WELCOME
This detailed operating manual will help you to become familiar
with the many features of the PC6-IDOS Calibrator. The simple step by step
instructions will quickly guide you through the procedures for using the
calibrator and other items needed for accurately testing and calibrating
numerous types of instruments. Please t
efore you begin to use the PC6-IDOS.
ake time to carefully read
the whole manual b
Two versions of the PC6-IDOS are available:
PC6-IDOS Calibrator:
PC6-IDOS Indicator:
All of the functions shown in this manual apply to this unit. The Calibrator can be supplied with
a PV211 pneumatic test
system for pressures up to 40 bar (600 psi) or PV212 hydraulic test system for pressures up to 700 bar
(10 psi). Refer to the instructions supplied with the applicable pressure system.
This is a simplified version of the Calibrator and does not include the Voltage/Current
input/output.

SAFETY WARNING!
HIGH PRESSURE
RECHARGEABLE Ni-MH BATTERIES
:
Uncontrolled release of high pressure is hazardous to personnel and may cause
damage to equipment. Before connection of any pressure component to the PC6-
IDOS ensure that the component(s) is/are isolated from the pressure supply and any
internal pressure is released slowly.
Rechargeable Ni-MH batteries must be recycled or disposed of properly.
CAUTION: Use charger supplied by GE Sensing only.
May explode if damaged or disposed of in fire. DO NOT short-circuit.

The Pressure Calibrator is a microprocessor controlled, precision instrument powered by an internal 6V
rechargeable battery pack. It is portable and capable of accurate pressure measurement, voltage or current
measurements and sourcing when calibrating transducers, pressure switches, etc. This section describes the equipment
from an external viewpoint, allowing the user to become familiar with the various controls and connections provided.
The PC6-IDOS is housed in a painted metal
The Keypad is a non-tactile membrane keyboard with six buttons. The keyboard layout is shown below.

1.5 Introduction
The PC6-IDOS enables the user to carry out checks on
pressure transducers, transmitters, pressure switches, pressure
gauges and process indicators quickly and accurately. It is
intended for use as a portable, on-site calibrator, used in close
proximity with the equipment under test and without the need to
remove the unit from its parent system. This section describes
the connections to be made when checking switches,
transmitters, etc. It also lists menu options, selection procedures
and purpose of options available.
1.6 Connections
1.6.1 Pressure Input The PC6-IDOS measures pressure
directly
Alternatively, connect the item under test to the PC6-
IDOS with the adaptors and seals provided.
via the 'Quick-Fit' connectors found at the rear of the
case.
1.6.2 EPM (External Pressure Module)
Different pressure ranges can be read by attaching an
External Pressure Module to the 5-way socket (only available
on single range instruments - ).See Fig.2
Warning: The PC6-IDOS must be switched off prior to
connecting or disconnecting the EPM .
1.6.3 Voltage / Current Input / Output Voltage and Current
readings can be taken by connecting the outputs from the item
under test to the 'V' or 'mA' and 'GND' input sockets on the
connection panel using the connection leads provided.
Warning: When measuring voltage or current, make sure
'GND' is connected (where applicable, see fig. 3)

1.6.4 Switch Test Activate ‘Switch’ function in menu 1.
The switching pressure of a pressure switch can now be
monitored by connecting the contacts of the pressure switch
between the INPUT 'GND' and 'SWITCH' sockets on the
connection panel and pressurizing the pressure switch.
1.6.5 RS232
If the RS232 facility is to be used then connections to the 8-
way socket must be made to the specifications given in the
table below. Alternatively an RS232 communication cable
can be purchased from GE suitable for most RS232
applications as shown below.
To RS232 Standard 9-way
socket on PC6- 'D'type female
IDOS connector
Pin 6 and pin 8 should not be used.

1.6.5.1 RS232 Output
Warning:
1.6.6 Battery Charger
CAUTION:
1.6.7 Voltage Output
Connect the PC6-IDOS to a printer or computer using a suitable
cable (not supplied) as detailed above and set the parameters as
detailed in Para. 2.5 & 2.7. The output can now be obtained as
‘single shot' or ‘timed' as follows:
- This output is available in Display mode when
RS232 status is ON & Log status is OFF. The output cycle is
initiated by pressing the key. Pressing the key cancels
the output. Once initiated, the output is repeated at the selected
time interval (see ‘Event' function, page 26 ) until the key is
pressed.
The internal battery pack may be
recharged (when indicated by the battery low message) by
plugging the charger (supplied) into the '9V' socket.
When recharging internal batteries, only the charging
unit supplied with the PC6-IDOS should be used.
A voltage of +10V or +24V may be
sourced from the PC6-IDOS by connecting to the 4 mm sockets.
A typical application for this voltage output would be to power a
pressure transmitter. ( see Fig. 3. page 10 )
To switch on voltage output function:-
a) Press the key twice to activate 'Set' menu.
b) Select 'V-out' and press the key.
c) Select 'ON' and press the key.
1.6.5.2 Single Shot - This output is always available in Display
mode when RS232 status & Log status are OFF. The output is
obtained each time the key is pressed (provided any
previous output is complete).
The PC6-IDOS must be switched off prior to
connecting or disconnecting the RS232 cable.

1.7 Messages & Parameters
The PC6-IDOS registers pressure input at switch on after the initial start-
up message. The pressure reading is displayed on the top line of the
LCD (see Page 3). Pressure values are monitored, alarm values are
compared, alarm warnings and other information messages displayed
until the unit is switched off.
Any read / write errors to memory detected at switch on will be reported
as: Memory Error ‘Error No.’
When switched on, the unit registers the
same state as when last switched off. The display mode (Operating/Set),
units of measurement, function and parameter settings, alarm limits and
RS232 output control, Port (P1 or P2) selection, logged parameters are
all retained at switch off, with the exception of the following conditions:
A battery low state occurring prior to the switch
off. When switched on, the unit registers the latest retained set of
parameters.
Any TARE value set during use is not retained and
therefore should be set, if required, each time the unit is switched on.
Maximum and Minimum values are not
retained. Current values reflect pressure monitored from the start of the
pressure input.
If the unit is switched off during a LEAK test then the
test will be void. When switched on again the unit will start up in LEAK
test mode.
When the key is pressed the 'switch off' message
is displayed for two seconds accompanied by an audible bleep. Normal
operation may be resumed by pressing any key during switch off.
The PC6-IDOS will automatically turn itself of
after a set period (See Page 31 for instructions)
(Bleep rate 4 Hz) ‘OVERLOAD' occurs when
input pressure exceeds overload pressure level.
(Bleep rate 1 Hz). ‘Low Battery' occurs when
internal battery pack drops below 5.5V. Message flashes for 4 seconds,
after a further 30 seconds, low battery detection is re-enabled.
(Bleep rate 1 Hz)
If the receiving device is not ready for input (e.g. device not connected or
handshake LOW), 10 seconds after starting an output cycle (single shot
or timed output) the message 'Printer Busy' is flashed on the display,
together with an audible warning. If the device does not accept input
within the next 5 seconds then the output cycle is cancelled and output is
stopped until the key is pressed again.
(Bleep rate 2 Hz)
Occurs when measured pressure is lower than the user set Low alarm
value or greater than the user set High alarm value and the
message is flashed. Indication ceases when pressure is equal to
either alarm value or between the values.
(Bleep rate 2 Hz)
Occurs in pressure mode. If the key is pressed once (less than 1
second) the pressure value (upper line) is frozen and the lower line is
flashed with the ‘Display Hold’ message at 1 Hz. Normal display update
resumes when any top row key is pressed.

Error Numbers:-
0 8 9- Onboard eeprom; - RTC; - 2nd Onboard eeprom.
Errors with Pressure Modules will be indicated by the message: "No P1
(or P2) Module" preceeded by "PM EEPROM ERROR" at power on.

Occurs in pressure mode with the pressure switch state display being
selected. When the connected pressure switch changes state, the
pressure value (upper line) is frozen and the pressure switch state (lower
line) display is flashed at 1 Hz unless a log file is open. Normal display
update resumes when the key is pressed.
