Function Keys Description

1. The 

COST

 button cycles through each function in the upper display 

as indicated by "Total time", "Cost", "Set", "Energy" and "CO

2

".

2. The 

MODEL

 button, cycles through each function in the lower 

display as indicated by "Voltage" , "Current", "Power", "Power 

Factor" and "Freq".

3. The 

SET

 button allows you to configure the CO

2

 & KWh cost functions.

4. The 

+

 button has three main functions, the first is to increase the 

number of digits when configuring the CO

2

 & kWh costs at a 0-9 

cycle. The second is the reset function; reset the Energy, Cost or 

emission load of CO

2

 by holding it down. The 

+

 button is also used 

to power on the unit when power is off.

Operating Instructions

1.  Plug the power meter into a household receptacle and it will automatically start.
2.  Select the desired function by pressing the 

MODEL

 button.

3.  Return to the default function ("Voltage") by holding the 

MODEL

 button.

Note:

 If the unit has been in use for less than 1 day, only "Hour and Min" will 

be displayed as shown in Figure 1 below. Check elapsed time by pressing the 

+

 button as shown in Figure 2. If the time accumulated exceeds 1 day, it will be 

displayed in the form of "Day" as shown in Figure 3. To view the total accumu-

lated time, press the 

+

 button to display "Day" followed by "Hour and Min".

Setting the CO

2

 Cost Function

The production of energy releases greenhouse gases (among others carbon 

dioxide CO

2

), which places a burden on the environment. With this device, you 

are able to determine how much CO

2

 is released by an energy supplier with the 

measured kWh value. There are different CO

2

 equivalents depending on the 

type of energy. The CO

2

 equivalent indicates how much of a defined  

quantity of a greenhouse gas contributes to the greenhouse effect. Carbon 

dioxide serves as a comparison value.
The factor for the CO

2

 equivalents is entered in the device 

in kg/kWh and displayed accordingly in kg/kWh. You can 

find information on the CO

2

 equivalents to be entered on 

your power bill and on the internet, technical manuals or by 

contacting your energy supplier.
1.  To set your kg/kWh cost, switch to the "CO

2

" cost 

function by pressing the 

COST

 button.

2.  Once the CO

2

 parameter is visible press and hold the 

SET

 button.

3.  Adjust the values by pressing the 

+

 button.

4.  When the desired value has been set, save the data by 

holding the 

SET

 button.

Setting the kWh Cost Function

To accurately calculate the actual cost of electricity consumed and to project 

future costs, first you must set your local utility's electric rate into the unit. 

The rate is typically charged as dollars (or cents) per kilowatt-hour (KWH). You 

can find this rate on your last utility bill or you can contact your utility supplier 

directly to confirm your rate. 
1.  To set your kWh cost function, switch to "kWh" cost 

function by pressing the 

COST

 button. 

2.  Once the kWh parameter is visible press and hold the 

SET

 button.

3.  Adjust the rate values by pressing the 

+

 button.

Note:

 if your utility charge is 10.6 cents per KWH, set the 

rate to $0.106 on the LCD display.
4.  When the desired value has been set, save the data by 

holding the 

SET

 button.

Battery Replacement 

Please ensure the meter has been disconnected from 

power prior to replacing battery. Remove the battery cover 

with a screwdriver.
Once the cover has been removed, replace the battery cell 

and tighten the cover back on. See the following figure for 

detailed steps:
