Provided it is used in accordance with the Instruction Manual, the
instrument needs no special maintenance. If it should become
soiled in the course of daily use, it may be cleaned with a damp
cloth and a little mild household detergent.
Never use aggressive cleaners, or solvents.
To maintain accuracy, the instrument must be regularly calibrated
by our Service Department. We recommend annual calibration.
