INTRODUCTION

Ref R is a digital manometer controlled by a microprocessor.
It is a practical and economical solution to perform measures
of pressure and temperature while maintaining a good
accuracy and reliability.
The Ref R has set the DATA LOGGER function which allows
you to store up to 60,000 measurement points in regular time
steps from 1s to 10 hours per point.
The measurement system consists of an analog section
particularly stable and an A /D converter with 16-bit
resolution (65000 divisions).
To increase the level of integration of components has been
used a mixed technology, traditional and SMT, that makes the
indicator resistant to vibration and mechanical stress as well
as ensuring the reliability of the circuit.
2 Internal batteries (size AAA - 1.5V) provide a range of 1
year, thanks to the function of AUTO POWER OFF which
occurs when there are no changes in the measure for a time
of 30 minutes.
By selecting the reading of the TEMPERATURE can be
displayed on the display the temperature of the fluid in contact
with the pressure sensor

The indicator has a setting menu which allows to choose the
resolution and the digital filter according to the measurement to
be calculated.

Main characteristics:

• PROGRAMMABLE RESOLUTION

• PROGRAMMABLE DIGITAL FILTER

• PROGRAMMABLE BAUD RATE

• ZERO FUNCTION

• PEAK FUNCTION (positive and negative)

• RS232C SERIAL OUTPUT (on request)

RECOMMENDED MECHANICAL MOUNTING

WARNING

During the gauge mounting DO NOT force the

case but tight with the wrench.

O-RING tight for pressures <1000bar USIT RING 12.70X18X1.5

for pressures <1000bar

Double cone tight: pressures ≥1000bar

INSTALLATION

Installation shall be done by authorized personnel only; for

a fast installation follows the instructions listed below:

• PRELIMINARY CHECKS

• SWITCH ON - check the display during the test phase

• PROGRAMMING (digital filter, resolution, etc.)

INSTRUMENT SWITCHING ON

When instrument switches on, it performs the display check with
the switching on of all the segments, then it shows the release for
a few second and finally the pressure measured; in case a series
of “L” (negative full scale overload) or a series of "U" (positive full
scale overload) appears, please act in order to bring the pressure
back within its full scale value.

PROGRAMMING

All the functions can be recalled through the following

SETTING MENU

1) Digital Filter

2) Resolution

3) Power Off Time

4) DataLogger Parameters

5) Baud Rate RS232

KEYS DESCRIPTION

Key with three functions:

1) ON to switch on the indicator.

2) SET to enter into the configuration menu (keep the key

pressed for approx. 3 seconds).

3) During the measurement, if pressed for 5 seconds it
performs the manual indicator switching (OFF).

Key with 3 functions:

1) During the measurement it performs the display ZERO
(max 50% FS);

2) If kept pressed for about 5 sec. it deactivates the ZERO
function displaying the offset of the manometer.

3) Inside the setting menu it decreases () the value on the
display.

Key with 4 functions:

1) During the measurement, if pressed for a second, it
activates the PEAK+ function, (it displays the highest pressure
detected after having activated the function).

2) During the measurement, if pressed for 5 sec., it activates
the PEAK- function (it displays the lowest pressure detected
after having activated the function).

3) During the measurement, if pressed for 8 sec., it activates
the temperature measure.

4) Inside the setting menu increases () the value on the
display.

To enter into setting menu press the SET key (approx.3sec.) until
the first parameter appears on display (FL digital filter). Press
SET either to go to next parameters or to exit from setting menu.
Press SET after the last parameter both to save data and to
come back to measurement mode. New set values become
active at the exit of setting menu.

SETTING MENU

This parameter changes the effect of the
Digital Filter. By increasing the XX value,
filter effect increases, allowing the user to
detect the average value of unsteady or
pulsating pressures. Selectable values go
from 0 to 99.
This function also acts on display conversion
speed, therefore if the operator wants to detect
the peaks, it is recommendable to decrease at
the minimum the filter effect.

RESOLUTION
In this step it is possible to set the resolution
used to display the pressure, the selectable
values are: 1, 2, 5 and 10.

AUTO-POWER OFF TIME
It set the time in minutes (from 1 up to 30)
before the Auto-power off function activates, in
case of constant measurement; by setting
0(zero) the instrument never switches off.
Auto power off function starts working if the
indicator does not detect changes higher than
±10% of set pressure.

Define the time between 2 point acquisition.
The format of the field t1 is the following:

Example:

0.00.05 : t1 = 5s

0.01.15 : t1 = 1min e 15s

2.00.00 : t1 = 2hours

Define how long the cycle will last.
The format of the field t2 is the following:

Example:

001.00 : t2 = 1 hour

000.30 : t2 = 30 minutes

Enable/Disable the temperate acquisition.
With the temperature acquisition the maximum
number of points that can be stored is limited to

The DataLogger can store up to 60,000 measurement points
(30.000 if also the temperature is stored) in steps ranging from
1s to 10 hours according to the parameter t1 defined in the
Setting Menu. Cycle length is determined by the parameter t2
always defined in the Setting Menu.
Data stored during the last Datalogging are permanently saved in
nonvolatile memory within the gauge so that the measures will
always be accessible until the creation of a new cycle of
measurement
Note:
The functionality of the DataLogger is fully manageable from the
PC using the AnalyzerLight software through which you can:

• View the status of the current cycle.

• Download all the measurements.

• Save all measurements on a file.

• Display the test curve.

• Print the test curve.

• Export to Microsoft Excel the test curve.

• Make the START / STOP of a cycle.

• Set the parameters t1 and t2 and temperature
