Environmental Condition ,handling the probes and handling the base and the

calibration standards

• Instrument and accessories are designed for use at temperature between 5 and 45 ‘ c (41 … 113’f) .the equipment may be stored at temperature between 5 and 60 ‘C.

• Make sure to avoid direct contact of acid or acid solution with the instrument or the accessories.

• Place the probes rapidly, but gently on the surface of the measuring

• Do not drag the probe over the surface of the measuring object

• do not dirt or scratch the calibration standards! Corroded, dirtied or scratched calibration standards or standards with deep gouges have to be replaced by new standards

• To protect the calibration standards from dirt or damage ,keep and store the standards in the supplied calibration case.
