DC Current Output
To set a dc current output:
1. Make sure the Calibrator is in standby (STANDBY annunciator lit). Push S if
necessary.
2. If the UUT is not connected, connect it now as described earlier in this chapter under
"Connect the Calibrator to a UUT."
3. Set the UUT to measure dc current in the appropriate range.
4. Enter a current value with the numeric keypad.
5. To change the polarity of the entry, push +.
6. Push U or N if necessary.
7. Push A.
8. The display now shows the amplitude of the entry. If an entry error is made, push C
to clear the display, then reenter the value. If the most recent digit entered is in error,
push Bto clear that digit. The illustration of the display below assumes an entry of
30 mA:
9. Push E. The Calibrator clears the entry from the entry bar toward the bottom
and shows in the larger area above. No current is available at the output terminals
until P is pushed.
10. Push P to activate the Calibrator output. The UUT will now respond to the
applied current.
