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
2
O at 4 °C, inH
2
O at 20 °C, kPa,
cmH
2
O at 4 °C, cmH
2
O at 20 °C, bar, mbar, kg/cm
2
, 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 cmH
2
O, mbar, and mmHg units, and 3000 psi in inH

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.
3. Press
S to enter pressure switch test mode. The
Calibrator will display CLOSE instead of a mA
measurement.
4. Apply pressure with the pump slowly until the switch
opens.
Note
In the switch test mode, the display update rate is
increased to help capture changing pressure
inputs. Even with the enhanced sample rate,
pressuring the device under test should be done
slowly to ensure accurate readings.
5. OPEN is displayed once the switch is open. Bleed the
pump slowly until the pressure switch closes. RCL
appears on the display.
6. Press
S to read the pressure values for when the
swith opened, for when it closed, and for the
deadband
Hold
S for 3 seconds to reset Switch Test mode; hold
any other key for 3 seconds to exit.

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.

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
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.
