Procedure
Use the following procedure to connect the BetaPort–
DC electrical module to a field device:
NOTE: Install the module in the calibrator prior to
connecting the module to field devices.
1.
Insert the common pin (marked by a tab) on the
dual banana connector into the negative (black)
terminal marked with a "–" on the module.
2.
Insert the opposite pin into the positive (red)
terminal marked with a "+" on the side labeled "V"
for voltage measurement and "mA" for milliamp
measurement.
NOTE: The BetaPort– DC module is protected from
damage against misconnection to high voltages
up to 120 Volts. In the event that the module is
misconnected to a high voltage, the module
should be checked for correct operation by
comparison with another device of known
performance and similar or better accuracy.
