a) Disconnect any test leads from external devices.
b) Press the
key to select thermocouple and RTD/
Ω
mode, if
not already selected. If RTD/
Ω
mode is displayed, press the key
again to cycle to thermocouple mode.
c) If input mode is displayed, select output mode by pressing the
and
keys.
d) Press the
key to select the desired thermocouple type or
the millivolt range.
e) Connect the unit under test to the thermocouple terminals of the
CL3001 using a standard T/C miniplug as shown in figure 15.
One pin is wider than the other; do not attempt to force the plug
in the wrong polarization. The T/C wire used for the connection
must match the thermocouple type selected for proper cold
junction compensation. If the CL3001 and the T/C miniplug are
at different temperatures, wait at least 3 minutes for the miniplug
and terminals to stabilize to the same temperature.
