Getting Started Introduction This Getting Started manual provides basic information on the Fluke 434 and 435 Three Phase Power Quality Analyzers. Fluke 435 has additional features such as Mains Signaling, Logging, 0.1 % voltage input accuracy acc. to IEC61000-4-30 2003 Class A, extra memory to store Logging data, Power Log software, flexible current clamps, and a heavy duty trolley style case. For complete operating instructions, refer to the Users Manual on the accompanying CD-ROM.
Fluke 434/435 Getting Started A Caution identifies conditions and actions that may damage the Analyzer. Warning To avoid electrical shock or fire: • • • • • • • • Review the entire manual before use of the Analyzer and its accessories. Avoid working alone. Do not operate the Analyzer around explosive gas or vapor. Use only insulated current probes, test leads and adapters as supplied with the Analyzer, or indicated as suitable for the Fluke 434/435 Analyzer.
Getting Started If Safety Features are Impaired Max. Voltage at Current BNC Inputs (See marking): Input A (L1), B (L2), C (L3), N to GND:.......... 42 V peak Voltage ratings are given as “working voltage”. They should be read as V ac rms (50-60 Hz) for AC sine wave applications and as V dc for DC applications. Measurement Category IV refers to the overhead or underground utility service of an installation. Cat III refers to distribution level and fixed installation circuits inside a building.

Getting Started Tilt Stand Tilt Stand The Analyzer has a tilt stand that allows viewing the screen at an angle when placed on a flat surface. With the tilt stand folded out, the optical port at the right side of the Analyzer can be accessed. Auxiliary Functions Hang Strap Power On/Off: A hang strap is supplied with the Analyzer. The figure below shows how to attach the strap correctly to the Analyzer.
Fluke 434/435 Getting Started Brightness: Press to dim or brighten the backlight. Dimmed brightness saves battery power. For extra brightness keep pressed for 5 seconds. Use the up/down arrow keys to highlight ‘Date’. The current date shown. ENTER Contrast adjustment of the display is explained in the next section as a part of ‘Menu Navigation’. Press to access the DATE ADJUST submenu. Highlight ‘Day’. Adjust the Date.
Getting Started Input Connections Input Connections The Analyzer has 4 BNC-inputs for current clamps and 5 banana-inputs for voltages. Self-adhesive decals are supplied corresponding to wiring color codes used in the USA, Canada, Continental Europe, the UK, and China. Stick the decals that fit to your local wiring codes around the current and voltage inputs. De-energize power systems before making connections whenever possible.
Fluke 434/435 Getting Started Measuring Modes, a Quick Overview This section gives an overview of all measuring modes. The Analyzer’s screen information and use of function keys is explained in more detail in the next two chapters. SCOPE SCOPE MODE. The following features are available: Measuring Mode Scope Waveform Scope Phasor MENU Screen Type Waveform Vector Diagram Cursor/Zoom Yes / Yes No / No MEASUREMENTS MENU. Measuring Functions accessible via the MENU key.

F5 Screen Type Bar Graphs Events Table Trend Bar Graphs 10 Representation of Measuring Results Via start menu: overview of key Power Quality metries. Detailed information available under function keys F1 (V rms), F2 (Harmonics), F3 (Flicker), F4 (Dips, Interruptions, Rapid Voltage Changes, Swells), and F5 (Unbalance, Frequency, Mains Signaling).
Getting Started Screen Symbols Screen Symbols Symbols may appear in the upper and the lower screen areas to show the state of Analyzer and measurements. Status Indicators in the upper screen area: Time that a measurement has been going on. Format: hours, minutes, seconds. When waiting for a timed start, time counts down with prefix -. Horizontal ZOOM on. Measurement may be unstable. E.g. for frequency readout during absence of voltage at reference phase A (L1).
Fluke 434/435 Getting Started Screen information: Screens and Function Keys The Analyzer has five different screen types to show measuring results. Each screen type is arranged to present data in the clearest way. Phases are indicated with individual colors. Selections are done with arrow and function keys: an active selection is highlighted by a black background. Each screen and its features are explained below. Read this carefully to get acquainted with all functions of your Analyzer.
Getting Started Screens and Function Keys Function keys: TREND screen. 1 2 The Trend screen shows the changes over time of measuring values on one row of the Meter screen. An example is the VOLTS/AMPS/HERTZ TREND. Time is displayed horizontally. The display is built up from the right side of the screen. To allow continuous recording of data, the time axis is compressed when necessary. Screen information: c Present values of the trend graphs on the right side of the screen.
Fluke 434/435 Getting Started WAVEFORM screen An example is the Scope Waveform screen. Voltage and current waveforms are displayed similar to an oscilloscope. Function keys: F1 Selection of waveform set to be displayed: V displays all voltages, A displays all currents. A (L1), B (L2), C (L3), N (neutral) gives simultaneous display of voltage and current of the selected phase. F2 Switches to submenu for CURSOR and ZOOM operation. F3 Switches to the Scope Phasor screen. For description see below.
Getting Started Screens and Function Keys PHASOR screen. Function keys: Shows phase relation between voltages and currents in a vector diagram. An example is the Scope Phasor screen: F1 Selection of data set to be displayed. F3 Return to Scope Waveform screen. F5 Switches between HOLD and RUN. 1 2 3 BAR GRAPH screen. An example is the bar graph screen for Power Quality Monitoring. This screen gives a quick indication if important Power Quality parameters meet requirements.
Fluke 434/435 Getting Started You can use a pre-defined set of limits or define your own. An example of a pre-defined set of limits is that according to the EN50160 standard. Power Quality Monitoring is accessible via the MONITOR key and a menu for immediate or timed start. Measuring values of the bar graph under the cursor are displayed in the header of the screen. c Extreme values of the bar graph under the cursor. Use the left and right arrow key to move the cursor to another bar graph.
Getting Started Setting up the Analyzer Setting up the Analyzer Use the arrow keys to select and adjust the selected item. SETUP F5 Press F5 to confirm the selection and to return to the SETUP menu. Note: Limits gives access to submenus to recall, customize, and save 6 sets of Power Quality criteria. For detailed information refer to Chapter 18 in the Users Manual on the accompanying CD-ROM. The SETUP key gives access to a menu to configure the Analyzer for your measurements.
