Energy Saving - THORLABS PM160T User Manual

5.3 Energy Saving

The PM160(T) features display dimming and an automatic shut down in order to
save battery and the lifetime of the OLED display.
Display Dimming
When a button is pressed, the display brightness is set to 100%. 7 sec after a
button was pressed last time, the display is dimmed to the brightness that can be
adjusted in the menu "Brightness", between a "Min" value and 100%.
Note
The "Min" value is 1 % in local operation mode (Interface:
remote mode (USB or Bluetooth interface enabled and remote connection estab-
lished). This is a convenient feature when using the PM160(T) remotely in a dark
room: The stray light from the OLED display is eliminated.
Auto Shut Down
During battery charging via the USB cable, the auto shut down is disabled, but
after a certain time the display is switched off ("Stand-by").
