Display
The meter has a 5-digit, vacuum-fluorescent, dual display. This display shows measure-
ment readings, annunciators, and messages. The annunciators indicate measurement units
and the meters operating configuration.
The dual display allows you to see two properties (e.g., volts ac and frequency) of the
input signal you are measuring. Readings are taken and displayed in an alternating
fashion. That is, a reading is taken of one property of the input and sent to a display; then
a reading of the other property is taken and sent to the other display. (For more detail, see
"How the Meter makes Dual Display Measurements" in Chapter 4.)
The display flashes when a measurement exceeds 1000 V dc or 750 V ac, the maximum
rated input level. If an input exceeds the full scale value of the selected range, the
overload annunciator (OL) is displayed.
Primary Display
The primary display (shown in Figure 3-1) consists of the larger digits and annunciators
(see Figure 3-2) and is located on the left side of the front panel. Readings using the rela-
tive (REL), minimum maximum (MN MX), Touch Hold (HOLD), or decibels (dB)
modifiers can be shown on the primary display only.
Secondary Display
The secondary display consists of a set of smaller digits on the right side of the dual dis-
play (see Figure 3-3).
Press S to turn the secondary display on and off. A series of five dashes is shown in
the secondary display when the secondary display has been turned on but a function has
not yet been selected.
