This easy to use meter is ideal for monitoring eight electrical parameters that are essential to electric
power safety and performance: Amps, Volts, Watts, Amp-hours, Watt-hours, Peak Amps, Minimum Volts
(Sag), and Peak Watts. With a capacity of up to 60 volts and 150amps, high contrast green backlit display
and auto reset feature, you’ll be sure find many great uses for this watt meter and power analyzer
High power electrical systems pose many dangers. It is the user’s responsibility to be familiar with these
dangers and take any action necessary to ensure safe use. Shorting a battery or battery charger can have
serious consequences including explosion, fire, damage to equipment, or personal injury. Exceeding the
rated specifications or shorting the watt meter will cause damage to the meter and void your warranty.
Initial Setup & Wiring
The red source wire goes to the positive (+) source or battery terminal. The black source wire (-) goes to
the negative terminal. Use caution when making connections to ensure all connections are tight use
adequate wire size to handle higher amps/current. This watt meter is available with either Anderson PowerPole® connectors
pre-installed or with bare wire ends for installation of your own type of connectors.
Watt Meter Display Screen
Each time power is applied to the watt meter (or the auxiliary power connector), the startup screen is
briefly displayed. Then the Amp-hours, Watt-hours, Peak Amps, Minimum Volts, and Peak Watts
parameters are all reset to zero.
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).
Amps (Current) & Peak Amps (A, Ap)
Only current from source to load can be measured. Drawing current in reverse will cause damage to the
meter. The Amps (A) value displayed shows the average current over the last screen refresh. The Peak
Amps value (Ap) displays the maximum current drawn since the meter’s last startup. Spikes or peak amperage readings lasting a fraction of a second may also be captured.
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 meter’s last
Watt-hours (Energy) (Wh)
The displayed value is the total energy delivered in Watt-hours since the meter’s 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 meter’s 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 meter’s last startup.
Auxiliary Power Connector Cable
By connecting the watt meter directly to a battery or power source, the meter requires a minimum of 6V to
power itself. However, if you are using the optional auxiliary power connector, the meter can be powered
through the auxiliary source, and measure the complete range of 0 to 60V. Another benefit of the optional
auxiliary power connector is that it powers the meter through the auxiliary source. The regular source to load
measurements become more precise, as the measurements do not include the small amount of power
required to operate the meter. Only 2 of the 3 wires on the auxiliary power connector are used. Refer to the
watt meter black housing for (+) and (-) indicators showing how to power the watt meter using the auxiliary
Connection Example Diagrams
Typical Load Testing
The following diagram shows the most common use of the watt meter, connecting a DC source like a battery
, solar panel or power supply (6-60V), to any DC load.
Load Testing Below 6 Volts
The following diagram shows the use of the auxiliary power connector which powers the meter externally and
allows voltage measurements down to 0V. This configuration also provides increased accuracy and lower loss
as power consumed by the meter is not included in the measurements. is pin1 and is Negative(ground). Pin 2
is positive. Pin 3 has no connection
The following diagram shows how a battery must be moved to the load side to measure battery charge,
as the power flows from the battery charger (source), to the battery (load).
