Hioki CM3286-OB Clamp Meters - Type: Power Clamp Meter, True RMS: Yes, Maximum Current AC: 600 A

Measure power in single-phase to balanced three-phase circuits (with estimated values) (1-phase/ 2-wire, 1-phase/ 3-wire, balanced 3-phase/ 3-wire, and balanced 3-phase/ 4-wire). *The instrument generates estimated power values when measuring 3-phase circuits.

Easily check power supply fluctuations
Since it can display maximum (MAX), minimum (MIN), and average (AVG) values, the CM3286 is useful when you need to ascertain the magnitude of fluctuations. And since it can also measure crest (PEAK) values, you can use it to check fluctuations at the crest value level.

Support for large-diameter, high-current measurement
The CM3286 can be used with the optional Clamp On Adapter 9290-10 to measure busbars of up to 55 mm in diameter or 80 × 20 mm. Measure high currents of up to 1000 A AC (or 1500 A for up to 5 min.).

Quickly check for unbalance
The CM3286 can measure unbalanced power in a 3-phase/ 3-wire circuit by measuring the single-phase power twice and then automatically adding the results. (The instrument can also measure 3-phase/4-wire circuits in three separate measurements.)

Choose from an extensive selection of probe tips
Select the type of probe that best suits your measurement location, letting you measure in areas that can’t be reached with conventional probes and busbars that you wish to clamp between probes. *Probe tips: Sold separately.

Functionality and performance that enable a broad range of measurements

• White backlight - A white backlight makes the measured values stand out, even in dim locations. Owing to wide viewing angle display, high quality screen lets you read measurements from any angle.
• Easily operate with one hand - Turn the rotary switch while holding the instrument in the same hand. Grooves on the switch make it easy to rotate even while wearing work gloves.
• CAT IV 600 V - The CM3286 can safely measure service wires with a wire- to-ground voltage of up to 600 V as well as wires found in distribution panels. The clamp meters also feature a safe design that can withstand a transient overvoltage of 8 kV in case of a lightning strike.
• -25°C to + 65°C - The CM3286 can be used in freezing temperatures or on the hottest summer days.

Easy-to-see-diplay Related parameters shown on the display at once

• Simple wiring guide - The CM3286 provides a simple on-screen guide indicating how to connect it to a 3-phase circuit.
• AUTO HOLD - The clamp meters beep when the measured value stabilizes and then automatically hold the display value. This is useful when using the instrument in locations where it is difficult to see the display or press the hold button.
• Double warnings with sound and light - When the clamp power meter detects excessively over current or voltage input during a continuity check, it alerts you with a red backlight and beeping tone in order to help prevent accidents.

Quick and easy data recording Hold measured values to send them to a smartphone (CM3286-01 only)
When you freeze the measured value, it is automatically transferred to a smartphone or tablet, eliminating the need to jot down readings by hand. You can also create a simple PDF report right there in the field, and save data in CSV format for later editing in Excel.
