■ Easy to see, even when held down low Flip-type clamp on design delivers the ease-of-use demanded by fi eld technicians Flip-down display keeps readings in easy view whether the target wire is up high or down low Equipped with an innovative display that flips down for easy visibility, the 3291 and 3293 are designed for efficient measurement of indoor wiring in a variety of environments, from factories, buildings, and offi ces to residences. ■ Easy measurement of wires on ceilings ■ Easy to see, even when held up high Unmatched ease of use ❏ Clamp meter turns on automatically when the clamp is opened so you can begin taking measurement immediately. Flip angle: 180° ❏ Slim core opens wide for easier clamping. Open Jaws to Power On ❏ Backlight lets you read measurements in dim locations Up to 24 mm in diameter 3293 11mm Up to 30 mm in diameter 3291 8mm

  • Push and hold for 2 seconds to activate
  • Backlight goes out automatically after 15 seconds Sometimes it’s easier to clamp the target wire at an angle. New clamp design is easier to attach Slim clamp with a wide aperture attaches easily, requiring only 12.5 mm of space between wires. Display can also be reversed manually with the press of a button. ❏ Measurement reading reverses automatically when the display is fl ipped open to ensure readability. Easy to read means easy to use ❏ Display rotates freely through 18 0° to keep measurements in view. Automatically turns off 1 minute after input falls to 0A following measurement. (Can be manually disabled.)

❏ Easy-to-use auto range feature ❏ Get the maximum value of fl uctuating current readings Filter out noise The 3291 and 3293 incorporate a switchable high-frequency noise fi lter. When activated, this fi lter rejects frequencies of

180 Hz and above to enable measurement approximating the

fi lter characteristics of an earth leakage circuit breaker (ELCB). Filter on Extensive current measurement functions Use with 3-phase 4-wire 440V lines 3291: CAT III 600 V (CAT IV 300 V) 3293: CAT III 300 V Measure leak and load current with the 3293 The 3293 features 6 ranges from 30 mA to 1000A, offering ±5% rdg ±5 dgt measurement accuracy of 1mA leak currents. Leak current easurement Load current measurement3293 True RMS lets you measure even distorted currents accurately True RMS ensures accurate measurement, even of distorted load and leak currents ❏ Why does the same current yield different readings? Inverters, offi ce equipment, AC adapters - most load current waveforms are distorted. Current meters that display average rectifi ed RMS values does not allow you to obtain accurate RMS measurements. Averaging-type clamp on current meter True RMS clamp on current meter Loop a wrist strap through the small opening to help keep the instrument from being dropped Measure fl uctuating currents with the peak hold feature The 3291 and 3293’s peak hold feature (with bar graph hold) lets you capture peak values for currents that fl uctuate due to load variability. Current (A) Time Peak value display Peak value is held on the bar graph. 3293 Actual Size 1000A600.0A60.00ARange Leak current easurement Load current measurement3291 Push and hold for 2 seconds to activate fi lter ❏ Easy measurement of the peak value of a fl uctuating current. *Holds the peak value for data updated approximately 2 times/second.
