The mini-measurement display shows the measurement value of the primary function, if it is not already shown in the page area of the display. For example, when the display is frozen for a HOLD, the mini-measurement display continues to show the input signal (Live) measurement and a mini z. In addition, the minimeasurement display will flash, if z (for inputs above 30 volts) would normally appear in the primary display but is obscured. To warn of the possibility of blowing a current fuse, the minimeasurement display also flashes when current measurements exceed the maximum continuous current levels (see specifications). Page Area The page area of the display is where the main meter content is displayed. The primary display (upper half of the page area) is where the most important value of the selected function is shown. The secondary display contains the bar graph and values that may be measured in addition to the primary function value. For example, with frequency measurement selected in Vac, the frequency value will appear in the primary display with the ac voltage value in the secondary display. Softkey Labels Labels for the four function softkeys (F1 through F4) appear in the bottom row of the display. These labels will change based on the function and/or menu selection. Adjusting Display Contrast When not selecting items on a menu or inputting data, pressing 7 increases display contrast and pressing 8 decreases it.
