Outline
The UV-16 is a two-channel charge ampli er for vibration measurements using
piezoelectric accelerometers or accelerometers with integrated preampli er.
By linking the chassis of up to 16 units, a multi-channel con guration with
up to 32 channels is possible. The main unit is equipped with an LCD panel,
alarm LEDs, operation panel, input connectors (micro-dot), output connec-
tors (BNC), DC IN jack, and link connector.
Power is supplied by the optional AC adapter NC-97 series (up to 10 UV-16
units), or NC-99 series (up to 16 UV-16 units) (CE mark). In con gurations
with a low number of channels (up to 3 units), the dedicated Battery Unit
BP-17 (option) with 8 IEC R14 (size C) batteries can also be used.

Linking
Multiple UV-16 units can be linked to form a multi-channel system.
The maximum number of units that can be linked is 16 (resulting in
32 channels).
When using the Battery Unit BP-17 to power the units, the maximum number
of units that can be linked is three.
Required tool: 1 Phillips screwdriver (JIS B 4633:1998, type H, No. 2)
Important
Precautions for linking units
Make sure that power is OFF before starting:
•
• Disconnect AC adapter.
• When using Battery Unit BP-17: Remove
batteries
Do not use any screws other than the ones
•
supplied with the product.
Do not insert any objects (pieces of metal,
•
pencil lead, etc.) into the unit.
Use only the speci ed screwdriver (Phillips
•
screwdriver, JIS B 4633:1998, type H, No.
2). Otherwise the cross-shaped slots on the
screw heads may be damaged.
Linking procedure
1.
Remove the 4 screws holding the cover plates on the bottom of the unit, and
remove the cover plates. Do this for all units that are to be connected.
Put the screws and cover plates in a box or other suitable container, to
make sure that you do not lose any parts. The parts will be required
later for reassembly.

stabilize the unit when it is used in a free-standing con guration.
Use the screws removed from the unit.
Why not to use other screws:
Too short screws will not properly secure the plate.
Too long screws may damage parts inside the unit.
1. Remove two screws from the cover plates on the bottom of the unit
(the two screws that are nearer to the front side). Refer to the left-side

Power Supply Connection
The UV-16 can be powered from an AC adapter (option), the Battery Unit
BP-17 (option), or a car battery (12 V).
The UV-16 does not have a power switch. It will start to operate when power
is supplied.
The Battery Unit BP-17 (option) has a power switch which allows shutting
down the system.
Important
When using multiple units in a linked con guration, make sure that system assembly is fully
completed before supplying power.
Power supply limitations
Power supply type Max. number of units
AC adapter (option) NC-97 series Up to 10
NC-99 series (CE mark) Up to 16
Battery Unit BP-17 (option) IEC R14 (size C) battery × 8 Up to 3
Note
The display backlight is always on when the unit is
powered from an AC adapter. When the unit is powered from batteries using the Battery Unit BP-17, the
display backlight is activated for 10 seconds when
any key is pressed.
To power a system in which the Battery Unit BP-17
is installed from an AC adapter, be sure to connect
the AC adapter to the BP-17.
The UV-16 does not have a power switch. It will start
to operate when power is supplied.
17
Power Supply Connection
Using an AC adapter
If no Battery Unit BP-17 is installed in the system, the AC adapter may be
connected to any UV-16 unit.
Caution
Be sure to use only a single AC adapter to
power a linked system consisting of multiple Two-Channel Charge Ampli er UV-16
units.
Important
Do not use any AC adapter other than the
speci ed models. Otherwise malfunction and
damage may occur.

When the lower LED is ashing in red, correct
measurement is no longer possible.
Before replacing the batteries, be sure to set
the power switch to OFF (press

When inserting batteries, take care not to mix
up "+" and "−" polarity.
Always replace all eight batteries together. Using a
mixture of old and new batteries or batteries of a different type can lead to malfunction and damage.
When not using the unit, remove the batteries to guard
against the risk of damage by leaking battery uid.
When powering a system from batteries using
the BP-17, the maximum number of UV-16 units
that can be linked is three.
19
Power Supply Connection
The Battery Unit BP-17 has a DC IN jack on the rear panel. To power the
system from an optional AC adapter, connect the adapter to this jack.

Accelerometer Mounting
The UV-16 is a vibration measurement ampli er designed for use with
piezoelectric accelerometer or accelerometer with integrated preampli er.
Other types of accelerometers such as electrokinetic accelerometers cannot
be used with this product. Choose a suitable accelerometer according to the
measurement requirements including measurement range, frequency range,
and environmental conditions. The accelerometer mounting method has a
signi cant effect on the reliability of measurement data, and it will greatly
affect the contact resonance frequency. The advantages and disadvantages
of various mounting methods are outlined below. Refer to this information
when making your selection.
Accelerometer Selection and Connection
Rigid screw mounting
This mounting principle assures optimum frequency response characteristics. The mounting
surface should be perfectly smooth, and the screw
holes must be drilled in such a way as to assure
perfect perpendicularity of the accelerometer.
Insulation attachment mounting
This mounting principle is used when electrical
insulation between accelerometer and measurement object is required. The contact resonance
frequency will be lower than with rigid screw
mounting. Regarding the screw holes, the same
precautions as for rigid screw mounting apply.
Magnet attachment mounting
Because the contact resonance frequency will
be quite low, this principle is mainly suited for
vibration measurements in the medium to low
frequency range. The maximum acceleration that
can be measured depends on the accelerometer
mass.

Rod attachment mounting
Pressing the accelerometer against the measurement object with a rod is the simplest method,
but the measurement frequency range would be
about several hundred Hz, because the contact
resonance frequency will be very low. This
method should only be used if none of the other
three mounting methods are feasible.

WARNING
When performing measurements on machinery with exposed rotating parts or
drive train parts, proceed with utmost
caution to avoid the risk of getting caught
in the machinery.
Note
Tighten the M6 screw rst on the piezoelectric accelerometer side and then mount the rod attachment.

Output Connections
The rear panel of the UV-16 provides one AC output connector each for
channel A and channel B. This signal can be supplied for example to an
oscilloscope for waveform observation, to a data recorder for recording, or
to an FFT analyzer for analysis. The calibration signal (see page 35) is also
output from this connector.

Changing the range setting
To change the range setting, use the RANGE / keys.
If the signal from the accelerometer is too high for the selected range, the
internal ampli cation circuits will saturate, causing the overload indica-
tor LED to light up. In such a case, correct measurement is not possible,
and you should change the range setting.

[Usage precautions]
When the measurement mode is set to velocity, the following point should
be observed.
The degree by which the inherent noise of the unit (noise generated in
the measurement device itself) affects the vibration velocity measurement
depends on the sensitivity setting of the piezoelectric accelerometer and
the range setting of the unit. Under the following conditions listed below
the inherent noise reaches maximum.
Measurement mode: Velocity
Sensitivity and range setting:
Sensitivity setting 0.100 to 0.250, range setting 10 (minimum range)
Sensitivity setting 1.00 to 2.50, range setting 1 (minimum range)
Sensitivity setting 10.0 to 25.0, range setting 0.1 (minimum range)
HPF : OFF
Under the above conditions, you should increase the range setting by one
32
increment, or set the internal high-pass lter to 10 Hz or higher, in order
to reduce the in uence of inherent noise.
