Description
Power supply
The VIBSCANNER is supplied with a NiMH battery that ischarged by a battery charger (VIB 5.420). During thecharging process, the VIBSCANNER is switched off and thebattery remains inside the instrument. Reserve batteriescan also be charged outside the instrument.
The NiMH battery loses 1- 2% of its charge (self-discharge) per day when the VIBSCANNER is switchedoff. If you do not need the VIBSCANNER for a longerperiod of time (> 3-4 weeks), please remove thebattery and leave it connected to the charger (not inthe intrinsically safe version). Before you reinsert it,recharge the battery.
When VIBSCANNER is switched on and the batterycharger is connected, the charging process is interrupt-ed and...
VIBSCANNER is supplied with mains power. VIBSCANNER (intrinsically safe) is supplied with
battery power.
Measurements are not allowed with the charger con-nected because this can result in measurement errors.
After approx. 10 minutes, the VIBSCANNER loses thetime and date setting if the battery is removed.
Rechargeable batteries must not be charged in explo-sive environments!
Charging the battery Open the protective cap on the battery. Connect the battery charger to the battery and to the
power supply.
Before charging, the battery should be discharged as muchas possible. The maximum charging time is approx. 6 hours(approx. 10 hours for intr. safe battery).

Protective cap Level of chargeLED (red, green)
Operating state during charging
The charge level of the batteries is indicated by two LEDs:
Red lights up: battery is being charged Green lights up: battery is charged Red flashes: battery is defective or initialization (only
beginning to charge; can flash for several minutes).
Description
Charge level of the battery
The charge level of the battery appears at the bottom rightof the VIBSCANNER display:
Level of charge(black= battery full)
Even if the battery exhibits only a very slight memoryeffect, it should only be charged when it is completelydischarged. Otherwise, the display of the charge level canvary from the actual charging status after several incom-plete charging cycles and the following message appears:
Information: BATTERY LEVEL INACCURATE!The battery level display may be inaccurate....

Description
In order for the display to show the actual charge level ofthe battery again, proceed as follows:
Leave the VIBSCANNER switched on until the battery isalmost fully discharged when the message appears:
Battery empty
If the message appears during a measurement, youhave approximately another 30 minutes time to termi-nate your work and save the data.
Recharge the battery again.When the VIBSCANNER is switched on, the messageBattery level inaccurate... appears again.
Discharge the battery again as described above, andrecharge it again.Only when this step has been completed is the display ofthe charge level correct.
Handling VIBSCANNER batteries correctly1. Never deeply discharge the batteryIf the battery is nearly empty, VIBSCANNER automaticallyswitches off to avoid deeply discharging the batteries. Sincea low residual current flows even when the battery isswitched off, the battery should be taken out of theinstrument if it is to be stored for a lengthy period of timeand charged at regular intervals (1 month) to avoid acomplete self-discharge.
2. Charge and discharge the battery completely:Repeated incomplete discharging/charging leads to a re-duction of the battery capacity through the so-calledmemory effect and to an imprecise loading status display.However, this can be remedied by a number of completecharging and discharging cycles (Battery empty).
3. Store the battery in a cool placeThe self-discharge of the batteries increases greatly athigher temperatures. Therefore, the battery should bestored as cool as possible (0-25C) or, if the storagetemperatures are higher, it should be recharged moreoften. Batteries that are not intrinsically safe should alwaysbe connected to the charger during charging (conservationcharging)

Enter the parameters required for normalization of themeasured values. The Mode parameter can be set byrepeatedly pressing the joystick.
If you do not want to make normalized measurements,set the Mode parameter to No normalization.
The RPM and shaft diameter determine the initialvalue (dBi). External influences on the signal are takeninto account in the adapted value, dBa. Both factorsresult in the adapted initial value, dBia:
dBia = dBi(RPM; ) + dBa

The RPM at any measurement location can be calculatedfrom the line speed in a production line (e.g. papermachine, conveyor belt,...) and the diameter of the in-dividual bearings. In addition, the different RPM conditions(e.g. due to gears, slip,...) are taken into account for eachbearing (see previous section Aggregate RPM).
The bearing diameter and RPM conditions are set up inOMNITREND, and the production line speed is entered inVIBSCANNER before the measurement on site.

e. To carry out permanent measurementsIf you hold down the joystick after starting the measure-ment, VIBSCANNER measures permanently without car-rying out any averaging. Only when you leave go of thejoystick does the actual measurement begin with theselected averaging number.Application example: Initially, heavily fluctuating valuesare measured on a machine that stabilize after a certainamount of time. This measurement function lets youtrace the incoming values on the screen and to startrecording the data only when the values have stabilized.
f. Signal check (2-channel measurement)To check the signal before a measurement with theautomatic switchbox (VIB 5.446) on each channel (A/B), proceed as follows:
Activate the Display channel A/B display option inthe device setup (see page 19).
Click on AB in the Setup menu, and select thechannel. Start the measurement.

Data exchange with the PCThe routes and the current firmware version (update) areloaded from the PC into the VIBSCANNER.
The VIBSCANNER transmits processed routes and files withmultimeter measurement data to the PC.
The definition of the measurement tasks and theevaluation of the measurement data collected is per-formed using the OMNITREND PC software (VIB8.955).
To transmit measurement data Switch the instrument on.
Connect the PC cable provided (VIB 5.430-2) to theinstrument and to the serial PC interface.
Start the data transfer in OMNITREND (see OMNI-TREND Online Help for details).
To update the VIBSCANNER firmware
Do not update the firmware if the battery is empty!(Red LED flashes after the instrument is switched on)
Switch the instrument off.
Connect the battery charger so that the VIBSCANNER issupplied with power during the update.
Start the VIBSCANNER UpdateTool program.(Standard program path: C:/Programs/VibScanner/VSCUpdateTool/VSCUpdateTool.exe)
Follow the instructions that appear on the screen.
