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

Switch Test

To perform a switch test, do the following:

Note

This example uses a normally closed switch. The
procedure is the same for an open switch but the
display reads OPEN instead of CLOSE.

1. Connect the Calibrator mA and COM terminals to the
switch using the pressure switch terminals and
connect an external pump between the Calibrator and
the pressure switch. The polarity of the terminals does
not matter.

Note

If using an external pump, connect the pump to
the Calibrator and to the input of the switch using
a tee fitting.

2. Make sure the vent on the pump is open and zero the
Calibrator if necessary. Close the vent after zeroing
the Calibrator.

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.

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.

5. Press

Z to zero the pressure display.

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.

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.
