Measurement And Indication Of Input Types - Novus LogBox BLE Instruction Manual

● Internal Diagnostic Sensors:
○ The Internal Diagnostic Sensors inform the voltage of the possible LogBox BLE power supplies;
○ The maximum resolution for the internal diagnostic sensors is 0.01 V;
○ You can configure them to be displayed with 0, 1, or 2 decimal places;
○ The unit of measure for these sensors is Volts and no unit symbol is displayed.
The accuracy of these types of signals is described in the chapter TECHNICAL SPECIFICATIONS. The connection of these signals is described in
chapter INSTALLATION.
An analog/digital (A/D) converter with high resolution and accuracy is used to read the sensors connected to the analog channel inputs. In the
desired scan range, all the analog channels enabled will be read.
Each type of input signal has a valid measuring range (detailed in chapter TECHNICAL SPECIFICATIONS). However, the device typically can
measure signals which slightly exceed the limits of this range. How much it can measure beyond the range depends on the type of input configured
and might vary between different devices.
The following table describes what to expect in the LogBox BLE display according to the signal applied to the input for each configured input type.
