Quick Start
The most important steps to a successful measurement
Switch the electronics unit on, and
start QSoft 401. Wait a few
seconds for the program to establish
connection to the instrument. When
“Tact” shows a value on the information
bar below the main screen, the connection
is established.
Click on the temperature info bar
to access the Temperature
Control settings window.
(Optional) To display the
temperature stabilization before
starting the measurement, the
“Preacquisition form” could be opened.
Connect tubing and pump to the
flow module.
►Before inserting a sensor, make sure
that the o-ring is lying flat in its bed.
►Insert the sensor crystal with the
backside electrode positioned as the
symbol indicates; close the flow module
(finger tight) and place on chamber
platform.
►For liquid measurements, fill the system
with the start solution/ buffer and make
sure no air is introduced.

In the main menu, go to “Acquisition” and then “Setup Measurement” and
pick the overtones to be measured, by ticking the boxes.
►For standard measurements, make sure “Automatically optimize all resonances” is
checked.
►Start searching for the resonances by clicking “Find all”. Dvalues in water should be
within 20% from the typical values listed above. A larger deviation from these values
indicates:
- The sensor may be incorrectly
mounted in the flow module –
check carefully that it is lined up
and lies flat. A good sensor
should show clean peaks as the
one to the right:
- The sensor might be damaged
– try a different sensor.
- There is a trapped air bubble
over the sensor surface
Start measuring by clicking
”Start Measurement”
under “Acquisition” in the main
menu.
