Gardner Bender digital multimeters are a reliable, portable solution for measuring voltage, current, resistance, and continuity in electronic circuits. Battery powered and equipped with clear LCD readouts, these instruments are ideal for technicians and hobbyists alike. To get the most accurate results, always refer to the device’s troubleshooting manual or schematic diagram before testing.
Examine the schematic to determine the expected voltage (DC or AC), resistance, and current at the test point. Knowing these values beforehand helps you select the proper range on the multimeter.
Rotate the selector knob to the desired voltage range. DC ranges are on the left; AC ranges are on the right. If you expect 20–200 V, set the indicator to 200 V. For values below 20 V, select 20 V. Touch the black probe to one side of the component and the red probe to the other, then read the LCD.
Move the selector to the resistance section (omega symbol). For a component expected to be 20–200 kΩ, set the dial to 200 kΩ for maximum accuracy. Place the probes on either side of the component and read the value on the display.
Set the dial to the 10 A section (white background). Ensure the red probe is connected to the 10 A jack. Probe both sides of the circuit element and read the current on the LCD.
If your model includes an audible continuity test, rotate the dial to the sound‑wave icon. A beep confirms a continuous path; silence indicates a break.
Keep the selector set to OFF when not in use to extend battery life.
Never use a DC voltage setting to measure AC voltage, such as from a standard home outlet. Doing so can damage the meter’s internal circuitry. Always use the designated AC range for AC measurements.
