Adjustment
Manually Stepping the 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 step the current up and down in 25 %
increments 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.
The COARSE and FINE adjustment
pushbuttons described in Table 8 are available
when manually stepping the mA output.
