directly via the connector found underneath the case (i.e. the
connection between the PC6-IDOS and a hand held pressure
test system). Alternatively, connect the item under test to the
PC6-IDOS with the adaptor and seals provided.

1.6.2 EPM (External Pressure Module)

Different pressure ranges can be read by attaching an
External Pressure Module to the 5-way socket.

(See Fig.3 opposite)

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. 3a)

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 8­way 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.

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 'CHARGER' 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 2 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 start­up 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.

1.7.17 RS232 Output Format

1.7.18 Alarm Flags

In voltage / current source mode, if the PC6-IDOS is unable to control the
voltage/current output (e.g. because there is no loop back in the current
mode), the message “Connection Fault” will flash on the lower line
accompanied by a bleep at 1 Hz. The message will continue until the user
presses the or key ( after fault is rectified ) or the user exits
from source mode.

If the 24V output is ON and it is shorted to 0V, the message “*Short
detected*” will be displayed on the lower line accompanied by a bleep at
1 Hz. This message will be cleared after approximately 5 seconds. In this
condition the 24V supply will be switched off for safety.

In Voltage measure mode, if a voltage in excess of 55V is connected to
the PC6-IDOS the message “*OVERSCALE*” will be displayed on the
lower line, until the voltage falls within the input limits.
In Current measure mode, if a current in excess of 55mA enters the mA
terminal, the PC6-IDOS will display “*OVERSCALE*” on the upper line
and the lower line will scroll the message “Check connections: Press
MENU to continue”. Pressing the key will remove the message
provided the current measured is within range. This message may also
appear in the source mode under connection fault conditions. Source
mode will change to measure mode for safety.
If the current overscale message occurs when the PC6-IDOS is in timed
RS232 output mode, the unit will exit from the timed output mode.
If there is an excess voltage at the mA input when the PC6-IDOS is
placed into current measurement mode, the message “Connection Fault”
will be scrolled on the lower line. Once the fault has been rectified, press
the key to return to measuring mode.

The output format is as follows:
LF
Time & date ( 1100) +LF
display top line (16 characters ) + LF
display lower line (16 characters ) + LF
alarm flag (1 character ) + LF

A single character is output to indicate the various

pressure alarm conditions as given below:

* overload pressure level exceeded

(pressure warnings, 1.7.8 & 1.7.12)
> pressure exceeds user set high limit
< pressure below user set low limit
“ ” a space if no alarms apply.
c connection fault
s short detected

23:13:30 08

Note: If two (or more) conditions occur which require a message display, the
highest priority condition in the above list will be displayed. The sequence of
messages given above set the priority except 'Switch Off' which comes last.

If more than one symbol is applicable, they are displayed one after the other.
