Extended Reading Mode
Extended reading mode is used for occupational inspection work where the quantification of lower levels
of lead may be required. This usually entails longer reading times for the instrument. Extended Reading
Mode is broken down into four “sub” modes for the user: Stop at Set Level, Fixed Time, Unlimited Time,
and Stop at Statistics.
Stop at Set Level
Stop at Set Level mode allows the user to set up the instrument with three variables: action level, number
of standard deviations above the action level, and number of standard deviations below the action level.
Once these user-determined thresholds have been reached, the instrument will stop acquiring data, close
the safety shutter, and display a result. This mode may be useful for customers performing commercial,
industrial, and/or institutional Pb inspection work, where they are looking for the Pb200i to terminate the
measurement once customer-determined statistical confindence has been achieved.
To setup this mode, start at the main menu. Select Setup>Mode>Stop at Set Level (Fig. 141), set the
action level, SD’s above, and SD’s below (Fig. 142), and select the Back button (Fig. 143).
