The output range of the signal generator determines the maximum current it can produce. It is important to choose a device with a wide output range (0-22 mA or higher) to cover various instrument ranges.

Power Source

Consider the type of power source required by the signal generator. Some devices can be powered by batteries, while others need an external power supply. Choose one that fits your needs.

User Interface

The user interface should be user-friendly and easy to navigate. Look for devices with LCD screens, push buttons, and rotary knobs for easy operation.

Types of Signal Generators

There are two main types of signal generators: handheld/portable and benchtop models.

Handheld/Portable Models

These are compact, battery-powered devices that are suitable for on-site calibration tasks. They are lightweight and easy to carry around, making them ideal for field technicians.

Benchtop Models

These are larger, more powerful devices designed for laboratory use. They offer advanced features such as higher accuracy and resolution, multiple output channels, and computer connectivity.

Budget Considerations

The price of a 4 20 Ma signal generator varies depending on its features and specifications. It is essential to determine your budget beforehand so that you can narrow down your options accordingly.

However, I recommend investing in a good quality device with advanced features if you use it frequently for critical applications.
