AC CLAMP POWER METER
CM3286

Broad measurement range

Delivering a broad range of measurements at sites from manufacturing plants to households
Accurately measure power from 5 W at a current as low as 60 mA to 360 kW at a maximum of 600 A (single-phase power measurement)

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

Easy-to-see display

Related parameters and connection locations shown on the display at once (Main parameter×1, Sub-parameter×3)

Quick and easy data recording (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.

*Available for Android and iOS devices
*GENNECT Cross (freeware) is required to use instruments with a smartphone or tablet.

Simple wiring guide

The CM3286 provides a simple on-screen guide indicating how to connect it to a 3-phase circuit.

Built-in AUTO HOLD function

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.

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.)

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.).

Accurately detect electricity theft

The CM3286 is ideal for verifying electricity theft since it can measure both AC power and current.

● Meter tampering: Detect by comparing electric meter readings and measurements Proper operation of electric meters can be confirmed by comparing meter readings and actual values.

● Direct theft: Detect by measuring current Electricity theft can be detected by measuring current on the power supply side of the illegal connection.

Electricity theft detection-and-report function (CM3286-01 only)

The instrument’s electricity theft detection-and-report function can be used to quickly and easily make measurements and generate reports (CM3286-01 only).

Simply follow the measurement procedure to take measurements and photographs at four locations and the instrument will automatically generate a report, complete with photos.

Since the report is generated automatically in the field based on captured measurement data, it’s impossible for others to alter the data.
