Safety Information

1 Before You Start

cautions. Before working inside the equipment, turn the power off and disconnect the power cord.

•Always replace the fuse with one of the same rating, voltage, and type.

•This instrument is intended for indoor use only.

•Overhead clearance is required. DO NOT place this instrument under a cabinet or other structure.

•DO NOT use this unit for any application other than calibration work.

•DO NOT use this unit in environments other than those listed in the user’s guide.

•DO NOT operate near flammable materials.

•Use of this instrument at HIGH TEMPERATURES for extended periods of time requires caution.

•Completely unattended high temperature operation is not recommended for safety reasons.

•If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

•Before initial use, or after transport, or after storage in humid or semi-hu- mid environments, or anytime the instrument has not been energized for more than 10 days, the instrument needs to be energized for a "dry-out" period of 2 hours before it can be assumed to meet all of the safety re- quirements of the IEC 1010-1. If the product is wet or has been in a wet environment, take necessary measures to remove moisture prior to apply- ing power such as storage in a low humidity temperature chamber operating at 50°C for 4 hours or more.

•The instrument generates extreme temperatures. Precautions must be taken to prevent personal injury or damage to objects. Sensors may be ex- tremely hot when removed from the instrument. Cautiously handle sen- sors to prevent personal injury. Carefully place sensors on a heat resistant surface or rack until they are at room temperature. Allow the surface to cool before transporting the instrument.

•Use only a grounded AC mains supply of the appropriate voltage to power the instrument. Refer to Section 3.1, Specifications for power de- tails.

•The instrument is equipped with operator accessible system fuses. If a fuse blows, it may be due to a power surge or failure of a component. Re- place the fuse once. If the fuse blows a second time, it is likely caused by failure of a component part. If this occurs, contact an Authorized Hart Scientific Service Center (see Section 1.3). Always replace the fuse with one of the same rating, voltage, and type. Never replace the fuse with one of a higher current rating.

•Follow all safety guidelines listed in the user’s manual.

•Calibration Equipment should only be used by Trained Personnel.
