Which version should you buy?

This page covers: Klein Tools CL710 clamp meter.

  • CL710 clamp meter

    This page

    Model: CL710

    What differs
    AC/DC clamp meter with LoZ, voltage detection and a lit dial. Its specifications and manual provide no temperature, DC microamp or worklight function.
    Best for
    General electrical work needing AC/DC clamp measurements and LoZ.

  • CL810 with worklight

    Model: CL810

    What differs
    Adds a worklight, DC microamp readings, temperature via thermocouple and inrush measurement.
    Best for
    HVAC and motor troubleshooting needing those extra measurements or light at the work area.

Watch out

  • Both are AC/DC clamp meters; check CL710 versus CL810 rather than relying on the current rating.
  • The CL710’s illuminated dial is not the CL810’s worklight.
  • Do not infer a CL710 temperature function from a thermocouple mentioned in a listing or feature bullet.

Why people pick it

  • Measures DC current as well as AC, which car, solar and battery work needs
  • CAT IV 600V and CAT III 1000V rating
  • LoZ mode to rule out ghost voltage, plus non-contact detection in the jaw
  • 6,000-count display that stays readable in sunlight, per Klein

Know before you buy

  • No DC microamp range, so it can't read HVAC flame-sensor current
  • The lowest current range is 60 A (10 mA steps), so very small loads read coarsely
  • No temperature function in the manual
  • Jaw opens to 1.4 in, smaller than the CL390's 1.6 in
