There are 8 modes (J-type, K-type, R-type, S-type, T-type, E-type, N-type, 0~150mV) for each channel which can be set up separately. For example, if the user needs to set up CH1: mode 0 (b2 ~ b0 = 100); CH2: mode 1 (b5 ~ b3 = 001); CH3: mode 0 (b8 ~ b6 = 000) and CH4: mode 1 (b11 ~ b9 = 001), CR#1 has to be set as H0208 and the higher bits (b12 ~ b15) is CH1~CH4 Disable/Enable.
