All sequential records with a time distance to the last record equal to the integration interval
are interpreted later as one measurement series. The measurement may be interrupted as
often as desired to finish the old and start a new measurement series. There is no limit for
the number of series. Single point measurements are also possible.
Printing a protocol
The RTM1688-2 enables the direct printout of acquired data on the portable protocol printer
AP 1300. Only the last acquired measurement series can be printed. Connect the printer to
the RTM by the adapter cable (9-pin SUB-D male to 3-pin round connector) included in the
delivery. To switch on the printer press the right button at the panel. The LED is constant,
green. Note: after about 30 seconds, the printer switches in the sleep mode if no print job is
carried out. To start a protocol print, the instrument has to set in stand-by mode - stop the
measurement in case of a running sample. Start the printing out by pressing the "TOGGLE"
button for at least 5 Seconds (wait for four beeps). During printing out the display will show
the phrase "...print protocol". If a new series was started unintended, the measurement may
stopped again before completing the first interval. The print data remain valid as long.
The protocol header contains the serial number of the instrument, the start and the end of a
measurement series, the Radon and Thoron average concentrations and the time period
used for averaging (between start and end of the test). The header is followed by the
records of the measurement series containing time stamp, Radon and Thoron concentration
and environmental sensor readings.
