6. RECORDING CONFIGURATION
More practically, we may schematize the right procedure of use as follows:
1) Connect the External Power Supply
2) Check and eventually modify the basic settings of the instrument.
3) Select the parameters to be recorded.
4) Connect the DM-4 to the electrical system to be tested and push the
ON/OFF button
5) Evaluate the values of the parameters under test
6) If you want to record:
A) Decide what to record
B) Select MDL Setup Parameter and check if the existing parameters meet
your requirements
7) Start the recording by pressing RECORD.
7. STARTING A RECORDING
You can start a recording manually or automatically. Therefore, after setting all the
parameters and click on RECORD, the instrument will start recording:
MANUALLY: The recording will start when Instrument’s time reaches the “00” sec-
onds value after pressing RECORD.
AUTOMATICALLY: If the operator has clicked on RECORD the instrument will
remain in stand-by until the date and time previously set, then the recording will start.
If the operator has not clicked on RECORD, the recording will never start.

CAUTION
For recordings ALWAYS use the external power supply even though the
instrument allows the operator to perform a recording using internal batteries.
