How to Reset and Program Thermocouple Type (or RTD)

How to Reset and Program Thermocouple Type (or RTD)
A DPS3301-TC that is calibrated for a J, K, T, or E type thermocouple or an RTD model may be A DPS3301-TC that is calibrated for a J, K, T, or E type thermocouple or an RTD model may be
programmed for a specific thermocouple, or RTD (385/392) type, by going into SETUP mode (Look under programmed for a specific thermocouple, or RTD (385/392) type, by going into SETUP mode (Look under
'SETUP'). Alternately, a thermocouple/RTD may be selected by turning On power to the unit while holding 'SETUP'). Alternately, a thermocouple/RTD may be selected by turning On
in the appropriate key (see Figure 1). This procedure also clears the memory and programs factory defalult
values for limits, rate timebase etc. Therefore, after performing Power-up reset, various parameters such as
limits, rate time base etc., must be re-programmed to a desired value. However, if done in SETUP mode, no
programmed parameters such as limits, Timers etc. are erased from the memory. It is recommended that
thermocouple (RTD) selection be done in SETUP. Power-up reset should be performed if it is suspected that
program memory may have been corrupted due to power surge, noise on electrical lines etc.
