Operation
The operation of “The Substitutor” model RC167 involves substituting various electronic components. For carbon resistors, select the appropriate range (RX1 for 10 ohms to 5.6K ohms, RX1000 for 10K ohms to 5.6Meg ohms) using the slide switch. Choose the desired value on the rotary switch, ensuring to multiply by 1,000 for RX1000 range values. Disconnect power before substitution, connect the component using banana plug to alligator clip leads, and then reapply power.

Safety & Warnings
When testing electronic equipment, there is always a danger present. Unexpected high voltages can be present at unusual locations in defective equipment. The technician should become familiar with the device he is working on and observe the following precautions:
1. An isolation transformer should always be used on equipment having one side of the AC line tied to the chassis. If an isolation transformer is not used, a severe shock hazard can result if the chassis of the equipment being serviced is tied to the “hot” side of the AC line.
2. When making test lead connections to high voltage points, remove the power. If this cannot be done, be sure to avoid contact with other equipment or metal objects. Place one hand in your pocket as a safety precaution and stand on an insulated floor to reduce the possibility of shock.
3. Discharge filter capacitors before connecting test leads to them. Capacitors can store a charge that could be dangerous to the technician.
4. Be sure your equipment is in good order. Broken or frayed test leads can be extremely dangerous and can expose the technician to dangerous potentials.
5. Remove the test leads immediately after the test has been completed to reduce the possibility of shock.
6. Do not work alone when working on hazardous circuits. Always have another person close by in case of accident. Remember, even a minor shock can be the cause of a more serious accident, such as falling against the equipment, or coming in contact with higher voltages.
