Now that you have completed the lab, let's see how well you can read the following instuments. First identify the precision of the instrument, then read it as accurately and precisely as possible. Type the numbers only. Include both the precision of the instrument and the measurement.

Format: precison, measurement

So if your precision is 0.001 and your measurement is 12.0239, your answer would be "0.001, 12.0239" Be sure to include the zero in front of the decimal for numbers less than one and put a space after the comma.
