VABIRA VBR-200 PAR Meter User Manual

1. Einleitung

The VABIRA VBR-200 is a versatile PAR (Photosynthetically Active Radiation) meter designed for accurate measurement of light intensity in various growing environments. It provides essential data such as PPFD (Photosynthetic Photon Flux Density), DLI (Daily Light Integral), LUX, CCT (Correlated Color Temperature), temperature, humidity, and VPD (Vapor Pressure Deficit). The device also features data logging capabilities and can function as a light dimmer.

4.1 Basic Measurements (PPFD, DLI, Temp, Hum, VPD)

The VBR-200 can display real-time measurements directly on its screen.

Figure 5: The VBR-200 displaying Temperature, Humidity, and VPD measurements, crucial for environmental control.

• PPFD Measurement: Position the PAR & Light Sensor at the desired measurement point. The device will display the PPFD value in µmol/(m²·s). The VBR-200 accurately measures PAR according to the McCree Curve.
• DLI Recording: The device automatically records Daily Light Integral (DLI) every second. DLI is displayed in mol/(m²·d).
• Temperature, Humidity, and VPD: Ensure the Temperature & Humidity Sensor is properly connected and positioned in the environment to be measured. The screen will show real-time temperature, relative humidity (%RH), and Vapor Pressure Deficit (VPD) in kPa.

4.2 CCT Measurement

The VBR-200 can also test the Correlated Color Temperature (CCT) of light sources.

Figure 6: The VBR-200 is capable of measuring Correlated Color Temperature (CCT), ranging from warm to cool light.

4.3 Data Logging and Analysis

Connect the VBR-200 to a Windows computer using the data cable to access the "Data Monitor" software. This software allows you to:

• View Echtzeitdaten.
• Review historical data for DLI, PPFD, and VPD, specific to every minute.
• Analyze change curves over time (e.g., daily, monthly DLI).

4.4 Dimmerfunktion

The VBR-200 can be used to control the power of compatible grow lights, acting as a dimmer. This function supports most brands but may not be compatible with all specific models (e.g., Spixxx Farmxx, Maxx Hydxx, Bloox Plxx, Migxx).

Figure 7: The VBR-200 can function as a light dimmer, adjusting light power based on a set percentage or to achieve a target PPFD.

There are two primary ways to use the dimmer function:

1. Prozenttage-based Dimming: Adjust the light power to a desired percentage.
2. PPFD Target Dimming: The meter will automatically adjust the light's power to achieve a required PPFD value.

5. Spezifikationen

Figure 8: Detailed specifications for the VBR-200 PAR Meter.

The VBR-200 utilizes a PAR Sensor IC with a spectral response close to PAR curves (400-700 nm), optimized for plant photosynthesis. This differs from LUX sensors, which are calibrated for human eye sensitivity and are less suitable for measuring light for plant growth.

6. Wartung

• Reinigung: Use a soft, dry cloth to clean the meter and sensors. Do not use abrasive cleaners or solvents.
• Lagerung: Bewahren Sie das Gerät bei Nichtgebrauch an einem kühlen, trockenen Ort fern von direkter Sonneneinstrahlung und extremen Temperaturen auf.
• Batteriewechsel: Tauschen Sie die Batterien aus, sobald die Anzeige für niedrigen Batteriestand auf dem Bildschirm erscheint, um genaue Messwerte zu gewährleisten.
• Sensorpflege: Handle sensors with care. Avoid dropping or subjecting them to strong impacts. While the PAR sensor is designed to be durable, including some water resistance, it is not intended for prolonged submersion unless specified for specific models (e.g., VBR-AQUA for aquariums).
