Data logger operating manual

9.1. Battery change
If “LO bAtt” appears in the upper row of the display, then the batteries need to
be changed.
No data can be recorded while batteries are being changed. If data
recording is running, pause it and ensure that the data logger is in
operating mode M1 or M2 before changing the batteries.
To replace the batteries, open the battery compartment, remove the used batter-
ies and then insert new batteries, while observing the correct poles.
The time is maintained for at least a minute during battery change,
even when batteries are not inserted.
Only use appropriate batteries which comply with the technical data. Other types
of batteries can cause operating errors. Do not use rechargeable batteries !
Do not dispose of used batteries in the household rubbish or throw them in the
fire; instead, dispose of them according to the relevant legal requirements.
9.2. Deleting measured data
The detected measured data are permanently saved in the internal Flash
memory. Even when resetting the device to factory settings or when there are
no batteries in the device, the measurement data remains in the memory and is
not deleted.
Saved data can only be deleted via the SmartGraph3 software as a whole and
not individually.
The deletion process takes approx. 2
minutes. During this time, the following
messages appears on the display:
“FOMA FLSH xxx %”.
During the entire deleting period, access
to the device is not possible and it does
not respond to requests from the Smart-
Graph3 software.
After memory has been completely
deleted, “FOMA FLSH 100 %” is shown
on the display. Afterwards, the display returns to normal operation.
Further detailed information about using the software is provided in the
software manual which you can open from the help function of the Smart-
Graph software.
Display for deleting measured data. In the
display, 6 % of the data have been
deleted so far.
9.3. Positioning for mobile use
For mobile measured value recording, the data logger can be positioned at any
site. Observe the permissible ambient conditions for operation (see technical
data). Due to its compact dimensions, the data logger can be hidden for non-in-
trusive applications.
9.4. Mounting on a wall
For stationary data detection, the data logger can also be mounted on a wall
or a similar holding device. A mount track is included in the scope of supply for
fastening.
For network operation, wall mounting is absolutely necessary.
Additional information about network operation is provided
in chapter 6.2.2.
9.5. Moving to another site
Especially when moving from cold to warm ambient conditions, e.g. when
moving into a heated room after storage in a car over night, depending on
humidity in the room, condensation may form on the printed circuit board.
This physical trait can lead to false measured values. Unfortunately, it is neces -
sary for the construction and cannot be prevented in any measuring devices. In
these cases, please wait approx. 5 minutes until the measuring device has
“acclimatised” before starting to measure.
