Operators Manual
desired current into the calibrator. For example, press "1 A"
menu appears:
Because the calibrator is now set up to output current, any previously created wave is
removed. A new wave can be created by pressing the SET WAVE blue softkey. The
menu shown below appears.
Press the NEW WAVE or EDIT WAVE blue softkey. The menu shown below appears in
the Control Display.
From this menu, the user may edit the wave harmonics. Refer to "Creating Wave
Harmonics" earlier in this section.
How to Set LCOMP
The LCOMP blue softkey enables/disables internal compensation for inductive loads
such as multi-turn coils. Refer to "Setting AC Current Output" in Chapter 4 of this
manual for a detailed discussion of this feature. Note that setting LCOMP to "on"
degrades the accuracy of higher frequency harmonics as indicated in the specifications.
Output AUX
This indicator is for information purposes only. The indicator displays which current
output is presently being used by the calibrator. The Control Display will show the
Output Information Menu (I OUT AUX when current is present at the AUX output and I
OUT 20A if the current is present at the 20A output).
In the PQ mode, the operation of the Output Information Menu behaves slightly different
than in the normal operating mode described in Chapter 4. In the Composite Harmonic
mode, the calibrator does not update the Output Information Menu until the waveform is
built. For example, if the calibrator is presently set at 10 A, 60 Hz, with STBY showing
in the Output Display, and the user wishes to output 1 A by pressing "1A
Output Information menu will not automatically change to OUTPUT AUX until
pressed.
When in the SET WAVE menus, the Output Information menu is not shown. In those
menus, if
