1. The microprocessor controls the components of the instrument and interprets and records the signal generated by the photoionization detector PID Recorded data and setup information entered into the microprocessor s memory are retained when the Multi PID 2 is turned off A pump continuously pulls the air under test through the Multi PID 2 s PID The Multi PID 2 converts the concentration of photoionizable compounds in the sample into an electrical signal The microproces sor subtracts any background from the signal and divides this signal by a sensitivity obtained by calibrating with a standard gas of known concentration This concentration appears on the Multi PID 2 s dis play and depending on the values entered through the Multi PID 2 s keypad an alarm status may be displayed and an audio signal may be heard The Multi PID 2 can detect thousands of different types of airborne gases and vapors and its response depends on the characteristics as well as the concentration of each compound The Multi PID 2 does not distinguish one type of compound from another but displays a number indicating the total concentration of all photoionizable compounds in the sample 20 00623767 04 eps Introduction A standard of isobutylene at a known concentration may be used for setting the sensitivity If the Multi PID 2 is calibrated with isobutylene it displays concentrations in units equivalent to ppm of isobutylene If isobutylen
