1) Get a multi-meter and set it to measure DC current. I borrowed this Fluke multi-meter from work. I have to set the dial to measure DC current and I have to attach the red probe to the port that measures current. (Picture #1)

2) Start with a fully charged battery hooked up the Accu-Cycle. My Tx battery is connected here. Red lead to the red port. Black lead to the black port. (Picture #1)

3) Now connect the multi-meter in series. Do do this, disconnect the black lead and put the red probe into the black port instead. Now connect the black lead to the black probe. I just held them together. The multi-meter is now connected in series. Remember these connections, you are going to have to hold it like this when the Accu-Cycle is open and the ports are up-side-down and facing away from you. (Picture #2)

4) Set the discharge rate to 250 mA and start discharging the battery. The actual discharge rate will show up on the multi-meter. I was reading 257.2 mA. (Picture #2)


5) Open up the Accu-Cycle. The picture shows where the Tx and Rx potentiometers are. (Picture #3)


6) Adjust the Tx pot so that you bring the current back down to 250 mA. You are going to have to hold the multi-meter in series and start the discharge cycle before you do this. (Picture #4)
