Charging The Battery; Button Functions - AEMC PowerPad 8335 Quick Start User Manual

Charging the Battery

Fully charge the battery before the first use.
The batteries automatically begin recharging when the instrument is connected to AC power.
Only use the supplied AC power adapter to recharge the batteries.
NOTE: A full recharge of a completely discharged battery takes 5 hours approx.

Button Functions

BUTTON
Return to the choice of measurement view.
Configure the PowerPad
Take a snapshot of the current screen or access screens already stored in the memory.
Record associated waveform and power measurement data.
Get help on the current display functions, in the language chosen by the user.
Transients or Inrush Current:
• Sets and views transient and inrush current waveforms associated with rapid changes in input
Harmonics Mode:
• Displays the harmonics in percent and value ratios for voltage, current and power for each
harmonic through the 50th
• Determines harmonic current produced by non-linear loads
• Analyzes the problems caused by harmonics according to their order
(heating of neutrals, conductors, motors, etc)
Waveforms Mode:
• Displays voltage and current waveforms or vector representation
• Identifies signal distortion signatures
• Displays of amplitude and phase unbalance for voltage and current
• Checks connections for correct phase order
Alarm Events:
• Provides a list of the alarms recorded according to the thresholds programmed during
configuration
• Logs interruption with half-cycle resolution
• Determines energy consumption exceedances
• Stores value, duration, date, time and set point for up to 4096 events
Trend Mode:
• Lists all recording trends and views them on the display
(Urms, Vrms, Arms, etc)
Power / Energy:
• Displays power levels and the associated parameters (power factor, displacement and tangent)
• Energy monitoring
• Four quadrant measurement to discern produced/consumed active energies and inductive/capaci-
tive reactive energies
120V ± 10%, 60Hz
230V ± 10%, 50Hz
DESCRIPTION
