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)

The link to the COM input must be short and of large diameter, in order to limit the voltage drop that influences the
Volt measurement.
