Reading a Digital Multimeter?

Posted at: 2015-01-07 
At 200mA range setting, whatever it display is in mA. Suppose it shows 0.1mA ,means 100uA.

At 200A range setting, whatever it display is in A. Suppose it show 0.1A, means 100mA.

9V battery would not give out more than 1A.

perhaps 200A should read as 200uA?? Normally the meters have a max of 10 amp range!! the reading of 50.0 in 200uA range will mean 50.0uA. The reading of 5.0 in 200mA range will mean 5.0mA.

The 200A will be the 200 amp range and the 200m will be milliamp range. That will be the maximums on those ranges.

The range scale should be shown on the meter.

My grand daughter is doing a science project and it involves using a digital multimeter, she had it hooked up to a 9V battery and was putting the sensor in different liquids, she would have to turn the multimeter to one setting 200m for certain liquids and set it to 200A for other liquids. how do you know if the print out is in microamps or milliamps she recorded the data but does not know if it is micro or milli amps? She can do the calculations to convert from micro and milli into amps but please , how to determine if the print out is microamps or milliamps? AND THANK YOU SO MUCH FOR YOUR HELP..
