Digital Power Meter Model 4-1850DR
The BRAND ELECTRONICS Power Meter is designed to provide you with accurate information
about how much electricity an electrical device uses.
The Power Meter has the following displays:
1) "0000W 0.000kWhr (or 0000 kWhr)". This displays the amount of power being used right
now (Watts) and the amount of power which has been used (kilo-Watt hours). Your power
company charges you by the kilo-Watt hour. This reading is displayed after the unit is reset or first
plugged in (after the calibration cycle).
2) "0000.0 Total hrs". This displays the amount of time since the Power Meter was last reset.
3) "$000.00 @10c/kWhr". This displays the cost of running the device since the Power Meter
was last reset.
4) "$000.00 av/month". This displays the estimated cost of running the device for one month.
5) "10.0 cents/kWhr". This displays the cost per kilo-Watt hour of electricity. 10c is the default
value. This value can be changed as described below.
Use of your Power Meter is very simple:
1) Plug the Power Meter into an electrical outlet within reach of the appliance you wish to

Rev 0 2
measure. The Power Meter automatically turns on and will display "BRAND ELECTRONIX"
briefly. The Power Meter will then display "0000 W 0000.0 kWhr" (if something is already
plugged in and drawing power, the display may not be zero).
2) Plug your appliance into the receptacle on the Power Meter.
3) Turn on the appliance (if necessary).
NOTE
Plugging in a device before plugging in the Power Meter is ok, even if the device is "on",
4) The number displayed on the Power Meter is the power being used by the appliance in "Watts".
For example, if you plugged in a lamp with a 100 Watt bulb, the Power Meter would read
approximately "100".
5) The "kWhr" value will change depending upon the power being used. For example, if you plug
in a 100 Watt lightbulb, the value would be approximately "0.100 kWhr" after 1 hour.
6) To find the cost of running a device, depress the ">" button until the display reads ""$000.00
@10c/kWhr". Now depress the "ENTER" button. The Power Meter display will show "10.0
cents/kWhr" (10 cents is the default value). Depress the "<" or ">" buttons to decrease or
increase the value to the desired amount. Pushing the "<" or ">" button once will decrease or
increase the value by .1 cent; keeping either button depressed will continuously decrease or
increase the value. When you have entered the desired value, simply depress the "ENTER" button
again, and the Power Meter will begin to display the cost. To see the "W kWhr" display again
simply depress the "<" or ">" arrow button. Doing so will not reset any values. You may switch
back and forth between the displays at any time.
7) To see the estimated cost of running the device for one month (the usual amount of time for your
electrical bill), depress the "<" or ">" buttons until the display reads "$000.00 av/month". The
actual value displayed will depend upon the cost per kilo-Watt hour entered, and the amount of
electricity used by the device since the Power Meter was last reset. This display is very useful to
find the cost of running devices which cycle on and off (like refrigerators, freezers, air
conditioner, etc).
8) To Reset the Power Meter at any time, simply depress the "RESET" button (Note, some meters
will require the ENTER button to be held while the RESET button is pressed). This will clear the
display, and reset all values, and the Power Meter will perform a self-calibration.

MEMORY
Your Power Meter is equipped with non-volatile memory for the following information:
kWhr
Cost per kWhr
Total cost
Total Time
These values are updated approximately every 8 minutes (the display will momentarily show ADATA SAVE@when this happens).
If the Meter losses power, the last saved data is used when the Meter is restarted.
To CLEAR the MEMORY, push the RESET button.
