80 Operating Instructions
To view the LVDT calibration screen:
Click the «Setup» button.
Select an LVDT module from the Tree or the Module view.
Click the «calibration» button.
The LVDT setup screen for the selected module appears.
Set excitation
frequency The excitation frequency is used to supply the correct frequency for all of the sensors
connected to an LVDT module. Sensors that require different excitation frequencies
require a separate LVDT module or they will not run at optimum performance. The
desired frequency should be obtained from the sensor manufacturer documentation.
LVDT modules are preset to default values. The excitation frequency must be a value
from 3.0 to 50.0 kHz.
To change excitation frequency:
Click inside the Exc. desired (kHz) text field.
Delete the current excitation frequency.
Enter the desired value.
Click the «OK» button.
A message verifying the action is displayed in the message area.
The Exc. (Vpp) will be updated with the new voltage that is being used in the
module. This value is affected by both the excitation voltage and the excitation
frequency.
Set excitation voltage The excitation voltage is used to supply the correct voltage for all of the sensors
connected to the module. Sensors that require different excitation voltages require a
separate module or else they will not run at their optimum performance. The desired
voltage should be obtained from the manufacturer of the sensor. LVDT modules are
preset to default values. The excitation voltage must be a value from 1.5 to 5.5 V.
To change excitation voltage:
Click inside the Exc. desired (Vpp) text field.
Delete the current excitation voltage.
Enter the desired value.
Click the «OK» button.
A message verifying the action is displayed in the message area.
The Exc. (Vpp) will be updated with the new voltage that is being used in the
module. This value is affected by both the excitation voltage and the excitation
frequency.
