• The thermocouple check feature allows you to verify that your
thermocouples are properly connected to the screw terminals for
measurements. If you enable this feature, the instrument measures
the channel resistance after each thermocouple measurement to
ensure a proper connection. If an open connection is detected (greater
than 5 k on the 10 k range), the instrument reports an overload
condition for that channel (or displays "OPEN T/C" on the front
panel).
• Front-Panel Operation: To select the thermocouple function on the
active channel, choose the following items.
TEMPERATURE , THERMOCOUPLE
