3. battery symbol A CAUTION Measurements made when the low battery message was displayed could be less accurate If the battery level goes down further the instrument will automatically switch off To continue to use the instrument the batteries must be recharged using the supplied battery charger For instructions on the battery charger please check paragraph 4 7 4 3 Understanding the memory structure of the FiberScanONE The FiberScanONE has memory to store about 2000 measurements To bring structure in the saved data the user can select o PM counter indicator for the paper machine on which the analysis is made Depending on the number of measurements the FiberScanONE can memorize up to 7 machines o Pos counter indicator for the position where the measurement is taken i e after forming table after 1 foilbox etc Per PM up to 31 Positions can be memorized The test result shown for a certain position is the mathematical average of 1 or more measurements on that position o Mea counter indicator for the actual measurement on a certain position Up to 255 Measurements per Position can be stored Example The FiberScan operator starts a dewatering analysis on a paper machine If it is the first machine he measures he will set PM to 1 He checks the machine and sees there are 5 positions where he can take a measurement Pos 1 to 5 At every position he wants to take 3 measurements to check the repeatability of the
4. handle and the control unit are not properly connected Solution is to switch off the instrument and reconnect the two components and carefully tighten the fixating ring F If the FiberScanONE is properly assembled this message can also have another cause which is related to the paper machine When there is strong variation in the test results for example due to turbulence measuring at the dry line or MD mass variations the Speed Accuracy value must be increased Go to Set gt Measure gt Speed Accuracy and set a value higher than 1 usually 2 or 3 is sufficient For more information on the Speed Accuracy setting please refer to paragraph 5 2 4 TIP when this error message appears there are reasons to suspect some kind of pulsations in the machine a further investigation in FFT mode could be useful 4 6 4 Memory error Memory full message The FiberScan can store about 2000 point measurements Of course in continuous or high speed FFT mode the memory will be filled faster When there is no memory left the instrument will stop measuring and give the Memory full message The operator is requested to free memory by downloading data to the PC and or by deleting measurements The Memory error indicates that an irreversible has taken place during writing reading of the memory In that case the memory needs to be reformatted Set gt Extra gt Format memory and all saved data will be lost FELIEST equipme

6. the FiberScan cannot be compared one on one with the results of a gamma gauge because the latter measures the total mass so water fibers and fillers the forming fabric The next paragraph will give more details on how to create a drainage curve The FiberScan is equipped with a temperature sensor in order to compensate for temperature variations The instrument contains a memory card where up to 2000 measurements can be saved The FiberScanONE can be connected to a PC by either the USB cable or wireless through Bluetooth communication 2 2 Evaluation of the test results As mentioned before the FiberScan measures ONLY the water mass and is hardly influenced by fibers fillers and the forming fabric The previously often used gamma gauges measure something a bit different that is the total mass including fibers and forming fabric For that reason the test results of both types of instrument can only be compared with each other after some simple additional calculations The total mass on the forming fabric is expressed by the following formula Mass on fabric FiberScan reading forming fabric water content solids on fabric 10 FELIEST equipment 2 2 1 How to measure the water in the fabrics void volume Due to its measuring principle the FiberScan enables an accurate measurement of the amount of water that is carried by the forming fabric in its void volume With the older gamma gauges one measu
