3. DESCRIPTION

3.1 INTRODUCTION

VacuScope easy is a handy device for checking pulsators and measuring the vacuum

curve in milking systems with outstanding product features:

•Visualization of the vacuum courses by a graphic display during testing

•Clear operation with fixed and adjustable keys

•Several interface connections for devices and sensors

•Large memory for storing measurement data and settings

Based on a wide range of programmes the device is used in development,

maintenance and servicing of milking units.

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.

VacuScope easy Version V1.1

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.
