Data Recording
Record Time: Use F3 to set the logging duration: 1, 5, 10, 12, 24, or 48 hours.
Data logging sessions will automatically end after the programmed recording
time. You can manually stop a recording session by selecting Stop in the Re-
cording menu.
For long logging sessions, it is recommended that you connect the RH600 to
a power source to ensure that it does not switch off during the session be-
cause of a low battery condition.
The APO (automatic power off) function is disabled while the RH600 is log-
ging. When logging stops the APO function is again active. The APO utility is
configured in the Settings programming menu (Section 7).

8.3 Start/Stop Data Log Recording

On the Recording page, as covered in section 8.2, scroll to the Start/Stop op-
tion and press F3 to start or stop the Data logger. When the logger is record-
ing, a red circle is shown at the top of the screen . The logger will
automatically stop when the programmed logging time has elapsed; the red
circle will switch off. Note that you can manually stop the recording session at
any time by selecting Stop in the Recording menu.

8.4 Data Recording Using the Data Hold Function

As mentioned in Section 2.3, Button Descriptions, and Section 6.4, Data Hold,
you can freeze displayed readings by pressing F2 (HOLD). The word HOLD
(in red) then appears on the display, indicating that the Data Hold function is
engaged, and the readings are frozen.
If you press F3 , in the Data Hold mode, the held readings will be stored to
a file named Hold and Save, in the internal flash drive. These readings can be
viewed on the RH600 display (graphically and as text) and can be down-
loaded to PC, as explained in Sections 8.6 and 8.8, below. Press F1 to exit
the Data Hold mode.

8.5 Viewing Recorded Data on the RH600 Display

To view readings saved by the Data Logger or the Data Hold function, scroll to
the View Data File option in the Recording menu and press F3. The list of
stored files will appear as shown in Figure 8.2. Use the up and down arrow
buttons to scroll through the files. Data logger files are named using the date
and time of recording – there is a data log file for each logging session. All
