287/289 Users Manual VAC REL Peak, CF Menu Hz, %, mS dBm dBV REL REL% Close Figure 5. Function Menu est05.eps Menu selection is indicated by the filled-in black square (hereafter the menu selector) to the left of a menu item. Use the four front-panel cursor buttons (5 6 7 8) to position the menu selector next to a menu item. As the menu selector moves between menu items, the four softkeys and their labels change to reflect the available functions and/or modes available for the selection menu item. The example menu in Figure 5 shows the REL (Relative) function as the current selection. The function selected when the menu opens is the function selected the last time the menu was used. To get to the Hz menu item from the REL item, press 6 once, followed by one press of 7. As the menu selector moves between the menu items, the softkey labels change to indicate each softkey's function. Once the desired function or mode appears in one of the softkey labels, press the appropriate softkey to activate it. The pop-up menu closes and the display changes to reflect the selection just made. Pressing the softkey labeled Close closes the pop-up menu, leaving the Meter in the state it was in before pressing the Menu softkey. 14 In most cases, the softkeys revealed by the menu selection act like toggles. The example menu shown in Figure 5 shows REL, REL%, and Close softkeys. In this example, the Meter is not in the relative mode, so pressing the softkey labeled REL would activate, or toggle, the relative mode. If, on the other hand the Meter is already in the relative mode, pressing the same softkey would disable the relative function. In some cases, pressing a function that can not be used with other functions appearing in the menu turns off the previously selected function. For example, in Figure 5, if the Meter is already in the relative function, pressing REL% causes the Meter to turn off relative and display relative percent. In cases where multiple modes have been selected, selecting the first (top-left) menu item always turns off all other functions and modes, and returns the Meter to the primary function selected by the rotary switch. For example, assume that the Meter is setup for frequency (Hz) and is displaying in relative mode as selected through the menu in Figure 5. Moving the menu selector to the menu item labeled VAC and pressing the softkey labeled VAC, clears both frequency and relative selections, leaving the Meter in volts ac only. Menu selections are remembered for each rotary switch position. For example, selecting REL for the volts ac position causes REL to be selected the next time the menu is opened in volts ac, even though in the interim, Hz,%,ms was selected from a similar menu for the millivolts ac function. Up to two columns of four items each are displayed at any one time. If more than eight menu items are available for a primary function, g appears in the lower right-hand corner of the page area of the display, indicating more menu items are available.
