1.  The specification above is specified after 60 minutes of warm up time. If the unit is exposed during storage in high humidity (condensing)
environment, 120 minutes of operating time is required instead.
2.  The accuracy does not include the tolerance of the thermocouple probe.
3.  Do not allow the temperature sensor to contact a surface that is energized above 30 Vrms or 60 V DC. Such voltages poses a shock hazard.
4.  The temperature calculation is specified according to the safety standards of EN/IEC-60548-1and NIST175.
5.  The approximate ambient temperature (cold-junction compensation) is shown on the display when you have an open thermocouple.The
open thermocouple message may be due to broken (open) probe or because no probe is installed into the input jacks of the multimeter.
6.  For temperature measurement on U1233A, the type-K thermocouple probe and adapter such as the U1186A (purchase separately) is
required.
7.  For auxillary temperature measurement on U1231A & U1232A, a temperature module such as the U1586B (purchase separately) is required.
