6. Operating Instructions
6.1 Kutora Chiyero
- Ensure batteries are installed and the meter is powered ON.
- Remove the protective cap from the UV sensor.
- Zeroing the Meter: In an area with no UV light (e.g., in a dark room or with the sensor completely covered), press the ZERO button. The display should show "0" or a value very close to zero. This step ensures accuracy.
- Position the UV sensor towards the UV source or area you wish to measure.
- Read the UV radiation value displayed on the LCD screen. The measurement updates approximately every 3 seconds.
6.2 Kuchinja Measurement Units
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Press the UNIT button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
