INPUT SIGNALS READING

LogBox BLE allows users to choose, along with channels to be registered and sensor types, some configurations that provides flexibility to various
applications, allowing users to consider the energy resources (battery life) and data storage (length of log memory). Thus, it is possible to configure
the device with the following parameters:
● Log Interval: Frequency, in seconds, with which an acquisition must be made and logged in the memory. Low frequency increases battery
consumption and fills memory faster.
○ Minimum Interval:
■ 1 second (If no channel is configured to operate on average);
■ 10 seconds (If a channel is configured to operate on average).
○ Maximum Interval: 24 hours.
● Display Update Interval: Frequency, in seconds, with which an acquisition must be made and updated on the display. It allows you to save
memory by configuring it to a larger range of logs with a faster Display update rate. Low interval increases battery consumption. This range can
be disabled by configuring it to '0'. Thus, the display update will take place in the log interval.
○ Minimum Interval: 1 second;
○ Maximum Interval: 1 hour.
When configuring a display update interval, it should be less than the log interval. Otherwise, it will be ignored, and the display will be updated in
the Log Interval.
The display update interval only updates analog channels that are not configured to operate on average. Thus, the digital channel that is configured
to operate in pulse counting mode and the analog channels that are configured to operate on average will only have their information updated at
each log interval.
If the digital channel is operating in the "Event Log" mode, it updates its respective information on the display to each event.

ANALOG INPUTS

LogBox BLE has three channels for reading analog signals. The types of signals and sensors accepted are:
● Temperature Sensors:
○ Thermoresistance Pt100;
○ Thermocouples J, K, T, N, E, R, S and B;
○ Internal Temperature Sensor.
● Linear Sensors:
○ 0 to 50 mV;
○ 0 to 5 V;
○ 0 to 10 V;
○ 0 to 20 mA;
○ 4 to 20 mA.
● Internal Diagnostic Sensors:
○ Battery Voltage;
○ External Power Supply Voltage.
Each of these types of sensors has specific operation configurations and characteristics. Below are described these configurations and
characteristics:
● Temperature Sensors:
○ Temperature Sensors inform the measured sensor temperature within the possible measuring range of each sensor.
○ The maximum resolution for the Temperature Sensors is 0.1 °C;
○ You can configure them to be displayed with one or no decimal places;
○ You can configure them to be displayed in units of measure °C or °F.
● Linear Sensors:
○ The Linear Sensors inform some magnitude, in the range required by the user (User Range), as configured in the "Lower Limit", "Upper
Limit", and "Number of Decimal Places" parameters.
■ Number of Decimal Places: you can choose to use 0, 1, or 2 decimal places;
■ Lower Limit: Value configured by the user to represent the minimum value of the chosen sensor;
● Minimum -19999 to 0 decimal places;
● Minimum -1999.9 to 1 decimal place;
● Minimum -199.99 to 2 decimal places.
■ Upper Limit: Value configured by the user to represent the maximum value of the chosen sensor;
● Maximum 19999 to 0 decimal places;
● Maximum 1999.9 to 1 decimal place;
● Maximum 199.99 to 2 decimal places.
○ You can configure them to be displayed in units of measurement °C, °F or customized (8 characters - will not show on the display);
○ The maximum resolution for Linear Sensors is a ratio between the User Range and the maximum resolution of the chosen sensor.
