==CALIBRATION==
*The Pen should be calibrated if the batteries have been changed or if the LCD reads “CAL” followed by
*“- - - -”.
*Remember, calibration involves depressing the Operator Button TWICE and getting ONE
*line (- - - -). To take a reading requires depressing the Operator Button ONCE and getting
*TWO lines (====).
*1. Point the transducer end straight down towards the floor.
*2. Press the Operator Button “distinctly, two times, within 1.5 seconds.”
*3. Initially “CAL” appears on the LCD, followed by “UP” (after about 15 - 30 seconds!)
*4. Invert the transducer end to point straight up toward the sky.
*5. A properly functioning Pen will display “”Good”.
*If “bAd”, repeat the calibration again.
*If this is all unsuccessful, options include
*cleaning the tip (compressed air is recommended)
*change the batteries. Use the little probe that came with the Pen to open the
*battery compartment.
