Basic Operations
This section covers the most common functions of your
device. Settings for more specialized needs can be found
after this section. Some information found in this section may
be repeated in other sections for ease of section navigation.
Viewing Live Data
The display screen has a number of options for displaying
live data. There are various ways to modify the display screen
functions, brightness, or orientation. Refer to
display setup
The display screen displays live data for all parameters
measured by the device simultaneously. Sensors measure
data 1000 times per second and the LCD display updates
10 times per second. The measured data is displayed in the
units designated by the device (
).
Interacting with the Device
The images to the right show the buttons of the device display.
These images compare the differences between a mass flow
controller, a pressure controller, and a liquid meter.
Below are the default button functions and their locations
on a given device. Pressing a button to highlight a reading
changes what is centered in the display.
•
Highlight pressure:
all devices use
button 1.
•
Highlight volumetric flow:
mass flow
and liquid devices use
button 4
. Pressure
devices do not measure volumetric flow.
•
Highlight mass flow:
mass flow devices use
button 5
.
Pressure and liquid devices do not measure mass flow.
•
Highlight temperature:
mass flow and
liquid devices use
button 2
. Pressure
devices do not measure temperature.
•
Changing the setpoint:
controllers use
button 3
. Meters and gauges do not have a
setpoint function. Refer to
for more
information on changing the setpoint.
•
Taring the device:
meters and gauges use
button 3
(
TARE FLOW
for meters and
TARE PRESS
for gauges). Pressure controllers use
button 2
.
Mass flow controllers and liquid controllers do not
have a tare button on the default display. Refer to
for further information on taring.
•
Enter the menu or move to the next
screen:
all devices use
button 6.
•
Enable/Disable the backlight:
