Fluke 718-300G Fluke 717 and 718 Pressure Calibrator Datasheet - Page 2

The New 718 Calibrator Pump The new Fluke 718 is a uniquely protected pneumatic pressure calibrator and pump. The new pump design uses protective check valves that allow air to pass through the pump for calibration but inhibits fluids from entering the pump and causing damage. These two check valves allow the bi-directional flow of air into or out of the 718. Even after draining the process fluid from the calibration port of the device under test, minute amounts of process fluids may often still be lurking behind. In the event these fluids enter the 718 pump cavities, the new pump design enables quick cleaning and maintenance, even in the field. Pump valve assembly cleaning instructions 1. Using a small screwdriver, remove the two valve retention caps located in the oval shaped opening on the underside of the Calibrator. 2. After the caps have been removed, gently remove the spring and o-ring assembly. 3. Set aside the valve assemblies in a safe area and clean out the valve body using a cotton swab soaked in IPA (isopropyl alcohol). 4. Repeat this process several times using a new cotton swab each time until there is no remaining sign of residue. 5. Pump the unit several times and check again for residue. 6. Clean the o-ring assembly and o-ring on the Functional Specifications retention caps with IPA and inspect the o-rings closely for any cuts, nicks, or wear. Replace if needed. 7. Inspect the springs for wear or loss of tension. They should be approximately 8.6 mm long in the relaxed state. If they are shorter than this, they may not allow the o-ring to seat properly. Replace if needed. 8. Once all parts have been cleaned and inspected, reinstall the o- ring and spring assemblies into the valve body. 9. Reinstall the retention caps Cleaning the fluid trap in the Fluke-718 and gently Calibrator is quick, easy and only requires a tighten the cap. slotted screwdriver and cotton swab 10. Seal the output of the Calibrator and pump up the unit to at least 50 % its rated pressure. 11. Release the pressure and repeat several times to ensure that the o-rings seat properly. The Calibrator is now ready for use.
