Chapter 1 Calibration Notices RIGOL Chapter 1 Calibration Notices Calibration Interval Regular calibration can ensure the performance specifications of DP800. You are recommended to calibrate the instrument at a one-year calibration interval. Please perform regular calibration if higher accuracy is required.
RIGOL Chapter 1 Calibration Notices To Acquire the Calibration Service RIGOL does not recommend manual calibration by users. If calibration is required, please contact RIGOL customer service department or the local distributor. Recommended Test Devices It is recommended that you use the test devices listed in the table below or other test devices whose performance specifications satisfy the “Performance Requirement”...
Chapter 2 Calibration Process RIGOL Chapter 2 Calibration Process Warm the DP800 up for at least 30 minutes. Press Utility Test/Cal ManualCal, input the correct password using the numeric keyboard. Then, press OK to enter the calibration interface as shown in the figure below (take DP831A as an example).

RIGOL Chapter 2 Calibration Process Note: The differences between the V DAC calibration steps of the channels which support the Sense function (CH2 of DP821A and DP811A) and the above calibration steps are as shown below. The following operations should be performed before the first step (connect the channel output terminals of DP800 with the voltage input terminals of the digital multimeter).
Chapter 2 Calibration Process RIGOL V ADC Calibration Make sure that DP800 has been warmed up for at least 30 minutes. Connect the channel output terminals (take CH1 as an example; the calibration method is also applicable to CH2 and CH3) of DP800 with the voltage input terminals of the digital multimeter using the test leads as shown in Figure 2-2.

RIGOL Chapter 2 Calibration Process Short-circuit the (-) terminal of the output terminals with the (S-) terminal of the Sense terminals of the corresponding channel using the short circuitor. Turn on the Sense function of the corresponding channel before the second step (enable the channel output).
