  • Page 73: Calibration Introduction

    Routine Maintenance Calibration Introduction The Multi-PID 2 must be calibrated in order to display concentration in ppm units equivalent to the calibration gas. First, a supply of zero air, which contains no ionizable gases or vapors, is used to set the Multi-PID 2’s zero point.
  • Page 74 Routine Maintenance Compressed Gases Cylinders of compressed gas, such as calibration gas, must be hand- led with extreme care. For safety, the calibration gas cylinders must be secured before use. Please observe the following handling procedures: Mark each new regulator with its intended gas service and never use a regulator for more than one service.
  • Page 75 Adjust the delivery pressure and then open the regulator outlet valve. Calibration Gas Adequate ventilation must be provided when the Multi-PID 2 is being calibrated. If compound threshold limit values (TLV) are exceeded, you should use a gas bag for sampling and calibration.
