numberings in RM indicates the number of stored data in current mode (cond/TDS). For example, if 20 groups of data is stored in conductivity mode, and 10 groups in TDS mode, then the numberings for M+ will be “M+30” in both conductivity and TDS mode; the numberings for RM in conductivity mode would be “RM20”, in TDS mode “RM10”. -

4.5 TDS and Conductivity 4.5.1. TDS and conductivity is linear related. The conversion factor is 0.40-1.00. Adjust the factor from parameter P2.6. The factory default setting is 0.71 and please refer to Section 7.4. The meter only needs to be calibrated in Conductivity mode, then after calibration of conductivity, the meter can switch from conductivity to TDS. -
