Coding ...
... or, "How are the measurement locations in the data base linked to the measurement locations onsite on the machine?"
The coding of the “mechanical” measurement locations is defined in the measurement location data base using the OMNITREND software and stamped into a special plastic ring using a tool. The coded ring is installed on the machine together with the measuring pin. This forms the link between the data base and the machine.
VIBCODE concept
... or, "What is the difference between a route and a pool?"
A machine park contains many VIBCODE measurement locations.
However, not all measurement locations are measured with the same frequency since they are assigned different roles in the data base.
Thus, the VIBCODE concept is structured as follows:
A: VIBCODE route
VIBCODE measurement locations at which measurements are taken regularly are part of a route. Because each route is created for a particular purpose (e.g. weekly inspection), it only contains a certain subset of all VIBCODE measurement locations. VIBCODE features automatic measurement location recognition so that the measure-ment locations can be visited in any order.
B: VIBCODE pool
A “pool” contains additional measurement locations that are mea-sured on a route only if there is a special need. Pool measurement locations are loaded into the data collector together with the corresponding route.
C: Unknown VIBCODE measurement location
If the VIBCODE sensor is connected to a measurement location that is contained neither in the current route nor in an associated pool, VIBXPERT interrupts the route. A measurement can only be per-formed in the ‘Multimode’ (see also next page).

Attention!
Measuring with VIBCODE
Never use the VIBCODE sensor to take a measurement directly from the machine surface. This sensor must always be locked onto the measuring pin!
Do not remove the VIBCODE sensor neither from the VIBCODE measurement location nor from VIBXPERT during measurement.
Connecting the VIBCODE sensor*
Insert the sensor straight into the measurement location, press it in place lightly and lock it by turning it clockwise until it stops.
This secure connection ensures that the measurement direction and pressure are the same for each measurement and that the results are reproducible.
To disconnect the sensor, turn it in the opposite direction and remove it from the measurement location.
Connect the sensor cable to the measurement channel that is set in the measurement task (A or B).

Measuring VIBCODE Route/ Pool
• Click on ‘Route’ in the start screen.
• Open the route to be measured.
• Connect the VIBCODE sensor to a VIBCODE measurement loca-tion:
VIBXPERT reads the coding of the measurement location and checks if this is created in the route. If VIBXPERT finds a measurement task, measurement starts automatically. If all measurement tasks at the measurement location are complete, plug the VIBCODE sensor into the next VIBCODE measurement location and continue measurement of the route.
If VIBXPERT finds the measurement location in the VIBCODE pool, the measurement task scheduled first starts automatically. All other measurements must be triggered manually via the measurement task selection.
To return to route mode from pool mode, press the MENU button and click on ‘Route’.
If the VIBCODE measurement location is not contained in either the route or in the pool, change to the ‘Multimode’ mode to perform the required measurement. To do so, click on 'Multimode' in the message window or press the MENU button and click on ‘Multimode’. Under certain circumstances it may be necessary to change the transducer in the task manager to ‘VIBCODE’ beforehand. After saving the measurement result, repeatedly press the ESC button to return to the route mode.

Technical notes
VIBXPERT is a precision instrument and should be treated as such.
Storage
Use the VIBXPERT carrying pouch for transporting VIBXPERT and for making on-site measurements. If VIBXPERT is not used for lengthy periods, stow the measurement instrument in the pouch and connect it regularly to the mains to avoid the battery from completely discharging.
Make sure that
- the storage location is dry
- the measurement device is not stored near electronic equipment which can generate strong electromagnetic fields.
- the measurement instrument is not exposed to temperatures above 70°C / 156°F or under -20°C /-4°F.
- the humidity is not more than 90%.
Cleaning
If lightly soiled, the carrying case and the housing can be wiped with a damp cloth. In cases of more stubborn soiling, use a household cleaner.
The display is protected against damage by a scratch-free transparent film. Use a soft dry cloth to clean the film. If necessary, the protective film can be ordered from your PRÜFTECHNIK representative.
Never use solvents or other strong cleaning agents
Maintenance & Calibration
Various factors such as aging or temperature can cause an offset in the analog electronics. This offset should be compensated every two months. Details are given on page 2-29.
To guarantee the high measurement accuracy of the device, VIB-XPERT requires calibration every two years. The calibration date is indicated on the colored sticker on the rear of the measurement instrument. A couple of months before the next calibration a warning will appear on the display when the instrument is switched on. Send the device to your PRÜFTECHNIK representative for calibration.
