Other system-related operations
Each system-related operation performs a task that is not measurement-related but plays an
important role in making your measurements.
Display
Definition
The Model 2100 Digital Multimeter has a 5x7 dot-matrix, dual display with three-color (white, red
and yellow) annunciators for better viewing. A maximum of 13 characters are allowed for upper
row dot-matrix display, and a maximum 16 characters are allowed for lower row dot-matrix display
(refer to
Figure 4-27).

The Model 2100 dot-matrix display screen
You also have the option to turn off measurement readings on the instrument display for faster
measurements. When "OFF" is lit at the lower right corner of the display screen, measurement
readings will not be sent to the instrument display, but can be viewed later from a remote interface
(note that this does not mean the display is turned-off). This option accelerates the measurement
process because there is no I/O delay. Turning-off the measurement readings on the instrument
display will not affect the messages displayed from the Recall, Menu, and Config operations.
NOTE Messages sent from a remote interface (for instance, your PC terminal) will replace the
messages on the lower row of the original instrument display.
Default
The instrument display default is "ON." If you change the "ON/OFF" setting (which is stored in
volatile memory), the default setting will be restored when the meter is shut-off.
Controlling the Model 2100 display
You can control the instrument display through the front panel or using a remote interface.
NOTE Messages sent from a remote interface will have priority over messages sent from the
front panel.
To control the instrument display from the front panel:
1. Press the MENU key.
2. Use the PREV and NEXT keys to select the SYSTEM submenu and press ENTER.
