4 Fluke Corporation ScopeMeter 190 Series II
Bus Health Test Mode (225C and 215C models only)
Bus Health automatically analyzes the electrical signals on the industrial bus system to measure individual parameters and to give waveform
information. Automatically compares the measurement results to preset values and present ‘good,‘weak’ or ’false’ indicator with each parameter.

Meter Mode
190C Series 190 Series II
199C, 196C, 192C, 215C, 225C, 190-204, 190-104
Meter inputs
Via 4 mm banana inputs, fully isolated from
scope inputs and scope ground
Up to four automatic meter measurements
can be made at the same time, using the
oscilloscope input channels
The specifi ed accuracy is valid over the temperature range 18 °C to 28 °C (65 °F to 82 °F).
Add 10 % of specifi ed accuracy for each degree C below 18 °C or above 28 °C.
