Use Cases

Match the tool to the test

Use digital multimeters for common voltage, current, resistance, continuity, diode, capacitance, or frequency checks, depending on the model. Choose calibrator meters for process-device calibration, thermocouple calibrators for thermocouple devices, and continuity testers for identifying wires or verifying long cable runs.

How to Choose

Compare measurement functions and operation

Review the functions required for your work, then compare auto-ranging and manual-ranging operation. Also consider display count, backlighting, data hold, non-contact voltage detection, listed voltage range, and stated measurement safety category where provided.

Applications

Support troubleshooting and maintenance

These tools are suited to circuit and component checks, outlet and GFCI testing, breaker identification, wire tracing, insulation evaluation, process-device calibration, and thermocouple testing. Compact and pocket-size options help users carry a meter between testing tasks.

Additional Information

Consider accessories and work convenience

Included leads, clips, cables, adapters, cases, lead storage, flashlights, and automatic power-off can affect day-to-day usability. Some calibration tools include universal 100V–240V AC adapters with four plugs and hard carrying cases.

Digital multimeters

Select the meter format and functions that fit routine testing

Digital multimeters in this category support a range of common electrical checks. Some models use auto-ranging operation to simplify setup, while manual-ranging models allow the user to select the appropriate range.

  • Available functions across represented meters include AC/DC voltage and current, resistance, capacitance, frequency, diode, and continuity checks.
  • Non-contact voltage detection is available on select compact, pocket, and manual-ranging meters.
  • Backlit displays, including 2,000-, 4,000-, and 6,000-count displays, can improve readability in lower-light areas.
  • Data hold, integrated lead storage, replaceable leads, rubber boots, flashlights, and automatic power-off are available on select models.
Specialized testing and calibration

Choose dedicated tools for calibration, insulation, or wire work

For applications beyond standard electrical measurement, the category includes instruments designed around specific diagnostic or calibration needs.

  • Current and voltage calibrator meters provide precision sources for calibrating process devices.
  • Thermocouple calibrators source and measure J, K, T, E, C, R, S, and N thermocouple devices and can display °C, °F, or mV.
  • A true RMS insulation tester and multimeter measures insulation resistance and supports PI and DAR testing.
  • Electrical troubleshooting kits can combine breaker finding, outlet and GFCI testing, continuity checking, wire tracing, and AC voltage detection.
  • Remote continuity testers support one-person wire identification and continuity checks across runs up to 10,000 ft.
Review ratings, ranges, and connectivity

Confirm the stated capabilities before choosing

Compare each tool’s listed electrical ratings and task-specific features against the work to be performed. Represented models include meters with a CAT III 600V rating, a CAT IV true RMS insulation tester and multimeter, and a manual-ranging meter with a 500V AC and 600V DC range.

  • One manual-ranging model measures resistance up to 2 megohms.
  • The CAT IV insulation tester and multimeter includes a wireless PC interface at 915 MHz.
  • Programmable timer and comparison mode are available for insulation measurements on one specialized model.
