In this tutorial we will show you how to modify your MultiMeter so that you may test both voltage and current drain quickly and easily. This entails installing Pro Plugs in line with the test leads and then building a series harness for testing current load. If this seems to complicated, or you just prefer to not do it yourself, we sell the Mini-Meter Pro which is already converted as shown here.

Amperage Harness

Cut the SuperFlex wire into 3 even pieces each 4 inches long. (2 black, 1 Red)

Strip and tin both ends of the 3 wires back 4mm Tin 3 pro plugs

Solder 1 black wire and 1 red wire to a pro plug. Make it so that the red wire is soldered to the female end of the plug. Black should be soldered to the Male end.

Place 2 pieces of heat shrink on each wire. Solder a second pro plug to the remaining end of the red wire. This time the red wire should connect to the positive end of the pro plug.

Now solder a third pro plug to the remaining end of the black wire. This time the black wire should connect to the negative end of the pro plug.

Place 2 pieces of shrink on the 3rd wire.

All that’s left is to solder the 3rd wire to the 2 remaining ends of the pro plugs. Note: if done correctly one end of the wire should solder to a negative end of a pro plug and the other end to a positive end.

Test Leads

Take the test leads that came with your meter and cut them approximately 5 inches from the connectors that plug into the meter.

Strip and tin the ends of the exposed wires.

Place 1 piece of heat shrink on each of your 4 wires. Solder a pro plug to the connector leads. Note: you want the red wire to be soldered to the male end of the plug.

Now Solder a pro plug to the test leads. This time you will want the black wire to be soldered to the male end of the pro plug.
