To calibrate the MHO934, use the Self Calibration function in the utility menu. This procedure automatically adjusts the internal ADCs and timing. It is recommended to run calibration when the ambient temperature changes significantly or after prolonged storage.
What is the maximum input voltage for the channels?
The maximum input voltage is CAT II 300 Vrms. Do not exceed this rating to avoid damaging the oscilloscope or risking electric shock. For higher voltages, use a suitable attenuator probe.
How long does the battery last on a full charge?
The built-in lithium-ion battery provides up to 4 hours of continuous operation. Battery life may vary depending on display brightness and measurement activity. To conserve power, use the auto shutdown feature.
Does the MHO934 support FFT analysis?
Yes, the MHO934 includes a built-in FFT function for frequency domain analysis. You can access it via the Math menu, select FFT, and configure the window type (Hanning, Hamming, etc.) and the number of points.
Can I connect the oscilloscope to a PC?
Absolutely. The MHO934 provides a USB Host/Device port and an Ethernet (LAN) port. Connect it to your PC via USB and use the provided software or standard SCPI commands for remote control and data acquisition.

Yes, the MHO934 is well-suited for automotive diagnostics. Its 300 MHz bandwidth and 4 channels allow monitoring of CAN bus, sensor signals, and ignition waveforms. Always use the proper probe settings and ensure the ground connection is secure.
How do I perform automatic measurements on a waveform?
Press the Measure button, then select from a range of automatic parameters (Vpp, frequency, rise time, etc.). The oscilloscope displays up to 5 measurements simultaneously. You can customize the measurement source and thresholds in the measurement setup menu.
What safety precautions should I take when using the MHO934?
Always adhere to the safety instructions in the manual. Use the supplied power cord with a grounded outlet, never touch exposed conductors when the device is powered, and respect the maximum input voltage.
