IEC 1010-2-032, 600V CAT III

The 337 Clamp Meter features:

  • Three year warranty
  • True-rms clamp meter
  • MIN/MAX capability
  • Extra large jaw
  • Measures ac/dc amps, ac/dc volts, ohms and motor start-up current
  • Large, backlit display is easy-to-see in less than ideal conditions
  • In-rush current function for measuring starting current for motors, lighting, etc.
  • Fits perfectly in your hand and into tight places
  • Handy ‘Display Hold’ button keeps measurements on the display
  • Meter controls are positioned so current measurements can be done with one hand (index finger on clamp opening lever and thumb on rotary switch)
  • Auto shut-off maximizes battery life so the meter works when you need it
  • Improved low current measurement accuracy for new microprocessor technology

Safety conformance
IEC 1010-2-032, 600V CAT III
