Selection of suitable accessories for digital multimeter
Digital multimeter can use many accessories. Accessories can expand the range of the digital multimeter, while making the measurement easier. High-voltage probe and high-current probe will be very high voltage, current down to the degree that the digital multimeter can be measured. Temperature probes transform your digital multi-meter into a handy digital thermometer. High frequency probes measure voltages at very high frequencies.
In addition, optional test cables, probes, and test clips help you easily connect your digital multi-meter to your test circuit. Soft and hard cases not only protect the multimeter but also make it easy for you to store accessories and the multimeter in them. Using a good multimeter test accessory can avoid the problems caused by test cables and
The use of a good multimeter test accessory can avoid measurement errors caused by the connection between the test leads and the digital multimeter.
Some digital multimeters also have universal interfaces (e.g. OI857 or OI859CF), which can be used as a computer to communicate and analyse data, or as a continuous voltage or current collector, greatly enhancing the performance of the digital multimeter.
Easier Simple Measurement
Often you have to devote both hands and eyes to board inspection: watching the multimeter display can cause probe slippage. Some multimeters offer a lockout feature that locks in a valid reading, allowing you to focus on probing.
High voltage and high current probing
The High Voltage Probe allows you to measure high voltage and high current with a multimeter. It has a fixed input impedance mode (the product shown has an input resistance of 10MΩ and a 1000:1 voltage divider, extending the measurement capability of the voltmeter to 40KVDC)
