Outline
The UV-15 is a single-channel vibration meter unit with a wide measurement
range. It supports connection of piezoelectric accelerometers, accelerom-
eters with integrated preamplier (24 V DC, 4 mA power supplied), TEDS
compliant accelerometers with integrated preamplier, and accelerometers
connected via the Preamplier VP-26A. The chassis of up to 16 units can be
linked to create a multi-channel conguration.
Two types of input connectors are provided (Microdot and 7-pin), and the
unit is equipped with a backlight LCD panel, alarm LEDs, operation keys,
AC and DC output connectors (BNC), DC IN jack, and link connector.
The following accessories are available as options, allowing the conguration
of advanced measurement systems suited to various requirements.
Sound level Meter Unit UN-14
Single-channel sound level meter unit designed for connection of a
measurement preamplier microphone.
In combination with the UV-15, a multi-channel sound and vibration
level measurement system can be congured.
AC adaptor NC-99 series (CE mark), NC-97 series
AC adaptor supplies the UV-15 with the DC power.
It also can supply linked multiple unit with the DC power.
Battery Unit BP-17
Designed to hold eight IEC R14 (size C) batteries, this unit can be
linked to the UN-14 and/or UV-15 to provide power.
The power switch on the front panel of the BP-17 can be used to switch
the entire system on and off.

Interface Unit UV-22
Linking the UV-22 allows connection to a computer for controlling
the sound and vibration level measurement system and for transfer
of measurement data.
Both USB and Ethernet connections are supported.
