Dual Display
The Meter has a 5-1/2 digit vacuum fluorescent dual display. See Figure 3-2 and Table 3-
2 for an overview of the display annunciators and indicators
The dual display is comprised of a primary display and a secondary display, which show
measurement readings, annunciators and messages. The annunciators indicate
measurement units and the Meter’s operating configuration.
The dual display allows you to see two properties for the input signal you are measuring.
The Meter alternates between properties, measuring the first property and showing it on
one display, and then measuring the second property and showing it on the other display.
(For more detail, see the “How the Meter Takes Dual Display Measurements” section in
Appendix A.)
If an input exceeds the full-scale value of the selected range, the Meter displays 0Lto
indicate an overload.
Primary Display
The primary display comprises the lower segment of the dual display, and consists of the
larger digits and annunciators. The primary display shows measurements taken using the
relative readings (REL), minimum maximum (MIN MAX), Touch Hold (HOLD), and
decibels (dB) function modifiers.
Secondary Display
The secondary display comprises the upper segment of the dual display, and consists of
the smaller digits and annunciators.
Function modifiers REL, HOLD, MIN MAX, and dB and the manual range mode cannot
be selected for the secondary display. The secondary display is either in autorange, or the
same range as the primary display if both displays are in the same function.
