the AC adaptor, check that the adaptor is connected correctly to the meter and to an AC
source (refer to the AC Power Adaptor section later in this guide).
Connecting Thermocouple Sensors
This meter can accept Thermocouple temperature probe Types K, J, T, E, R, or S.

Connect up to twelve (12) thermocouples to the sub‐miniature jacks at the top of the meter
labeled T1 through T12.

Select the desired mode of operation, and other setup features, in the Setup Mode. Refer to

IMPORTANT NOTE: The supplied thermocouple probes are useable in the range of ‐20 to +250°C
(‐4 to +482°F) only; even though the meter can display temperature values outside of this range.
For measuring outside of the range specified here, please obtain thermocouples rated
accordingly.
