Using the mA Sourcing (Output) Modes 

The  Calibrator  outputs  current  for  calibrating  and  testing  0  to  24mA  and  4  to 

20mA current loops and instruments. 

In 

SOURCE

 mode, the Calibrator supplies the current. 

In  SIMULATE  mode,  the  Calibrator  simulates  a  2-wire  transmitter  in  an 

externally-powered current loop.

 

 

Changing the mA Output Span 

The Calibrator has two mA output spans: 

l

 4mA to 20mA ( 0% to 100% ) [default] 

l

 0mA to 24mA ( -25% to 125% ) [optional] 

 

Sourcing mA 

Use 

SOURCE

 mode to supply current to a passive circuit. 

A  path  must  exist  for  current  to  flow  between  the  +  and 

COM

  terminals. 

Otherwise the display indicates an

 when you set an output value.
