INPUT SIGNALS READING
LogBox Wi-Fi
allows users to choose, in addition to the channels to be registered and sensor types, some configurations that provides flexibility to
several applications, offering the possibility of weighing 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 Range:
Shows frequency, in seconds, with which an acquisition must be made and logged in the memory. A low periodicity will increase
battery consumption and fill up the memory faster.
○
Minimum Range:
■
1 second (if no channel is configured to operate on average)
■
10 seconds (if a channel is configured to operate on average)
○
Maximum Range:
18 hours.
●
Display Update Range:
Shows 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 without damaging the Display update rate. Low frequency increases battery
consumption. This range can be disabled if set to ‘0’. Thus, the display update will take place in the log range.
○
Minimum Range:
1 second
○
Maximum Range:
1 hour
When configuring a Display Update Range, it should be less than the Log Range. Otherwise, it will be ignored, and the display will be updated at
the same Log Range.
The Display Update Range only updates Analog Channels that are not configured to operate on average. Thus, the Digital Channel that is
configured to operate in counting mode and the Analog Channels that are configured to operate on average will only have their information updated
at each log range.
If the digital channel is operating in the "Event Log" mode, each event will update its respective information on the display.

ANALOG INPUTS
LogBox Wi-Fi
has three channels for reading analog signals. The types of signals and sensors accepted by them 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 type has specific operation configurations and characteristics. Its configurations and characteristics are described below:
●
Temperature Sensors:
○
Inform the measured 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:
○
Inform you of some magnitude in the range required by the user (defined in the parameter "User Range"), as configured in the "Lower
Limit", "Upper Limit", and "Number of Decimal Places" parameters.
■
Number of Decimal Places:
Allows you to choose to use 0, 1, or 2 decimal places.
■
Lower Limit:
Corresponds to the value configured 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:
Corresponds to the value configured 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
