For example
:
If the measured environment temperature is 25ºC, rela-
tive humidity is 50%, dew point is 13.8ºC, then:
Green light: when the measured surface temperature is
between 77ºF (25ºC) - 70.3ºF (21.3ºC);
Yellow light: when the measured surface temperature is
between 70.2ºF (21.2ºC) - 63.5ºF (17.5ºC);
Red light: when the measured surface temperature is
between 63.4ºF (17.4ºC) - 56.8ºF (13.8ºC).
NOTE - CONCRETE MOISTURE AND DEW POINT
It is recommended that the temperature of the surface
of the concrete should be at least 10ºF (5ºC) above the
ambient dew point temperature at the time of installation
so as to avoid condensation related issues.
BATTERY REPLACEMENT
•
When battery power is not sufficient, LCD will
display replacement with one new battery type 9V
is required.
•
Open battery cover, take the battery out of the
instrument and replace with a new 9-Volt battery,
then replace the battery cover.
