Preamble

2.1

Product Description

The EZE22 is an amplifier which processes analogous signals and converts these signals into digital
measured values. These measured data can be retrieved by the PC by means of the USB-Interface. The
current supply occurs via a separate power supply which is included in delivery.
 Required output voltage:
 Required power supply:
The EZE22 is suitable for the connection and simultaneous value acquisition of two sensors. Depending
on the EZE22 model, respectively four different types of sensor signals can be captured (for
specifications see data sheet):
 SG- Signals:
 Active Signals with Voltage Input:
 Active Signals with Voltage Input:
 Active Signals with Current Input:
The amplifier type and the resolution are stated on the type label, a type change is only possible by the
manufacturer. Hence, only the corresponding sensor type can be connected.
Please consider the signal type. The connection of a wrong signal type can lead to damages.
The measured values are issued in digits (16 bit signed integer format) with leading signs (see above in
brackets).
If the EZE22 is adjusted to a specific sensor, the output value will be stated on the test certificate.
If the EZE22 is not adjusted to a specific sensor, the output values are adjusted as stated above (in
brackets). In this case, the output values are adjusted with a high-precise reference.
The evaluation occurs by the LCV-USB-VS2 software which contains following functions:.
 Configuration possibilities for the LCV-USB-VS2
 Storage of sensor-related scaling and adjustment data
 Display for the presentation of measured data (actual value, tare value, minimal value and
maximal value)
 Presentation of the measured data in a diagram
 Storage of measured data in CSV-format (output configurable)
 Storage of the diagram in BMP-format (output size adjustable)
 Print-out of the diagram (output size defined)
 Presentation of the sensor information
The communication protocol is described in document no. 090110, "A flexible command set for digital
sensors and interfaces" which states how to activate the EZE22 through own software.

Safe and Correct Use

Consider the correct sensor adjustment.
Consider the correct LCV-USB-VS2 configuration.
Choose a significant file identification/prefix when storing measured data.
Fasten housing, ground, connect power supply, protect from splash water and do not pull the
cable.
