Product Overview

INTRODUCTION

The Fluke 930 Tachometer and the Fluke 931 Tachometer (the Tachometer) are hand-held instruments that accurately measure rotational Revolutions Per Minute (RPM). The Fluke 931 measures surface speed as well as length. Use the red beam function to make non-contact RPM measurements. The Fluke 931 uses the mechanical adapter and selectable tip to make contact RPM measurements. The Memory function allows storing the maximum (MAX), minimum (MIN), average (AV), and last reading.

THE KEYPAD

The Tachometer turns OFF after 30 seconds of inactivity.

| Selects the Measurement function

THE DISPLAY

OPERATION

Press to power up the Tachometer. The display test illuminates all LCD segments for 1 second and then shows the configured surface speed selection.

• The last selected mode appears at when the Tachometer is turned ON.
• The Tachometer automatically turns OFF after 30 seconds of inactivity.

CONFIGURATION (FLUKE 931)

To configure the Tachometer for the correct contact wheel used for surface speed measurements:

1. Turn ON the Tachometer.
2. Press and release.
3. Use F to select 0.1 (0.1 m circumference small wheel) or 6” (6 inch circumference large wheel). A 12” wheel is not available.

OPTICAL (NON-CONTACT)

To measure RPM using the non-contact red beam, remove the mechanical adapter from the top of Tachometer. Pull the adapter straight out to remove. See Figure 2.

1. Stop the rotating device to measure.
2. Clean a spot for the reflective strip.
3. Place reflective strip on rotating device.
4. Turn ON the Tachometer.
5. On the Fluke 931 use to select RPM.
6. Aim Tachometer at rotating reflective strip keeping within 500 mm (20 inches).
7. Press to enable the red beam.
8. When the Tachometer is triggered by the reflective strip, the trigger symbol on the display flashes and RPM will be displayed.

CONTACT (FLUKE 931)

To use the Tachometer for contact measurement, insert the mechanical adapter into top of the Tachometer, see Figure 1:

1. To measure, connect the cone or internal cone shaft contact to the end of the shaft.
2. Turn ON the Tachometer and use to select RPM .
3. Press to take measurements.
4. When the Tachometer is triggered, the trigger symbol flashes and the RPM is displayed.

SURFACE SPEED AND LENGTH (FLUKE 931)

Surface speed and length can be measured using the mechanical adapter and contact wheel.

CONTACT WHEEL USE (FLUKE 931)

1. Insert mechanical adapter into the top of the Tachometer. See Figure 1.
2. Select either the 0.1 m or 6 in contact wheel to use.
3. Set the Tachometer to 0.1 m or 6 in setting for the contact wheel in use.
4. Use to select units of measure.
5. Contact wheel to surface to measure and press to take measurements.
6. When the Tachometer is triggered, the trigger symbol flashes and the measurement is displayed.

MAX, MIN, AND AV READINGS

Press to enable MAX, MIN, and AV readings stored in memory. Each time a new measurement is taken, the maximum, minimum, average, and last value are stored. The last value is shown under MEM. The units of measure for the stored readings will also be displayed. Press O to exit the memory display mode.

MAINTENANCE

Beyond replacing the batteries, do not attempt to repair or service the Product unless you are qualified to do so and have relevant calibration, performance test, and service instructions. The recommended calibration cycle is 12 months.
