1D-C * Description: Optical Array Probe (1D-cloud) * Manufacturer: Particle Measuring Systems Inc. * Model: 230X * Serial Number: Problem Very high counts in random channels of the 1-DC. This would occur even when the DC power was off. The spectrum would look good in cloud; except for some random high counts in some channels. The problem seem to started with the switch to the new M300 data system and last upto and including the Sikorsky ferry flight to Alaska (September 13, 2005).
