The meter backlight goes dim after 30 seconds of no activity and goes into sleep mode after
60 seconds of no activity. These actions do not occur if the meter is in real-time mode or while the
meter is measuring. After 30 minutes in sleep mode, the meter power goes off.
To cancel the sleep mode, push any key. The display brightness goes back to the normal level and
all keys go back to their normal functions.
