LUX METER FT3424 Environmental measuring instruments Broad coverage from low to high illuminance Measure at 0.01 lx resolution to a maximum of 200,000 lx Compatible with LED lighting • Complies with DIN Class B and JIS Class AA • Save up to 99 measured values in the instrument’s internal memory and transfer them to a computer later for improved work efficiency • Timer hold function lets you make measurements in remote locations while avoiding the effects of shadows and reflections 2 Support for measurement of 1 lx makes the FT3424 ideal for low-illuminance measurement 20 lx range measurement resolution 0.01 lx 1. Timer hold function Retain the measured value after a user-configured amount of time has elapsed from the time the TIMER key is pressed. In this way, you can time measurement to occur after you have moved away from the lux meter so that measurement is not affected by clothing, shadows, etc. Measurement delayed until operator is out of the way Effect of shadow Timer settings Select from 5 / 10 / 15 / 20 / 30 / 45 / 60 sec. Remaining time display Counts down with timer. After the set time has elapsed The measured value is retained. → The backlight turns on and the beep sounds for 3 sec. 2. Measurement with sensor and display units undocked Large, easy-to-see LCD display The backlight turns on automatically whenever a measured value is retained in a low-illuminance environment. Connection Cable L9820(Option) Relative Spectral Response Characteristics in the Visible Spectrum Angled Incident Light Characteristics Human perception of brightness ranges from 380 nm to 780 nm in the wavelength and is the maximum at 555 nm. The lnternational Commission on Illumination (CIE) has established comparative standards for luminosity, setting the maximum perception for 1 and indicating the amount of perception of each wavelength by the relative value, and calculating the average of many people. In this instrument, the relative spectral response characteristics are close to the comparative standards for luminosity. It is known that the luminance is proportional to the cosine of the incident angle of light (the cosine law). In this instrument, the shape of the light sensor, hook etc. is so made that it can follow the cosine law closely. Graph illustrates typical characteristics.Characteristics exhibited by individual products may vary slightly. 3 DIN Class B and JIS Class AA compliant for optimal reliability Key feature Memory function makes multipoint measurement a breeze 1 Memory function (up to 99 values) Save in the field Save measured values for multiple measurement locations in the instrument’s internal memory on the spot for later display at your convenience. 2 Data communications functionality Transfer to your PC Transfer data saved in the instrument’s internal memory to a computer via a USB connection. Data can be saved as a text file. Press the MEMORY key. When making measurements at numerous locations, this feature lets you save values on the spot and then create a report later in the office at your convenience.
