4. FIRST START
4.1 PREPARATION
The battery compartment is on the back of the device. The instrument operates with
4 1,5V- batteries (AA) or 4 accumulators (NiMH, NiCd).
Attention !
Check the polarity when inserting the batteries.
Incorrect polarity can destroy the electronics of the unit.
Attention !
VacuScope easy is designed for the measuring of
atmospheric pressure. Avoid measuring of other media.
This could falsify the measurement results or destroy the
electronics. Clean and dry hoses are required to ensure
proper functioning of the pressure sensors.
Attention !
Before commissioning, all hose connections must be
checked for leaks.

4.2 SWITCH DEVICE ON
The VacuScope easy is started by pressing the button.
While starting the instrument, the measuring systems zero calibration is checked.
This defines the predominant air-pressure as zero level of the device.
Achtung !
Measuring failures may appear when the device is started
under pressure, vacuum or pulsation

5.2 SCREEN
The instrument VacuScope easy has a backlit screen with a resolution of 128 x 128
pixels.
In the upper area of the menu windows, the current programme and the battery
charge status are displayed.
In the middle area are the menu items with the setting options for the respective
programmes.
The available functions are assigned to the function keys and displayed in the lower
part of the menu window.
5.3 INTERFACES
The VacuScope easy measuring device has a sensor interface (0-5V) for connecting a
temperature sensor or an external vacuum/pressure sensor.
The RS232 interface is used both to connect the air flow meter and to connect the
instrument to the computer.
The sensors, the air flow meter and the PC software are not included in the scope
of delivery of the meter and must be ordered separately.
Attention!
To ensure proper functioning of the external devices and
sensors, screw them tightly together with the meter.
