Reducing the volume of data

When making extensive recordings it is recommended that all sensors that are

not required be “turned off”. This prevents unrequired measurement parameters

from being saved.

• Under Basic settings turn "off" all unused sensor groups (see next section).

• To turn off individual sensors within one sensor group proceed as follows: Set

the cut-in condition such that they are not activated during the planned re-

cording (e.g. > 200 °C) (see next section).

Conditional recording of measurement parameters (limits)

If for example, you require only to record temperatures above 5°C and less than

20 °C, use the following procedure:

Setting the alarm limit

The logger can display an alarm if a certain measurement parameter drops below

or exceeds a certain value. When the alarm condition occurs the red LED flashes

once per second until the data recording is stopped.

Inputting the alarm condition is carried out in the same way as setting the cut-in

conditions (see section Conditional recording of measurement parameters).

In the Alarm Limit, Limit L1 and Limit L2 columns enter the

alarm conditions.

The alarm limits can be displayed in Viewer.

• In the columns Record Limit, Limit

L1 and Limit L2 enter the cut-in condi-

tions for the sensor.

• Return to the Basic settings with

and click Write basic set-

tings. The limits will only be trans-

ferred to the logger with Write basic

settings

• Activate Limits active

and the cor-

responding temperature sensor

• The Limits tab opens.

The logger only records measurement

parameters from the sensor T(p) above

5°C and less than 20 °C
