Measuring instruments

Choose a measuring instrument according to whether you need a portable check or permanent measurement in a system. The function required, connection and reading method determine which group to consider.

Two different starting points

For handheld checking and measuring tools, explore multimeters, testers and voltage testers. Compare the exact functions, accessories required and selected model's application. For energy measurement and metering, continue to electricity meters and energy meters. Selection there follows the planned measurement system and method of obtaining data. Do not merge the two tasks solely because products contain a similar number or general measurement name.

Prepare requirements before choosing the model

Record the quantities to measure, required ranges and use conditions. For a portable instrument, confirm stated functions and matching probes or other accessories. For permanent measurement, establish phases, direct or indirect connection and required additional components. Product titles can help initial distinctions. However, check exact parameters and task suitability by reference and documentation without transferring data from another instrument in the same group.

Main appliance and system parts

The range also includes current transformers and other additional products. Check exactly what you are ordering and its intended model. Consider the main measuring instrument and necessary accessories together but with separate codes. When replacing one part only, identify remaining components before choosing the new one. Similar size or a general interface designation does not replace checking the specific combination.

Readings and mounting

Clarify how the result will be used: local display, data transmission or another intended function. Check the necessary interface and configuration for the exact model. A family capability does not automatically mean the function is available in every version. Where readings have special use requirements, establish suitability separately. Also check mounting format, required space and included equipment without inferring contents from a general system photograph.

The products presented from TESTBOY, LEGRAND and SCHNEIDER ELECTRIC can be viewed by code after this selection. The general tools and measurement section is a starting point for the rest of the work equipment. The final list must contain the exact instrument, application and all accessories required for the corresponding task.
