Designation and technical specifications Introduction The present User manual describes structure and operating principles if digital inclinometers of ZET 7х54 series (hereinafter referred to as “inclinometers”). The document contains general rules of inclinometers operation as well as instructions concerning installation, start-up and maintenance activities.
Designation of inclinometers Inclinometers are used for measurement (by two mutually transverse axes X and Y) of tilt angle of buildings, structures or controlled structural elements. The most popular spheres of use of inclinometers are as follows: 1. Platforms position and alignment control; 2.
Technical specifications Basic technical characteristics of the inclinometers are specified in Table 1.2 Table 1.2 Technical specifications of ZET 7x54 Значение Value Parameter ZET 7054 ZET 7154 ZET 7054 ZET 7154 Measured physical value Tilt angle Number of measurement axes 2 (X and Y) Measurement range, °...

Digital inclinometers: mounting It is possible to mount the inclinometers directly to the controlled surface (the inclinometer package has 4 mounting holes with 4,5 mm diameter). In order to provide the possibility of inclinometer adjustment by azimuth and horizon, one can use the adjustment plate for mounting of the inclinometer (Figure 2.6).
Establishing measuring network: connection diagram In the course of measuring network development, digital transducers ZET 7x54 are connected sequentially. The resulting measuring network of digital transducers is further connected to the PC by means of interface converter (Table 3.1). Figure 2.7 displays the measuring network based on digital transducers ZET 7154.
To select the digital transducer to be configured, double-click its name. (Additional information is available in the document “ZETLAB Software. User manual”). The program “Device manager” available in the “Service” menu of ZETLAB control panel is used for adjustment and configuration of the inclinometers.
«Axis X», «Axis Y»), corresponding to the two measuring axes. When assigning the addresses, please note that the channels of digital transducers ZET 7154 have two addresses in the measuring network, while the channels of digital transducers ZET 7054 are assigned a common address.
Functions and composition of the tabs used for configuration of measuring part of the digital inclinometers Digital transducer consists of two channels (by default, the names of the channels are: “Axis X” and “Axis Y”). It is possible to configure parameters of the digital transducer only in the tab of the channel “Axis X”.

5 minutes of program operation. For inclinometers ZET 7154, it is possible to control the data quality and the synchronization quality, while inclinometers ZET 7054 have only the function of data quality control. shows an example of the program “Synchronization control”.
Metrological self-check Inclinometers ZET 7154 have a function of metrological self-check. A reference signal is applied to the sensing element of the inclinometer in order to imitate the change of tilt angle at a particular value. The deviation of the measured value from the reference one is used to evaluate the metrological reliability of the inclinometer.
