VersaporR Membrane” on page 10. If the calibration/response difficulties continue, replace the plug-in sensor as described later in this section. If the calibration/response difficulties continue, contact RKI Instruments, Inc. for further instruction. Replacing Components of the Toxic Detector This section includes a procedure to replace the plug-in toxic sensor, the VersaporR membrane, and the entire toxic detector assembly. - Page 14 Peel off the VersaporR membrane. It may be necessary to clean off the sensor face to remove any residue left from the adhesive backed membrane. Install the new membrane on the face of the plug-in sensor. Plug the sensor back into the four-socket pattern in the detector housing body. 10 • 65-2302/65-2303 Toxic Detector...
