Chapter 5 : MAINTENANCE and

SOFTWARE PACKAGES

As with any device based on solid-state electronics, actual maintenance of the MTEK6000 should be minimal. However, there are certain guidelines that, if followed, will minimize device failure and increase the product’s service life.

Enclosure Maintenance

Enclosure maintenance is a program of routine inspections to insure the integrity of the lid's seal and the various ports in the box's exterior. Excess moisture can ruin an MTEK6000 if allowed to accumulate within the enclosure. Although the circuit boards themselves are conformal coated to protect

against humidity, the wiring interconnections and various exposed metal surfaces are susceptible to corrosion in extreme cases of interior humidity. Here are some checks you should periodically make of the enclosure:

1.Ensure the unit’s mounting arrangement is secure and provides a stable platform for termination of the pressure tubing.

2.Verify the integrity of the enclosure lid

seal. Check the lid gasket for deterioration, chemical damage, tears, or compression.

3.Check for damaged cord grips and missing or damaged RS-232C port caps. Liquid must not be allowed to accumulate within the interior of the enclosure.

4.Examine the RS-232C port. Ensure the port's mounting screws are secure and provide firm support when attaching a serial cable.

Changing the Battery

To replace the battery in the unit:

1.Open the front door by loosening the upper and lower right hand corner screws of the device enclosure and swinging the door out (see Fig 1-1 and 1-2 in Chapter 1).

2.Attach the new battery to connector J-6 or J-7 (see Fig. 2-1 in Chapter 2).

3.Disconnect the old battery from the other connector in the unit.

4.Press any key to wake-up the unit and verify that it is fully operational.

Calibration

Calibration is a crucial element of any scheduled maintenance program. However, because of the unit’s design, software calibration does away with the need for laborious adjustments, simplifying field calibration. See the section on Calibration for more details.
