TABLE OF CONTENTS

INTRODUCTION

The level of vibration is a useful guide to the balance, alignment

and general condition of pumps, motors, and other machinery. Poor

balance, misalignment and looseness results in higher levels of

vibration and indicates maintenance is required for operational as

well as safety reasons.

Measures velocity and acceleration. The large display indicates

RMS, Peak, min-max, hold, low battery, and auto power o󰀨. Comes

ready to use in a foam-lined, hard-shell carrying case, with a

detachable strongly magnetic probe, 9V battery and instructions.

OPERATING INSTRUCTIONS

General Measurement

1. Attached the BNC PLUG to the BNC SOCKET.

2. Attached the MINI PLUG to the INPUT SOCKET.

3. a. Acceleration (ACC) Measurement:

Awitch the ACC/VEL SELECTOR to the “ACC” position.

b. Velocity (VEL) Measurement:

Used for general industrial vibration. Switch the ACC/VEL

SELECTOR to the “VEL” position.

4. Switch the RMS/PEAK SELECTOR to the “RMS” position.

5. Press the POWER BUTTON once to turn on the meter.

6 If the surface material of the object you are testing is a

non-magnetic material, hold the VIBRATION SENSOR

and touch the tip to the object.

If the surface material is magnetic, connect the VIBRATION

SENSOR to the MAGNETIC BASE and touch it to the

object’s surface.

Peak Value

Switch the RMS/PEAK SELECTOR to the “PEAK” position.

Peak value = 1.414 RMS value.

Data Hold

1. Press the HOLD BUTTON during measurement to

freeze the displayed value. “D.H” is shown on the LCD.

2. Press the HOLD BUTTON a second time to

resume measurement.

Data Record

(Displays the Maximum and Minimum readings.)

1. To start the Data Record function, press the RECORD BUTTON

once. The LCD display will indicate “REC.”

2. Press the RECALL BUTTON and the “Max” symbol (along with

the maximum value) will appear on the LCD display.

3. Press the RECALL BUTTON again and the “Min” symbol (along

with the minimum value) will appear on the display.

4. To exit the memory record function, press and hold the

RECORD BUTTON for approximately 2 seconds. The display

will revert back to the current reading.

Automatic Shut O󰀨

This unit has a built-in automatic shut o󰀨 function to prolong

battery life. The meter will shut o󰀨 automatically if no buttons are

pressed within 10 minutes. To deactivate this feature, select the

memory record function during measurement, by pressing the

RECORD BUTTON.

BATTERY REPLACEMENT

When the top left corner of LCD display indicates “LBT,” it is time

to replace the battery. Accurate readings may be taken for several

hours after the low battery indicator appears. Open the battery

cover, install a fresh 9V battery and replace the cover.
