the
『
L
』
indicator will appear and start blinking.
If the current value becomes 30.5 °C / 50.5 °F (51.0 %)
or higher,
『
L
』
will go out. (The hysteresis is 0.5°C or 0.5
°F in temperature and is 1.0% RH in humidity.)
