Hioki clamp meters are best in class handheld current and voltage meters for safely and accurately measuring power lines. The CM3286 clamp on power meter can measure voltage, current, power, power factor, phase angle, reactive power or frequency, as well as detect phase sequence on live lines at any desired point of a single-phase circuit or three-phase circuit. CAT IV 600V, CAT III 1000V Key Features • Display four parameters simultaneously • A handheld power meter that measures from 5 W of power and 60 mA of current Measure power ranging from 5 W at a low current of 60 mA to 360 kW • In addition to current, voltage, and power, measure simple integral power consumption and phase sequence • Features and functions deliver fast and efficient testing • Hold measured values to send them to a smartphone, quick and easy data recording (CM3286-01 only) Data can be downloaded to tablets and smartphones using Hioki’s dedicated apps available from the Google Play or App Store. (CM3286-01 only) Search for “HIOKI” and download the “GENNECT Cross” app. *Android, Google Play and the Google Play logo are trademarks of Google Inc. *iOS is a registered trademark of Cisco Technology, Inc. and/or its affiliates in the United States and certain other countries. *iPhone, iPad, iPad mini, iPad Pro and iPod touch are trademarks of Apple Inc. *Apple and the Apple logo are trademarks of Apple Inc.

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)
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.
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.
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.
