Maintenance

Perform the following maintenance procedures to ensure the Data Record System operates correctly. Refer to Repair if you identify an issue or broken equipment during maintenance.

Notice Ensure that the maintenance procedures in this section are performed only by qualified personnel.
Notice Use ESD prevention measures when performing maintenance procedures.

Cleaning

Cleaning procedures consist of exterior and interior cleaning of the chassis. Refer to your instrument user documentation for information about cleaning the individual instruments in your system.

Caution Always disconnect the Data Record System DC power cable before cleaning or servicing the chassis.
Attention Déconnectez toujours le câble d'alimentation CC du Data Record System avant de nettoyer le châssis ou d'en effectuer la maintenance.

Cleaning Interval

Clean dust from the chassis exterior (and interior) as needed, based on the operating environment. Periodic cleaning increases reliability.

Cleaning the Chassis Exterior

Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild soap solution. Remove any soap residue by wiping with a cloth moistened with clear water. Do not use abrasive compounds on any part of the chassis.

Notice Use the following guidelines to avoid damaging the Data Record System when cleaning the chassis exterior:
  • Avoid getting moisture inside the system during exterior cleaning, especially through the top vents. Use only enough moisture to dampen the cloth.
  • Do not wash the front- or rear-panel connectors or switches. Cover these components when cleaning the chassis.
  • Do not use harsh chemical cleaning agents; they may damage the Data Record System. Avoid chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.

Cleaning the Chassis Interior

Use a dry, low-velocity stream of air to clean the interior of the chassis. Use a soft-bristle brush for cleaning around components.

Calibration

NI provides calibration services for instruments in the Data Record System that require calibration. NI recommends that you adhere to the calibration interval for all supported instruments in your system. For the latest information about available calibration service levels for your instrument, refer to ni.com/r/nical.

Table 7. Instrument Calibration Intervals
Instrument Function Recommended Calibration Interval
PXIe-1092DC Chassis 1 year
PXIe-1095DC Chassis 1 year
PXIe-6683H Timing and Synchronization 1 year

Factors such as shelf life and storage temperature can affect an instrument's recommended calibration interval. Refer to the specifications for your instrument to calculate the appropriate calibration interval.
