When press the key, the "HOLD" symbol and the last reading of the
meter will be shown on the LCD, the symbol will disappear until
press the key again or turn the function switch, and the readings
comes back. Press "HOLD/BL"key to turn on the meter, the "APO"
symbol disappear, the auto power off function canceled. If turn on the
meter by switch as usual, the auto power off function is on, the meter
will turn off in 15 minutes if without any operation. This key got a
backlight function, press this key for 3 seconds, the backlight on; if
press this key again for more than 3 seconds, the backlight off.
