How to use

Power the meter with AAA batteries and turn it on. For incident readings, position the meter’s sensor toward the light source or subject as required and select the ambient mode to record luminance values and recommended exposure settings. For flash metering, set the meter to flash mode and trigger the flash to capture the flash output; the meter will display the appropriate shutter speed, aperture, or ISO combination based on the measurement.

Replace batteries before extended shoots to avoid interruptions and keep the meter’s sensor clean and free from obstructions for accurate readings. When working under mixed lighting, take multiple measurements at key positions to ensure consistent exposure across the scene. Use the compact form factor to carry the meter on location for quick adjustments when lighting conditions change.
