Measurement Screen Glossary
Only the current from SOURCE to LOAD is measured. The Amp
value displayed is the average current over the last screen update
interval Peak Amp value (Ap) display is the maximum current drawn
from the LOAD side. Peaks lasting only a fraction of a second can
be captured. Supplying the auxiliary power with a voltage greater
than what the meter it is measuring removes the meter’s operation
current from measurements. To reduce heating, measure currents
over 65 amps from reduced time and consider using connector
which can handle large current.
The displayed 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. The
volts value is measured on the SOURCE side.
The displayed value is the total energy delivered in watt-hours and
it is measured on the LOAD side. For best results, do not interrupt
the SOURCE connection to the watt meter during a charge
measurement.
The displayed value is the total charge in Amp-hours(x1000=mAh)
delivered since the startup screen and it is measured on the LOAD
side. For accurate results, do not interrupt the SOURCE connection
to the watt meter during a charge measurement.
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 are measured on the LOAD
side
