OPERATING PROCEDURESOn-Line ProceduresThese are the procedures that you perform during a measurement.Inspecting The 9. Inspect the Meter display for a few cycles and verify that all dipolesM eter Displayhave a stable signal. It is unlikely that good data can be obtained iflarge SP drift is present or by the presence of noise. Large SP drift isindicated by the shifting of the bars sideways while the presence ofnoise is indicated by random shifts.10. If the bars drift off scale, push Z (zoom) to re-scale the display.11. Observe the analog meter if there seems to be any problem as itprovides you with more information.Changing The 12. Press an appropriate Number key (1-8) to switch the analog meter toAnalog Meter Toany valid dipole.Another DipoleObserving The 13. Press GRAPH. The bar graph of the dipole with the highest dipoleB ar Graphnumber appears. If the graph is too small or is over-flowing the top,press Z (zoom) to re-scale.14. Press an appropriate Number key (1-8) to view the Graph of thedesired dipole.15. Press NUMBER. The Numeric display appears.Inspecting The 16.Inspect and monitor the data while the reading progresses. CloselyData Numerically m onitor the Mx and S.D. of the dipoles with the weakest signal (Vp)to ensure good quality data.17. Wait until the reading is automatically terminated (number of selectedc ycles) or manually terminate the measurement by pressing STOP.Note: Error messages may appear along the bottom of the displayaccompanied by a Beep. See the Troubleshooting section.Note: Instruments with software Version l.3 and later allow the currentto be entered while a measurement is in progress as follows: pressCHANGE and enter the current after the prompt at the bottom lefthand cornerof the display. When finished, press ENTER. Theinstrument response to keystrokes is somewhat slow as themicroprocessor is carrying out other tasks at the same time.5-3
