TCS – Temperature Compensator Setup
As earlier mentioned, the 4300C needs to reference a temperature coefficient and a temperature
reference to calculate the compensated value. Stored in the instrument’s memory are six configurations
that can be selected. The table below illustrates the values associated to each of the configurations.
The following procedure illustrates how to select one of these configurations and how to setup a
customized configuration. This procedure does not need to be repeated every time the TCM mode is
selected. The configuration that is selected or the custom values inputted will be set as default.
Press “ F
