3GENERAL INFORMATION

SpectraPen mini is a small, portable and affordable calibrated spectroradiometer and quantum light meter, which is

controlled via mobile application called SpectraPen accessible on Google Play. The communication with the mobile phone

is provided by Bluetooth Low Energy module.

The SpectraPen mini measures Irradiance spectrum and light intensity in three units –Irradiance, Photon flux density and

Illuminance. The device is calibrated for visible light in the range from 340 to 850 nm.

The SpectraPen mini serves for real-time measurement of light quality and intensity. It is ideal as a multi-purpose

instrument for research, industrial and agricultural applications.

Parameters measured by the SpectraPen mini:

Spectrometer - quantitative light intensity at different wavelengths

•Irradiance spectrum [µW.cm-2.nm-1]

Light Meter - absolute light intensity at defined range of wavelengths of the electromagnetic spectrum

•Irradiance [W.m-2] in user defined range of the electromagnetic spectrum

•Photon flux density [µmol.m-2.s-1] in user defined range of the electromagnetic spectrum

•Illuminance [Lux] - total luminous flux incident on a surface, per unit area

3.1 DEVICE DESCRIPTION

Sensor with cosine corrector

The optical part of the SpectraPen mini, cosine corrector, is placed in the middle of the white side of the device and is

protected by sealing against dirt and moisture.

Integration time of the internal detector is set automatically according to the ambient light intensity.

The sensor part should be always dust and dirt free and maintained carefully as any scratches on the

surface might interfere with the correct results of the measurement.

Connector for charging

USB connector is used for charging of the SpectraPen mini device using PC, USB wall adapter, USB power bank etc.

Power button

Power button is the main Switch ON/OFF button.

Magnetic holder

The magnetic holder is placed under the green cover and serves for attaching of the device to metal surface.

5CARE AND MAINTENANCE

•Never submerge the device in water!

•The device should not come in contact with any organic solvents, strong acids or bases.

•Keep the optical part clean and dry. If cleaning is needed, use soft, non-abrasive tissue.

It is recommended to re-calibrate the device by the manufacturer every 2 years.

6GETTING STARTED

1. Download and install the application to your smartphone or tablet. The SpectraPen application is free available on

Google Play or can be also downloaded from product websites available via the QR code placed on the bottom of the

device.

The application is compatible with Android version 5.0 and higher.

2. Before you start operating the device, please connect the SpectraPen mini to USB charger to charge the battery.

3. To initialize the SpectraPen mini, please press the power button for about 10 seconds until the green indication light

indicates initial state. The device can be switched on/off by short press the power button followed by green (power

on) or red (power off) light flash.

4. While the SpectraPen mini is on, the state is indicated by light flashing. The device turns off automatically after 2

minutes or any time after pressing the power button.

5. Open the SpectraPen application and navigate in the side bar menu to Connections. The application automatically

searches the available SpectraPen mini devices; then select the required one. Last two numbers in the name of

searched devices correspond to the last two numbers of serial number placed on the bottom of the device. Once the

SpectraPen mini device is paired with the application the Bluetooth mark in the right corner of the application window

changes to green .

Fig. 2 Pairing of the SpectraPen mini with the mobile application.

Last two numbers in the name of SpectraPen mini device visible in the application corresponds to

serial number written on the bottom green side of the device.

6. From the side bar menu select the Dark calibration (Fig. 4). Before you start calibration process please make sure that

the sensor is completely covered. Please note that covering by finger is insufficient for the infrared part of the
