ALCT3 - USB Based Automatic Liquid Crystal Tester Technical Specifications Output Wave DC to 10KHz, voltage 0 to ±100V Output Update Rate 500KHz Output Resolution 16 bit Input Resolution 16 bit Input Sample Rate 500KHz Current Measurement Range 1nA ~ 1mA Current Sensing Resistance 10K, 100K, 1M, and 10MΩ Current Resolution 100pA Post Gain in the ALCT Box 1, 10, 100, 1000 Capacitance Measurement 2pF to 100nF Easy-to-Use Software, WinLC The ALCT3’s software has been designed to be both flexible enough for academic research and yet simple enough to use for easy incorporation on the factory floor. For instance, in the Nematic Liquid Crystal measurement application the data chosen to analyze for the determination of the dielectric constants ε || , ε ⊥, the elastic constants K11, K33, and the threshold voltage can all be chosen by the user. Alternatively by the changing of a single setting they can be fixed to default values to insure repeatable meaningful results.
