1.1 Special Conditions for Safe Use
Use the calibrator only as described in this technical manual.
The battery should only be charged in a safe area, using the supplied charger. To
prevent explosion or fire, use only the battery BT507-IS and the charger CG507-IS
specified by Presys.
Never replace the battery in hazardous areas.
Do not use the serial communication port in hazardous atmospheres.
The calibrator aluminum metal enclosure is protected by a leather bag (BC507-IS)
that should always be used when in hazardous areas.
The intrinsic safety of the instrument is only valid for the connections shown in this
manual, respecting the intrinsically safe input and output parameters. The entity
parameters and connections are illustrated in the items "3.4, 3.5 and 3.6 -
Operation".
To prevent damage to the instrument and validate the Ex certification, never apply
a voltage greater than 30 V between the terminals and the metal enclosure of the
instrument.
Never open the calibrator enclosure. The opening of the enclosure may void the Ex
certification.
Do not use tools that may cause spark in the calibrator; this practice can cause
explosion.
Never do any maintenance on calibrator; the components used are specified and
cannot be changed.
Never use the Calibrator in an area close to explosive dust.

2 - Introduction
2.1. General Description
The PC-507-IS is a pressure calibrator designed to be used in hazardous areas where
there is presence of flammable or explosive vapors. It is an instrument of small dimensions,
compact; it operates with rechargeable battery and comes with a leather carrying case. Its
technical features indicate performance levels comparable only to laboratory standards; it
presents accuracy of 0.025% of full scale. Can be provided with one, two, three or four pressure
sensors. Thus, in a single calibrator may be have different pressure ranges, e.g. vacuum, 0 to
100 psi, 0 to 1000 psi and 0 to 3,000 psi, or any combination of available ranges. The calibrator
may be purchased with a certain number of sensors, which may be later increased. Designed
for field use, it contains useful items as a high contrast LCD for a better viewing in poor lighting
conditions, besides presenting measured and generated signals with large digits so that they
can be seen far away, rechargeable battery and large memory capacity to store the values
making it possible to transfer them to the PC, when necessary. Besides these, may be
mentioned several other constructive factors which add to the calibrator quality and efficiency,
including providing its use not only in the field as workbench.
It incorporates the most modern concepts of calibration via computer, where data
are shared between instrument and computer, improving efficiency in handling information
through report and certificate issues, automatic tasks management, data organization and
storage, for an overall coverage of quality procedure requirements, especially those related to
ISO 9000.
When connected to a computer it can be used for on-line data acquisition (only in safe
area).

3.2. Battery and Charger
The calibrator is supplied with rechargeable battery which enables up to 27
hours of continuous use, or less, especially when the 4-20 mA output is used. A
charger is provided, which can be connected to 110 or 220 Vac. Attention to change
the selection key 110-220 Vac in the charger. Time required for a full charge is 14
hours. When the display indicates LOW BAT, the battery level is low and it is
necessary to recharge it. It is possible to use the calibrator while charging the battery,
however, to increase the load speed is advisable to leave the calibrator off.
The battery should only be charged in a safe area. They should be used only
charger (CG507-IS) and the battery (BT507-IS) specified by Presys, otherwise
there is risk of fire or explosion
The batteries used by the calibrator are made of Nickel-Metal Hydride (Ni -
MH). This new technology for rechargeable batteries does not have the undesirable
characteristics of memory effect and environmental pollution as their preceding
batteries made of Nickel Cadmium (Ni-Cd).

3.3. Using the Calibrator: Basic Functions
When the calibrator is powered on, the display shows:
OFF ON
If the user does not select ON and press ENTER within 12 seconds, the
instrument will turn itself off. The purpose is to save battery from turning the
instrument on accidentally while in the bag.
When ON is confirmed, the calibrator goes through a self-test routine and
shows the last adjustment date and the value of the battery voltage; in case of failure,
it displays a message to indicate RAM error or E2PROM error; if that occurs, the
instrument should be sent for repair.
After the self-test, the display shows the starting menu:
IN OUT EXEC
CONF ADJ COM
IN / OUT - selects the input/ output functions.
ADJ - selects functions for the adjustment of the calibrator itself (See adjustment
section). Do not enter in ADJ option before reading the warning in section
4 - Adjustment.

COM - refers to the communication with the computer, described in an appropriate
manual.
EXEC - used to activate an input or output option which has been previously
selected.
CONF –shows the sub-menu:
CF PRG MEM OF
FN BT LCD P DT
CF changes both input and output temperature units from ºC to ºF and vice-
versa. It allows choosing the temperature scale between IPTS-68 and ITS-90. It
follows the encoding scheme described below:
ºC-90 ITS-90 temperature scale in Celsius degrees.
ºF-68 IPTS-68 temperature scale in Fahrenheit degrees.
OF - The calibrator incorporates energy saving resources (battery) through
the automatic power off option (auto-OFF). This option has the following sub-menu:
NO 5MIN
15MIN 30MIN
If NO is selected, the energy saving option is disabled.
If 5, 15 or 30 min is selected, the calibrator will turn off automatically after this
period if the keyboard is not used.

BT shows battery voltage level; if the battery voltage level is low the display
shows LOW BATTERY and you need to recharge it.
Remember that you are only allowed to charge it in safe area.

P - Shows the sub-menu:
UNITIN UNITOUT
P1 P2 PARAM.
P1 and P2 - associates one pressure sensor (C1, C2, C3 or C4) to the
mnemonic P1 or P2. Then, reading of the pressure sensor associated to P1 or P2 is
performed after being enabled through IN or OUT menu.
UNITIN and UNITOUT - contain lists of all pressure engineering units which
can be shown in a measurement by the Calibrator. UNITIN defines the unit of the
pressure value shown in the upper line of the display (pressure chosen through IN
option of main menu) and UNITOUT is related to the pressure value shown in the
presys

Page 19
lower line of the display (chosen in OUT). Note that the units are distributed in
several lines. In order to move the cursor through the units use the keys: , ,
and . After selecting the unit, press ENTER.
The available units are written below between parentheses beside the
corresponding mnemonics presented in the calibrator display:
PSI (psi) ATM (atm) KG (kgf/cm2)
INW (inH2O) MW (mH2O) CMW (cmH2O)
MMW (mmH2O) INH (inHg) CMH (cmHg)
MMH (mmHg) BAR (bar) MBA (mbar)
KPA (kPa) TOR (torr) PA (Pa)
PARAM - configures the calibration parameters of the pressure sensors
provided by the manufacturer.
DT - updates the date and time for the calibrator. Thus, when it performs a
calibration within the communication option, calibration data is recorded together with
their date and time of occurrence.
Whenever the calibrator is turned off, the date and time are not updated any
longer. Thus, if you want them to be recorded with the calibration, you should update
them. Use the vertical arrow keys and to change the value which is blinking and
the horizontal arrow keys and to go to another value. The ENTER key confirms
the last selection
