Measurements using calibrator’s internal power supply for powering the 

loop 

The calibrator provides an internal 24 V power supply for measuring the signal of 

2-wire transmitters (sink transmitters). The 24 Vdc is applied between terminals 

+LOOP  e  COM. The sink transmitter is to be connected between terminals 

+LOOP (Power supply output) and mA (terminal for the loop current monitoring). 

1.

 

Press the power switch 

  to 

turn on the Calibrator. 

2.

 

Choose OUTPUT mode   by 

pressing the INPUT  /  OUTPUT 

key  . 

3.

 

Press the mA / mA % mode key 

  to choose the desired unit. 

The sings mA or mA % 

 will 

be presented on the display. 

4.

 

Plug the red test lead into the 

LOOP  jack 

  and the  black 

one to the mA jack  . 

5.

 

Connect the test leads such that 

the current enters the red lead 

and returns to the power supply 

through the black lead. 

6.

 

The measurement is shown on 

the display  . 

 

 
 

DC mA generation 
a)

 

Sourcing mA 

1.

 

Press the power switch    to 

turn the Calibrator ON. 

2.

 

Press the input  /  output mode 

key 

  to select OUTPUT 

mode  . 

3.

 

Press the mA / mA % mode key 

 to select mA or mA %  . 

4.

 

Press the increment 

decrement keys   

   

 

to set the desired output value. 

5.

 

Plug the red test lead into the 

LOOP  jack 

  and the black 

one to the V jack  . 

6.

 

Connect the test leads such that 

the current enters the red lead 

and returns to the power supply 

through the black lead. 

7.

 

To change the output value, 

press the increment / decrement 

keys 

 

 

 

  and  /  or 

the mA mA % mode key  .
