Problem Statement

 * Solder the voltmeter resistor off, then solder a 1 k resistor on.
 * Test the converted ammeter in circuit.
 * Figure out meter overload problem.
 * Figure out the correct measurement of meter.

Work flow

 * Solder the voltmeter's resistor off.Voltmeter's resistor off.JPG
 * Solder 1k resistor on.1k resistor on.JPG
 * Assemble the converted ammeter in one piece. Converted ammeter.JPG
 * Testing the converted ammeter in circuit.Testing converted ammeter.JPG
 * The needle flip over to another side.
 * In order to slove the overload problem, replace a bigger resistor(10k). Test again.
 * The needle go to the middle of meter. The measurement is not correct.
 * In order to solve the overload problem, try to replace the small voltmeter with bigger voltmeter(1000v).1000v voltmeter.JPG
 * Take out the inner part, can't find where the resistor is.Inner part.JPG

Algorithms (data structures, control flow, data flow)
R=V/I

Next Steps

 * Find out 1000v voltmeter's structure and diagram.
 * Figure out the measurement of converted ammeter.
 * Follow Conversion of voltmeter to ammeter to test ammeter again next week.

Next Steps

 * Try to replace shunt resistor(1ohm) with voltmeter's resistor in same place.
 * Figure out where to put Ammeter in power supply.
