6 Commissioning, operation GB 6.3 User Interface The Pascal ET or Pascal ET/IS calibrator has a wide display with touch screen through which it is possible to set up the instrument. The following picture is a typical display of the Pascal ET or Pascal ET/IS.
6 Commissioning, operation 6.3.1 Channel configuration The assignment of a function to a software channel is a simple procedure that guides the operator step by step. The channel assignments are very similar, therefore only one assignment will be shown as example. The following procedure shows how to set up the Pascal ET or Pascal ET/IS for temperature measurement through a Pt100 thermo resistance connected to the input pins of the IN A module (using 4 wires measurement).
6 Commissioning, operation Automatically the program shows the following screen and remains in this position till the operator select what type of parameter to associate to Channel 1.
6 Commissioning, operation Once a particular parameter is selected, for example pressing “T” for temperature, the instrument asks for the channel role: GB Figure 13 – Channel role selection NONE REF DUT to use the channel for simple measurement to use the channel as reference in a comparison calibration to use the channel as measurement of a Device Under Test in a comparison calibration Press one of the above button (NONE, REF, DUT) to define the channel role.
6 Commissioning, operation By selecting I/O the instrument requires now to specify whether to measure a signal or to perform a simulation: for example Measure. GB Figure 15 – Measure or Simulation selection At this point the operator needs to select on which physical channel the thermoresistance has to be connected, example IN A.
6 Commissioning, operation Selecting RTD the page for the thermoresistance set up is shown. Fourteen RTD’s types are available, plus one RTD User (with coefficient defined by the user).

6 Commissioning, operation Once RTD USER is selected, it is possible to set the parameter of the RTD used. GB A B C Ro X = = = = = X * 10-3 °C-1 X * 10ˉ7 °C-2 X * 10-12 °C-3 Resistance @ t = 0,01 °C Value Next step is to define the measurement range. The range selection is necessary during the calibration procedure to define the relationship between the REF and DUT channels.
6 Commissioning, operation 6.3.2 Other assignments 6.3.2.1 Pressure measurement The following procedure illustrates the setting of Pascal ET or Pascal ET/IS for pressure measurement.

Pressing REF or DUT the procedure continues as shown below: I/O to assign a particular I/O module to the software channel.
6 Commissioning, operation By selecting I/O the procedure requires to select the type and the range of the sensor to be used. The sensor is identified by the measurement range and the measurement mode (g = gauge pressure or a = absolute pressure). This information is displayed under the writing PE-1 (first external sensor) or PE-2 (second external sensor).
6 Commissioning, operation GB The next screen shows the Span parameter (measuring range). For default the sensor has its maximum range equal to the measuring range (Span). If the Span has to be redefined, or to be reduced, the same can be changed by using a numeric keyboard. The redefinition of the Span is used during a calibration for comparison where a relationship between a REF and a DUT channel has to be done.
6 Commissioning, operation 6.3.2.2 Thermocouple signal measurement The following procedure shows the setup of Pascal ET or Pascal ET/IS for temperature signal measurement, for example, through a thermocouple connected to the input module. The channel for measurement is selected by pressing one of the four large displays, once the menu CHANNEL is selected, press ASSIGN as shown in the below figure.
6 Commissioning, operation Press T for Temperature. The instrument requires the channel role: GB Figure 33 – Channel role selection NONE REF DUT to use the channel for simple measurement to use the channel as reference in a comparison calibration to use the channel as measurement of a Device Under Test in a comparison calibration Press one of the above button (NONE, REF, DUT) to define the channel role.

6 Commissioning, operation Selecting Tc the page for thermocouple set up is shown as follow: GB Figure 38 – Tc type selection Next page helps the operator to select: the engineering unit (°C - °F - K) and the type of reference cold junction (internal or external). Selecting “internal cold junction”, a Pt100 is directly connected to the TC input pins, measures the environmental temperature; whereas by selecting “external cold junction”, the temperature value must be inserted by using the keyboard.
6 Commissioning, operation GB Figure 40 – Tc range selection Now it is possible to finalize the procedure by pressing the YES button or come back to the previous step pressing NO. Figure 41 - Channel setup confirmation Pressing the key YES, the channel is set up with selected parameters and the screen with four channels is displayed again.

Double input will be displayed when the calibrator has a double input configuration and both modules are not assigned yet.
6 Commissioning, operation The next step shows the span parameter (measuring range). In the default settings, the maximum range is equal to the measuring range (span). If the span has to be redefined or reduced, it can be changed by using a numeric keyboard. To access to the keyboard use the arrows displayed on the right side of the screen. Change of the span is used during a calibration for comparison where a relationship between a REF and a DUT channel has to be assigned.
6 Commissioning, operation GB 6.3.2.4 Temperature Simulation The procedure for the temperature simulation assignment is similar to the measurement one as described previously, except for the step “Select measure or simulation” where the operator needs to press SIMULATION instead of MEASURE. In the following step the user needs to select one of the output OUT A or OUT B available. Figure 52 – Generation module selection 6.3.2.

6 Commissioning, operation GB Calculation is possible only when channel 1 is assigned for mV measurement (bridge signal) and channel 2 is assigned for V generation, range 0÷20 V (bridge supply). Moreover channel 1 should not be set in error mode. In this case, below what will be displayed: Figure 60 – Cell Load calculation Pascal ET or Pascal ET/IS allows to manage the sensitivity of the load cell from 0 mV/V up to 9.99999 mV/V.

6 Commissioning, operation GB 6.3.2.9 HART scale adjust ADJ.SCL permits to align the range of PV to the Lower and Upper mA generation values. The Lower value of PV is the value at which the transmitter will generate the 4 mA nominal value, and the Upper value is the value at which the transmitter will generate the 20 mA nominal value. Here is described the “automated” procedure that permits to align in “real-time” these values. The user can also change them manually in the “HART data” page as seen before.
