Use the ud buttons to select the menu. Press the Enter button to select the

When recording is enabled, measurements are stored in memory at the set pe-
riod. The data is highly compressed digitally to achieve a high storage density.
This is done by storing data in blocks, headed by product and sensor identifica-
tion and time information that applies to subsequent measurements up to the
start of the next data block. A new data block is started when the thermo-hy-
grometer is powered on, when record setting parameters are changed, and when
data is printed or written to a file. A new data block is also started when the
date or time is set, when the date changes, and at regular intervals depending on
the record period. Thus data blocks may contain various quantities of
measurements.
CAUTION: When data recording memory fills up, the earliest block of
data is automatically discarded so recording of the most recent data can
continue.
