User manual CONRAD ENERGY MONITOR 3000

[. . . ] In order to maintain this condition and ensure safe operation, you as the user have to observe this operating manual. - Monitoring of voltage, current and frequency - Display of active power, apparent power and cos phi - Min/max value recording of voltage, current, frequency, active power, apparent power and cos phi - Determination of "On" time for devices that run constantly (i. Refrigerator) - Display of used energy and accrued power costs - Cost forecast - Dual programmable power tariffs Before you connect the Energy Monitor 3000 to an outlet or power load, the desired power tariff must be set. If values fall below or exceed these limit values, exact measurements are no longer possible. [. . . ] The connected load may not exceed 3000W (13A). the recommended operating temperature is between +10 and +40°C. High temperatures, especially during measurement of large power loads, lead to danger of overheating and can thereby permanently destroy the Energy Monitor 3000. avoid operating under adverse environmental temperatures and near flammable gases , vapours and dust. For reasons of safety, never allow the device to be operated when wet or in a damp environment. When cleaning or servicing, the device must be disconnected from every source of operation voltage. Condensers in the device may still be charged, even if the device was disconnected from all voltage sources. In schools, training facilities, hobby and self-help workshops, qualified personnel must supervise the operation of measurement units. In commercial institutions, make sure you observe the accident prevention regulations of the commercial trade organization for electric installations. Do not insert needles, metals or any other objects into the device. Press and hold the "MIN/MAX CLR" button for longer than 4 seconds to set the "total energy costs", the "cost projection", "kWh", "rech" and "on h" to "0". With the "Tariff (Set)" button, you can switch between Tariff 1 and Tariff 2, display the "total accrued costs" for every tariff or change the displayed tariff. With the "Mode" button, increase the value of the blinking position from 0 to 9; reset to 0 with the "MIN/MAX CLR" button. After entering the desired values, you can select the next position with the "Forecast" button. After entering all values, confirm the adjusted tariff with the "Tarif (Set)" button. Change to the second tariff with the "Tariff (Set)" button and repeat the entry as in steps 3 to 5. By pressing the "MIN/MAX CLR" button for more than 4 seconds, you can set the data for "rec h" (recording time), "on h" ("on" time of connected power loads, e. The cost forecast calculates the projected energy costs from the momentary power recording of the connected power loads using the set energy tariff. By pressing the "Tariff (Set)" button, you can switch between displaying the costs forecasts based on Tariff 1 and Tariff 2. With the built-in battery, you can set saved data, recordings, and tariff setting even if the Energy Monitor 3000 is not connected to a power outlet. To save battery power, the LCD switches to sleep mode 60 seconds after the unit is disconnected from power outlet. To leave sleep mode, press the "Mode" button or plug the Energy Monitor 3000 into a powered outlet. [. . . ] The longer the Energy Monitor 3000 is connected, the more accurate is the cost forecast. The power supply on a power net is never constant and varies from place to place. For example, a voltage fluctuation of 1% per second for a calculated cost forecast over 5 minutes will never be as accurate as a cost forecast taken over 3 hours. Some devices use more current than others immediately after switching on. [. . . ]
