viva 1.0 (for Process analysis)
Designation Description Commands
OVS Value of the output at the start of the command. Direct controller/2-point con-
troller command status: 1 = active, 0 = inactive
PID/PWM: -100 to 100% (value of the analog output or the pulse frequency)
CONTROL
PK{x}.ABS Absorbance of the peak x (1 - 9) in mAU MEAS Spec
PK{x}.TRN Transmission of the peak x (1 - 9) in % MEAS Spec
