How to Use Hioki Clamp Meters: Using the Wireless Feature to Display Data on a Mobile Device
Measured values captured by the Hioki CM4372 and CM4374 AC/DC Clamp Meters can be displayed and saved onto a mobile device wirelessly. The results can also be used to create automatic reports. Simply install the free GENNECT Cross app onto your mobile device and connect to the Hioki clamp meters. Reports created on your mobile device can even be e-mailed to the office to further increase work efficiency.
How to Use the Hioki CM4370 Series Clamp Meters Auto Hold Function:
The Auto Hold feature is perfect in situations where the display is hard to read because the clamped wires are in hard to reach locations. With Auto Hold, measured results automatically freeze on the display until the next measurement starts, making testing and record taking a snap.
How to Use the Hioki CM4370 Series Clamp Meters Simultaneous Display of DC Current and DC Voltage:
The CM4370 Series can measure both DC current and DC voltage with a single device at the same time, making it ideal for automotive battery testing and inspection and maintenance of solar panels.
How to Use the Hioki CM4370 Series Clamp Meters Inrush Measurement Function:
Accurately measure the startup or inrush current of motors and equipment. The CM4370 series is engineered to detect the full startup current period and then identify the RMS waveform as well as the highest waveform peak.
How to Use the Hioki CM4370 Series Clamp Meters Continuity Check Function:
The DMM function of the AC/DC clamp meter also provides a continuity check function. Easily detect short-circuits with the clear buzzer and red LED.
How to Use the Hioki CM4370 Series Clamp Meters AC Voltage Detection Function:
The tip of the current sensor of the CM4370 Series can also detect live voltages, eliminating the need for you to use a separate voltage detector. Energized lines are identified with a loud buzzer and red LED on the clamp meter.
