Tipdrift
Tipdrift is the phenomenonwhen a false LED light response is registered as the unit is quickly turnedor swept indramatic
arcmovements. Tipdrift is inherent to all dual thermistor leakdetector technology and is based in large part on the asymme-
try of the flow cells; shaking or tipping the unit influences the air flowprofileswhich impacts the rates of heat exchange. If the
device is functioning normally, the LED light signal will return to zero in 3-5 seconds after the unit is held still. In extreme
cases, the unitmay require another ‘zero’ cycle before using. To avoid tipdrift, be sure tohold the unit steadywhilemaking
measurements.
