CALIBRATION
QStar UFM provides a calibrating function that can be
used to calibrate the flow. It may also be used to calibrate
the analog outputs and temperature sensors.
To access the “Calibration” menu:
In the primary measuring window “Flow 1”:
Select
“SETUP” -> “CMPL SETUP” -> Navigate to “Calibration
Setup” in the main menu”.
CALIBRATING FLOW
Select “Flow” from the calibration menu”.
Enter an offset percentage that is relative to calibration
reference.
i
To calibrate QStar UFM, we recommend you
take measurements at different flow velocities
then calculate the mean value of the results. GPI
calculates the mean value based on five differ
-
ent flow velocities. The flow offset is retained in
device memory until it is overwritten with a new
value word.

SYSTEM SETTINGS
To access the “System settings” menu:
In the primary measuring window “Flow 1”
:
Select
“SETUP” -> “CMPL SETUP” -> Navigate to “System
Setup” in the main menu
Editing the Time and Date
To access the “Time and date” menu:
In the primary measuring window “Flow 1”:
Select
“SETUP” -> “CMPL SETUP”. In the main menu, select
“System Setup “ -> “Time and date
Enter the time with the format hh(hour):mm(minutes):ss
(seconds). Enter the date with the format: mm(month).
dd(day).yy(year).
Modifying the Display Backlight
To access the “Backlight” menu:
In the primary measuring window “Flow 1”:
Select
“SETUP” -> “CMPL SETUP” — In the main menu, select
“System Setup” -> “Backlight”
Adjust the display brightness by setting value (0% = no
backlight, 100% maximum brightness).
