Questionable Status Register of Single-channel Model
The SCPI status system of the single-channel model is as shown in Figure 1-3. Wherein, the questionable
status register provides voltage control, current control, over-temperature, overvoltage, overcurrent and
fan failure information. You can send the :STATus:QUEStionable[:EVENt]? command to read the register.
The definitions of the bits in the questionable status register of the single-channel model and the decimal
values corresponding to their binary weights are as shown in Table 1-4.
