if the card has been formatted by other devices. To format the SD card, proceed as
described in chapter 6.7.1

• Switch on the instrument with the "▼ / Power" key.

• Check the date, time and log interval. Press the "▲ / Time" key for approx. 2 seconds.

The set values are displayed one after the other. You can change the date, time and
log interval as described in chapter 6.7.3

• Make sure that the decimal character is set correctly. The default decimal character is
a dot. In Europe, however, the comma is customary. If the decimal character is not set
correctly in your country, this can lead to incorrect values and complications when
reading out the memory card. You can make the setting as described under chapter

• Enable or disable the key and control sound as described in chapter 6.7.4

• Enable or disable the RS232 output as described in chapter 6.7.6

• Connect the signal line to the corresponding plugs of the measuring inputs, observing

11 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European
Parliament applies. Due to the contained pollutants, batteries must not be disposed of as
household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re­use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance
with your LOGal waste regulations.

If you have any questions, please contact PCE Instruments.
