When measuring electric current, an important thing is selecting whether MC6
provides the 24 volt loop supply voltage or not. If not, an external device
should provide the loop supply voltage.
Connection depends on the loop supply setting. See pictures to the right.
See also: Current Generation (Source or Sink) on page 24.
MC6's voltage measurement terminals are listed below (top to bottom) as they
are shown in the adjacent picture (left to right):
TC1, measurement range: -1.01 to +1.01 VDC.
TC2, measurement range: -1.01 to +1.01 VDC.
IN, measurement range: -1.01 to +60.6 VDC.
Note that you may measure non-supported thermocouple signals using either
TC1 or TC2 port. The reading is in (milli)volts, so you need a data table to con-
vert the signal to temperatures. Calibrator‘s and Documenting Calibrator's
Scaling utility may be used for converting millivolts to temperatures.

Warning!
Do not apply hazardous voltages to MC6's terminals.
