4. Instrument Shutdown
There are three ways of shutting down the instrument, which are the automatic shutdown when
the battery capacity is too low, the automatic shutdown when the set time is up and the manual
shutdown when pressing the power (long press the “Power/Confirm” for about 3 seconds). The
buzzer sounds when shutting down, the LCD shows the “POWER OFF” for about 0.5 seconds
(shown as the following left picture) and then all are off. The instrument is shut successfully
and enters the low power consumption standby mode. If it automatically shuts down because
the power capacity is too low, it will show “Battery Low” first before showing “POWER OFF”,
which is shown as the following right picture.
