Oscilloscope Output in Bargraph Mode
In Node Signal Level Bargraph mode, the oscilloscope output is operational in the same way as in
Diagnostic mode. In Global Bargraph mode, however, no trigger signal is provided since there
can be no ControlNet node at address 00.
Operation
This section describes how to operate your NetChecker device.
Install the Batteries
Use a screwdriver to remove the two screws from the battery cover on the back of the
NetChecker. Install the two 1.5V AA batteries supplied as indicated in the compartment.
Batteries installed incorrectly may damage the instrument. Use only alkaline batteries for
replacement.
Conserve Battery Power
To conserve battery power when using the NetChecker, set power switch SW1 to the Push ON
position, then press and hold the Push ON button for just the time necessary (a few seconds) to
read the status indicators. If you need your hands free, set SW1 to the ON position (middle) so
that the NetChecker remains powered on. Remember to put SW1 back to the OFF position
when you are done.
Use a Wall Adapter to Power the NetChecker
The NetChecker may also be powered by a wall adapter connected to the External Power
connector on the side of the tool. The adapter should produce a regulated 5V DC @ 0.25A
(5.5 volts max). The internal batteries are disconnected when the adapter’s jack is inserted in the
connector. The NetChecker remains operating as long as power is provided (switches SW1 and
SW2 are not active in the external power mode; however, it is better to leave SW1 in the OFF
position).
ATTENTION: Make sure that your adapter is CE compliant and that the system formed by the
NetChecker plus the adapter is also CE compliant.
