2.1 Intended use
The Multichannel Calibrator model Pascal ET or Pascal ET IS gauge can be used as a calibration
instrument and also for any application which requires accuracy pressure measurement.
The Multichannel Calibrator model Pascal ET, ET-P, ET/IS, ET-P/IS has been designed and built
solely for the intended use described here, and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
Improper handling or operation of the Multichannel Calibrator model Pascal ET, ET-P, ET/IS, ET-
P/IS outside of its technical specifications requires the instrument to be shut down immediately and
inspected by an authorized WIKA service engineer.
Handle electronic precision measuring instruments with the required care (protect from strong
magnetic fields, static electricity and extreme temperatures, do not insert any objects into the
instrument or its openings). Plugs and sockets must be protected from contamination.
If the Multichannel Calibrator model Pascal ET, ET-P, ET/IS, ET-P/IS are transported from a cold
into a warm environment, the formation of condensation may result in the instrument
malfunctioning. Before putting it back into operation, wait for the instrument temperature and the
room temperature to equalize.
The manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.
2.2 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient!
Improper handling can result in considerable injury and damage to equipment.
■The activities described in these operating instructions may only be carried out by
skilled personnel who have the qualifications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of
country-specific regulations, current standards and directives, are capable of carrying out the work
described and independently recognizing potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

2.3 Additional safety instructions for instruments with ATEX approval
only Pascal ET/IS
WARNING!
Non-observance of these instructions and their contents may result in the loss of
explosion protection.
■Battery operation:
Use only the rechargeable battery which is supplied by WIKA! Only charge the
battery outside of the hazardous area!
■Operation of the serial interface in the hazardous area is prohibited.
Further hazardous area safety instructions!
Observe the operating information and the relevant country-specific regulations
concerning use in hazardous areas (e.g. EN IEC 60079-14).
The Pascal ET/IS intrinsically safe multichannel calibrator has been designed for use
in Ex Hazardous Areas. These are areas where potentially flammable or explosive
vapors may occur. These areas are referred to as hazardous (classified) locations in
the United States, as Hazardous Locations in Canada, as Potentially Explosive
Atmospheres in Europe and as Explosive Gas Atmospheres by most of the rest of
the world. The Pascal ET/IS intrinsically safe multichannel calibrator is designed as
intrinsically safe. This means that connecting the Pascal ET/IS intrinsically safe
multichannel calibrator to equipment that is used within intrinsically safe circuits will
not cause an ignition capable arc as long as the entity parameters are suitably
matched.
Information/Approval for hazardous locations:
WARNING!
■Ex Hazardous Areas
An Ex-hazardous area as used in this manual refers to an area made hazardous
by the potential presence of flammable or explosive vapors. These areas are also
referred to as hazardous locations.
WARNING!
Only gauges powered by batteries are approved for use in hazardous locations.
Use only the rechargeable battery which is supplied by WIKA! Only charge the
battery outside of the hazardous area!

2.4 Special hazards
WARNING!
■When measuring pressure, make sure that the process pressure line is shut off
and depressurized before it is connected to or disconnected from the pressure
module.
■Disconnect test leads before changing to another measurement or generation
function.
■Observe the working conditions in accordance with chapter "3. Specifications".
■Always operate the device within its overload limits.
■To ensure problem-free operation, only operate the Multichannel Calibrator
model Pascal ET, ET-P, ET/IS, ET-P/IS on battery power. Only use the mains
connection for charging the Hand-held pressure calibrators batteries.
■Do not apply a voltage greater than the specified voltage to the instrument.
See chapter "3. Specifications".
■Make sure that the test probes never contact a voltage source while the test
leads are connected to the current terminals.
■Do not use the calibrator if it is damaged. Before using the multichannel
calibrator, check that there are no cracks or missing plastic parts on the case.
Pay particular attention to the insulation of the connectors.
■Select the proper function and correct measuring range for the measurement.
■Inspect the test leads for damaged insulation or exposed metal. Check the
continuity of the test leads. Damaged test leads should be replaced before using
the multichannel calibrator.
■When using test probes keep fingers away from the test probe contacts. Keep
your fingers behind the test probes' finger guards.
■First connect the common lead, and then the live lead. When disconnecting,
remove the live test lead first.
■Do not use the multichannel calibrator if it is not working properly. The
instrument protection might be compromised. If in doubt, have the instrument
checked.
■Do not operate the calibrator in areas with explosive gases, vapours or dust.
■To avoid false readings, which could lead to possible electric shock or personal
injury, charge the rechargeable battery as soon as the battery indicator appears.
■In order to avoid any possible damage to the multichannel calibrator or the test
equipment, use the correct leads, the correct function and the correct range for the
measuring application.

4.1 Description
Pascal ET, ET-P, ET/IS, ET-P/IS are the Professional Advanced Superior Calibrators of latest
generation. User friendly interface by a wide display with an industrial touch screen through which
it is possible to manage the instrument completely.
The operations are simplified thanks to the touch screen: the display changes in a dynamic way
according to the user selections, following test by step the operator during the calibration process,
decreasing the learning time and the human errors.
The touch screen can be operated by nude or gloved hands: dirty parts can be easily removed with
a cloth or a sponge. The touch screen can be locked during the measurement process to avoid
unintentional pressing of keys.
The backlight illumination with LED guarantees a perfect view in case of low environmental
visibility. Five keys are present below the touch screen: turn on/off of the instrument, contrast
settings and backlight.
The electrical part of Pascal ET, ET-P, ET/IS, ET-P/IS consists from two until 4 electrical modules
to be selected between the available ones (2 inputs (IN) –2 outputs (OUT) –one HART module)
for measuring and generating mA, mV, V, Hz, Ohm, Pulse, TC/RTD.

6.1.2.1 Input module for electrical/temperature signals
The input module for electrical/temperature parameters measurement is one of those modules
inserted from the instrument’s front panel; two slides drive the module into its position. It is possible
to have up to two input modules in the same instrument: IN A and IN B. This terminology is used
also by the software to carry out the connection between physical input IN and software channel.
For example: if you connect a thermoresistance Pt100 to module IN A, the temperature measured
by this thermoresistance can be displayed in any of the four available windows. The following
figure shows the pins connection in electrical/temperature IN module.
Figure 1 –Input panel module
6.1.2.2 Output module for electrical/temperature signals
The output module for electrical/temperature parameters generation or simulation is one of those
inserted from the instrument’s front panel; two slides drive the module into its position. It is possible
to have up to two output modules in the same instrument: OUT A and OUT B. This terminology is
used also by the software to carry out the connection between physical output OUT and software
channel. For example: if you connect a signal-receiver to module output OUT A, the current 4…20
mA generated can be displayed in any of the four available windows.
The following figure shows the output module for electrical/temperature parameters.
Figure 2 –Output panel module
The 2 INPUT cards and 2 OUTPUT cards are plug and play modules and can be installed by the
user himself.
