Selecting Total Harmonic Measurements

 Press the key until the THD or TDD LED is illuminated. Use the

up/down arrow keys to scroll through the different harmonic parameters.

Selecting Energy Measurements

 Press the key. Use the up/down arrow keys to scroll through the

different energy readings.

Fast Reset of Accumulated Data

 Select a display page where the data you want to reset is displayed. To reset:

• Min/Max log registers: select a Min/Max page from the Min/Max

measurements display (where a MAX or MIN round LED is illuminated).

• Ampere and volt maximum demands: select the ampere or volt maximum

demand page from the Min/Max measurements display (where a MAX DMD

LED is illuminated, and volts or amps LEDs at the right are lit).

• Power maximum demands: select the power maximum demand page from

the Min/Max measurements display (where a MAX DMD LED is illuminated,

and kVA/MVA and kW/MW LEDs at the right are lit).

• Total and phase energies: select the energy measurements display.

 While holding the key, press and hold for about 5 seconds.

The displayed data is reset to zero.
