问题详述
我正在尝试使用Calibration Executive来校准PXI-4461。在预热步骤中，我收到以下错误消息：
Error -200112 occurred at DAQmx Initialize External Calibration.vi: 3390001.
Possible reason(s):
Calibration handle is invalid.
Open a calibration session to get a valid calibration handle. Use the valid calibration handle obtained when the calibration session was opened.
