With RTD input, the signal may go transiently to the opposite direction from the burnout setting.
With DC input, the burnout setting is ignored and the burnout sensing current is cancelled.
Cold junction compensation (CJC) for T/C input: CJC can be enabled or disabled per each channel.
CJC sensor attached to Input 1 and Input 7* terminals.(Input 7 for the 73VR2108, 73VR2110 and 73VR2112)
Operating mode setting: Application software; burnout type, cold junction compensation, line noise frequency, A/D conversion mode setting available
Line noise filter: NMNR ratio to the line frequency and its harmonic contents can be optimized. Factory set to 50/60 Hz mode for use with both frequencies.
Select either frequency for the most effective result.
