3.1
Connection by USB
USB connector is used for communication with ADT42-PC program which is used for device
configuration and measurement data acquisition. After connecting to PC and starting ADT42-PC
program there should appear information about connection with ADT42. Installation of USB port
drivers isn’t required.
CAUTION
1)
USB connection should be established always before turning on of driver power
supply.
2)
Connection through USB is susceptible to interferences in supply network and to
electromagnetic interferences, which occurs in industry conditions. While occurring
problems with communication the module with ADT42-PC program, you should use
additional protection elements like:
Power line filter before feeder, which supplies the module,
Good quality USB cable with length < 1,5 m, equipped with ferrite beads,
Opt insulated USB HUBs on PC side.
In some conditions can occur, that communication won’t be possible or measurement data
acquisition won’t be correct.
3.2
Configuration of strain gauge inputs and measurements
After activation of ADT42-PC application you should open Settings
tab, and then to Sensor
inputs
tab.
1)
It allows to define number of active inputs. For
example at operations with two force sensors you
should choose 1 + 2. Values from selected channel are
available as independent measurements and as their
aggregate. Results are presented in „Measurements”
tab.
2)
Filtration options allows to decrease or to eliminate
fluctuations to achieve the highest measurement
stability.
3)
Parameter settings of force sensors:
bridge constant
[mV/V]
and
bridge range [N].
It allows also zeroing of
selected channel.
4)
It cause zeroing of total measured value. It is
equivalent with giving signal on IN1(TARA) input.
5)
