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.
‣ Whenever possible, store the instrument in a dry, shady location.
‣ The HV1R should be calibrated every 6 months, if ongoing
accurate levelling is required or an impact has occurred.
‣ The operator should check the HV1R 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.
