Good Design Award 2017

Comment from the Good Design Award 2017

“The CM3286/CM3286-01 offers an extensive range of measurement functionality in a compact footprint, most notably the ability to check for electricity theft in emerging nations. The award recognizes how the product has carried on Hioki’s proven clamp meter design while offering the functionality and ease of use that customers have come to expect from such instruments, along with a highly socially significant design that demonstrates an understanding of how workers check for electricity theft in emerging nations and applies the results of observing how such products are used in the field in order to create a more useful instrument. One hopes that the product will serve to eliminate the problem of electricity theft.”

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)

<Measurement line>
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

GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports.
The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos.

Simple wiring guide

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

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.

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.)

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.

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.
