Appendix A : Technical Indicators
Unless otherwise specified, all technical specifications apply to probes with a attenuation
setting of 10X and the UT4000 Series Digital Oscilloscopes. To verify that your
oscilloscope meets specifications, it must first meet the following conditions :
 The oscilloscope must have been operating continuously for thirty minutes within
the specified operating temperature.
 If the operating temperature changes by more than 5°C, you must perform the “Self
Cal” operation, accessible through the System Functions menu. All specifications
are guaranteed unless noted “Typical”.
