KEYPAD AND DISPLAY DESCRIPTIONS12¯¯¯¯¯¯3 ¯¯¯4 ¯ ¯ ¯5 ¯ ¯ ¯6¯ ¯ ¯78¯ ¯ ¯¯ ¯ ¯DUR dddBAT1: bbbNotes:This is a simulation of up to eight edgewise meters. The bars represent theneedles where they would normally rest during the different phases of the IPsignal. The left hand position indicates the -Vp, the centre position represents -/+Mx and the right hand position is +Vp. The data is updated once a cycle, andindicates non-averaged data.The Vp deflection is set to 75% of Full Scale from the Vp obtained during thefirst cycle and SP is initially bucked out. On-going changes in amplitudes or SPdrift are made with reference to those values.If considerable changes take place during a measurement, it is possible to re-zeroand re-scale the display (zoom in) with the “z” key.GraphDisplayDUR - This is the number of cycles averaged of the dipole with the mostrejections which could be due to internal saturation, or with low signal. Otherdipoles may have more cycles. If there were no rejections this represents thenumber of cycles for all the dipoles. This parameter appears on all On-Linedisplays.The graph display shows you the decay in a graphical format. This display isaccessible via the GRAPH key followed by a numeric key(1-8) while a measurement is in progress or before recording the data.3-17
