8 Important notes for using meM-LOG-SE
•
The device is only suitable for extra-low voltages – please observe the relevant regulations! For reasons relating to
EMC, the device must only be operated with housing closed. ESD voltages at open lines may cause malfunction
during operation. Only use an electrically isolated power supply unit (with CE).
•
For cleaning the device use water and mild detergent only. The device is designed to be maintenance-free.
•
At the 37- and 15-pole Sub-D
socket
signal cables are connected – use shielded cables only. For best possible inter-
ference suppression connect shield at one end only. Close open inputs if necessary.
•
The device ground and the chassis are electrically connected to the chassis of the PC, which is usually also con-
nected to ground. Be sure to avoid ground loops, since they will cause measuring errors!
•
PCs (notebooks), which are not grounded often produce high potentials to earth at the USB socket, so that safe
operation cannot be guaranteed. In this case connect the data logger to earth.
•
The Gain is adjusted to even values. Therefore only 4000 (with 12 Bit) values of the full range of the converter are
used. As a result, the measuring ranges are slightly larger (
±
5.12V) than the indicated measuring ranges, so that
overranges can be recognized. The AD converter of
meM-LOG-SE
has a code noise of up to
±
1 LSB.
•
If the device has not been used for longer (>3 months), the integrated accumulator must be recharged .
•
The device must not be used for safety-relevant tasks. With the use of the product the customer becomes manufac-
turer by law and is therefore completely responsible for the proper installation and use of the product. In the case of
improper use and/or unauthorized interference our warranty ceases and any warranty claim is excluded.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly
disposed according to the WEEE directive or can be returned to bmcm at your own expense.

* The total sampling rate is the sum of the sampling rates of the individual used channels
(e.g. 5 channels à 100Hz => 500Hz total sam-
pling rate). The values for accuracy always relate to the respective measuring range. Errors might add at worst.
