RT1 can be measured by the EX1200 DMM or may be measured using an external instrument. If
an external sensor is used, it must be connected to T163 (L_VS) and T164 (H_VS). The user may
also choose to use a sensor other than the on-board thermistor. To do so, connect the sensor using
T161 (RL_I) and T162 (RH_I). Note that CH1_1L (T1) and CH1_1H (T2) must be dedicated to
making temperature measurements once P2 is configured.
