Using the Current Output Functions
Manually Stepping the mA Output
Table 9. mA Stepping Pushbuttons
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
display. When the impedance between the SOURCE jacks is low enough, the meter will resume sourcing.
