Outline
The UV-22 is a dedicated interface unit for use with the Sound Level Meter
Unit UN-14 and Vibration Meter Unit UV-15. Up to 16 UN-14 and UV-15
units can be linked to a single UV-22. Both USB and Ethernet (LAN) in-
terfaces are provided for connection of the UV-22 to a computer, allowing
setup, measurement control, and data retrieval for the UN-14 and UV-15
from the computer.
The supplied UV-22Viewer software makes it easy to establish settings for
the UN-14 and UV-15 and display measurement results on the computer. User
lter settings *1for the UN-14/UV-15 can also be made.
The Master/Slave function *2of the UN-14/UV-15 is supported as well, which
simplies operation of multiple units.
*1 User lter
One cutoff frequency as specified below can be added by the user to
the factory default high-pass filter and low-pass filter settings of the
UN-14/UV-15.
Cutoff frequency (UV-15: −10% attenuation, UN-14: −3 dB attenuation)
HPF: 3 Hz, 3.15 Hz, 4 Hz, 5 Hz, 6.3 Hz, 8 Hz, 10 Hz, 12.5 Hz, 15 Hz,
16 Hz, 20 Hz, 25 Hz, 30 Hz, 31.5 Hz, 40 Hz, 50 Hz, 63 Hz, 80 Hz,
100 Hz, 125 Hz, 150 Hz, 160 Hz.
Attenuation slope: −18 dB/oct
LPF: 300 Hz, 315 Hz, 400 Hz, 500 Hz, 630 Hz, 800 Hz, 1 kHz, 1.25 kHz,
1.5 kHz, 1.6 kHz, 2 kHz, 2.5 kHz, 3 kHz, 3.15 kHz, 4 kHz, 5 kHz,
6.3 kHz, 8 kHz, 10 kHz, 12.5 kHz, 15 kHz, 16 kHz, 20 kHz (25 kHz,
31.5 kHz, 40 kHz, 50 kHz).
Settings in brackets are for UN-14 only.
Attenuation slope: −18 dB/oct
Frequency response characteristics for the high-pass lter and low-pass lter
are shown in the “Reference Material” section (from page 66).

*2 Master/Slave function
When multiple UN-14 or UV-15 units are linked, the settings of other
units (Slave units) can be changed from one unit (Master unit) using this
function.
For example, if you set one UN-14 (Master unit) to CAL (calibration)
mode using a special key action, all other UN-14 units (Slave units) will
also go into calibration mode. (To do this, you simply need to press and
hold the CAL key on the unit you want to use as Master unit.)
The following optional equipment is available.
- Sound Level Meter Unit UN-14
Single-channel sound level meter unit supporting the connection of a
measurement microphone with preamplier.
- Vibration Meter Unit UV-15
Single-channel vibration meter unit supporting the connection of an
accelerometer.

To use USB for the connection to a computer, plug the USB cable into
this connector.
The connector on the cable must be a mini-B type.
If using USB for the rst time, the USB driver must be installed on
the computer.
POWER switch
Set to ON to activate the unit.
If an AC adapter is connected to the UV-22, setting the POWER switch
to ON will also supply power to the linked UN-14/UV-15 units.
When using the Battery Unit BP-17, connect the AC adapter to the
BP-17 and leave the POWER switch of the UV-22 set to ON. Power
on/off then is controlled with the power switch of the BP-17.

Linking
Install the Interface Unit UV-22 in the leftmost position of a
linked series of units as seen from the front.
Required tool:
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

Linking
Linking procedure
1. 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.
2. Plug the link connector of each unit into the link connector of the
next unit.

3. After plugging in the link connectors, use the link plates supplied with
the UN-14/UV-15 and the screws removed in step 1 to provisionally
join the units as shown below.
Be sure to use the screws removed in step 1.
Why not to use other screws:
Too short screws will not properly secure the plate.
Too long screws may damage parts inside the unit.
4. Attach the link hooks removed in step 1 to the unit tops, so that the
units are locked together.
