5. After you have finished selecting the values on the first page, display the second page of values by pressing the
button ("2/2" will appear in the lower left corner of the display). These variables include U-h (phase-to-phase
harmonics), V-h (phase-to-neutral harmonics), A-h (phase harmonics), and VA-h (apparent harmonics).

The battery may fully discharge when the instrument is recording for long periods of time while not connected to a power supply.
The Model 8435 will continue to record for some time, even if below the minimum battery charge value. However, the display may
not come back ON, and the instrument will eventually stop saving data when the battery is too low. All data recorded will be saved.
If the instrument is in the Record Mode, and the display does not come ON, do not turn the instrument OFF. Supply power to the Model
8435 with the power cord and the display will come back ON when any button (other than ON/OFF) is pressed.
