Technical Specification2604 ControllerC. Appendix C Technical SpecificationAll figures quoted at 0 to 50 o C unless otherwise stated.C.1.Sample rateInput filteringUser calibrationSensor breakThermocoupletypesGeneralALL ANALOGUE, DUAL AND PV INPUTS9Hz (110msec.)OFF to 999.9 seconds of filter time constant (f.t.c.). Default setting is0.4 seconds unless stated otherwiseBoth the user calibration and a transducer scaling can be applied.a.c. sensor break on each input (i.e. fast responding and no dc errorswith high impedance sources).Most linearisations including K,J,T,R,B,S,N,L,PII,C,D,E withlinearisation error < ±0.2°CResolution (noise free) is quoted as a typical figure with f.t.c. set to thedefault value = 0.4 second.Resolution generally improves by a factor of two with everyquadrupling of f.t.c.Calibration is quoted as offset error + percentage error of absolutereading at ambient temperature of 25 O CDrift is quoted as extra offset and absolute reading errors per degree ofambient change from 25 O C.C-2 User Guide.
