PC connection: Connect the PC through a USB cable, install OpenChoice software, and achieve real-time waveform display and data export.
Safety and Maintenance
1. Safety regulations
Grounding requirements: A power cord with a grounding pin must be used, with a grounding resistance of ≤ 0.1 Ω to avoid electric shock;
Overvoltage protection: The maximum voltage of the input channel is ≤± 400V (DC+AC peak). If it exceeds this limit, a high-voltage probe should be used;
Environmental restrictions: working temperature 0-50 ℃, relative humidity 5% -90% (no condensation), altitude ≤ 3000m.
2. Troubleshooting
Troubleshooting steps for possible causes of fault phenomena
There is no display when starting up. The power supply is not connected or the power module is faulty. ① Check the power cord connection, ② Replace the power socket, ③ Contact for repair
Unstable waveform triggers improper settings/poor probe contact ① Reset the trigger level to 50% according to Set to, ② Reconnect the probe, ③ Turn on noise suppression
The measurement deviation is large, and the probe is not compensated/the attenuation setting is incorrect. ① Perform probe compensation, ② Check that the probe attenuation is consistent with the menu settings
