You can reverse the order by first pressing the SHIFT key followed by the FUNCTION key.
Display Range and Units
Display range: G180.0 to d180.0 (G meaning phase lag, d meaning phase lead)
Unit: deg
Selecting the Display Function
When you select deg, the phase angle will be displayed.
Note
• Changing the measurement mode might result in different computed results, even when the
input signal is the same. For details on the measurement mode, refer to section 4.1.
• When either the voltage or current drops below 0.5% of the measurement range, dEGEr will
be displayed.
• Distinction between phase lag and lead can be made properly, only when both voltage and
current are sine waves, and when the percentage of voltage or current input relating to the
measurement range does not fluctuate much.
• If the computed result of the power factor exceeds 1, the display will be as follows.
• When the power factor is between 1.0001 and 2.0000 or between –1.0001 and –2.0000:
phase angle display is 0.0.
• When the power factor is greater than 2.0000 or less than 2.0000: phase angle display is
dEGEr.
