Before beginning these procedures, two conditions must first be met:

● The oscilloscope must have been operating continuously for thirty minutes within the

operating temperature range specified.

● You must do the Self Calibration procedure. If the ambient temperature changes by more

than 5℃, you must do the Self Calibration procedure again.

Test DC Gain Accuracy

Steps： 1、Set the DC voltage source output level to 30 V

2、Press the button “DEFAULT/SETUP” of oscilloscope

3、Set VOLT/DIV to 10V/div, set measure parameter as “CH1,Mean”

4、Connect the oscilloscope channel 1 to the DC voltage source, and record the value of

Mean appeared on the screen as V
