External supply: 12 V battery or 12 V DC power supply unit is sufficient

to keep the instrument operational for long term data logging, but will

not recharge the battery.

Charging: 15 to 18 V DC battery or AC adaptor is required to charge the instrument.

Measurements or recordings parallel to the charging procedure are technically pos-

sible, but not specified, therefore not to be recommended.

5 How to Measure and Data-Log

5.1 "Live"-Measurement

You have the choice of two basic measurement modes: You can either apply the

conventional method which involves switching the unit on and reading the display.

Or you prefer to have the measurement values of all four channels (those of the

three field axis plus one further measured variable) logged onto the SD-card. To ac-

tivate this function, please switch the Power-button to "Log" for a short time until

the status-LED turns green. Then switch it back to "On".
