Warning

To avoid electrical shock or fire:

• Use only the Fluke power supply, Model

BC190 (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 Power Adapter

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

Note:

To accommodate connection to various line power sockets, the BC190/808 universal 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.

Warning

To avoid electrical shock or fire if a product input is connected to more than 42 V peak (30 Vrms) or 60 V dc:

• Use only insulated voltage probes, test leads

and adapters supplied with the product, or indicated by Fluke as suitable for the Fluke 190 Series II 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 power adapter first to the

ac outlet before connecting it to the product.

• Do not touch voltages >30 V ac rms, 42 V ac

peak, or 60 V dc.

• Do not connect the ground spring (figure 1,

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

• Do not apply more than the rated voltage,

between the terminals or between each terminal and earth ground.

Users Manual

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 IV refers to the overhead or underground utility service of an installation. 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.

The terms ‘Isolated’ or ‘Electrically floating’ are used in this manual to indicate a measurement in which the product input BNC 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.

Fluke 190-062, 190-102, 190-104, 190-202, 190-204: The BNC jacks can independently be connected to a voltage above earth ground for isolated (electrically floating) measurements and are rated up to 1000 Vrms CAT III and 600 Vrms CAT IV above earth ground.

Fluke 190-502: The BNC 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 product in a manner not specified may impair the protection provided by the equipment.

Do not use test leads if they are damaged. Examine the test leads for damaged insulation, exposed metal, or if the wear indicator shows.

Whenever it is likely that safety has been impaired, the product must be turned off and disconnected from the line power. The matter should then be referred to qualified personnel.

Smart average

In the normal average mode occasional deviations in a waveform just distort the averaged wave shape, and do not show up on screen clearly. When a signal really changes, for instance when you probe around, it takes quite some time before the new wave shape is stable. With smart averaging you can quickly probe around, and incidental waveform changes like a line flyback in video show up on screen instantly.

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 4

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 three

• Edge triggering

• Video triggering

• Pulse Width triggering

Tips Using the Independently Floating Isolated Inputs

Using the Independently Floating Isolated Inputs

You can use the independently floating isolated inputs to measure signals that are independently floating from each other.

Independently floating isolated inputs offer additional safety and measurement capabilities compared to inputs with common references or grounds.

Measuring Using Independently Floating Isolated Inputs

The test tool has independently floating isolated inputs. Each input section (A, B, C, D – A, B, METER INPUT) has its own signal input and its own reference input. The reference input of each input section is electrically isolated from the reference inputs of the other input sections. The isolated input architecture makes the test tool about as versatile as having four independent instruments. The advantages of having independently floating isolated inputs are:

• It allows simultaneous measurement of independently

floating signals.

Figure 39. Electronic Connections for Measurements

Using Hook Clips and Alligator Clip Grounding

Warning

To avoid electrical shock, re-apply the insulation sleeve (Fig. 1 item e)) over the probe tip when the hook clip is not used. This also avoids the risk of accidently interconnecting the reference contact of multiple probes when groundleads are connected.

Find Quality Products Online at: sales@GlobalTestSupply.com

www.GlobalTestSupply.com

Fluke 190 Series II

Users Manual

• Additional safety. Since the commons are not directly

connected, the chance of causing short circuit when measuring multiple signals is greatly reduced.

• Additional safety. When measuring in systems with

multiple grounds, the ground currents induced are kept to a minimum.

Because the references are not connected together inside the test tool, each reference of the used inputs must be connected to a reference voltage.

Independently floating isolated inputs are still coupled by parasitic capacitance. This can occur between the input references and the environment, and between the input references mutually (see Figure 40). For this reason, you should connect the references to a system ground or another stable voltage. If the reference of an input is connected to a high speed and / or high voltage signal, you should be aware of parasitic capacitance. (See Figure 40 , Figure 42, Figure 43 and Figure 44.)

Note

The input channels are electrically isolated from the USB port and from the power adapter input.

Figure 40. Parasitic capacitance between probes,

instrument and environment

Warning

To avoid electrical shock, always use the insulation sleeve (Fig. 1 item e)) or the probe tip when using the probe reference (ground) lead. The voltage applied to the reference lead is also present on the ground ring near the probe tip, see Figure 41.
