  • Page 53: Sensor Limitations

    Persistent exposure to high levels of toxic gas can shorten the life of toxic sensors. Toxic sensors may also be cross-sensitive to gases other than their specific target gas, and hence the presence of other gases may cause the sensor to respond. If unsure, contact Crowcon or your local agent. Prologue Use of high power radio transmitters in close proximity to the instrument may exceed RFI immunity levels and cause erroneous indications.

  • Page 54: Charging And Run Times

    Run time is equal to the expected operating time following a full charge/discharge cycle. Prologue Should the Gas-Pro completely discharge, charge within 3 days. This will maintain the internal clock. Storage life with a fully charged battery is 8 weeks, reducing to 6.5 weeks after 500 charge cycles.
