    7.1 Unpacking Verify that there is no shipping damage. If there are signs of damage, immediately contact the shipper, then Teledyne API. Remove the cover and check for damage inside, particularly the glass GPT reaction chamber. Check the line voltage decal on the rear panel. Verify that it matches your local power. (The M702 is not frequency-sensitive.)

  • Page 37: Setting Dilution Flows

    Teledyne API Model 702 Precision Calibrator Instruction Manual 9 SETTING DILUTION FLOWS CAUTION We recommend that the M702 be set and kept at one flow for GAS and one flow for DILUENT. 9.1 Recommendations While it is possible that the M702 can be used as a multi-point calibrator, WE DO NOT RECOMMEND IT.

  • Page 38: Verifying Flows

    9.2 Verifying Flows 9.2.1 Diluent Flow 1. Connect the Zero Air Generator (Teledyne API Model 701) to the ZERO AIR IN port. 2. Set the Zero Air Generator output pressure to 35-50 psig. 3. Connect an NIST-traceable flow measurement device (mass flow meter, soap-film flowmeter or dry piston flowmeter) to the rear panel CAL GAS OUT port.

    Teledyne API Model 702 Precision Calibrator Instruction Manual 7. Select a gas pressure by adjusting the GAS PRESSURE regulator knob. 8. Measure the corresponding flow. 9. Adjust the gas pressure until the desired flow is obtained. 10. Note the gas pressure and use as an indication of flow.

  • Page 40: Example

    Teledyne API Model 702 Precision Calibrator Instruction Manual 9.2.4 Example Say you want to set a span gas of 450 ppb and require at least 1000 ccm to support your analyzer. Start with the DILUENT flow at 2000 ccm and the cylinder flow at 20 ccm.
