Display Parameters
The display screen will continuously measure and display Amps, Volts and Watts. All other values are presented sequentially every second. In the lower left position of the display, data values are identified by their units (Ah, Wh, Ap, Vm, Wp).
Voltage & Minimum Volts (V, Vm)
The displayed Volts (V) value is the average voltage from the last screen refresh. The displayed Minimum Volts (Vm) value is the minimum voltage or sag measured on the source side, since the meters last startup.
Watt-hours (Energy) (Wh)
The displayed value is the total energy delivered in Watt-hours since the meters last startup. It is measured from the load side for the most accurate results.
Amp-hours (Charge) (Ah)
The displayed value is the total charge delivered in Amp-hours since the meters last startup. It is measured from the load side for the most accurate results.
Watts (Power) & Peak Watts (W, Wp)
The displayed Watts (W) value is the average Watts (Amps * Volts) from the last screen refresh. The displayed Peak Watts (Wp) value is the maximum watts measured since the meters last startup.
