    2. Controls If you cover up the detector and press the ‘ZERO’ button, the unit will take a reading of this low level and subtract that reading from all future readings, thereby establishing the ‘ZERO’ reference condition. This ‘ZERO’ can be any reference level, such as the ambient room illumination.

    The ILT1700 is capable of integrating energy in a flash of light transmission plot of the sample filter. A 100% reading must at microsecond speeds as well as int egrating for over eighteen be established at each wavelength since the source/ years, and everything in between.(with some limitations).

    Any integration longer than one second is considered As mentioned above on the subject of multiple flashes, long term integration. In this state, the ILT1700 keeps up the system can be used to find the average of many flashes. with the incoming signals, and presents an updated readout This is done by integrating throughout many flashes.

    4. Outputs 4.2.1 Voltage Range The voltage is designed to be compatible with most strip chart and X-Y recorders, and yet provide a large enough signal to avoid excessive noise pickup. For these reasons, 4.1 LCD Displays we have selected a range from 0 to 1.0 volt (1000 There are actually 12 positions that are computer millivolts).
