Using the Current Output Functions
25
Manually Stepping the mA Output
When the rotary 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 step the current up and down in 25% steps
as shown in Table 9. See Table 10 for mA values at each
25% step.
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 COARSE and FINE adjustment pushbuttons
described on the previous page are available
when you are manually stepping the mA output.
