Yes: indication of the internal temperature although the external
sensor is connected
Note 1: The stated accuracy in external temperature measurement does not take into account the accuracy of the K
thermocouple.
Note 2: Operation of the thermal time constant (0.7 min/°C):
If there is a sudden variation of the temperature of the multimeter, by 10°C for example, the multimeter will reach 99% of
the final temperature at the end of 5 time constants, or 0.7min/°Cx10°Cx5 cts = 35 min (to which must be added the constant
of the external sensor)
