number displayed must match the number listed on the calibration reference. If the

2. Remove the white calibration reference from the docking station and position the
instrument on the reference as previously discussed. Hold the instrument down and
momentarily press one of the Read buttons. Hold steady until the instrument indicates
that both the white calibration readings are complete.

on the docking station. The display indicates that the Black Ref measurements are now
required. Hold the instrument steady against the docking station and momentarily press
one of the Read buttons to take the measurements. You must keep the instrument steady
