    The AMC-RAM3 provides a remote alarm indication when employed with monitors such as the AMC Gas Monitor 1B. Each RAM3 has a red strobe light to provide a visual indicator of an alarm condition and remains active until the alarm is cleared. The Audio alert is provided by a buzzer which emits a 2900hz tone at in excess of 90 dB(A) at a distance of 24 inches.

  • Page 40: Calibration

    5.3 CALIBRATION Sensors naturally degrade over time, losing about 2% of their sensitivity per month. Over time a sensor will start to underreport gas concentrations, meaning that a calibration is necessary to maintain a safe environment. When the Sensor Module(s) are due for calibration the respective LED will blink cyan-yellow as opposed to its usual green to be able to see at a glance which sensor(s) is(are) overdue.

  • Page 41: Pre Bump Test

    5.3.3 PRE BUMP TEST Before calibration, an “As Found” bump test) is usually performed to ensure each sensor is in working order and returning reasonable responses. The bump test involves applying a test gas to the sensor. However, sensors such as CO have a recovery time measured in multiple hours. As a result, the calibration routine would find a zero at a concentration that is not the true background concentration, should the sensor not have sufficient recovery time.

  • Page 45 Caution: In the case of repeated CO Gas Calibrations performed in quick succession (i.e. less than 30 minutes apart) first follow the routine outlined in section 5.3.3, Pre Bump Test. Then use the Background value provided by the unit during ADAPTiCAL startup. A CO sensor element has a tendency to increase its background zero offset after each span gassing.
