BEAMEX MC5-IS - Voltage Measurement; Measuring Low Voltages

40
Startup and Basic Operation
Voltage Measurement
The E module has terminals for low voltage measurement within the range ±250 mV and
terminals for voltage measurement within ±30 V range. The ET module also has low volt-
age measurement terminals with a range of ±250 mV. The ET module terminals are also
used when measuring/simulating thermocouples using an external Reference Junction.
Required settings Options/description
Quantity Voltage
Funct/Port ET: LowV(mea), E: LowV(mea) or E: V(meas)
MC5-IS displays the measured low voltage in the selected window.
Hint!
Low voltage measurement can be used for non-standard thermo-
couple measurement. You will see the measured temperature in
millivolts and need a table to convert the measured millivolt value to
corresponding temperature values. In this case, use copper exten-
sion cords to connect the non-standard thermocouple to MC5-IS’
terminals.
Measuring Low Voltages
Select either Function/port ET: LowV(mea)
or E: LowV(mea) and choose a suitable
unit. The following pictures display the ac-
tive terminals for both available ports.
ET: LowV(mea), ±250 mV:
E: LowV(mea), ±250 mV:
