For DBK16, only … Externally apply the shunt resistor and set the voltage to V
D
, as derived above for each
transducer. This is done by adjusting the trimpots labeled GAIN and SCALE for the associated channel.
The GAIN trimpot is used for course adjustment; and the SCALE trimpot for fine-tuning.
For DBK43A only … For each DBK43A to be adjusted, move the physical switch from NORM to CAL.
For DBK43B only … For each DBK43B to be adjusted, move the two physical switches from RUN to
CAL1
and CAL2 respectively.
2. In LogView, open the LogBook Hardware Configuration window and select the DBK43A.

3. Select the DBK43A [or DBK43B] from the LogBook Hardware Configuration window’s hardware
tree.
4. Set the list box to the right to CAL. If the DBK43A [or DBK43B] is not displayed click the + to the
left of the base channel to which it is attached to expand the hardware tree.

5. Repeat this process for each DBK43A [or DBK43B] that is to be adjusted.
6. Click OK to lock in the changes.
7. Open the Analog Input Channel Grid. In the Param1 column (see page 27 for location), select all of
the DBK43A [or DBK43B] channels that are to be adjusted. Select Mode = Shunt from the drop
down list above the grid. Turn off all the channels in the system except for those DBK43A [or
DBK43B] channels that are to be adjusted.
8. Click the Download button to send the current configuration to the LogBook.
