1 INTRODUCTION

1.1 Easy Box U1Air

This manual aims at supporting operators and maintenance personnel with set-up and

calibration of these units.

Pneumatic gauging uses air pressure to resolve measurements. For pneumatic

gauging it is necessary to convert the air pressure signal from the gauge head to an

electronic signal in order to display the measurement data for the user. The device to

do this conversion is called an Air to Electronic Converter, thus A to E or A/E Converter

for short.

The Marposs Easy Boxes U1Air, U3Air, U4Air have been designed to provide accurate

measurement results from a variety of air gauge devices and contain one, three, four

A/E Converters respectively. They have been built to be used in harsh environments.

The Easy Box interface boxes allow easy and economical management via USB port

of air gauges, and can be used with the MARPOSS gauge computers Nemo, Merlin,

Merlin Plus, E9066, or with any commercial Personal Computer.

2.1 USB output

Both Easy Box™ power supply and transmission to a PC of the measuring values of

the connected transducers are realized through the USB port. A single USB cable is

therefore required for both functions.

2.2 Data triggering

The Easy Box™ continuously provides to the PC via USB port the values of the sensors

connected to the box. Whenever a data trigger is necessary, it can be made in two

ways:

• With the external signal of a footswitch connected to the Easy Box™.

• With a data request from the host PC.

2.3 Software packages to manage Easy Box

• MARPOSS DLL drivers library for Windows®operating systems, allowing to interface

Easy Boxes with any Windows 98®(or higher release) compatible application

program with minimum software programming skills.

• Easy AcquisitionTM software package for data acquisition and SPC on Excel®

worksheets: a complete and easy to operate software package to import data,

program measurements, perform data collection and SPC analysis and reporting.

• Quick SPC™ process and quality control software for Windows®, a suite of software

Products designed to comply with any requirement ranging from simple

measurement acquisition to complex gauging applications.

3 U1AIR / U3AIR / U4AIR APPLICATION RANGE

The MARPOSS and/or non-MARPOSS air gauges, with speciﬁcations inside the

blue area of the diagram, can be easily and immediately connected to these models.

The parameters to be considered are the following:

• Air supply pressure.

• Number of air gauge jets.

• Diameter of air gauge jets.

• “Mid-range gap”, as to the difference between the mid-tolerance diameter of the part

to be measured and the distance between the air gauge jets.

3.1 Example of measurement with air-plug

• Air supply pressure: 3 bar ± 0.1.

• Number of jets: 2.

• Diameter of jets: 2mm (.0787”).

• Diameter of the part to be measured = 10 mm ± 0.030 (.3937” ± .0012”).

• Mid tolerance diameter = 10 mm (.3937”).

• Distance between the jets D = 9.90 mm (.3898”).

We obtain:

• “Mid tolerance gap”: (10 - 9.90) = 0.10 mm = 100 μm.

As shown in the diagram the intersection between the value of the “mid-range gap”,

100 μm (.0039”), and the diameter of the jet, 2 mm (.0787”), stays inside the blue area:

the application can be therefore realized.

- 9 -

At air treatment and ﬁltering unit input

• Air supply pressure 5 - 8 bar

• Air ﬁltering 40 μm

At air treatment and ﬁltering unit output (a/e converter input)

• Air operating pressure 3 ± 0,1 bar

Air must be dry and oil-free, passed through a coalescing ﬁlter with

following capability

• Solid content 5 μm

• Dew-point 2- 5°

• Oiled content 0,01 mg/m3

At a/e converter output (air gauge input)

• Air working pressure 1,8 ± 0,1 bar

5 INSTALLATION

5.1 Sensitivity adjustment

• Connect the Easy Box to the electronic measuring display unit.

• Connect the air gauge to the Easy Box. Make sure the pipe is free from particles.

The max. pipe length can be 1,5 m.

• Connect the air supply pipe to the air treatment unit and this to the Easy Box.

• Turn on the air supply switch.

• Adjust the pressure at 3 bar.

• Perform the sensitivity adjustment.

For this adjustment both MIN and MAX masters are required.

The difference between the two masters has to be calculated (absolute value):

d = MAX master – MIN master

Example:

Upper tolerance limit = + 20

Lower tolerance limit = 0

and

MAX master = + 21

MIN master = - 1

It results then:

d= Max - Min = 21 - (-1) = 22

d/2= ± 11

By proper adjustment the working range of the A/E converter must be symmetrical

around zero.

According to the above example the result is

5.2 Adjustment procedure for inner diameter measurement

• Specify the Easy Box UxAir in the hardware conﬁguration of your display instrument

(E9066, Merlin, Merlin plus, Nemo, …..).

• Go to the transducer settings and set the sign inversion to YES.

• Unlock the lock nuts (3) and carefully turn the Sensitivity (1) and Zeroing knobs (2)

clockwise until they close. Use a “light touch” (*).

• Open the Sensitivity knob, 6 turns counter clockwise. Open the Zeroing knob, 1/4

turn counter clockwise.

• Put the gauge plug into the MAX master and adjust the Sensitivity Knob until the

display reads the Upper Limit (for example +11 μm, half of the range, see above).

• Next, using the MIN master, adjust the Zero Knob until the display reads the Lower

Limit (for example -11 μm, half of the range, see above).

• Repeat the two previous steps as many times as needed until the readings are within

25% of the total spread between the Upper and Lower Limits.

• Tighten the lock nuts (3) for the Sensitivity and Zero knobs. Check the setup

again to make sure that it has not changed.

(*) NOTE: Tightening strongly the Sensitivity or Zero offset adjustment

knobs may result in damaging the nozzle of the knob.

5.3 Adjustment procedure for outside diameter measurement

• Specify the Easy Box UxAir in the hardware conﬁguration of your display instrument

(E9066, Merlin, Merlin plus, Nemo, …..).

• Go to the transducer settings and set the sign inversion to YES.

• Unlock the lock nuts (3) and carefully turn the Sensitivity (1) and Zeroing knobs (2)

clockwise until they close. Use a “light touch” (*).

• Open the Sensitivity knob, 6 turns counter clockwise. Open the Zeroing knob, 1/4

turn counter clockwise.

• Put the gauge device onto the MIN master and adjust the Sensitivity Knob (upper

knob) until the display reads the Upper Limit (for example +11 μm, half of the range,

see above).

• Next, using the MAX master, adjust the Zero Knob (lower Knob) until the display

reads the Lower Limit (for example -11 μm, half of the range, see above).

• Repeat the two previous steps as many times as needed until the readings are within

25% of the total spread between the Upper and Lower Limits.

• Tighten the lock nuts (3) for the sensitivity and zero knobs. Check the setup again

to make sure that it has not changed.

(*) NOTE: Tightening strongly the Sensitivity or Zero offset adjustment

knobs may result in damaging the nozzle of the knob.
