Measuring Voltage
One of the most common uses of the Radio Shack 22-163 is to measure voltage. The manual outlines the procedure as follows:
Measuring DC Voltage
1. Set the function selector to the DC voltage (V—) setting.
2. Insert the red test lead into the VΩmA terminal and the black lead into the COM terminal.
3. Connect the leads to the circuit or component you wish to test, ensuring correct polarity.
4. Read the voltage on the display.
Measuring AC Voltage
1. Set the function selector to the AC voltage (V~) setting.
2. Use the same lead configuration as for DC voltage.
3. Connect the leads to the circuit and observe the reading.
Measuring Current
The Radio Shack 22-163 can also measure current, both AC and DC. The process varies slightly depending on the type of current being measured.
Measuring DC Current
1. Turn the selector to the DC current (A—) setting.
2. Change the lead configuration if the current exceeds 200mA; use the 10A terminal for higher currents.
3. Connect the multimeter in series with the circuit.
4. Read the current value displayed.
Measuring AC Current
1. Set the function selector to the AC current (A~) setting.
2. Connect the leads in series with the circuit, ensuring correct placement.
3. Read the resulting current on the display.
Measuring Resistance
Resistance measurements are crucial for diagnosing circuit components. Here’s how to perform this function:
Steps to Measure Resistance
1. Set the function selector to the resistance (Ω) setting.
2. Connect the red lead to the VΩmA terminal and the black lead to the COM terminal.
3. Touch the leads to the component or circuit to be tested.
4. Observe the resistance value on the display.
Safety Precautions
Using a multimeter involves certain risks, particularly when measuring voltage or current. The Radio Shack 22-163 manual emphasizes several safety guidelines:
1. Never measure resistance on a live circuit: This can damage the multimeter and pose safety risks.
2. Use the correct range: Select an appropriate range to avoid overloading the device.
