6. Place the new hydrophobic filter back into the metal clamp. Replacing the Charcoal Filter NOTE: The charcoal filter does not normally need to be replaced in the 35-3010A-13 because it does not include a CO sensor. 1. Turn off or unplug power to the controller. -
Page 23: Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 9 to 12 months is adequate for most sample draw detector applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 9 months for the sample draw detector. -
