Warning

To avoid electrical shock or fire:

• Use only the Fluke power supply, Model

BC190 (Battery Charger / Power Adapter).

• Before use check that the selected/indicated

range on the BC190 matches the local line
power voltage and frequency.

• For the BC190/808 universal Battery Charger /

Power Adapter) only use line cords that
comply with the local safety regulations.

Note:

To accomodate connection to various line power
sockets, the BC190/808 universal Battery
Charger / Power Adapter is equipped with a male
plug that must be connected to a line cord
appropriate for local use. Since the adapter is
isolated, the line cord does not need to be
equipped with a terminal for connection to
protective ground. Since line cords with a
protective grounding terminal are more commonly
available you might consider using these anyhow.

Safety Information: Read First

Warning

To avoid electrical shock or fire if a test tool
input is connected to more than 42 V peak (30
Vrms) or on circuits of more than 4800 VA:

• Use only insulated voltage probes, test leads

and adapters supplied with the test tool, or
indicated by Fluke as suitable for the Fluke
19xC – 2x5C ScopeMeter series.

• Before use, inspect voltage probes, test leads

and accessories for mechanical damage and
replace when damaged.

• Remove all probes, test leads and accessories

that are not in use.

• Always connect the battery charger first to the

ac outlet before connecting it to the test tool.

• Do not connect the ground spring (figure 1,

item f) to voltages higher than 42 V peak (30
Vrms) from earth ground.

• Do not apply voltages that differ more than 600

V from earth ground to any input when
measuring in a CAT III environment.
Do not apply voltages that differ more than
1000 V from earth ground to any input when
measuring in a CAT II environment.

• Do not apply voltages that differ more than 600

V from each other to the isolated inputs when
measuring in a CAT III environment.
Do not apply voltages that differ more than
1000 V from each other to the isolated inputs
when measuring in a CAT II environment.

• Do not apply input voltages above the rating of

the instrument. Use caution when using 1:1
test leads because the probe tip voltage will be
directly transmitted to the test tool.

• Do not use exposed metal BNC or banana plug

connectors.

• Do not insert metal objects into connectors.

• Always use the test tool only in the manner

specified.

Voltage ratings that are mentioned in the warnings, are
given as limits for “working voltage”. They represent
V ac rms (50-60 Hz) for ac sinewave applications and as V
dc for dc applications.

Measurement Category III refers to distribution level and
fixed installation circuits inside a building.
Measurement Category II refers to local level, which is
applicable for appliances and portable equipment.

Fluke 19xC-2x5C

Users Manual

The terms ‘Isolated’ or ‘Electrically floating’ are used in this
manual to indicate a measurement in which the test tool
input BNC or banana jack is connected to a voltage
different from earth ground.

The isolated input connectors have no exposed metal and
are fully insulated to protect against electrical shock.

The red and gray BNC jacks, and the red and black
4-mm banana jacks can independently be connected to a
voltage above earth ground for isolated (electrically
floating) measurements and are rated up to 1000 Vrms
CAT II and 600 Vrms CAT III above earth ground.

If Safety Features are Impaired

Use of the test tool in a manner not specified may
impair the protection provided by the equipment.

Before use, inspect the test leads for mechanical damage
and replace damaged test leads!

Whenever it is likely that safety has been impaired, the
test tool must be turned off and disconnected from the line
power. The matter should then be referred to qualified
personnel. Safety is likely to be impaired if, for example,
the test tool fails to perform the intended measurements or
shows visible damage.

Working with Noisy Waveforms

To suppress high frequency noise on waveforms, you can
limit the working bandwidth to 10 kHz or 20 MHz. This
function smoothes the displayed waveform. For the same
reason, it improves triggering on the waveform.

To choose HF reject, do the following:

1

Display the INPUT A key labels.

2

Open the Input A menu.

Using Mathematics Functions A±B, AxB, A vs B

When adding (A+B), subtracting (A-B), or multiplying (A*B)
the input A and input B waveform, the test tool will display
the mathematical result waveform and the input A and
input B waveforms.

A versus B provides a plot with input A on the vertical axis
and input B on the horizontal axis.

The Mathematics functions perform a point-to-point
operation on waveforms A and B.

To use a Mathematics function, do the following:

1

Display the SCOPE key labels.

2

Open the Waveform Options
menu.

20

Using The Scope
Acquiring Waveforms

3

Jump to Waveform: and Select
Mathematics... to open the
Mathematics menu.

4

Select Function: A+B, A-B, AxB or
A vs B.

5

The sensitivity range of the mathematical result is equal to
the sensitivity range of the least sensitive input divided by
the scale factor.

Select a scale factor to fit the
mathematical result waveform onto
the display, and return.

Using Mathematics Function Spectrum (FFT)

The Spectrum function shows the spectral content of the
input A or input B waveform. It performs an FFT to
transform the amplitude waveform from the time domain
into the frequency domain.

To reduce the effect of side-lobes (leakage) it is
recommended to use auto windowing. It will automatically

functions Cursor, Zoom, and Replay. These functions
can be used with one or more of the primary functions
Scope, TrendPlot or Scope Record.

It is possible to combine two or three analysis functions. A
typical application using these functions follows:

• First replay the last screens to find the screen of

special interest.

• Then zoom in on the signal event.

• Finally, make measurements using the cursors.

About this Chapter

This chapter provides an introduction to the trigger
functions of the test tool. Triggering tells the test tool when
to begin displaying the waveform. You can use fully
automatic triggering, take control of one or more main
trigger functions (semi-automatic triggering), or you can
use dedicated trigger functions to capture special
waveforms.

Following are some typical trigger applications:

• Use the Connect-and-View™ function to have full

automatic triggering and instant display of virtually any
waveform.

Chapter 5

Triggering on Waveforms

• If the signal is unstable or has a very low frequency,

you can control the trigger level, slope, and trigger
delay for a better view of the signal. (See next
section.)

• For dedicated applications, use one of the four

manual trigger functions:

• Edge triggering

• External triggering

• Video triggering

• Pulse Width triggering

Using The Bushealth Function

About this Chapter

This chapter provides a step-by-step introduction to the
Bushealth function of the test tool. For extended
information on Fieldbuses and fieldbus measurement
please consult Appendix A of this manual.

Bushealth Function Availability

The Bushealth function is available in the models
Fluke 215C and Fluke 225C.

Introduction

Fieldbuses are bi-directional, digital, serial control
networks used in process control and industrial
automation.

The test tool bushealth function indicates the status of the
following aspects of the OSI model Physical Layer:

• Voltage levels (bias, high level, low level)

• Bit width – baud rate

• Rise and fall time

• Distortion

Moreover the test tool can show the bus signal waveform
in the Eye-pattern mode, see

Figure 46.

65

Fluke 19xC-2x5C

Users Manual

The bushealth measurement is based upon the test tool
Scope mode. The test tool selects settings that are
optimized to the signal characteristics of the selected bus
type. It operates in full automatic (ranging and triggering)
mode.

Test limits are preset, but can be changed, see page

For supported bus types and protocols see Chapter 10,
Specifications, section ‘Fieldbus Measurements’.

Note

You can perform resistance measurements using
the Meter mode to check a suspected cable or
bus termination.

Input Connections and Tested Signals

This section provides a short description of the required
bus connection and the measured signal properties.

See Appendix A for detailed information.

For correct measurements you should calibrate your
probe to match its characteristics to the test tool. A
poorly calibrated probe can introduce measurement
errors. See Chapter 9, section ‘Calibrating the Voltage
Probes’ for calibration instructions.

Data Traffic

In some bus systems (AS-i for instance) the protocol uses
continuous polling of all devices in a fixed time schedule
so that there is continuous data traffic. Other systems
such as RS-232 only carry data when communication is
required. Bushealth requires continuous data traffic to
perform its measurements. In case of very low data
repetition rates, the banner ‘NO DATA’ is displayed. In
systems with low data rates, it is recommended to
increase the data rate by e.g. knob operation. Contact the
system manager for this.
