Select the parameter with which the alarm is to be associated from the pull
down list.
If the alarm is to have a minimum limit then place a tick in the Min control and
type the required value in the box next to it. Do the same for a maximum limit.
9.3 Changing the Recording Method
By default, the MICROTHERM will continue to record information for as long as it
is switched ON. This means that due to the finite size of the MICROTHERM’s
memory once full, old data will be discarded to make room for new data.
In some circumstances, it can be a requirement that the MICROTHERM
continues to record until its memory is filled and then stops.

9.4 Changing the Calculation Constants
The MICROTHERM computes several additional parameters based on readings
taken from the sensors and the values contained within certain “calculation
constants”. Depending on the actual environment being measured, it may be
necessary to modify one or more of these calculation constants in order to more
closely match the actual conditions.
