  • Page 11: Initial Considerations

    1.3.1 Operating Range While the driest dew/frost point temperature capability specified for the MG-101 is -75°C (-103°F), the actual limit is determined by the moisture content of the dry nitrogen source and by the ambient temperature. The driest dew/frost point temperature the MG-101 can produce is the dew/frost point temperature of the dry nitrogen source plus 25°C (45°F).

    IMPORTANT: Be sure you read and understand “Initial Considerations” on page 3 before proceeding. To prepare the MG-101 for operation, complete the following steps: Remove the back panel by removing the two small screws at the bottom (see Figure 2 below).
  • Page 14 Selection Valve Vent Valve Inlet Fitting Outlet Fitting Figure 3: MG-101 Front Panel Connect the nitrogen supply to the MG-101 inlet fitting via the stainless steel pressure regulator, using 1/4” OD stainless steel tubing (see Figure 4 below). ® Note: Swagelok fittings are preferred throughout the installation.
  • Page 15 Chapter 2. Setup and Operation Connect the calibration chamber to the MG-101 outlet fitting, using 1/4” OD SS tubing. Then, leak test the connection. Note: Panametrics Sample Cell #2830 is the preferred calibration chamber for M2 Type probes At the outlet of the calibration chamber, connect at least 5 ft (1.5 m) of 1/4” OD tubing as a vent to atmosphere.

  • Page 18: Calibrating The Moisture Samples

    Check the saturator bottle temperature on the temperature gauge. For each moisture calibration point you wish to generate, look at Data Tables 2 and 3 (supplied with the MG-101). Above the line which reads “Generated Dew Points (Deg C),” is a row of values headed “Ambient Temperature (Deg C).”...

    A.2.1 Example 1 Data Table 2 is provided with the MG-101 to enable you to use the field calibration system to check sensor probe calibration without calculating the value of p . Data Table 2 was compiled by calculating p and thus, the dew/frost point temperature by Equation 2 on the previous page.
