DISPLAY AND FUNCTIONS
GENERAL OPERATION
This Thermo-Hygrometer will measure / display indoor temperature
( the air temperature measured by the sensor built inside the unit )
or outdoor temperature ( the air temperature measured by the
detachable external sensor probe ) and indoor relative humidity
( the relative humidity measured by the sensor built inside the unit ).
It can be set to display the indoor/outdoor maximum or minimum
temperature and indoor relative humidity recorded.
Note:
When the outdoor temperature is over the measuring range, flashing
digit ‘-50’(
°C) / ‘-58’(°F) appears on the display ( below –50°C /
-58°F ) or ‘70’(
°C) / ‘158’(°F) appears on the display ( above +
70°C / + 158°F )
When the indoor temperature is over the operating range, it fades
out on the display ( below 0°C / + 32°F ) or blacks out on the
display ( above + 50°C / + 122°F )
This Thermo-Hygrometer will continue to record the indoor /
outdoor maximum, indoor / outdoor minimum temperature and
humidity changes, whether displaying current, maximum or
minimum temperature readings.
