Voltage input adapter cables
A voltage input adapter cable is a resistive voltage divider that allows a voltage input to be recorded. The
USB-5106 supports the following voltage input adapter cables:
 CABLE-ADAP5 measures 0 V to 5 VDC
 CABLE-ADAP10 measures 0 V to 10 VDC
 CABLE-ADAP24 measures 0 V to 24 VDC
Voltage input cables are for use in indoor environments only.
Figure 7 shows a schematic of the voltage input adapter cable. All resistors are 0.1%.

Reading out the logger
To read out data logged by the USB-5106, connect it to the computer with the USB cable and read out it with
USB-5100 Series Data Logger Software.
Refer to the USB-5100 Series Software Help for detailed information about how to read out logged data.
Recording internal logger events
The logger records the following internal events to track logger operation and status. You can plot these events
after reading out the logger and opening the data file.
Internal Event Name Definition
Host Connected The logger is connected to the computer.
Started The Start/Stop button was pressed to begin logging.
Stopped
The logger received a command to stop recording data (from either the USB-5100
Series Data Logger Software or by pushing the Start/Stop button).
Button Up/Button Down The Start/Stop button was pressed for 1 second.
Chan <#> Alarm Tripped An alarm has tripped on the specified channel.
Chan <#> Alarm Cleared
An alarm has cleared on the specified channel. This event also contains the value that
is furthest out of range for the sensor before the alarm cleared.
New Interval The logger has entered or exited burst logging mode.
Safe Shutdown The battery level dropped below 1.85 V; the logger performs a safe shutdown.
