SNAP-AIVRMS and SNAP-AIARMS module readings may become fixed at -32768 APPLIES TO SNAP-AIVRMS SNAP-AIARMS SYMPTOMS SNAP-AIVRMS and SNAP-AIARMS module readings may become fixed at -32768. The low scale for these modules is zero, and they should not report negative values that are less than 0.5% of full scale (-1.25 V for the SNAP-AIVRMS module, and -50 mA for the SNAP-AIARMS module), unless there is an error condition. OptoKB Article Last Review Revision : KB47789 : April 25, 2006 : 3.0 RESOLUTION Module firmware has been updated to correct this problem. If you are experiencing the above symptoms, contact Opto 22 Product Support to discuss a solution. MORE INFORMATION If you are using a serial B3000 brain, also see OptoKB KB48056.
