The JL1700 is a very sophisticated microprocessor based, computer controlled current and conductance uv meter that maintains 0.1 percent linearity over most of its extremely wide dynamic range. This current reading range spans from less than 0.3 pico amperes to 2 ma with 3 digit resolution, allowing a spectral range of 190 nm to 3.5 microns with unmatched resolution, accuracy, and reliability. The JL1700 is capable of auto-ranging in the D.C. direct measurement mode as well as in the integration mode over the entire 9 decade range. The automatic zeroing feature is complemented by the ability to set a 100 percent value for simple measurements in percentages of the measured maximum and for differential (percent change) measurements. Multiple input power selection, computer interface, analog recorder output, and remote computer control are all standard features. These versatile features allow the JL1700 to be used in numerous applications. To accommodate demanding operating environments, this model can be operated within a temperature range of 0 to 40 degrees Celsius or even greater ranges with the remote detectors. The JL1700 maintains complete compatibility with a multitude of detectors, attenuators, filters, and diffusers.
