Brief Introduction：

1. Make sure the wattmeter is series-wound working in the

circuit, :“IN”—Input “OUT”—Output LED displays Voltage

（U）,Current（I） and Power（P）

2. Watt display when power on.

Data comparing mode：

Press the blue button after power on, The wattmeter will work on date

comparing mode,(HOLD mode)with this function, the wattmeter records:

“P” means the max power, Um means min voltage. and Im means max

current .

Up and Ip means the max voltage and max current corresponding to

the max power. All the data will remain unchanged unless power off or

higher watt measured.

Attentions：Current display is susceptible to intense magnetic field

Manual calibration function：

After power on, keep pressing the button for 3 seconds, then the

wattmeter works on manual calibration function. Then there are 4 options

and one data displayed. “11333” means the voltage of the power supply is

11.333V. “ADD” and “SUB” are used to increase and reduce voltage

display，“SAVE” is used to save the calibration.

“LOAD” is to pick up the data setting made last time. The P1 will jump to

next option at each 3 seconds. When jumping to the option that you want,

press the button to submit the selection. It is suggested to adjust the

value according to a voltage measuring instrument to minimize the error, such as a good quality multi-meter when

trimming. Select "ADD" or "SUB" for trimming. Then select “SAVE” to save the calibration. Now manual calibration

is finished, turn on again, and wattmeter works with precise data displaying. Trimming is not suggested without a

professional voltage display device.
