Mini Ammeter User Manual WF-D02A

Foreword

Thanks for choosing this product.

This product not only provides power connection for the electric appliances; but also

records operations of the appliances. Operation conditions on the display includes:

voltage of power supply, real-time running power, electricity consumption, electricity cost,

running time… At the same time, it provides analysis on real-time running power and

gives out alarm automatically once abnormal operation occurs. This helps to use and

maintain the appliances scientifically as well as save power and reduce waste. So, it is

also called “power-saving guardian”.

1. Connect the ammeter to an outer power supply, it starts working; the red indicator and

the LCD backlight are lightened immediately.

2. Insert the detection-waiting appliance into the ammeter, the ammeter starts real-time

detection for operation condition of the appliance.

3. Connect the ammeter to the power supply only, but disconnect it with any other

appliance, the following operations are still working:

Voltage of power supply can be measured;

Records of the former accumulated electricity consumption and cost can be read;

Relative functions and data can be set, including: electricity price, ratio of operation

condition, standby power.

4. Adaptable voltage: 220V/50Hz or 110V/60Hz (for different versions)

Peak load: 15 A

5. Limit to indoor use. Environmental Conditions: Temperature: -10 ~ 60 °C; Humidity:

10~95% RH

6. New functions:

1) Two ways for calculating operation time: time in single operation period and

accumulated time in all operation periods; can be manually cleared to 0.

2) Two ways for calculating power consumption and power cost: electricity

consumption and electricity cost in single operation period and accumulated electricity

consumption and electricity cost in all operation periods; can be manually cleared to 0.

3) Ratio of operation condition and standby power can be pre-set.

Display

ⅠDisplay scope:

1. AC Voltage: 160~280V/50Hz or 90~150V/60Hz (for different versions)

2. Power: 1~3000W (can display running power less than 1W.)

3. Electricity consumption: 0.0001 ~ 999.9 KWh

7. Measurement Accuracy: ±1%

8. Refresh rate: more than one time per second

Ⅱ

. Display Status：

1. Default display shows the voltage；

2. Ratio of operation condition: Ratio between accumulated running time per

hour (running power is over pre-set standby power) and 1 hour. The indicator

light will flicker when the real ratio reaches the set ratio.

3. Re-start this ammeter after power down, running time on the display restarts with 0.

4. The background light of LCD can Auto. Off after 15 seconds.

Ⅲ Display units:

1. AC Voltage: ×××× V ;

2. Accumulated electricity consumption: ×××.× kWh

3. Accumulated electricity cost: ××.×× $

3. Running Power: ×××.× W ;

4. Ratio of operation condition:×××%;

5. Time: ××:×× (hours: minutes)

××× D (days)

IV Buttons:

UP: Check data, add value, clear accumulated records into 0.

Press on “UP” button, the cursor on the top of the display will move to the left, and data

on the display changes accordingly to show different measured value; under set mode,

press “UP” button to add preset value; press and hold “UP” button for 10~15 seconds to

clear accumulated record into 0, including all accumulated records in all operation

periods.

DOWN: Check data, reduce value, clear records in simple operation period into 0.

Press on “DOWN” button, the cursor on the top of the display will move to the right, and

data on the display changes accordingly to show different measured value; under set

mode, press “DOWN” button to reduce preset value; press and hold “DOWN” button for

10~15 seconds to clear racords in single operation period into 0, including all calculated

records in single operation period.

MENU: Short press to check accumulated records in all operation periods, including

accumulated operation time, electricity consumption and electricity cost; press and hold

“MENU” button for 5~10 seconds, the ammeter steps into set mode, and “SET” cursor

flickers on the display. Three values can be preset: unit price for electricity, standby

power and alarm point of the ratio of operation condition. Press “UP” or “DOWN” button

to adjust the values, and press “MENU” again to confirm the preset value. If there’s no

operation on the buttons for some time, the ammeter will automatically exit set mode

and turn to normal measurement mode.
