As soon as the respective measuring cycle is finalized the recent data are shown
For the description of the acquisition windows see 7.1.
The measurement data stored by the AlphaGUARD can be downloaded at any
time, i.e. during or after the measurement, on a PC when connected to the
monitor via USB or RS232 cable or via Bluetooth (see DataVIEW or DataEXPERT
manual).
Flow mode (DF2000)
Flow measurements can be performed either in the form of an open or a closed
gas circuit. Following preparatory measures of configuration are necessary:
x Check if flow through adapter is mounted. If not, unscrew the diffusion
adapter by hand and screw the flow through adapter by using the
hexagon key (see Figure 50
x Start the AlphaGUARD by pushing the ON/OFF button
x Check if set operation mode is OK (1 or 10 min, flow, Radon). If necessary,
change the required operation mode via menu (see 7.2.3) or by means
of a PC connected to the AlphaGUARD using DataVEIW or DataEXPERT
software (see DataVIEW or DataEXPERT manual).
x If mains operation is required (when battery is discharged and/or for long
term operation) simply connect the mains adapter.
x If the pump flow gets out of control (indicated by an acoustic signal),
ensure that there is no interruption of the flow e.g. by sharp bended tubes
etc.
