4.5.2.1 Displaying multiple process parameters
The procedure for displaying a single process parameter in
a text screen may be repeated to simultaneously display
multiple process parameters. To do so, proceed as follows:
1. Display the first process parameter in a text screen, as
described in the previous section.
2. Repeat Step 1 for any desired additional process
parameters, by double clicking on them in the PanaView
network tree. PanaView automatically tiles the multiple
text screens in the right pane of the Text Display window,
as shown in Figure 21 below.

3. As in any standard Windows® application, the multiple
text screens may be resized by dragging their borders.
Also, the individual panes within a parameter’s text
screen may be resized by dragging the borders within
that text screen.
4. To close an open text screen, right click anywhere within
that screen, except in the title bar or the error section,
and click on the [Remove] option that pops up in the
context menu.
Note: After resizing or removing any of the multiple text
screens, the default tiled layout may be restored by opening
the Window menu (see the PanaView User’s Manual) and
clicking on the Tile Output Displays option.
4.5.2.2 Displaying multiple text windows
The procedures for displaying one or more process
parameters in a single Text Display window may be
repeated to open multiple Text Display windows. To do so,
proceed as follows:
1. To open another
Text Display window and display the
desired process parameter(s) in the new window, repeat
the steps in “Programming the PanaView Display” on
page 40.
2. Arrange the multiple Text Display windows as desired
via the Window menu (see the PanaView Manual ).
4.5.3 Pausing measurements
On occasion, you may wish to stop taking measurements.
With PanaView , you can direct the PanaFlow Z1G/Z2G
Process Gas Flowmeter to pause measurements without
disconnecting the power from the meter. Proceed as follows:
1. From the meter tree in the
New Meter Browser , click on
the PanaFlow Z1G/Z2G Process Gas Flowmeter entry.
2. Expand the Edit Functions option, and double-click on
the Pause Measurement entry to open a window similar
to Figure 22 below.

3. To pause the active measurements, double-click on the
Stop Measurement option. The window closes and the
PanaFlow Z1G/Z2G Process Gas Flowmeter stops taking
measurements.
4. To restart the measurements, double-click on the Pause
Measurement entry, and then on the Measure Flow
option. The PanaFlow Z1G/Z2G Process Gas Flowmeter
resumes flow measurement.
4.6 PT sensor drift and recalibration
The PT sensor is an optional accessory, that comes with
select models of Z1G/Z2G. The sensor is specified to have a
maximum drift of 0.1% of full scale (FS) output per year.
Although, the output drift of this sensor reduces over time,
as the innate stresses in the materials relax and stop
shifting around, we recommend removing the sensor for
recalibration every 5 years. However, user may decide
on the recalibration frequency based on the application
process needs, to have it calibrated earlier than the
recommended period.
When the sensor is removed for calibration, either install
the spare sensor or an approved Ex d plug to close the
sensor mounting slot. Follow all the safety precautions and
recommendations while removing and installing the sensor.
Send the sensor to the Customer Support Center addresses
mentioned on the rear cover of this manual. We will return
the calibrated sensor to the specified address, along with
the calibration certificate
