Description

(Current) Amps & Peak Amps A, Ap

Only current from SOURCE to LOAD is measured. Amps value displayed is the average current over the last screen update interval. Peak Amps value (Ap) displayed is the maximum current drawn from the LOAD side, since the meter’s startup. Peaks lasting only a fraction of a second, can be captured. Supplying the auxiliary power with a voltage greater than the meter is measuring, removes the meter’s operation current from measurements. To reduce meter heating, measure currents over *5 Amps for reduced time and consider using connectors which can handle large current.

(Voltage) Volts & Minimum Volts V, Vm

The displayed volts value is the average voltage over the last screen update interval. The displayed Minimum Volts value (Vm) is the minimum voltage (or “sag”) measured on the SOURCE side, since the startup screen ended. The Volts value is measured on the SOURCE side.

(Energy) Watt-hours Wh

The displayed value is the total energy delivered in Watt-hours since the startup screen ended. It is measured on the LOAD side. For accurate results, be careful not to interrupt the SOURCE connection to the Watt Meter during an energy measurement.

(Charge) Amp-hours Ah

The displayed value is the total charge in Amp-hours (x***0=mAh) delivered since the startup screen ended. It is measured on the LOAD side. For accurate results, be careful not to interrupt the SOURCE connection to the Watt Meter during a charge measurement.

(Power) Watts & Peak Watts W, Wp

The displayed value is the average power delivered in watts (=Volts x Amps) over the last screen update interval. The displayed Peak Watts value (Wp) is the maximum power drawn on the LOAD side, since the startup screen ended. Watts values are measured on the LOAD side.
