Fluke 718 Pressure Calibrator

The complete solution to pressure calibration
The Fluke 718 pressure calibrator family ( 4 models) provide a total pressure calibration solution for transmitters, gauges and switches. This compact pressure calibration solution is about a third of the size of comparable instruments and weighs just one
kilogram ( two pounds) . The unique, easy to clean out access ports built into the pump protect the pump from fl uids and provides the ability to service the pump without disassembly.

* Pressure Source and Milliamp Measurement to calibrate and maintain almost any pressure device
* Integrated pump is easily cleaned when accidentally exposed to fluids:

- reduces cost of ownership and repairs
- service the pump in the field

* Error % calculation for quicker pass/ fail decision making in the field
* Best in class mA accuracy of 0.015 % for better measurement confi dence and workload coverage
* Min/ Max/ Hold to capture changing measurements
* Switch test feature for quicker and more accurate pressure switch testing
* New 1 and 300 PSI pressure ranges mean fewer extra tools required
* 1, 30, 100 & 300 PSI ranges now available

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 fl uids from entering the pump and causing damage.
These two check valves allow the bi-directional fl ow of air into or out of the 718. Even after draining the process fl uid from the calibration port of the device under test, minute amounts of process fluids may often still be lurking behind. In the event these
fl uids 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 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 oring and spring assemblies into the valve body.
9. Reinstall the retention caps and gently tighten the cap.
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.
