generating a 60-Hz signal, and the NORMAL output is generating a 120 Hz (2nd
Harmonic) signal, a phase shift of 60° (PF of .5) would move the AUX signal 60° of
120 Hz (30° of 60 Hz).
How to Enter a Phase Angle
Complete the following procedure to enter a phase shift in degrees. This procedure
assumes you have already sourced a dual ac voltage or ac power output.
1. Press the softkey WAVE MENUS, opening the harmonic menu.
2. Press the softkey Φ & REF MENUS, opening the phase and reference entry menu.
3. Press the softkey AUXΦNRM, opening the phase entry menu.
4. Press the numeric keys and decimal point key to enter the desired phase angle
(maximum five numeric keys). For example, 123.45.
5. Press I to select leading (+) or lagging (−) phase shift (default is +).
6. The Control Display now shows the value of your entry. For example, a leading
phase angle of 123.45 degrees (below). (SHOW PF appears only for sine waves.)

7. Press E . The calibrator clears your entry from the “New phase =” line and
copies it to the “Phase =” line of the Control Display.
8. Press G one or more times to return to previous menus.
How to Enter a Power Factor
Complete the following procedure to enter a phase shift as a power factor (PF).
PF = Cosine Φ, where Φ is the phase shift. This procedure assumes you have already
sourced a dual ac voltage or ac power output using sine waves as the waveform.
1. Press the softkey WAVE MENUS, opening the waveform menu.
2. Press the softkey PHASE, opening the phase entry menu.
3. Press the softkey SHOW PF, opening the power factor entry menu.
4. Press the decimal point key and numeric keys to enter the desired power factor
(maximum three numeric keys). For example, .678.
5. Press the softkey PF to toggle between a leading (lead) or lagging (lag) power factor
(default is lead).
6. The Control Display now shows the value of your entry. For example, a leading
power factor of .678 (below).
