OLED Auto Dim function
Your multimeter’s OLED automatically dims if the rotary
switch is not moved or a key is not pressed for 90 seconds
(default). This auto dim behavior is enabled by default.
Pressing any key or changing the rotary switch position will
cancel this effect and reset the auto dim timer.
To disable the auto dim, refer to “Changing the OLED
behavior” on page 121.
Increase the OLED brightness
If viewing the display becomes difficult in low- light
conditions, press to change the OLED brightness.
The LOW, MEDIUM, or HIGH setting must be selected in the
multimeter’s setup (browse to Menu 3 > BACKLIT) prior to this
action.
Pressing repeatedly will increase the OLED brightness
from low to medium to high (and back to low again).
You are advised to select an suitable brightness level based
on your needs to conserve battery life if you wish to control
the OLED brightness level manually.
NOTE
The auto dim function is enabled by default. Refer to “Changing the OLED
behavior” on page 121 to disable the auto dim function before you can
manually change the OLED brightness.
