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.
5
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.
