Log Methods
Selecting the LOG mode not only identifies the way in which data is stored in instrument
memory but also governs the way the RUN mode works. Four possible choices in the LOG
mode are available. Each is explained below.
Option
Description
1. NONE Selecting None means that no logging action takes place at all. When the
instrument is in the RUN mode, you can only display readings.
2. AUTO When you select and configure the AUTO method, the RUN mode functions
automatically once an action is initiated. You choose an automatic logging rate
between 1 second and 999 minutes, type a tag* identifier, and start the instrument.
You initiate automatic sampling by either pressing the LOG key on the
probe or the ENTER key on the instrument. From that point on, the instrument
automatically logs the reading of the sample at the end of each countdown
and continues to do so until the battery goes low or you press the EXIT
key.
