DISPLAY Indications
1. On the first power up the display shows the firmware version and factory preset data port
mode.
2. Sampling time setting
3. Measured Data Displays
The data in the scrolling quadrant: Time period in use, Ah(Amp Hour), WH(Watt Hour), Vp(max
voltage), Ap(max.current), Wp( max.Watt), Vm(min.Voltage), Negative: -Ah, -WH, -AP,-Wp back to
Time period in use, can be fixed and released by one quick press of the Reset button.
Current (Amps A, Peak Amps Ap, - Amps):
The Amps value is the average current through the Meter's black wire over the last screen update
interval.
Ap is the Peak (maximum) is current to the LOAD side, since the start up screen to the present
moment. Similarly for negative Ap.
Voltage (Volts V, Maximum Voltage Vp Minimum Voltage Vm):
The Volts value is the average voltage over the last screen update interval.
Vp is the Peak (maximum) voltage & Vm (minimum) from the source side since start up screen to
the present moment. There is no negative Vp or Vm registered .
Charge (Amp-hours Ah , negative amp hour Ah):
Ah is total amp-hour delivered to the battery while negative Ah is the total Ah discharge from
battery since start up synchronized with the internal clock of the MCU.
Energy (Watt-hours Wh and negative Watt hour ):
Wh is total watt-hour delivered to the battery while negative Wh is the total Wh discharge from
battery since start up synchronized with the internal clock of the MCU.
Power (Watts W, Peak Watts Wp, negative Watts W, negative Peak Watt):
The W value displayed is the average power delivered to the battery wie negative W is the
discharge W from the battery over the last screen update interval. The displayed Peak Watts value
(Wp) is the maximum power delivered to the battery and negative Wp is the maximum power
discharged from battery...
