Calibration Parameters Tab selected
Note: The Calibration Parameters tab has more columns than can be display at once. For this reason, two
images are provided (scroll bar to the left and scroll bar to the right).
WBK16 Sensor Configuration Window
Calibrate? Choosing “yes” will enable the selected channel to be calibrated with the “calibrate enabled
channels” option. Selecting “no” will disable the channel from being calibrated. All other
columns for that channel will be disabled if “no” is selected. The channel can still be turned
on in WaveView.
Sensor Type Choose the sensor type from strain gage, load cell, or transducer.
Bridge Type Choose the bridge type from full-bridge, half-bridge, or quarter-bridge. This option is only
available for a strain gage sensor in the calibration program. The bridge type for any
sensor can be changed from the WBK16 Sensor Configuration window.
Calibration Method Choose the calibration method from Name Plate, Shunt (Ra), Shunt (Rb), Shunt (Rc), 2-
Point Manual, or 2-Point Automatic. Calibration methods are explained later in the manual.
Calibration Date This column displays the time and date that the channel was calibrated. If the channel has
not been calibrated, “Not Calibrated” appears in the box.
Units To change the units: highlight the desired box, type-in the new parameters, and then press
on the keyboard or select another box with the mouse. Up to 5 characters can be
entered into this column. To fill the entire column with the value of channel one, make sure
“yes” is selected in the “Calibrate” column. Then click on the column label with the mouse.
A message box will appear. Click on “yes”. All channels with the “calibrate” function
enabled will be filled. Changing the units here will also change the units column in the
WaveView Configuration main window.
Label Identifies the channels.
Sensor Label A serial number or other identifying label for the sensor can be entered here. Up to 39
characters may be entered and 16 will be displayed. The fill option is available for this
column (see Units).
Calibration Parameters Section of Window, Two Views
Exc. Volts This column is used to change the excitation voltage. Choose between 10.0, 5.0, 2.0, 1.0, .5,
and off. Changing the excitation voltage on any channel between one and four will change
the value on all four lower channels. Likewise, changing the excitation voltage on any
channel five through eight will change the value on all four upper channels. Changing the
Excitation Voltage here will also change the Source Level column in the WaveView
Configuration main window.
Gage Factor This column is used for calibrating strain gages using the Name Plate calibration method. To
change this value, select the box and enter a number greater than 0 and less than 1000.
The fill option is available for this column (see Units).
