Note
Operating Precautions
- Operate the unit only as described in this manual.
- Do not disassemble or modify the unit.
- In the vicinity of a strong magnetic eld (such as produced by magnets, motors,
speakers, etc.), measurement results may be affected.
- The calibration exciter in the unit uses a semipermanent magnet. If cassette tapes,
oppy disks, watches or similar are placed close to the unit, erasure or faulty opera-
tion may result.
- This is a precision device. Protect it from shocks.
- If the specied torque (0.1 N·m to 0.2 N·m) is exceeded when fastening the vibration
pickup, the exciter spring may sustain permanent damage.
- In case of malfunction, do not any attempt any repairs. Note the condition of the
unit clearly and contact the supplier.

Outline
The VE-10 is a portable vibration exciter designed for calibration of vibration pickup, vibra-
tion meter, vibration measurement system, etc.
The VE-10 generates a sinusoidal vibration of 10 m/s2(rms) in acceleration, 10 mm/s (rms)
in velocity, 10 μm (rms) in displacement.

Loading Battery
1. Turn the bottom case counterclockwise and
take it off.
2. With the correct polarity, attach a 6LR61
alkaline battery to the battery connector.
3. Insert the battery in the battery compart-
ment.
4. Screw the bottom case on the unit.
Note
If continuous mode cannot be activated, or if
the unit does not respond when the Power/Mode
switch is pressed, replace the battery with fresh
one.

Attaching Vibration Pickup
Attach the vibration pickup to the VE-10 with one
of the following methods, and connect the pickup
to the input connector of vibration meter using a
low-noise cable.
Torque for fastening the vibration pickup and adapter
will be 0.1 N.m to 0.2 N.m; tighten lightly by hand.
Pickup with M3 screw hole
1. Attach the vibration pickup to the adapter
with the M3 screw.
2. Mount the adapter on the exciter of the
VE-10.
Note
If the specied torque (0.1 N.m to 0.2 N.m) is
exceeded when fastening the vibration pickup, the
exciter spring may sustain permanent damage.

Vibration Pickup with UNF screw hole
1. Attach the M6-UNF screw (UNF side) to the
vibration pickup.
2. Mount the vibration pickup on the exciter using
the M6 side of M6-UNF screw.
＊Precautionstoensurecorrectcalibrationresults
・When mounting pickups with a weight of less
than 10 g, use the supplied adapter (weight about
12 g) or another suitable weight to bring the total
weight to 10 g or more.
・Do not use vibration pickups with a weight of more
than 70 g (including adapter and connection cable
etc.). This is especially important when calibrating
products such as the PV-57A or PV-57I that can exceed 70 g depending on cabling.
For information on pickup weight, refer to the catalog, specications, or other docu-
mentation about the pickup.

Calibration
The VE-10 should be in the soft case when performing calibration. Also, do not give vibra-
tions to the VE-10 especially when calibrating in velocity and displacement.
Calibration of Vibration Measurement System
1. Set the sensitivity of the vibration meter to the sensitivity of the vibration pickup
in use.
2. Set the measurement range of the vibration meter to measure 10 m/s2(rms) for ac-
celeration, 10 mm/s (rms) for velocity, or 10 m (rms) for displacement.
3. Press once the power/mode switch. The power indicator lights up, and the VE-10
generates a sinusoidal vibration of 10 m/s2(rms) in acceleration, 10 mm/s (rms) in
velocity, 10 m (rms) in displacement.
4. After at least ve seconds have elapsed, verify that the indication of the vibration
meter has stabilized, and then check the measurement values in the respective mea-
surement modes. If the meter does not show the correct value, adjust the sensitivity
setting.

Sensitivity Check of Accelerometer
1. Set the sensitivity of the meter to the sensitivity of the accelerometer.
2. Set the measurement range of the vibration meter to measure 10 m/s2(rms) for ac-
celeration.
3. Press once the power/mode switch. The power indicator lights up.
4. After at ve seconds have elapsed, verify that the indication of the vibration meter
has stabilized, and then adjust the sensitivity control of the meter so that the meter
indicates 10 m/s2(rms). The reading of the sensitivity control shows the correct
sensitivity of the accelerometer in pC/(m/s2).
