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
