A. Preventive Maintenance of laboratories

Preventive maintenance is carried out periodically to minimize breakdowns and maintain laboratory equipment in proper working condition.

  1. Inspect all laboratory equipment, instruments, power supplies, and connections regularly for faults or damage.
  2. Clean electronic equipment, trainer kits, computers, and workstations regularly to prevent dust accumulation.
  3. Check power cables, plugs, sockets, switches, MCBs, fuses, and earthing connections for electrical safety.
  4. Calibrate measuring instruments such as CRO/DSO, Multimeters, function generators, and frequency counters periodically.
  5. Check the proper functioning of microprocessor, microcontroller, communication, and electronic trainer kits.
  6. Inspect patch cords, BNC cables, probes, connectors, and other accessories, and replace damaged items.
  7. Maintain proper ventilation, lighting, temperature, cleanliness, fire safety, and emergency arrangements in the laboratory.
  8. Maintain updated records of equipment inventory, calibration, preventive maintenance, breakdowns, repairs, and servicing.

B. Corrective Maintenance of Laboratories

Corrective maintenance is undertaken whenever a fault, malfunction, or breakdown is reported. Necessary repair or replacement is carried out to restore the equipment to satisfactory working condition.

  1. Identify and diagnose faults in laboratory equipment, instruments, circuits, and power supplies.
  2. Repair or replace damaged components such as ICs, transistors, resistors, capacitors, cables, connectors, and switches.
  3. Troubleshoot malfunctioning electronic trainer kits, oscilloscopes, function generators, power supplies, and measuring instruments.
  4. Repair faulty wiring, loose connections, patch cords, switches, sockets, and other electrical connections.
  5. Replace damaged or non-functional computer systems, peripherals, communication devices, and networking components.
  6. Calibrate or service measuring instruments whenever inaccurate readings or abnormal performance is observed.
  7. Record all faults, repairs, replaced components, and maintenance activities in the laboratory maintenance register.
