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:
