1.2 Included Parts
Following parts are included:
• 1 Plug.n.DAQ Lite 2 Channel or 1 Channel version IEPE DAQ
• 1 USB-cable
1.3 Safety Information– read before use!
Caution: The unit is only suitable for low voltage measurements. Under no circumstance should
voltages (AC or DC) above 40 Volt peak be connected to any input or output. Please enable the IEPE
supply only while an IEPE compatible sensor is connected to that input, as other devices may be destroyed
by the IEPE voltage of up to 28V.
The IEPE supply may also cause interference if there is no sensor connected.

2.2 Installation
Start your PC. Microsoft Windows ME, Windows 2000, Windows XP or above should be installed. These
operating systems do not require additional drivers. The Plug.n.DAQ Lite will be automatically detected and
installed as USB-Audio-Device.
You may now use your Plug.n.DAQ Lite with any software supporting Windows PC soundcards.
3. Making Measurements
3.1 Scaling
The maximum values represent the maximum input range (e.g. +32.767 = 5V;-32.768 = -5V). The input
range is defined as peak voltage, not rms.
Not all software applications detect the supported sampling rates properly. Please make sure to only
use the supported sampling rates as outlined in the specifications section.
3.3 Setup & Sensor supply
As first make sure that the Plug.n.DAQ Lite is enabled for two channel mode in the sound card properties:
