https://sites.google.com/site/ema1powermeter/ema1type1-type2-differences You have the type 1 and type 2 incorrectly written up initially - type two uses 3x1.5v as per the rest of your documentation right? Easiest way to determine which meter from the label: 'type 2' has label text: "Battery 2X1.5V" 'type 1' has label text: "Battery 3X1.5V" In the picture below the Type 2 is shown first (on the left)..

Yes that is correct! - thanks for pointing that out Dafydd. I have updated it with the correct text.

Also would like to verify that the newer 3x1.5V model gives substantially different (more accurate) results especially low power states. Example: 24" LCD standby type 1 meter: 9watt 24" LCD standby type 1 meter: 0.5watt Desktop PC full-load type 1 meter: 85watt? keeps cycling values Desktop PC under full-load type 2 meter: 175watt (X3 720BE ati5750 gfx) The older model isn't really worth bothering with IMO

04/05/2012 14:35 Ema1 [Moderator]Hi Ron, this is the second request I've had to send instructions through email. I'm not sure I understand. You can use the links above to view each guide. Can you see the links ok in the table near the top of the page?
20/05/2012 22:56 Ian melborneHas anyone fully decoded how Price 1 and 2 work? It is easy to set price, the day(s) and a period of time, but despite a lot of experimenting I cannot work out how the two prices interact, or whether one has priority, or frankly, what it all means. Answers anyone?
21/05/2012 07:45 Editor [Moderator]Hi Ian, what is it exactly that you wish to achieve with the price settings? What is the exact pricing/time scenario you are trying to set it up for?
14/05/2013 15:35 andy Thanks for this guide, like others I had lost my incomprehensible instructions.

I'm confused about the on time display. I forgot to check once I had plugged the unit in and its been a little while. The time on says 2 08 51. Now I know the 51 is minutes but is the 2 weeks and the 8 days or hours? Seems like more likely to be hours for the 8.
