Thank you very much. As I had few limitations (on using few products), I changed my idea towards generating power from Mud. I would appreciate if somebody could help me in using a Digital Multimeter. My Multimer (Commercial Electric - MAS830B -Green color) has
DC Voltage range (200mV,2V,20V,200V,600V)
DC Current range(20µA,200µA,2mA,20mA,200mA,10A)
AC Voltage range(200V,600V)
I am right now getting a good range of reading when I place Multimeter at the DC Current range(20mA). I want to know if I am correct. Can you help please..
1. Where do I need to place the rotary switch to select the correct range to be measured?
2. Some reading starts in a value and keeps decreasing. What should I do in this case. Do I need to have the start reading or the ending reading?
3. What is the ideal time to hold the test leads for each test?
4. When do I know the values are ready to add salt to test for the power?
I am doing this test with five different resistors
