 +===== Inputs and Measurement =====
 +
 +
 +----
 +
 +
 +In SM2-RM go to menu System Setup/Inputs and Measurement.\\ 
 +\\ 
 +{{  :en:sim:rm:web_zarizeni:vstupy_a_mereni_3citace.png?nolink&  }}\\ 
 +==== Input 1, Input 2, Input 3 ====
 +
 +
 +**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. </WRAP> If you choose **Input** function, there will be value 1 or 2 (connected, disconnected) in "Overview".\\ 
 +\\ 
 +In case there is no device connected, choose **Inactive**.\\ 
 +\\ 
 +**Name** \\ 
 +You can assign the input any name (e.g. electrometer, gas meter, door sensor…).\\ 
 +\\ 
 +**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's label or in its documentation. If wrong number of pulses is entered, SM2-RM will show wrong production or consumption values.\\ 
 +\\ 
 +It is essential that electro meter's pulse output is configured for delivery.\\ 
 +\\ 
 +<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. </WRAP> <WRAP half column>\\ 
 +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. </WRAP> <WRAP half column> {{  :en:sim:rm:rychly_navod:jak_na_to:obrazek_elmeru.png?100  }}</WRAP>\\ 
 +**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's label or documentation find out how many pulses per 1 kWh your electro meter generates at the SO output. Fill in this value into relevant box in SM2-RM menu.
 +
 +
 +==== 2. Indirect Measuring ====
 +
 +
 +In the electro meter's label or documentation find out how many pulses per 1 kWh your electro meter generates at the SO output. Use this number in calculation, see example bellow.\\ 
 +\\ 
 +Example: Electro meter's label states 10 000 impulses per 1 kWh.\\ 
 +\\ 
 +<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.\\
