15. Calculate the LogBook or Daq device voltage/transducer units. Do this using the transducer
specifications and the total gain of the DBK43 module’s channel. Apply the units to your readings.
16. Verify the software settings by using a known load or strain and comparing the value to that
observed in DaqView’s Reading column.
Note: Gain adjustments can be made by activating a shunt-cal resistor that is calculated to be at
maximum load.
To enable shunt-cal resistors:
(a) Select “Shunt Cal” as the Channel Type.
(b) DBK43A users: Set CAL/NORM switch to CAL.
DBK43B users: Place CAL1 and CAL2 “Up.”
(c) DBK43A users: LogView users: set the software CAL/NORM switch, in Hardware
Configuration, to “CAL.”
DBK43B users: : LogView users verify the software switch parameter is set to
1’CAL+2’CAL.
Settings can be verified via shunt-calibration.
After the final offset is made, the gain readings will be incorrect unless the circuit
offset is removed.
