NOTE: TheGTA4100R advanced softwarehas a feature called zero suppression,whichmonitors thesensor performance and small sensor drifts,which is a characteristic of all sensors. This drift is due tosudden temperature,humidityandpressurechangesoragingsensors.Normally theadvancedelectronicsandsoftwarewillremovethisinsignificantdriftandkeepthedetectorreadingzeroor20.9(foranOxygensensor). However in isolatemode the zero suppression feature is turned off, so during calibration thechannelcanbeexactlyzeroedwithoutthedeadbandmasking.

WARNING: Isolatemodeof theGTA4100R allows you todisable the alarm LEDs,buzzer, and relaysduringcalibrationproceduresandresponsetests.Whencalibrationmodeisactivated,theLEDs,buzzer,andrelayswillnotoperateasdescribed in this section.Youmustdeisolate the channel tobring itback intooperation.
