5.4.2
Configuring the inputs
The home page shows six panels and four buttons. If the unit is unconfigured, all six
panels will display 0.0000. Additional panels can be displayed by scrolling left or right.
1
Tap once on a panel. The Channel Display Configuration
page is displayed (see
).
2
Choose a sensor input from the drop-down menu in the
Devices
field.
The sensor names are initially of the form
BoardBN.DTSN
.
Where:
Board
=
MB
for Mother Board or
DB
for Daughter Board.
BN
= Board Number.
DN
= Device Number.
DT
=
T
for Temperature sensor,
H
for Heater,
L
for Level Meter, or
G
for Gas-flow
Controller.
SN
= Signal Number.
3
Tap
Signals
and select
Temperature
.
4
Tap
Assign
to save the changes and to return to the Home page.
5
If required, configure the other panels on the Home page in a similar fashion.
5.4.2.1
Configuring the sensor details
1
Tap a configured panel on the Home page. The Sensor Details page is displayed.
2
Tap the
Sensor Type
field and select a sensor type from the drop-down menu.
3
Tap the
Calibration
field and select a calibration file from the drop-down menu. If
you select the Generic calibration file, you can adjust the calibration to suit a
particular sensor (see
4
Tap the
Excitation
field and select an excitation mode from the drop-down menu.
5
Tap the
Excitation Magnitude
field and enter an excitation value:
current in
μ
A for Diode or PTC sensors
voltage in mV for NTC sensors.
6
If required, tap the field containing the name of the sensor and enter a new name.
(e.g. Change
DB3.T1
to
Zone 1 Temperature
.).
7
Tap
Home
. The Home page is displayed. If the sensor has been configured
correctly, the selected panel will display a sensor reading.
5.4.2.2
Using a generic calibration-file
Overview of using a generic calibration file
Some generic calibration-files are supplied for common sensors having reasonably
predictable forms of resistance as a function of temperature, for example sensors that
conform to an ITS-90 standard. However the response of an individual sensor may
deviate slightly from the standard curve.
