Q1: What is an analog multimeter?
A1: An analog multimeter is a type of electrical measuring instrument that displays readings via a moving needle over a graduated scale. It is used to measure various electrical parameters such as voltage, current, and resistance in circuits, and it operates on the principle of a moving coil galvanometer.

Compared to digital multimeters, analog multimeters are valued for their ability to show continuous variations in readings, making them particularly useful for observing fluctuations in measurements. However, they are generally considered less accurate and harder to read due to the parallax error and the need for manual range selection.

Q2: How do I zero the analog multimeter for resistance measurements?
A2: To zero an analog multimeter for resistance measurements, first set the multimeter to the lowest resistance range. Touch the two probes together to create a short circuit. Adjust the zero-ohm calibration dial, usually located near the dial or on the side of the meter, until the needle points to zero on the resistance scale. This ensures accurate readings by accounting for any internal resistance in the probes and meter.

Q3: What should I do if the needle doesn't move when taking a measurement?
A3: If the needle doesn't move, check the following:

• Connections: Ensure the probes are securely connected to the multimeter and making good contact with the test points.
• Range Setting: Verify that the range setting is appropriate for the expected measurement. If the range is too high, the needle might not deflect enough to be noticeable.
• Multimeter Functionality: Test the multimeter with a known voltage or resistance to confirm it is functioning correctly. If it still doesn’t move, the meter or the probes may be faulty and need repair or replacement.

Tips: How to use a SISCO analog multimeter to measure decibels?

Measuring decibels with an analog multimeter is similar to measuring AC voltage, except you use the "dB" scale (i.e., scale "E") when reading the values.

For measurements in the AC 10V range, directly read the value from the "dB" scale. If the reading exceeds +22dB, switch to the 25V, 100V, or 1000V range, and then add a certain value to the reading from the "dB" scale according to the instructions below. The resulting value is the final measurement result.
