7. Press CONT (F4) to calibrate.

Press ABRT (F3) to quit without changing calibration.

8. Wide Millivolt calibration is completed.

Disconnect test equipment, reconnect wires, and install enclosure cap.

This completes the calibration checks and procedures

6.2 PREVENTIVE MAINTENANCE

Preventive maintenance consists of periodic inspection of the transmitter, cleaning the external surface of

the transmitter's enclosure, and draining condensate from conduit. Preventive maintenance should be

performed at regularly scheduled intervals.

NOTE

The electronics module contains integrated circuits that can be damaged by

improper handling. The high quality devices used contain built-in protective

circuitry, however, they can be damaged by low energy, high voltage

electrostatic discharge. Follow procedures to prevent the buildup and

discharge of electrostatic energy (see Service Kit below).

6.2.1 Tool and Equipment Requirements

The following tools and equipment are required for servicing:

Ÿ Set of Phillips, flat-blade, and Torx-Head screwdrivers.

Ÿ Service Kit containing wrist strap and conductive mat (P/N 15545-110 or equivalent) for handling

semiconductor components and circuit board assemblies.

Ÿ Digital Multimeter (DMM); see Section 6.1.1 for specifications
