Details
For temperature measurements, this is only available when the transducer is set to a thermocouple or
one of the RTDs.
Long lengths of thermocouple wire can have a large amount of capacitance, which is seen at the
input of the DMM. If an intermittent open occurs in the thermocouple circuit, the capacitance can
cause an erroneous on-scale reading. The open thermocouple detection circuit, when enabled,
applies a 100
µ
A pulse of current to the thermocouple before the start of each temperature
measurement.
Example
TEMP:TRAN TC
TEMP:TC:TYPE K
TEMP:UNIT C
TEMP:ODET OFF
Set the transducer type to thermocouple.
Set the thermocouple type to K.
Set the units to Celsius.
Turn open lead detection off.
