IMPORTANT RECOMMENDATIONS:
•Whenever possible keep the PCA-570 in dry environment.
•The fuse protecting the current measuring circuit, code 01.02.0277-21, is a special component. So, only
replace it with another original one, in order not to impair the accuracy of the PCA-570.
•In case of failure, contact Presys Technical Assistance.
•Being without daily use, leave it on for one hour before starting the activities.

1 - INTRODUCTION
1.1. General Description
The Advanced Pressure Calibrator PCA-570 has levels of performance only comparable to laboratory
standards, having accuracy from to 0,025 % of full scale. It allows the measurement of several pressure ranges, as
well as the measurement and generation of volt and mA signals. It is designed to offer the necessary resources in
order to facilitate the work of keeping the process instruments adjusted and calibrated.
Its construction considers the use in the field, includes items of great value as: Bag with shoulder strap
allowing freedom for hands, 5.7" display with backlight led facilitating visibility in environments with little lighting,
rechargeable battery and large memory capacity to store the values obtained allowing their transfer to the
microcomputer when necessary. Besides these, several factors can be cited constructive which aggregate quality
and efficiency to PCA-570, including predict your utilization not only in field as also in rack (Version RM –Rack
Mounting, Version DT –Desktop).
Incorporates to most modern union concepts such as adjustments and calibrations with informatics, where
the data are shared by both the instrument and the computer, giving efficiency to the treatment of information, in the
form of emission of reports and certificates, of the automated management of tasks and of the organization and
archiving of data, that is, it covers a whole context directed to the fulfillment of quality procedures, mainly related to
the ISO-9000 standard. It also has HART®communication (optional) for reading and settings parameters of field
devices that have this protocol.
Can be providing with until four pressure sockets. So, in a single calibrator, can have different ranges of
pressure, for example: vacuum, 0 to 100 psi, 0 to 1000 psi and 0 to 3000 psi, or any other combination of the ranges
available. It can also be purchased with a certain number of sensors capsules and later be added others sensors.
For adding pressure sensors beyond of available in the calibrator, there is a possibility of acquisition of external
pressure module (MPYA) that communicates with the PCA-570 via USB port.
Other optional is the high accuracy sensor that, from its numerous functions, can function as default
thermometer. So, at the same time as indicates the reference temperature, possibility the calibration of any other
temperature sensor.

The PCA-570 is providing with battery rechargeable allowing up to 10 hours of continuous use. This
autonomy is reduced according to the active functions. A charger is include that can be connected to a voltage of 100
to 240 Vac. The time for a full charge is 3 hours.
The level of battery is indicated in main screen, as shown below.

Clicking on the battery icon brings up the next screen. This screen shows the battery charge (in percent), the
current (positive value if the battery is being charged and negative otherwise), and the estimated runtime of the
instrument based on battery consumption.
Fig. 08 - Battery Status

16
The charger charges the battery at the same time as it powers the calibrator, allowing the calibrator to be
used normally while the battery is being charged.
The batteries used by the PCA-570 are Lithium Polymer (Li-Po). This rechargeable battery technology
doesn't have the undesirable memory effect characteristics of its Nickel Cadmium (Ni-Cd) predecessors.
To avoid explosion or fire, only use the battery charger supplied by Presys, don't short circuit and don't
damage the battery.
2.3. Using the PCA-570: basics functions
When turned on, the calibrator performs a self-test routine and shows the date of the last calibration. In case
of failure, an error message is displayed; restart the device and if the problem persists, call technical assistance.
After the self-test, the display starts showing the main screen as shown in the figure 06.
The main screen is divided into 6 functions:
CALIBRATOR –selects input / output functions, see section 2.4.
HART®–optional module, allows communication with devices that have HART® protocol, see section 2.5.
SETTINGS –general instrument settings, see section 3.
TASKS –executa calibrações automaticamente, ver seção 2.7.
DATA LOGGER –records measurements over time, making it possible to view them in graph or table, see section
2.6.
HELP DESK –has videos made by PRESYS to assist in the use of the calibrator and can also store videos and
documents made by the user, see section 2.9.
