నిర్వహణ

శుభ్రపరచడం:

Wipe the multimeter's casinప్రకటనతో గ్రాamp cloth. Do not use abrasive cleaners or solvents. Ensure the device is off and disconnected from any circuits before cleaning.

నిల్వ:

When not in use for extended periods, remove the batteries to prevent leakage. Store the multimeter in its durable carrying case in a cool, dry place away from direct sunlight and extreme temperatures.

ట్రబుల్షూటింగ్

• డిస్ప్లే/పవర్ లేదు:
  • బ్యాటరీ ఇన్‌స్టాలేషన్‌ను తనిఖీ చేయండి మరియు బ్యాటరీలు ఖాళీ కాలేదని నిర్ధారించుకోండి. అవసరమైతే భర్తీ చేయండి.
  • Ensure the rotary dial is set to an active function, not "OFF".
• సరికాని రీడింగ్‌లు:
  • Verify test leads are correctly inserted into the appropriate input jacks for the selected function.
  • Ensure good contact between test probes and the circuit/component.
  • Check if the batteries are low (indicated by the low battery icon on the display). Low batteries can affect accuracy.
• Display shows "OL" (Overload):
  • The measured value exceeds the selected range. For auto-ranging meters, this usually means the value is beyond the meter's maximum capability for that function.
  • Ensure you are not attempting to measure current in a voltage input, or vice-versa, which can damage the meter.
