Warning When making VOC measurements use only Supplied Viton sample line as other sample lines may absorb VOC s thus resulting in incorrect readings Warning Hand Aspirator The LEO is primarily designed to be used with a built in pump for remote sampling The hand aspirator can be used for indicative sampling but it must be noted that when using a hand aspirator a reading error in the region of 20 is possible In addition whereas the pump can sample quickly and accurately with up to 30 metres of sample line the hand aspirator must only be used with up to 10 metres of sample line and the sample time is extended The sample line must be intact and the proper flow established Remote sensing is carried out with the inbuilt electric pump option or by the hand aspirator for non reactive gases using the sample connector at the bottom of the instrument and sample tubing supplied with your instrument On pumped models the pump is off after start up Pump Option Press and hold the green RH button to start or stop the pump The pump will run at normal speed for remote sampling When the pump is running at normal speed a pump symbol I rotates in the display as shown in Fig 2 17 Note It is only possible to switch the pump ON OFF when instrument alarms are inactive og 20 9 oz 000 ooo 0 0 Fig 2 17 Pump Symbol Displayed Unrivaled Detection Page 17 of 36 www ionscienceusa com LEO MANUAL lon Science Inc Operatio
