1. Inleiding
The TENMARS TM-213 is a compact, professional UVAB light meter designed for accurate measurement of ultraviolet radiation. This device is suitable for a variety of applications, including industrial monitoring, UV sterilization, graphic arts, photochemical matching, UV EPROM erasure, photoresist exposure, and curing of inks, adhesives, and coatings. It is also useful for laboratory studies such as weathering degradation, virology, microbial genetics, DNA research, and biological hoods.
This manual provides detailed instructions for the safe and effective use of your TM-213 UVAB Light Meter. Please read it thoroughly before operation and retain it for future reference.
2. Veiligheidsinligting
To ensure safe operation and to prevent damage to the meter, please observe the following safety precautions:
- Moenie die meter gebruik as dit beskadig lyk of as die casing is oop.
- Avoid exposing the meter to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Do not attempt to repair or modify the meter. Refer all servicing to qualified personnel.
- Remove batteries if the meter is not to be used for an extended period to prevent battery leakage.
- Hou die sensor skoon en vry van obstruksies vir akkurate lesings.
- This device measures UV radiation. Prolonged exposure to high levels of UV radiation can be harmful. Use appropriate personal protective equipment when working in environments with high UV levels.

5. Opstelling
5.1 Battery installasie
The TM-213 requires two 1.5V AAA batteries for operation. Batteries are not included with the device.
- Vind die batteryklepdeksel aan die agterkant van die meter.
- Use a small screwdriver to loosen the screw securing the battery cover.
- Verwyder die batterydeksel.
- Plaas twee 1.5V AAA-batterye in en let op die korrekte polariteit (+/-) soos aangedui in die kompartement.
- Plaas die batterydeksel terug en draai die skroef stewig vas.

5.2 Aan-/afskakel
- To turn the meter ON, press the green Power button (●).
- To turn the meter OFF, press the green Power button (●) weer.
- The meter features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.
6. Bedryfsinstruksies
6.1 Neem 'n meting
- Ensure batteries are installed and the meter is powered ON.
- Remove the protective cap from the UV sensor.
- Nulstelling van die meter: In an area with no UV light (e.g., in a dark room or with the sensor completely covered), press the NUL 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 Verandering van meeteenhede
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Druk die EENHEID button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
6.3 Data Vashou Funksie
Om die huidige lesing op die skerm te vries:
- Druk die HOU button during a measurement. The reading will be frozen.
- Druk die HOU button again to release the reading and resume live measurement.
7. Onderhoud
7.1 Skoonmaak
- Vee die meter se c afasing met 'n sagte, damp lap. Moenie skuur skoonmaakmiddels of oplosmiddels gebruik nie.
- Keep the UV sensor clean and free of dust or debris. Use a soft, lint-free cloth to gently clean the sensor surface.
7.2 Berging
- When not in use, always place the protective cap over the UV sensor.
- Store the meter in its carrying case to protect it from dust, moisture, and physical damage.
- Indien dit vir 'n lang tydperk gestoor word, verwyder die batterye om lekkasie te voorkom.
- Berg in 'n koel, droë plek weg van direkte sonlig en uiterste temperature.

8. Probleemoplossing
If you encounter issues with your TM-213 meter, refer to the table below for common problems and solutions.
| Probleem | Moontlike oorsaak | Oplossing |
|---|---|---|
| Meter skakel nie aan nie. | Dooie of verkeerd geïnstalleerde batterye. | Check battery polarity. Replace with fresh 1.5V AAA batteries. |
| Display shows "OL". | Overload condition; UV radiation exceeds the meter's range. | Move the meter further from the UV source or use in a lower intensity environment. |
| Onakkurate of wisselende lesings. | Dirty sensor, improper zeroing, or external interference. | Clean the UV sensor. Perform a zero calibration in a dark environment. Ensure no strong electromagnetic fields are nearby. |
| Meter shuts off unexpectedly. | Automatic shutdown activated or low battery. | This is normal after 15 minutes of inactivity. If it happens during use, replace batteries. |
