When WT210/WT230 compatibility mode is enabled, the following IEE 488.2 mode utilizes the communication commands of the WT210/WT230. Therefore you can use communication commands to receive the voltage data Urms, Umn, or Udc selected by the display mode. You can only read and receive data for one measurement type RMS, MEAN, or DC at a given time.
When the WT210/WT230 compatibility mode is disabled, the following IEE 488.2 mode utilizes the communication commands used by the WT300. Therefore you can use communication commands to receive the voltage data Urms, Umn, Udc and U (decided by the display mode) simultaneously.
In summary, when using LabVIEW, you can receive the Urms, Umn, and Udc values simultaneously using the WT300's original IEE 488.2 mode. When you set the WT300 into WT210/WT230 IEE 488.2 compatible mode, you can not receive Urms, Umn, and Udc simultaneously.
Measure characteristics of devices that generate, transform or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics, and efficiency.
