Similarly in under-rangecondition (-5% of instrument span) xxxxx will be ‘-----’. In the case of a system error R1 will be replaced by the error code e.g. ? 72 In verbosemode a brief fault description will be appended. ‘Conc’ & ‘%’ are determined by sensor type and unit – see ‘U’ below. Resolution is applica-tion dependant. Where a fault is present in the secondary reading it will be indicated by a text description in verbose mode and by a code inthe case of Zr units (heater does not return a numeric value in R4) or by -999 or +999 to indicate downscale or upscale failures respectively.AxUy Unit(read only)U13 Test Flags=0 U13=0U12 Factory Flags=0 U12=0U11 Output=mA* U11=1 Analogue output: 0=4/20mA,1= 0/1V, 2 = 0/5V, 3=0/20mAU10 Sens 2 Ch=1 U10=1 Sens 2 ADC chan (9)U9 R2 unit=mV U9=2U8 R2 type=T/C U8 =14U7 R1 Ch=1 U7 =1U6 R1 unit=% U6 =1U5 R1 type=Z U5 =13U4 F/w rev=0.24 U4 =0.24U3 F/w p/n=290-6031 U3 =290-6031U2 S/n = I-700123 U2=I-700123U1 Addr=0 U1 =0 Sensor Card Address
