When Z3210 is installed -
Hioki clamp meters are best in class handheld current and voltage meters for safely and accurately measuring power lines. The CM3286-50 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 600 V, CAT III 1000 V
Easy! Just connect the Z3210 Wireless Adapter to your Hioki compatible instrument, to make it Bluetooth® ready.
Wirelessly connect Hioki-compliant instruments with a simple connection.
Transfer measurements to your smartphone or tablet and quickly create reports with field photos and drawings.
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
- Harmonic analysis from 1st to 30th order with GENNECT Cross (Wireless Adapter Z3210 is necessary)
- Easily transfer measurement data to your smartphone or tablet by using our free app GENNECT Cross or to an Excel® file (Wireless Adapter Z3210 is necessary)

Data can be downloaded to tablets and smartphones using Hioki’s dedicated free app "GENNECT Cross," available from the Google Play or App Store.
Wireless communication capability for even greater convenience
Instantly create reports by a free app (GENNECT Cross) (*1)
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.
Excel® Direct Input Function (*1)
Boost work efficiency in the field by letting you directly transfer measurement data to (i.e., enter measured values directly into) templates created as Excel®.
- *1:The optional Wireless Adapter Z3210 is required.
Helping personnel analyze issues in the field
Harmonic measurement
When combined with GENNECT Cross (*2), you can perform simple harmonic analysis. Applications include problem analysis of power supply systems.
Problems that can be caused by harmonics
- Equipment burn-out and destruction due to overheating
- Malfunctions of power control devices
- Increased loss along with reduced service life and efficiency for power devices
- *2:GENNECT Cross is an free app that lets you connect field measuring instruments to smartphones and tablets using Bluetooth® communications. Wireless Adapter Z3210 (sold separately) is required in order to pair the instrument with GENNECT Cross.
More recommended features
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)
<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
Related parameters and connection locations shown on the display at once (Main parameter×1, Sub-parameter×3)
Simple wiring guide
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
CM3286-50 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 CM3286-50 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
CM3286-50 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 CM3286-50 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.
The instrument's electricity theft detection-and-report function can be used to quickly and easily make measurements and generate graphical reports with GPS geo tags.
Getting telltale evidence of electricity theft involves more than just saving a record of measured values. Time and date, GPS data, measurement photographs, and measured values are captured as a series of photographs are taken and grouped together into a report.
Phase sequence detection
Detect the phase sequence of the 3-phase power line with easy-to-see display.
