HART Resistor
The Calibrator has a selectable 250 Ω HART resistor to
facilitate use with HART communication devices. Use a
HART communicator when measuring mA with loop power
or sourcing mA. The HART resistor defaults to OFF.
To turn on the HART resistor:
1. With the Calibrator OFF, press O.
2. When HArt is displayed, press Vor U to turn on/off.
Power Saver
The Calibrator automatically turns off after 30 minutes of
inactivity. To reduce this time or disable this feature:
1. With the Calibrator OFF, press O.
2. P.S. xx is displayed, where xx is the turn-off time in
minutes. OFF means the power saver is disabled.
3. Press
Vor U to decrease or increase the turn-off
time.
4. To disable, press Vuntil the display shows OFF.
The Calibrator resumes normal operation after 2 seconds.
Switch Test
To perform a switch test:
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
switch opened, for when it closed, and for the
deadband
Hold S for 3 seconds to reset Switch Test mode; press
any other key to exit.
Zeroing with Absolute Pressure Modules
For zeroing, adjust the Calibrator to read a known
pressure. This can be barometric pressure, if it is
accurately known, for all but the 700PA3 module. An
accurate pressure standard can also apply a pressure
within range for any Absolute Pressure Module. Adjust the
Calibrator reading as follows:
1. Press and hold Z.
2. Press
Z to increase or Y to decrease the Calibrator
reading to equal the applied pressure.
3. Release Z to exit the zeroing procedure.

Set Maximum Pressure Limit
To set a maximum pressure limit for the internal electric
pump:
1. Press C then LIMITS and the limit setting is
displayed.
2. Use
Z to increase or Y the limit setting.
3. Press ENTER when finished.
When the calibrator power is cycled, the limit setting is
retained.
Note
To prevent pressure module damage, operation
of the internal electric pump is automatically
limited to the maximum rating of the module. For
1 inH2O, 10 inH2O and 1 psi modules, the internal
pump is disabled.
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. Pressure can be applied with the
Calibrator’s internal pump or with an external pump.
W 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 the
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 5. Figure 5 shows the internal pump
being used with a pressure module.
Note
If both a pressure module and the internal sensor
are connected, the Calibrator displays ONLY the
pressure module measurement.
Pressure Calibrator with Electric Pump
Using the Internal Pump
11
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 Zto 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. Press
P to apply pressure/vacuum.
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.
9. 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. Run pump for a few seconds.
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.
Using an External Pump
W Caution
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 5.
Make overall connections as shown in Figure 6.
Refer to setup and operating instructions included with the
