You will use the context menu button to power the unit down.
Press the context button then the appearingOFF button.
3.2.Zeroing
The zeroing is selectable between last zeroing and
zeroing during start up
Last zeroing:
The unit will select the last zeroing of the pressure sensor.
Using this mode might have inaccurate measurement results due to temperature influences
(zero drift) and the unit will notask to perform zeroing during start up.
Zeroing during start up:
The user will be asked to perform a zeroing when this modeis selected.
The measurement accuracy is warranted once the zeroing was performed. The DM9600 will
select last zeroing in case thezeroing was not performed -> see last zeroing.
3.3.Function keys
Pre-defined function keys will appear on the upper and lower screen border – these keys will
differ depending on the screencontent.
The upper border typically displays the return and context buttons.
The lower border often displays the up and down buttons.

6. Preparation for each measurement
6.1.Power supply
The DM9600 can be operated optionally:
•With the built in Lithium-Ion battery
•With the included battery charger connected to the USB port
6.2.Automatic Auto-off function
The Auto-off function powers down the device if no key has been touchedfor 60 minutes.
During measurement and/or battery charging the Auto-off function is deactivated.

shutdown can be prevented by touching the screen.
6.3.Measuring with grid power supply / Battery charging
The device can be charged by connecting the supplied charger 90...260 V / 50/ 60Hz to
the USB port.
The device can be operated while it is charged.
The device will switch to trickle charge mode once the battery is fully charged.
6.4.Battery charge condition
The battery symbol indicates the battery capacity. The battery symbol will start to flash
every second in red once the battery reaches a remaining operation time of +/- 60
minutes (depending on device configuration). The device will shut down if the batteries
are not chargedin time to prevent a total battery discharge.
6.5.Operating temperature
Please pay attention to the allowed operating temperatures for this device.
The device will display shouldyou try and operate it whilst outside of the defined temperature
ranges.
In case the DM9600 was stored at a very coldlocation you will have to give the device time to
adapt to the warmerenvironment before powering it up, this will avoidcondensation!
The DM9600 is not operable when not within the temperature parameters. After powering up
the device will give acoustic signals during warm up.
6.6.Power up and zeroing
Touch the screen then press the green ON button
During zeroing the device willnotice if there are defectivesensors and will display an error
message if there are defectivesensors.
Repeat zeroing
The zeroing can be repeatedat and time.
