V Choose a system of units suitable to your application from the following standard list, or as an option, we will calibrate your detector to any nonstandard units you specify. We can also customize detectors for your unique application. The IL1400A comes complete with a rugged carrying case to protect the instrument, detectors, filters, input optics and accessories from abuse out in the field. The 'ZERO' button allows the automatic subtraction of any undesired background light. This convenient function is necessary for accurate readings, since ambient and scattered light can contribute significantly to the overall reading.
Integration is used to measure the 'dose' or sum of all light reaching the detector over time.
The IL1400A is capable of exposure integrations of up to 24 hours in duration. This feature makes it much more convenient to take readings in the dark. Pressing the 'HOLD' button also tells the computer to send data to the optional TTL printer. LCD continuously displays data with full units and the present mode of operation. The menu driven Programming Mode allows experienced users to customize many of the IL1400A's features.
