Producing a Steady mA Output 
When the rotary function switch is in the OUTPUT [ mA 
position, and the OUTPUT jacks are connected to an 
appropriate load, the meter produces a steady mA dc 
output. The meter begins sourcing or simulating 0 %. Use 
the pushbuttons to adjust the current as shown in Table 8. 
Select either sourcing or simulating by choosing the 
SOURCE or SIMULATE output jacks. 
If the meter cannot deliver the programmed current 
because the load resistance is too high or the loop supply 
voltage is too low, dashes (-----) appear on the numeric 
display. When the impedance between the SOURCE jacks 
is low enough, the meter will resume sourcing. 
Note 
The STEP pushbuttons described Table 9 are 
available when the meter is producing a steady 
mA output. The STEP pushbuttons go to the next 
multiple of 25 %.
