1.2.2 Cautions

DO NOT plug the unit into 230V if the heater switches and fuse holder read 115V. This action will cause the fuses to blow and may damage the instrument.

Components and heater lifetime can be shortened by continuous high temperature operation.

DO NOT change the values of the calibration constants from the factory set values. The correct setting of these parameters is important to the safety and proper operation of the calibrator.

DO use a ground fault interrupt device.

Operate the instrument in room temperatures between 5 and 50°C. (41–122° F). Allow sufficient air circulation by leaving at least 6 inches of space between the instrument and nearby objects.

Never introduce any foreign material onto the surface plate. Fluids, etc. can leak into the instrument causing damage.

The instrument is a precision instrument. Although is has been designed for optimum durability and trouble free operation, it must be handled with care. Always carry the unit in an upright position. The instrument should not be operated in excessively wet, oily, dusty, or dirty environments. Do not operate near flammable materials.

If a main supply power fluctuation occurs, immediately turn off the in- strument. Wait until the power has stabilized before re-energizing the in- strument.
