Ključne karakteristike:

• Large backlit LCD display with 40-segment bar graph for clear readings.
• Wide measurement range up to 40,000 Fc (Foot-candles) or 400,000 Lux.
• Cosine and color corrected measurements for high accuracy.
• Precision silicon photo diode and spectral response filter for reliable data.
• Peak mode (10mS) to capture the highest reading.
• Relative mode to indicate changes in light levels.

Upute za rad

Uključivanje/isključivanje

• Pritisnite tipku VLAST gumb za uključivanje ili isključivanje mjerača.
• The meter features an Auto Power Off (APO) function to conserve battery life.

Uzimanje mjerenja

1. Ensure the light sensor is positioned in the area where light intensity is to be measured. The sensor should be facing the light source.
2. The current light reading will be displayed on the large backlit LCD.

Funkcijski gumbi

• JEDINICE: Press to toggle between Foot-candles (Fc) and Lux units.
• RASPON: Press to manually select the measurement range. The meter also has an auto-ranging feature.
• MAKS./MIN: Press to display the maximum or minimum light reading recorded since the meter was powered on or the function was reset.
• VRH: Activates Peak mode, capturing the highest reading over a 10mS period. Useful for measuring short light flashes.
• REL (Relative): Activates Relative mode. This sets the current reading as a reference point (zero), and subsequent readings show the deviation from this reference.
• DRŽI: Freezes the current reading on the display. Press again to release.
• POZADINSKO SVJETLO: Press the light bulb icon button to turn the display backlight on or off for improved visibility in low-light conditions.

Održavanje

Čišćenje

• Wipe the meter and sensor with a dry, clean, soft cloth.
