Below is the text from the original instruction manual provided with an Elto EMA-1 'type 1' power usage meter purchased in New Zealand, May 2010. The original instructions below do not contain the following information:

• To reduce frustration plug the device in when setting up for the first time (this strategy avoids the display standby mode)
• The effects and operation of user defined maximum load level.
  
• How to return to data viewing mode after setting kWh cost.

For further details please see the updated user guide. For a really fast start try the quick guide or the fast guide.

Note: Instructions provided are for the model sold in New Zealand. Models sold in other markets may differ in specification. For example, models sold in New Zealand are rated for a 10 amp maximum. Models sold in the UK market are likely to be rated at 13 amps because the UK standard power socket has a design history which requires it to handle much higher power levels than a NZ standard power socket.
