To make detections as easy as possible the generating of the livelist the Slave diagnosis and Slave related transmission level detection should be effected as well from the bus end However you can also make these from any other available measuring point within one segment Here please observe that the function of the livelist and of the SlaveDiag also work via a repeater segment coupler or optical coupler The level detection of a Slave connected via such a device reflects only the transmission level of the repeater and not the one of the detected Slaves 4 3 Measurement at the running bus The measurements at the running bus are limited to an indication of the current baud rate as well as of the general transmission level quality of the connected Slaves By this means a qualitative evaluation of the level on the bus line is made If the test tool shows reflections the reasons for those can only be found with the line detection which implies that the Master s is are being turned off 6 COMSOFT NetTEST II Menu Guide 5 NetTEST II Menu Guide 5 1 Start Up Setting in Operation Check the completeness of the scope of delivery and charge batteries before first setting in operation Remove the battery by gently pressing the locking and at the same time pulling down the battery placed at the rear lower side of the NetTEST II Now place the battery into the charging holder and check the loading procedure by means of the LED in the
