1.3. Installation Notes
tecsis GmbH devices must be installed and connected by compliance with the relevant DIN- and VDE-
norms. They must be installed in such manner that an unintentional use is adequately excluded. The
corresponding hardware and software safety precautions are to be observed in such manner that an
interruption of the supply and signal cables cannot lead to an undefined or dangerous state. Supply and
signal cables must be installed in such way, that disturbing signals (e.g. inductive or capacitive
intersperses) will not cause derogations to the function of tecsis GmbH devices.
1.3.1 Disturbance, M aintenance and Repair Notes
The devices do not contain parts which can be maintained on the customer side. Repairs shall be carried
out by tecsis GmbH exclusively.
If assuming that a safe operation of the device is not possible anymore, it must be closed down and
protected against unintentional handling immediately. This, in particular, applies:
If the device shows visible damages
If the device is no longer operative
If parts of the device are loose or slack
If the connection cables show visible damages
Furthermore, we point out that all obligations of tecsis GmbH exclusively result from the respective sales
contract in which the guarantee has been conclusively settled.
2. Preamble
2.1 Product Description
The EZE21 is a measurement amplifier for the conversion of analog signals into digital measured values.
These measured data can be requested through the Computer via the USB-interface.
The EZE21 is supplied from the USB-interface. No external mains adaptor is needed.
The EZE21 is designed for 4 types of sensor signals (specifications see datasheet):
strain gauge signals:
±3mV/V
(corresponding to ±30000 Digits)
active signals with voltage input: ±5V
(corresponding to ±25000 Digits)
active signals with voltage input: ±10V
(corresponding to ±25000 Digits)
active signals with current input: 0 ..
20mA
(corresponding to 0
.. +
20000 Digits)
The amplifier type and the resolution are declared on the type label, a type modification is only authorized
by the manufacturer. Therefore only the corresponding sensor type may be connected.
The measuring data are signed in integer format (see above in brackets).
If the EZE21 is calibrated together with the sensor, you can take the output values from the test
certificate.
If the EZE21 is calibrated without a sensor, you can take the output values as described above in
brackets. They are pre calibrated with a high precision source.
The measuring data can be analyzed with the VASUSB Software. This software supports the following
functions:
Configuration possibilities for the VASUSB
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
