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)
Center Pin Pin 2
Ground/Shield Pin 5

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.
