പ്രവർത്തന നിർദ്ദേശങ്ങൾ
പവർ ഓൺ/ഓഫ്
Press the power button (usually marked with a power symbol) to turn the device on. Press and hold the power button to turn it off. The meter features an automatic shutdown function to conserve battery life, which can also be disabled if needed.
അളവുകൾ എടുക്കൽ
Once powered on, the meter will immediately begin displaying current temperature and humidity readings. Allow a few seconds for the readings to stabilize, especially when moving the meter to a new environment.
മോഡ് ബട്ടൺ
Use the "MODE" button to cycle through different display modes, such as ambient temperature, dew-point temperature, and wet bulb temperature. Refer to the on-screen indicators to identify the current mode.
പരമാവധി/മിനിറ്റ് പ്രവർത്തനം
Press the "MAX/MIN" button to view the maximum and minimum recorded temperature and humidity values since the device was last reset or powered on. Press again to cycle through MAX, MIN, and current readings.
ഡാറ്റ ഹോൾഡ് പ്രവർത്തനം
To freeze the current readings on the display, press the "HOLD" button. This is useful for recording values without needing to write them down immediately. Press the "HOLD" button again to release the data hold and resume live readings.
Temperature Unit Conversion (°C/°F)
The meter supports both Celsius (°C) and Fahrenheit (°F) temperature units. Consult the manual or device interface for specific instructions on how to switch between these units, typically via a dedicated button or a combination of button presses.

വൃത്തിയാക്കൽ
To clean the meter, wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or display. Keep the sensor area clean and free from dust or debris for accurate readings.
സംഭരണം
When not in use for extended periods, remove the battery to prevent leakage and store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
ബാറ്ററി മാറ്റിസ്ഥാപിക്കൽ
Replace the 9-volt battery when the low battery indicator appears on the display. Follow the battery installation steps outlined in the "Setup" section.
ട്രബിൾഷൂട്ടിംഗ്
- ഒരു ഡിസ്പ്ലേയും/ഉപകരണവും ഓണാക്കുന്നില്ല:
Check if the battery is correctly installed and fully charged. Replace the battery if necessary.
- കൃത്യമല്ലാത്ത വായനകൾ:
Ensure the sensor is clean and unobstructed. Allow sufficient time for the meter to stabilize in the environment. Avoid placing the meter near heat sources, direct sunlight, or strong air currents that could affect readings.
- Display Flickering or Unresponsive:
This could indicate a low battery. Replace the battery. If the issue persists, try resetting the device by removing and reinserting the battery.
