CARE AND MAINTENANCE
‣Reflective surfaces such as glass may reflect the beam, causing
two beams to strike the detector at the same time. This may create
inaccurate reference points.
‣This is a precision instrument and should always be transported
within the carry case provided.
‣Always turn the on/off lock to “off” when transporting the unit.
‣Whenever possible, store the instrument in a dry, shady location.
‣The S7BL should be calibrated every 6 months, if ongoing accurate
levelling is required or an impact has occurred.
‣The operator should check the S7BL for accuracy before precision
levelling is attempted.
‣Clean the instrument with a dry, soft cloth after use in dusty, damp
or wet conditions before storing.
‣Smudges and fingerprints may be removed with a damp tissue or
a soft, lint-free cloth.
