The Fluke 225C and 215C are the instruments of choice for maintenance specialists who deal with industrial buses and networks as well as with general electronics. You can verify the electrical integrity of your bus and network, performing 'physical layer tests' and getting answers quickly and easily.

Based on the 200MHz or 100MHz 190 Series Color Scopemeters, these instruments offer all functions found in the 190C Series, with Bus Health Test capabilities added on top.

Automatic analysis and validation of
 electrical signal parameters

All common bus types are supported and
accessible through a simple menu structure
 

Bus Health Test
Bus Health Test analyses the electrical signals on the industrial bus or network and gives a clear 'Good', 'Weak' or 'Bad' validation mark for each of the relevant parameters, presented next to the actual measurement value. Measured values are compared to standard values based on the selected bus type, or you may set your personal reference values if you need different tolerances.

All Common Bus Types are Supported
The 225C and 215C Scopemeters support not just one or two bus systems but all commonly seen industrial buses. From the lower speed AS-i and CAN to the higher speed Ethernet 100Base-T based systems are covered by a single instrument.

A simple menu structure allows for selecting the main bus type and, where applicable, sub-types listed in a sub-menu for easy selection. Tested parameters and reference values are then set according the selection made.

Large Color Screen
The large color screen of the 225C and 215C shows the individual parameters with validation, the actual measured value, the minimum and maximum values recorded over time, and the reference values used for the validation.

The choice of parameters differs with the bus type and may include bias voltage, signal high-and low-levels, rise-and fall times, in-band and out-of-band noise levels, jitter, pulse width, baud rate, and more. The activity indicators tell you the data flow is ongoing and they stop flashing the moment communications come to a halt.

Making Test Connections
The large screen also gives wiring information for each of the supported bus types giving the user guidance in making the test connections. A set of break-out adapters is included with the 225C and 215C to give access to each of the wires and pins of the commonly used connection systems M12, DB-9 and RJ-45.

On Screen Help
On screen 'help' information includes visual guidance on making the test connections. The independently isolated input channels of the 225C support truly differential measurements on bus systems.
