AutoSearch mode saves you time by finding the network
measurements that exceed acceptable limits. It works by
examining all measurements and then pinpointing any
that exceed
or are close to
specified limits. For
each problem measurement NetMeter indicates the
measurement's switch position number in the upper left
corner of the display. Rotate the selector switch to the
indicated setting to view related measurements.
NetMeter requires 2 ‘AA’ Alkaline batteries for viewing
measurements offline. NetMeter must be plugged into a
powered network to get most measurements. NetMeter
will run off DeviceNet network power, even without
batteries installed. Remember to install batteries if you
plan to use the Lock and offline viewing features.
How to Use AutoSearch ...
1. Make sure the Lock switch is in the “Run” position and
turn the selector switch to AutoSearch
2. If you see
- all measurements are within limits.
3. If you see
or
then read the display like this ...
“Switch setting <Setting #>, <MIN> or <MAX> and/or
<P-P> is close to
or Exceeds
the spec limits.”
Then press and repeat the process for the next
bad/marginal value.To get more detail, turn the
selector switch to the indicated position and use the
buttons
to access related measurements.
