Fluke 805 Vibration Meter Instruction Manual

Introduction

The Fluke 805 Vibration Meter is a precision instrument designed to simplify vibration screening and provide reliable measurements for critical maintenance decisions. Unlike a simple vibration pen, this meter offers comprehensive data to assess machine health.

Key capabilities include overall vibration measurement (10 Hz to 1,000 Hz) for acceleration, velocity, and displacement, as well as Crest Factor+ for reliable bearing assessment (4,000 Hz to 20,000 Hz). It features a colored lighting system for pressure indication, an infrared temperature sensor, on-board memory for up to 3500 measurements, audio output for bearing tones, and external accelerometer support for hard-to-reach areas.

Setup

Battery Installation

The Fluke 805 Vibration Meter operates on two AA lithium iron disulfide batteries, which are included with the device. To install or replace batteries:

1. Locate the battery compartment cover on the back of the device.
2. Open the cover and insert two AA batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

A full set of batteries provides approximately 250 measurements.

Initial Power On

Press the power button (labeled with a circle and vertical line) to turn on the device. The high-resolution screen will illuminate, displaying the main measurement interface.

Operating the Fluke 805 Vibration Meter

Taking Measurements

The Fluke 805 simplifies vibration analysis with its intuitive operation. Follow these steps to take a measurement:

1. Ensure the device is powered on.
2. Select the desired measurement mode (e.g., Overall Vibration, CF+) using the navigation buttons.
3. Place the sensor tip firmly against the equipment surface at the desired measurement point.
4. Press the MEASURE button. The colored lighting system (green for sufficient pressure, red for insufficient pressure) will guide you to apply the correct contact force.
5. Hold steady until the measurement is complete and the results are displayed on the screen.

The meter provides overall vibration measurements (10 Hz to 1,000 Hz) in acceleration, velocity, and displacement units. For bearing assessment, the Crest Factor+ function measures between 4,000 Hz and 20,000 Hz.

Interpreting Results

The Fluke 805 provides a four-level severity scale to indicate the condition of overall vibration and bearing health. This allows for quick assessment of equipment status (e.g., Good, Needs Attention).

The integrated infrared temperature sensor also provides temperature readings, enhancing diagnostic capabilities.

Data Management

The device has on-board memory capable of holding up to 3500 measurements. Data can be exported via USB for further analysis and trending in Microsoft Excel using built-in templates.

For hard-to-reach locations, an external accelerometer can be connected. The built-in flashlight assists in viewing measurement locations in dark environments.

Maintenance

Cleaning and Storage

To ensure the longevity and accuracy of your Fluke 805 Vibration Meter, follow these maintenance guidelines:

• Wipe the device with a damp cloth and mild detergent. Do not use abrasive cleaners or solvents.
• Ensure the sensor tip is clean and free of debris before and after each use.
• Store the meter in a dry, cool environment, away from direct sunlight and extreme temperatures.

Battery Replacement

When the battery indicator shows low power, replace both AA batteries promptly to maintain optimal performance. Refer to the "Battery Installation" section under Setup for detailed instructions.

Troubleshooting

If you encounter issues with your Fluke 805 Vibration Meter, consider the following common troubleshooting steps:

• No Power/Device Not Turning On: Check battery installation and ensure batteries are fresh. Replace if necessary.
• Inaccurate Readings: Ensure the sensor tip is clean and making firm, consistent contact with the measurement surface. Verify that the correct measurement mode is selected.
• Display Issues: If the screen is unresponsive or shows errors, try removing and reinserting the batteries to perform a soft reset.
• Data Transfer Problems: Ensure the USB cable is securely connected to both the meter and the computer. Verify that the necessary software or drivers are installed on your computer.

For persistent issues not resolved by these steps, please contact Fluke customer support.
