A straightforward guide to the UVB-1 Series controls, display and charging routine.

Open the product manual

Use these steps with the UVB-1 Series product manual.

Before you begin

Remove the battery insulating tab before first use. The curved groove on the back identifies the battery cover.

The meter uses a rechargeable LIR2450 cell. The guide states that children under 12 shall not use the product.

Switch the meter on

Short press the ON/OFF button on the right side of the meter. The display shows the live UVI value along with battery percentage and voltage.

Aim the sensor

Point the sensor on the left directly at the light source. Read the UVI value on the display.

Hold the current value

While measuring, short press the ON/OFF button. The current value is locked so you can view or record it away from the source.

Press the button again to release HOLD and return to live readings.

Switch the meter off

Long press the ON/OFF button to switch the meter off. It also turns off automatically after two minutes of inactivity.

Charge the battery

Follow the illustrated battery and charger instructions in the manual. The included RSC-X2-3 charger is for the rechargeable cell; align the positive battery pole with the charger's positive mark.

  • Red indicator: charging.
  • Green indicator: fully charged.
  • Charging time stated in the guide: three to four hours.

Read the right specification

The guide lists a sensor wavelength range of 240 to 320 nm. This is separate from the UVI value shown on the screen. Read the UVB and UVI guide for a short explanation.
