Note 1:
These outputs are available when the unit is used in
USB ADC-11
compatibility mode
.
Note 2:
The ground pins are protected by resettable fuses. If you connect one of the
ground pins to a voltage source such as a power pack, and the voltage
source shares a ground connection with the USB cable to the Data Logger,
then a large current will flow into the ground pin. The fuse will detect this
condition and disconnect the pin before damage is caused to the Data
Logger. The fuse will automatically reset itself when the voltage source is
disconnected from the input pin.
Note 3:
NC = not connected
