4. Components Overview

The WIKA TI.80 thermometer consists of the following main components:

• Display: Digital LCD screen showing temperature readings.
• Solar Panel: Integrated black panel below the display, responsible for powering the unit.
• Casing: Round, stainless steel housing protecting internal components.
• Stem: Stainless steel probe extending from the back, containing the thermistor sensor.
• Process Connection: 1/2 inch NPT thread at the base of the stem for mounting.

This image displays the WIKA TI.80 Solar Digital Thermometer. It features a round, stainless steel casing with a digital LCD screen showing a temperature reading of 74.5°F. Below the screen is a black solar panel, and the text 'SOLAR POWERED -50/300°F' is visible. A stem extends from the back of the unit.

5. Installation and Setup

Follow these steps for proper installation:

1. Select Mounting Location: Choose a location that allows the solar panel to receive at least 35 lux of ambient light. Avoid direct sunlight if it could lead to overheating beyond the specified operating limits of the display.
2. Prepare Connection Point: Ensure the process connection point is clean and compatible with a 1/2 inch NPT thread.
3. Install Thermometer: Thread the thermometer's 1/2 inch NPT connection into the prepared port. Use appropriate sealing tape or compound to ensure a leak-free connection. Tighten securely, but do not overtighten to avoid damaging the connection or the thermometer casing.
4. Verify Stem Immersion: Ensure the stem is adequately immersed in the medium to be measured for accurate readings. The thermistor sensor is located at the tip of the stem.
5. Initial Power-Up: Once installed and exposed to sufficient light, the thermometer will power on automatically and begin displaying temperature readings within a few seconds.

6. Operation

The WIKA TI.80 is designed for straightforward operation:

• Reading the Display: The current temperature will be shown on the digital LCD screen. The unit of measurement (°F or °C) will be indicated next to the numerical value.
• Temperature Updates: The display updates approximately every 15 seconds, providing near real-time temperature monitoring.
• Solar Power Indicator: The thermometer operates continuously as long as sufficient light (35 lux or more) is available to the solar cell. No battery replacement is required under normal operating conditions.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your thermometer:

• Cleaning: Wipe the display and solar panel with a soft, damp cloth to remove dust and debris. Do not use abrasive cleaners or solvents, as these can damage the display or casing.
• Solar Cell Care: Ensure the solar panel remains clean and unobstructed to guarantee continuous power supply.
• Inspection: Periodically inspect the thermometer for any signs of physical damage, corrosion, or loose connections. Address any issues promptly.
• Product Care Instructions: The manufacturer recommends wiping clean for general product care.

8. Troubleshooting

If you encounter issues with your WIKA TI.80 thermometer, consider the following:

• No Display:
  • Check if the solar panel is receiving adequate light (at least 35 lux). Move the thermometer to a brighter location if necessary.
  • Ensure the solar panel is clean and free from obstructions.
• Inaccurate Readings:
  • Verify that the stem is fully immersed in the medium being measured.
  • Confirm that the thermometer is operating within its specified temperature range.
  • Ensure the stem is not bent or damaged.
• Intermittent Display: This may indicate insufficient or fluctuating light conditions for the solar cell.

If problems persist after following these steps, contact WIKA customer support for further assistance.
