Pressure Calibrator

Introduction

The Fluke 718 Series Pressure Calibrators do the following:

• Calibrate P/I (pressure to current) transmitters

• Measure pressure via a 1/8-inch NPT pressure fitting

and an internal pressure sensor or via a Fluke 700 Series Pressure Module

Source pressure

•

• Measure current up to 24 mA

• Simultaneously display pressure and current

measurements.

• Supply loop voltage

• Calculate mA percentage in Percent Mode

• Calculate mA error % in Percent Error Mode

The 718 Pressure Calibrators (hereafter, “the Calibrator”) include:

• 718 1G

• 718 30G

• 718 100G

• 718 300G

The Calibrator makes 5-digit pressure readings in the following units: psi, inH cmH2O at 4 °C, cmH2O at 20 °C, bar, mbar, kg/cm2, inHg, and mmHg.

Pressure sensor specifications are as listed under “Pressure Sensor Input”.

The Calibrator measures pressure sensor inputs in the units shown in Table 1.

For pressure modules, full scale readings for all pressure ranges can be made in psi, kPa, and inHg units. To avoid display overflow, full scale readings are limited to 1000 psi in cmH2O, mbar, and mmHg units, and 3000 psi in inH2O units. Pressures of at least 15 psi must be measured for meaningful readings in bar and kg/cm2 units.

Your Calibrator is supplied with a holster, two installed 9 V alkaline batteries, one set of TL75 test leads, one set of AC70A alligator clips, one 700-ILF In-Line Filter (to protect the pump), a Product Overview Manual, and a CD-Rom.

If the Calibrator is damaged or something is missing, contact the place of purchase immediately. Contact your Fluke distributor for information about accessories. See

Rotate forward (clockwise) for pressure, backward (counter-clockwise) for vacuum.

Rotate fully backward (counterclockwise) to release all pressure or vacuum. (Rotate slightly for partial release.) Rotate fully forward (clockwise) to close valve.

Rotate either direction for precise adjustment of applied pressure or vacuum. Full rotation is about 30 turns.

Increase pressure on the inward stroke. In vacuum mode, decrease pressure on the outward stroke.

Calibrating a P/I Transmitter

To calibrate a P/I (pressure to current) transmitter, apply a pressure to the transmitter and measure the transmitter’s current loop output. You can apply pressure with the Calibrator’s internal pump or with an external pump.

XW Warning

To avoid a violent release of pressure or vacuum, always depressurize the system slowly using the pressure/vacuum release control before detaching any pressure line.

Using the Internal Pump

The internal pump can provide the rated pressure for all Model 718 Calibrators.

The preferred use for the internal pump is shown in Figure 4, where the Calibrator displays pressure measured with the internal sensor and provided by the internal pump.

The internal pump can also be used with certain Fluke 700 Series Pressure Modules. In this case, pressure measured by the Pressure Module is displayed by the Calibrator. Appropriate pressure modules for each Calibrator model are identified in Table 6 . Figure 5 shows the internal pump being used with a pressure module.

Page 19

Pressure Calibrator Calibrating a P/I Transmitter

XW Warning

If both a pressure module and the internal sensor are connected, the Calibrator displays ONLY the pressure module measurement.

To use the Calibrator’s internal pump, refer to Figure 3 and perform the following steps:

1. Depressurize and drain the line before connecting the Calibrator.

2. Connect the pressure transmitter to the Calibrator internal sensor as shown in Figure 4 (for internal pressure sensor measurements) or Figure 5 (for pressure module measurements.)

Note

To avoid leaks, use Teflon tape or similar sealant on all pressure connections.

3. Make sure the pressure/vacuum switch is in the desired position. Forward (clockwise) is for pressure; backward (counter-clockwise) is for vacuum.

4. Turn the pressure/vacuum release control backward (counter-clockwise) to vent pressure/vacuum from the pump.

6. Turn the fine adjustment knob to mid-range.

7. Turn the pressure/vacuum release control forward (clockwise) to close the release valve.

8. Work the pump handle in and out to apply incrementally larger pressure/vacuum changes. Shorten the stroke to apply smaller increments of pressure/vacuum change.

9. To make very small pressure/vacuum changes, use the fine adjustment knob.

Note

This knob adjusts a small internal reservoir to vary the total volume. With larger external pressure/vacuum volumes, this control will adjust pressure or vacuum within a smaller range.

10. Depressurize the system before disconnecting the pressure line.

5. Press

Z to zero the pressure display.

Pressure Calibrator Pump Valve Assembly Cleaning Instructions

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 o-ring 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.

718 Series Users Manual

Using an External Pump

XW Warning

To avoid damage to the Calibrator and possible release of pressure, do not connect the internal sensor to an external pressure source that exceeds the maximum rated pressure.

To develop higher pressure or vacuum, use an external pump (such as the Fluke Model 700PTP). Use a Fluke Pressure Module connected to the pressure module input on the Calibrator. Pressure modules are listed in Table . Make overall connections as shown in Figure 6.

Refer to setup and operating instructions included with the pressure module and pump.
