Transferring Data to Handheld Software Tools
The Site Master has only one serial port, so it is not possible to communicate with both the
PSN50 sensor and a PC running Handheld Software Tools (HHST) at the same time. There-
fore, only saved measurements can be viewed in HHST when using the PSN50. To view
saved measurements, disconnect the serial cable from the PSN50 and connect it to the serial
port of the PC running HHST. Refer to the Handheld Software Tools chapter in this manual
for further information.
