INTRODUCTORY NOTE

This publication contains operating instructions, as well as a description of the principles of operation, of

PCL12 pressure calibrator.

OMEGA has used the best care and efforts in preparing this book and believes the information in this

publication are accurate. The OMEGA products are subjected to continuous improvement, in order to pursue
the technological leadership; these improvements could require changes to the information of this book.
OMEGA reserves the right to change such information without notice.

No part of this document may be stored in a retrieval system, or transmitted in any form, electronic or
mechanical, without prior written permission of OMEGA Engineering Inc.

PCL12 units use sophisticated analogic and digital technologies. Any maintenance operation must be carried
out by qualified personnel

ONLY. We recommend to contact our technicians for any support requirements.

.
PCL12 is fully tested in conformity with the directive n°89/336/CEE Electromagnetic Compatibility. OMEGA
shall not be liable in any event, technical and publishing error or omissions, for any incidental and
consequential damages, in connection with, or arising out of the use of this book.

1 General

PCL12 is a microprocessor digital pressure gauge of new generation, its advanced analog section ensures a very high

long-term stability, and its converter A/D with 16 bits guarantee 65.000 internal divisions. This feature, together with the
0,05% accuracy class, make it an ideal laboratory instrument: the PCL12 is specifically proposed as First Line Sampling
for Metrologic Laboratories, and it's delivered together with the SIT certificate. The pressure gauge has internal batteries
with 1 year autonomy, which is also guaranteed by the AUTO-POWER-OFF function, that turns off the pressure gauge if
no pressure variation is detected within 30 minutes. The user can select different engineering units (mbar, bar, kPa,
MPa, psi), and can program different resolutions and digital filter according to the application. In order to increase the
integration level of the components, a combined traditional and SMT technology has been applied; which makes the
pressure gauge more resistant against mechanical stresses and vibrations and ensures the maximum reliability of the
electronic circuit. The display also show an analog indication bar of pressure always active also into a program-menu.

Main features:

• 1 YEAR AUTONOMY WITHOUT RECHARGE

• PROGRAMMABLE RESOLUTION

• DIGITAL FILTER

• PROGRAMMABLE MEASURE UNIT

• PEAK FUNCTION (positive and negative)

• RS232 OUTPUT (optional)

2 Operating instructions

The PCL12 LCD can be divided into 3 different areas as follow:

♦ The central area display the measured pressure value using the selected unit.
♦ The lower area display the measured value as bargraph referred to the full scale value (this is active in program

mode also).

♦ The upper area show the active function (Zero, Peak+, Peak- e Low-Bat).

2.1 Keyboard

3 keys are available to program and operate with the calibrator.

ON

Set

ZERO

ON Switch the PCL12 on. The instrument power off is automatic with a

programmable delay (see par. 2.2).

Set Press this key for 3 seconds to go in programming mode.

ZERO Zeroing the pressure displayed. It is possible to run the function only if the

displayed value is less than 10% of full scale.

ª In programming mode allows to decrease the values of the selected parameter.

Peak

Peak Activating of peak+ (press it for 1 sec.) or peak- (press it for 5 sec.). This

function display the max or min measured pressure.

© In programming mode allows to increase the values of the selected parameter.

2.2 Programming

It is possible, pressing the “SET” key for 3 seconds to activate the programming mode.
To select the next parameter and confirm the previous value, you have to press the “SET” key.
After you have run all parameters, PCL12 returns in measuring mode.

It is possible to select the measuring unit using the ª and © keys.

It is possible to modify the digital filter constant (from 0 to 99) using the ª and © keys
for instable and pulsing pressure measurements.
This function change the display conversion time; if you have to measure peaks, you
should set the constant to the minimum possible.
It is possible to change the measuring resolution (possible values are 1, 2, 5 and 10).

Set the auto power off time (from 1 to 99 minutes). The 0 value, disable the function
and the instrument will be on all time. The function begin the time counting if the
PCL12 doesn’t measure pressure changes higher than 10% f.s.
Change the RS232 serial interface communication speed (if installed).
Possible values are: 1=4800baud, 2=9600baud, 3=19200baud, 0=disable.

2.3 Power Supply

PCL12 calibrator is powered by 4 type AA 1.5V batteries. These batteries allows ≈1 Year autonomy operative life. The

“LOW BAT” message will be displayed if the batteries needs to be changed. Measured pressure will be incorrect if the
LOW BAT message is displayed.
