Pukapuka Kaiwhakamahi mō te Mita Mārama Extech HD400

Kupu Whakataki

The Extech HD400 is a robust light meter designed for accurate measurement of light intensity across a wide range. It utilizes a precision silicon photo diode and a spectral response filter to ensure cosine and color corrected measurements. This manual provides essential information for the proper setup, operation, and maintenance of your HD400 Light Meter.

Āhuatanga matua:

• 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.

Nga Tohutohu Whakahaere

Te Hia/Weto

• Pehia te MANA button to turn the meter on or off.
• The meter features an Auto Power Off (APO) function to conserve battery life.

Te Inenga

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.

Pātene Mahi

• NGA WAIATA: Press to toggle between Foot-candles (Fc) and Lux units.
• PANUI: Press to manually select the measurement range. The meter also has an auto-ranging feature.
• MAX/MIN: Press to display the maximum or minimum light reading recorded since the meter was powered on or the function was reset.
• TE MAUNGA: 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.
• KAUPAPA: Freezes the current reading on the display. Press again to release.
• RAMARAMA TUARUA: Press the light bulb icon button to turn the display backlight on or off for improved visibility in low-light conditions.

Te tiaki

Te horoi

• Wipe the meter and sensor with a dry, clean, soft cloth.
• Kaua e whakamahi i nga kai horoi me nga whakarewa.
• Keep the light sensor clean and free of dust or smudges to ensure accurate readings.

Whakakapinga Pūhiko

When the battery indicator appears on the display, replace the 9V battery as described in the "Battery Installation" section under Setup.

Rokiroki

• If storing the meter for an extended period, remove the battery to prevent leakage.
