(factory & user) for all ranges.
Factory Cal - The recorder is calibrated in the factory. These are pre-stored calibration val-
ues that cannot be changed by the user. If the recorder is re-calibrated to a User Cal the
factory values can be restored at any time.
User Cal - User calibration can be applied at any time. To meet the accuracy values spec-
ified (see

On initial power up the Factory Cal and the User Cal are the same.
