A digital multimeter can be used to measure DC and AC voltage, DC and AC current, resistance, capacitance, frequency, batteries, diodes, and more. The overall circuit design is centered around a large-scale integrated dual-slope A/D converter, equipped with full-process overload protection circuits, making it a high-performance tool and an essential instrument for electricians. 1. Precautions … Read more
Search on WeChat Technical Training 1. Correct Usage of Multimeter To use a multimeter correctly, familiarize yourself with the dial. Adjust the two zero position knobs gently. Choose the correct terminals, and insert the red and black probes into the appropriate holes. Rotate the switch to the correct gear, and ensure the range is selected … Read more
Previously, we discussed common analog and digital electronics used by electronic engineers, which received a lot of attention from our fans. Today, we will mainly talk about the measurement instruments commonly used by electronic engineers, hoping to help our friends. Let’s take a look together! 1. Multimeter A multimeter is one of the most basic … Read more
For different channel input signals, sometimes we want one channel signal to meet one condition while another channel waveform meets a different condition, achieving a logical “AND” combination for the channels. For example, how can we trigger channel 1 on a high level while triggering channel 2 on a rising edge? The ZDS2022 oscilloscope not … Read more
Hello everyone, in this video we will introduce the most commonly used Lissajous measurement method in X-Y mode. First, we will connect two sine wave signals with the same frequency but different phases to Channel 1 and Channel 2. After capturing the waveform, you can see that the phase difference between the two signals is … Read more

When testing a signal with an output impedance of 50Ω using a Pico oscilloscope, a 50Ω to 1MΩ direct terminal is required. Recently, during an on-site test with a client, I found that the waveform oscillated severely, as shown in Figure 1 (red box), making it impossible to conduct accurate data analysis. Figure 1 Severe … Read more
Hello everyone, in the previous episode of our 100-episode practical video series, we shared the pulse width search function of the ZDS2022 oscilloscope. The oscilloscope’s search function is practical and convenient. However, some users are still not very familiar with the search function of the ZDS2022 oscilloscope. In fact, the ZDS2022 oscilloscope has a powerful … Read more
During the technical exchange meetings of oscilloscopes, we learned that some customers need to understand the rise slope of CAN signals. They usually measure some values and then calculate manually. The ZDS2022 oscilloscope will save you a lot of time by displaying the results directly without manual calculations! The operation is very simple. First, connect … Read more
