Low battery indicator
• This message warns the battery voltage is below the minimum recommended and it
needs to be replaced with a new battery.
• If the battery voltage is low, but still allows for the operation of the instrument, the low
battery indicator will turn and stay on until the battery is replaced with a new one.
Note: If the unit turns off immediately after being turned on, it indicates that battery voltage
is below the absolute minimum, and the battery should be replaced to prevent malfunction.
MAX - Maximum reading
• Holds and displays the maximum value of the measurements, with the last digit rounded to ‘0’.
The maximum measurement is automatically reset when turning the unit off or manually by
