NOTE
Menu preferences are not normally retained after the
power is removed from the instrument. To make (a)
menu preference(s) permanent, make the desired
change(s) to settings first and then proceed to the
section Storing the Menu Preferences to make the
changes permanent. Following this procedure will put
the settings into non-volatile memory and allow them
to be restored during instrument power-up.
Setting the Display Intensity
The display intensity (brightness) is adjustable to accommodate
different ambient lighting conditions. It may be set to 25%, 50%,
75%, or 100% of its maximum brightness. To set the display
intensity, proceed as follows:
1. Press the top key next to the display. Rotate the knob until
the top line reads:
>-----SETTINGS-----<
2. Select line 2 (next to the top line) by pressing the second
key. Rotate the knob until line 2 of the display reads
“
Type:Display
“:
-----SETTINGS-----
> Type: Display <
Option: Format
Status: Hex
3. Press the third key to select line 3 of the display (option).
Then rotate the knob until line 3 of the display reads as
follows:
-----SETTINGS-----
Type: Display
> Option: Intensity<
Status: 75%
4.
If line 4 already shows the desired intensity, then no further
action is necessary. Otherwise, select line 4. Then rotate the
knob until line 4 shows the desired intensity. This example
uses “50%”:
-----SETTINGS-----
Type: Display
Option: Intensity
<Update?: 50%
Then press the fourth key (bottom) to update the status.
Pressing any other key cancels the change.
