Fast guide

The guide on this page gives three different fast options for using your meter without changing any settings.
For more detailed instructions choose the user friendly guide or quick guide.

Before you start:

Get the 'unit cost' from your electricity bill. This cost per unit is the cost per kwh. If you don't know what your cost is use 30 cents (00.30) per kwh-unit as a rough guide.

Option 1 - instant results!

Find out how much power your appliance is using right now - and estimate how much it will cost to run for a day. 

  1. Plug the meter in.
  2. Plug the appliance into the meter.
  3. Begin using the appliance. 
  4. Press the FUNC button on the meter until the WATT symbol appears in the display. This is the number of watts your appliance is using at the moment.
  5. If you want to estimate how much this appliance would cost to run for a whole day, use this simple calculation:
450 [Watts] x 0.001 [Watts to KwH conversion factor] x $0.30 [cost in cents per unit KwH] = $0.13 [= 13 cents per hour to run this appliance]

Use your own values for [Watts] and [cost in cents per unit KwH]. Do not change the Watts to KwH conversion factor. The conversion factor stays the same.

Option 2 - results in 24 hours!

Find out exactly how much power your appliance uses in a 24 hour period - and calculate the cost exactly.

  1. Plug the meter in.
  2. Plug the appliance into the meter.
  3. Use the appliance for 24 hours before going to step 4.
  4. Press the FUNC button on the meter until the Kwh symbol appears in the display. The number on the display is the number of Kwh units your appliance used during the last 24 hours.
  5. To work out the cost per day multiply this Kwh number by your unit cost like this: 1.5 [Kwh] x $0.30 [cents per unit] = $0.45 [cents a day to run this appliance]. Just put in your own values for [Kwh] and [cents per unit].
  6. Now you can estimate the cost per month using this example: $0.45 [cost per day to run this appliance from above] x 30 [days (approximate) in a month] = $13.50 per month to run this appliance.
  7. Reset the KwH counter before measuring the next appliance. To reset the counter press FUNC until the Kwh symbol appears in the display then press and hold the FUNC button until the counter is reset to zero. 'Type 1' - press and hold FUNC for five seconds or until clear.

Note: Users of meters with CO2 functions report the FUNC button does not clear recorded data in the CO2 and Kwh categories. Please comment below if you have a solution for this. Please comment below with your model number if your meter has this problem.

Option 3 - results in 30 days!

Monitor an appliance for a month - in many cases this will give the most accurate results.

  1. Plug the meter in
  2. Plug the appliance into the meter
  3. Use the appliance for a month before going to step 4
  4. Press the FUNC button on the meter until the Kwh symbol appears in the display. The number on the display is the number of Kwh units your appliance used during the last month
  5. To get the cost for this month multiply the number of Kwh the appliance used by your cost per unit: 45 [Kwh] x $0.30 [cents per unit] = $13.50 [per month to run this appliance]
  6. After using this method remember to reset the KwH counter before measuring the next appliance. To reset the counter press FUNC until the Kwh symbol appears in the display then press and hold the FUNC button until the counter is reset to zero. 'Type 1' - press and hold FUNC for five seconds or until clear.

Note: Users of meters with CO2 functions report the FUNC button does not clear recorded data in the CO2 and Kwh categories. Please comment below if you have a solution for this. Please comment below with your model number if your meter has this problem.

Option 4 - calculate total cost automatically!

This is not so quick because you will need to enter the Kwh cost into the meter. It is easy to do. Use the quick guide.

15/02/2011 16:47JimI'd just like to say thanks for the instructions. My first reaction to reading the manual was "Oh S**t " but, you have simplified it perfectly. All I wanted to do was to get a
rough idea on each appliance. Again thanks.
21/06/2012 12:09WilliamThere's a tiny reset button next to the UP button on mine, which resets the whole thing (including the time). I don't know if there's a better way to reset the Kwh record alone though.
21/06/2012 20:53Editor [Moderator]Option 2 - Step 7 tells you how to do that. For more detailed information see the links to the other guides in the first paragraph of this page.
05/03/2013 23:13EddieI can't imagine why the designers included a clock function but omitted an elapsed time function. Without this the clock seems to serve no purpose.  Is this hidden somewhere?  I have to make a written record of when I first plugged a N67HH device in in order to get a kWh per day calculation, when it could do this so easily within the device.  Any ideas?
 18/06/2015 18:12John from OzMy largest electricity user is the Refrigerator/Freezer.

As this is essentially an air conditioner to cool down the contents - it cycles on & off.  Further complicated by cyclic defrosting; & how often the fridge doors are opened, & for how long, to allow already cooled air to escape. 

I might suggest averaging results over a full week - noting that the fridge will have to work harder (& co$t more to run) in the summer heat to cool the contents. For the frugal you might like to adjust the fridge cooling settings [using a fridge thermometer] between seasons ;-) 

Cheers to my Kiwi neighbours!
