♦ An internally mounted beeper, which emits a short tone in
response to a valid keystroke on the keypad. The beeper
sounds a longer tone if you press an invalid key, if the gauge
displays an error message, or to signal the conclusion of a
measurement.
♦ A USB port that can be used to output data to a USB printer
or storage device (flash drive or external hard drive).
♦ A serial port used to connect the gauge to a computer or
printer for data transfer and printing.
♦ Calibration offsets (density and trench) to expand
measurement possibilities, and to enhance gauge readings
on materials that may fall outside the range of factory
calibration.
