Owon CMS101 clamp meter
Details
The Owon CMS101 is an AC/DC clamp meter and oscilloscope in one meter.
The clamp meter can measure both AC and DC voltages of up to 1000V and AC and DC currents of up to 1000A.
In addition, the CMS101 can also measure resistance, capacitance, frequency, duty cycle, and non-contact voltage.
The oscilloscope function has a bandwidth of 1kHz and be used to measure current and voltage waveforms, allowing for comprehensive analysis.
The measurement values include the maximum and minimum values as well as the peak-to-peak, RMS and average values.
The CMS101 has a maximum jaw size of 38mm, suitable for measurements in confined spaces and large wire diameters.
Furthermore, the CMS101 has a recorder function that can be used to display, compare, analyse and store measurement data through the mobile app.
The CMS101 features Bluetooth communication, supporting both Android and IOS and can also be used to remotely control the device.
Finally, the CMS101 has a 2.8", 20000 count LCD.
Before switching measurement functions, make sure all connections are disconnected to ensure accurate readings.
