[. . . ] 9. 0 INTENDED USE: The measuring range of the Cost Control is from approximately 4W to 3600W (automatically varies from one appliance to another) and is therefore ideal for use with a large variety of electrical appliances. Cost Control is designed for use only as an indicator for the average cost and average amount of electricity used for electrical appliances. Despite its accuracy it is not officially certified and therefore readings cannot be used as evidence in any dispute between the Electricity Company and the user. · · Cost Control is approved for use on a 230V / 50Hz mains supply only. [. . . ] To do this, simply press and hold down the "COST" key (for approximately 4 seconds) and all values with the exception of Tariff (cost per kilowatt hour) will be reset to zero. Once all the values displayed are set zero in the "TOTAL COST" display, then press the "TARIFF" key to enter the Tariff setting mode. 12. 0 TARIFF SETTING MODE: The value of a single unit of kWh (kilo Watt hour) can usually be found on a previous electricity bill. Please take this figure from a recent bill as costs may have since been updated by the Electricity Company. If the cost of a kWh cannot be found on the bill, then contact your local Electricity Company for the price of this unit. The Tariff display may not necessarily be set to zero (as illustrated above). If there are any preset values that the user has not set themselves, then simply overwrite them when setting the unit cost of a kWh as follows: 1. Press and hold the "TARIFF" key (approximately 3 seconds) until the first digit on the right hand side starts flashing. Now press either the "POWER" or "COST" keys to set the desired digit. Each press of either key changes the digits by one. The "POWER" key increases the digits from 0 to 9 and the "COST" key decreases from 9 to 0. Once a digit is set, press the "TARIFF" key once to move to the next digit. until the desired values for the kWh are set. If any of the digits do not require changing then simply press the "TARIFF" key to move to the next. Once all the desired value has been selected, the "TARIFF" key should be pressed once more to confirm the setting of all digits (the last digit on the left had side will stop flashing). Once the Tariff is set, plug the Cost Control into the mains supply and then plug the electrical appliance into the Cost Control. 5. Note: The appliance should be operated as normal - for hints on this see the "Extra Notes" section. 13. 0 USING THE COST CONTROL Using the Cost Control is very easy. For example: the cost to operate appliance "X" is 7. 00 (, $, . . . etc. ) per day and after 20 days of operating the appliance, the TOTAL COST is 140. 00 (, $, . . . etc. ) therefore, we can assume the following readings: a) Cost per day is: b) Cost per month is: c) Cost per year is d) Total Cost is: When the monitoring of an electrical appliance is complete; simply turn the appliance off; remove the Cost Control from the mains and then remove the appliance from the Cost Control. However, should further monitoring be required, then do not remove the electrical appliance from the Cost Control and mains supply but simply take the reading with the electrical appliance still plugged in. Notes: The above illustrations shown assume a daily value of 7. 00 (, $, . . . etc. ) and 7 days per week, 30 days a month and 12 months a year (to alternate between these displays simply press the "COST" key. [. . . ] etc. ) but now the cost per day would have dropped to about 2. 00 (, $, . . . etc. ) as it has not been used for the last 23 hours. Before the lamp is turned "ON" on day 3, the Cost Control will have taken the total power consumption and the length of time that it has been turned off and averaged them out for an accurate cost per day reading. etc. ) and so you know how much, on average, the lamp is costing to operate everyday.
