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.
