摘要：
A method of using an electronic toolset for locating, reading, adjusting andconfirmingadjustment of an implantable bodily fluid drainage system without requiringrecalibrationfollowing adjustment from a current valve setting to a new valve setting usingan electronictoolset including an adjustment tool having a magnetic element and anindicator toolincluding a sensor array. The need to remove the electronic toolset from thepatient torecalibrate or zero the sensor array prior to confirming the new valve settingis eliminated.This is realized by disposing a ferromagnetic system component of theindicator tool in amagnet shield cage made of a metallic alloy to prevent magnetic fieldsproduced by amagnetic element in the adjustment tool during the adjusting step frominfluencing the sensorarray.
