    MODEL 346 INSTALLATION AND OPERATION MANUAL 5.6 DERIVED VARIABLES 5.6.1 INTRODUCTION The derived variable feature provides basic and specialised maths functions. These functions combine channel inputs, user-entered constants and pre-configured equations to derive variables which may be viewed, recorded and/or used in other calculations.There are two classes of DV: basic and specialised. Because of processing time allocations, only two specialised DVs can be used at any one time.
