    1. INTRODUCTION 2. GENERAL DESCRIPTION The Quest SafeLog 100 single gas detector is a compact, personally worn unit, which measures either oxygen or one of eight possible toxic gases. The 2.1 SafeLog 100: measured levels of these gases are shown in a backlit, four-digit LCD The SafeLog 100 is an extremely rugged, light-weight single gas datalog- display.

  • Page 4: Sensors

    2.2 Sensors: 2.3.4 STEL: The SafeLog 100 uses sensor modules with onboard memory that contains This annunciator, which stands for Short Term Exposure Limit, is present information about the individual sensor including: sensor identification, only when using a toxic gas sensor. Toxic gases may have STEL's which alarm setpoints, calibration data, and temperature compensation are higher than the eight hour TWA.

    2.3.9 PEAK: 3. UNIT OPERATION This annunciator appears during the RUN mode when the peak level and, in the case of the toxic gases, the peak STEL are shown. 3.1 Turning the Unit ON: Press ON/OFF. The following startup sequence will occur. 2.3.10 CAL: This annunciator appears during the SETUP mode when changing the cali- 1.

    3.3 Setup Mode: 3.3.5 Confidence Chirp Status: With four dashes in the display, press the setup key to enter the SETUP The confidence chirp feature gives a single audible chirp every 30 seconds mode. The display shows four zeros representing the password. Use the while the unit is running.

  • Page 7: Print Mode (Reset)

    3.5 Print Mode (Reset): Zeroing the sensor adjusts for small baseline drifts which occur over time in electrochemical sensors. 3.5.1 Print: From the display with four dashes, pressing the PRINT key enters the PRINT mode. The display will show "PrLL" or "SEr" based upon which Zero the unit by pressing the zero key from the display with four dashes or cable, parallel or serial, is plugged into the unit.

    The following alkaline batteries are recommended for intrinsically safe use Make sure the calibration gas cylinder is turned on and that it is the correct of the SafeLog 100: gas for the sensor being calibrated. Check the concentration of gas in the cylinder and make sure it matches the unit's calibration level setting.

MAINTENANCE Note: While the case is open the unit is not intrinsically safe; perform this When the unit is stored or not in use for extended lengths of time, it should be exercise in a non-hazardous area. Allow the new sensor to stabilize. calibrated, functionally tested, and its battery should be checked or changed at Zero and calibrate prior to use.
