Operation
The BK Precision 615 CE Digital Lightmeter is designed for simple, one-hand operation to measure light in lux and foot-candle units. To operate the lightmeter, follow these basic steps:
1. Set the function switch to the desired lux or foot-candle units.
2. Remove the sensor head cover.
3. Hold the sensor head steady and ensure the light source completely fills the cosine correction dome.
4. Move away from the sensor head to avoid shadowing it.
5. Read the illuminance value from the display. If the magnitude is unknown, set the range switch to the highest range and reduce until a satisfactory reading is obtained.
6. Cover the sensor head after use to extend sensor life.
The lightmeter features a backlit LCD display, PEAK-HOLD, and DATA-HOLD functions. The PEAK-HOLD mode is activated by pressing the “PEAK” button, and the DATA-HOLD mode is activated by pressing the “HOLD” button.

Safety & Warnings
To avoid electric shock, do not operate this product in wet or damp conditions. To avoid injury or fire hazard, do not operate this product in an explosive atmosphere. To avoid eye injury, wear eye protection if there is a possibility of exposure to high-intensity rays. Do not immerse in liquids, clean the sensor head using only a damp cloth. Cover sensor head when not in use to extend silicon photodiode sensor life. Keep the plastic domed cosine corrector clean and free of scratches. It may be cleaned with a soft cloth and isopropyl alcohol. When light is received from many directions simultaneously, take special care to avoid reflections or shadowing the sensor with your body. For best accuracy, repeat the measurement several times to ensure that the light source has remained stable. Avoid flexing the cable excessively at either end of the cable.
