AI 835A THERMOCOUPLE MODULE
AI835A module is used for k type thermocouple and 8th channel is used as normal Thermocable input as same as 1 to 7 channel. In parameter setting as follows.
Fix junction temp=35degc
All 1 to 8 channels =active
Cold junction compensation for all channel=fixed as parameter.
But the problem is when room temp change due to air conditioner or ambient changes its effecting to all 8 measurement, in short fixed CJ is not applying.
Pl.help me for how to fix this.
One channel (channel 8) can be configured for “Cold Junction” (ambient) temperature measurement, thus serving as the CJ-channel for the other channels on the module. All 8 channels can be used if no CJ-temperature measurement is needed.
To measure cold junction Temperature, use TY820.
