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.

Display screen
The display serves for both the A and B channel, but the items are the same,
so the following explanation covers them together.
The illustration below shows all possible functions of the display. In actual
operation, not all indicators will light up simultaneously.
CHARGE/CCLD indicator
Shows the accelerometer setting. When using a piezoelectric acceler-
ometer, select CHARGE. When using an accelerometer with integrated
preamplier, select CCLD.
SENS indicator
When the range/sensitivity readout shows the accelerometer sensitivity,
the SENS indicator lights up.
Range/sensitivity readout
Normally, this shows the range setting.
In calibration mode, the indication "CAL" is shown.
In accelerometer setup mode, the sensitivity setting is shown.

Unit indicators
Show which unit is selected.
ACC (acceleration): m/s2
VEL (velocity): mm/s
DISP (displacement): mm
HPF indicators
Show the high-pass lter setting (OFF, 10 Hz, 20 Hz, 50 Hz). OFF is
indicated by "--".
LPF indicators
Show the low-pass lter setting (1 kHz, 3 kHz, 10 kHz, OFF). OFF is
indicated by "--".

Names of Parts and Functions
Bottom Panel
To access the link connector for linking units, remove the cover plates on
the bottom of the unit. The connector is used to supply power to multiple
units.
Use the supplied link plate to join multiple units.
Top Panel
The top panel of the unit has two hooks which can be used to join multiple

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.

2. Remove the two link hooks on the top panel. Do not remove these
hooks for the unit that will be the rightmost unit as seen from the
front.
Put the screws and hooks 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.
3. For the leftmost unit as seen from the front, roll up the link cable
around the connector and push it into the empty space in the unit.
