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 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)
