Using the Current Output Functions

The meter provides steady, stepped, and ramped current

output for testing 0-20 mA and 4-20 mA current loops.

You can choose source mode, in which the meter

supplies the current, or simulate mode, in which the

meter regulates current in an externally-powered current

loop.

Source Mode

Source mode is selected automatically by inserting the

test leads into the SOURCE + and − jacks as shown in

Figure 7. Use source mode whenever you need to supply

current into a passive circuit such as a current loop with

no loop supply. Source mode depletes the battery faster

than simulate mode, so use simulate mode whenever

possible.

The display looks the same in source and simulate

modes. The way to tell which mode is in use is to see

which pair of output jacks is in use.
