5. Setup

Your Deli Mechanical Thermo-Hygrometer offers flexible placement options:

• Desktop Placement: The device comes with an integrated stand on its back. Simply unfold the stand to place the thermo-hygrometer on any flat surface such as a desk, shelf, or countertop.
• Wall Mounting: For wall mounting, use the keyhole slot located on the back of the device (refer to Figure 4.3). Secure a screw or nail into your desired wall location, ensuring it is strong enough to hold the device, then hang the thermo-hygrometer onto it.

For accurate readings, place the device in a location that is representative of the general room conditions. Avoid placing it near heat sources (e.g., radiators, direct sunlight), air conditioning vents, or in areas with poor air circulation.

6. Operating Instructions

The Deli Mechanical Thermo-Hygrometer is a passive device that requires no power source. It begins measuring temperature and humidity immediately upon placement.

• Reading Temperature: The larger needle on the outer scale indicates the current temperature in degrees Celsius (°C).
• Reading Humidity: The smaller needle on the inner scale indicates the current relative humidity (%RH).

Allow the device approximately 15-30 minutes to stabilize after initial placement or relocation to ensure accurate readings.

7. Maintenance

• Cleaning: Wipe the device surface and dial with a soft, dry, lint-free cloth. Do not use liquid cleaners, sprays, or abrasive materials, as these can damage the finish or affect the sensors.
• Storage: If storing the device for an extended period, keep it in a cool, dry place away from direct sunlight and extreme temperatures.

8. Troubleshooting

Inaccurate Readings

• Initial Stabilization: If readings appear incorrect immediately after setup, allow the device 15-30 minutes to acclimate to the environment. Mechanical sensors require time to adjust.
• Placement: Ensure the device is not placed near direct heat sources, cold drafts, or in areas with stagnant air, which can skew readings.
• Physical Damage: Inspect the device for any visible damage. If the internal mechanisms are compromised, accuracy may be affected.

No Movement on Dials

• Verify that the temperature and humidity in the environment are within the device's measurable range.
• Ensure the device is not obstructed or jammed.
