I. INTRODUCTION

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

eral condition of pumps, motors, and other machinery. Poor balance, mis-

alignment 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, and low battery. Features auto power off and an

RS232 computer interface. Comes ready to use in a foam-lined, hard-

shell carrying case, with a detachable strongly magnetic probe, 9V battery

and instructions.

III. OPERATING INSTRUCTIONS

A. GENERAL MEASUREMENT PROCEDURES

1. Attached the BNC PLUG (A11) to the BNC SOCKET (A10).

2. Attached the MINI PLUG (A12) to the INPUT SOCKET (A13).

3. a. Acceleration (ACC) Measurement:

Switch the ACC/VEL SELECTOR (A7) to the "ACC" position.

b. Velocity (VEL) Measurement:

Used for general industrial vibration. Switch the ACC/VEL

SELECTOR (A7) to the "VEL" position.

4. Switch the RMS/PEAK SELECTOR (A4) to the "RMS" position.

5. Press the POWER BUTTON (A2) once to turn on the meter.

you are testing is a non-magnetic

material, hold the VIBRATION

SENSOR and touch the tip to the

object (above).

b.If the surface material is magnetic,

connect the VIBRATION SENSOR

to the MAGNETIC BASE (left) and

touch it to the object's surface

(below).

B. PEAK VALUE

Switch the RMS/PEAK SELECTOR (A4) to the "PEAK" position.

Peak value = 1.414 RMS value.

C. DATA HOLD

1. Press the HOLD BUTTON (A3) during measurement to freeze the

displayed value. "D.H" is shown on the LCD.

2. Press the HOLD BUTTON (A3) a second time to resume

measurement.

D. DATA RECORD (Displays the Maximum and Minimum readings.)

1. To start the Data Record function, press the RECORD BUTTON (A5)

once. The LCD display will indicate "REC."

2. Press the RECALL BUTTON (A6) and the "Max" symbol (along with

the maximum value) will appear on the LCD display.

3. Press the RECALL BUTTON (A6) 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 (A5) for approximately 2 seconds. The display will revert

back to the current reading.

E. AUTOMATIC SHUT OFF

This unit has a built-in automatic shut off function to prolong battery life.

The meter will shut off 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 (A5).

F. RS232 PC SERIAL INTERFACE

The unit features an RS232 output via 3.5 mm Terminal. The connector

output is a 16 digit data stream which can be utilized by user's specific

application. An RS232 lead with the following connection will be required

to link the instrument with the PC serial input.

The 16 digit data stream will be displayed as follows:

Meter (3.5 mm jack plug) PC (9W "D" Connector)

Each digit indicates the following status:

G. 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.
