3.6.1 VIEW LOGGED DATA Page
This page allows access to the previous measurement results made by the instrument.
A rolling total of a maximum of 150 samples can be logged, which represents a
measurement history of 150 x (measurement time) in minutes. Sample 1 represents
the most recent measurement taken. After 150 measurements have been logged, the
oldest measurement will be deleted and replaced as each new measurement is logged.
Caution: Changing the moisture value, e.g. from dew point to moisture, will
reset all the logged data and start a new file.
Access to each measurement sample is via the
Up

Down (

) buttons, which
may be used to scroll through each page of information. If faster scrolling is required
(to quickly move to another sample) press the
SELECT
button and the sample number
will increase by 10. When the sample number selected is greater than that acquired, or
is greater than 150, Sample 1 will be selected and displayed.
