The user interface for the R Checkitem is the same as that for the E Checkitem. The R Checkitemcan be useful with patient simulators (e.g. ECG, SpO2, or NIBP) which do not, by themselves, generatemeasurement data.When ES601-US executes the R Checkitem, it will transmit the command portion of the Checkitem via theTester Port specified in the AutoSequence. The prompt portion of the Checkitem will be displayed on theLCD as the "TASK". The ENTER TEST DATA button on the LCD allows the user to recordmeasurement data or observations via the QWERTY touch keypad, or by means of a PS/2 keyboardconnected to ES601-US.
