CALIBRATION TYPE
Menu Item
This chooses the type of calibration technique to be used. There are three meth-
ods that can be used to calibrate the transducer to the Input Channel. Each has
advantages and disadvantages as described in the table below.

It is important to know your application in order to select the appropriate cali-
bration type. mV/V ("millivolt-per-volt") Calibration is recommended for most
applications because it doesn't require known loads and it allows easy swapping
of transducers equipped with Signature Calibration. When the best possible
accuracy is required, Known-Load Calibration is recommended.
