Using Continuous Data Transfer Mode (MP225 only) In continuous data transfer mode readings are sent to the data output approximately every second. If the measurement endpoints (manually, or using auto endpoint) data transfer stops. If you recall memories all stored readings are output, (from the first to the last stored). To select continuous data transfer mode press and hold R for 2 seconds. n To maintain continuity of sample readings calibration data is only output at endpoint. Resetting Sample ID (MP225 only) The sample identity number is sent to the serial output and increments 1 every time a sample measurement endpoints. To reset the sample ID number to 1, press and hold Read for 2 seconds. The sample ID icon flashes three times to show the number has been reset. Recalling Calibration Data (MP225 only) You can only recall calibration data if the current measurement has endpointed - press Read if necessary. Press and hold Cal for 2 seconds. The display shows the date and time of the last calibration, the buffer value, the mV offset (E ) for 1-point 0 calibrations, and the slope value (%) for 2 (3) point calibrations. 7
