True-rms Digital Multimeters

Features

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 mini-

measurement 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 mini-

measurement 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.
