+ | **Functions** \\ | ||
+ | Assign each input its function.\\ | ||
+ | \\ | ||
+ | If you assign input **Counter ** function, it will count pulses.\\ | ||
+ | <WRAP info> You can erase pulse score by changing energy correction, by changing input function (Reader, Inactive) or by pressing a reset button for 4 sec. The reset button is at the top of the box bellow Status diode. You can use e.g. a paper clip to press the button. </ | ||
+ | \\ | ||
+ | In case there is no device connected, choose **Inactive**.\\ | ||
+ | \\ | ||
+ | **Name** \\ | ||
+ | You can assign the input any name (e.g. electrometer, | ||
+ | \\ | ||
+ | **Meter Type** \\ | ||
+ | Select appropriate meter for measured value (power, gas, water).\\ | ||
+ | \\ | ||
+ | If you want to measure power, select reading energy production or consumption.\\ | ||
+ | \\ | ||
+ | **Number of Pulses per 1 (kWh, m³)** \\ | ||
+ | Fill in the number of pulses per a unit (kWh, m³), that your meter generates at the SO output. This information is stated at the meter' | ||

+ | It is essential that electro meter' | ||
+ | \\ | ||
+ | <WRAP info> Default setting is reading pulses from the electro meter, value 1000 pulses per 1 kWh. If your electro meter shows a different number, change the setting. </ | ||
+ | The number of impulses per 1 kWh is usually between 250-1000 imp/1kWh. In case there are 2 possible numbers of impulses at your electro meter, the lower number is usually the right one for the SO output.\\ | ||
+ | The higher number tells you how often a LED diode at your electro meter switches on. </ | ||
+ | **In case you need to setup number of pulses other than 1000 per 1 kWh než 1000, it is essential to differentiate between direct and indirect measurement: | ||
+ | ==== 1. Direct Measuring ==== | ||

+ | |||
+ | In the electro meter' | ||
+ | |||
+ | |||
+ | ==== 2. Indirect Measuring ==== | ||
+ | |||
+ | |||
+ | In the electro meter' | ||
+ | \\ | ||
+ | Example: Electro meter' | ||
+ | \\ | ||
+ | <WRAP half column> Look at the indirect power measuring transformer (1 transformer connected to each phase) and find a ratio (e.g. 150A/5A). Use the result of this ratio (30 in this example) in the formula (10 000/30). Fill in the whole formula (i.e. 10000/30) into box Number of Pulses per 1kWh.\\ | ||

+ | **Meter Correction ** \\ | ||
+ | This box is used for initial setting up SM2-RM and pulse meter. Fill in current value of kWh or m³ that your meter displays.\\ | ||

+ | **Nominal Capacity [kWp]** \\ | ||
+ | In case your device reads power produced in your PV plant, fill in the box Nominal Capacity.\\ | ||
