Oscar Measurements/eForms demonstration

OscarMeasurements/EForms demonstration. Each field has a property:

• read: Only reads the measurement data, and even if changed, these values will not be written to measurements.
• write: Writes the contents of the field to measurements unless left blank, but will not prefill the old value.
• read/write: Prefills the old measurement data, and if changed, the new values will be written to measurements.
• Note: Regardless of read/write the values will be saved in eforms.
