5.2 INSTRUMENT OPERATION
This section describes how the instrument processes input data and activates outputs.
The diagram below shows the sequence of processing.
5.2.1 INPUT PROCESSING
The electrical input is read in and converted to a digital value, corrections are made
for offset and drift. Readings are made ten times a second.
5.2.2 SIGNAL CONDITIONING
This process depends largely upon the menu programming. If the input is a
temperature sensor, the temperature characteristic is linearised here. If the input is a
voltage or current, the conditioning will be Linear, Square root, Power Law or User
defined, as programmed in the Inputs menu.
5.2.3 FILTERING
The programmable filter reduces noise from the conditioned input.
