TM

HART

An internal 250 Ω HART resistor can be enabled when
the Product operates in the mA Measure-24 V mode. This
lets a HART Communicator be connected across the mA
terminals. It is not necessary to add an external resistor.

Resistor

Note

When the HART resistor is on, the maximum

Ω

load-driving capacity is 750

.

Pump Limits

To prevent overpressure of sensitive devices, the
maximum pressure (pump limit) can be set. When in this
mode, use the arrow softkeys to set the maximum
pressure.

Initial Setup and Basic Pressure Generation

The Product is supplied with a special low-volume
calibration hose kit for faster pumping to pressure and
quick pressure stabilization. The necessary “quick-fit”
hose connectors and BSP adapter for non-NPT
applications are also included. Fluke recommends that
this type of hose be used to get the best performance
from the Product. When the fittings are installed and the
Product is connected to the unit under test (UUT), the
Product is ready. Figure 3 shows a typical setup.

1. Before pressure is generated, make sure the Product
is configured for the application. If necessary, review
the “Calibrator Interface” section to select the correct
configuration.

2. Make sure that the pressure vacuum knob is set for
the correct function (+ for pressure and – for
vacuum).

18

Pressure Calibrator

Initial Setup and Basic Pressure Generation

3. Close the vent knob.

4. Push the pump key and see the pressure (or
vacuum) increase until the necessary pressure is
reached.

Note

The pump motor speed will start slowly when
pressure is low (<15 psi) for better control at low
pressures.

Valve

Figure 3. Pump Connection

hix009.eps

5. Use the fine adjustment vernier to fine tune the
pressure/vacuum indication as necessary.

6. To fully decrease or bleed off the pressure, slowly
turn the vent knob to the open position. When this is
done carefully, the pressure-bleed rate can be
carefully controlled and this helps when taking down­scale pressure readings.

Users Manual

Electric Pump Considerations

The Product uses a small, battery-powered pneumatic
pump that can quickly build rated high pressure. Because
the pump has an upper pressure generation limit, there
may be atmospheric conditions where it cannot go to full­scale pressure. High-altitude use (about 3000 ft or
1000 meters), or use at cold temperatures, can limit the
pump to about 90 % of its rated pressure. In these cases,
the vernier adjustment can be used to supply additional
pressure necessary if full-scale pressure must be
supplied.

In these situations, start the calibration with the vernier in
the full counter-clockwise position and then, when the
electric pump reaches its limit, turn the vernier clockwise.
This will raise the pressure to set the necessary reading.
See Figure 3.

Measure Pressure

To measure pressure, connect the Product with the
correct fitting. Select a pressure setting for the display
that is used. The Product has one internal sensor and
many optional external sensors (EPMs) are available.
Make sure to choose the sensor based on working
pressures and accuracy.

Warning

To prevent personal injury:

• Pressure sensors can be damaged

and/or personnel injury can occur due to
improper application of pressure. Refer
to Table 9 for information on
overpressure and burst pressure ratings.
Vacuum should not be applied to any
gauge pressure sensor. The Product
display shows “OL” when an
inappropriate pressure is applied. If “OL”
is shown on any pressure display, the
pressure should be reduced or vented
immediately to prevent Product damage
or possible personnel injury. “OL” is
shown when the pressure exceeds 110 %
of the nominal range of the sensor or
when a vacuum in excess of 2 PSI is
applied on gauge range sensors.

• Push Z to zero the pressure sensor

when vented to atmospheric pressure.

Pressure Calibrator

Measure Pressure

Note

To ensure accuracy of the Product, the Product
must be zeroed before a device is calibrated.
See the “Zero Function Use” section.

Media Compatibility

The Product has a unique user-accessible valve cleaning
port for easy pump service. See the “Clean the Valve
Assembly” section for how to clean these valves. Make
sure to only expose the Product to clean, dry gases.

Measure Pressure with External Modules

The Product has a digital interface to be used with
external pressure modules. These modules are available
in different ranges and types that include gauge, vacuum,
differential, and absolute. Connect the modules to the
interface and select [EXT] (external sensor). Since the
interface between the Product and the module is digital,
all accuracy and display resolution is derived from the
module. See Figure 4.

Measure and Generate Current (4 mA to 20 mA)

Use the input terminals on the front of the Product to
measure current, see Figure 5:

1. Select the mA function on the lower display and
select MEASURE. Current is measured in mA and
percentage of range. The range on the Product is set
to 0 % at 4 mA and 100 % at 20 mA.

For example:

If the current measured is shown as 75 % then the
mA value is 16 mA.

Note

The display shows “OL” when the measured
current is more than the nominal range of
current measurement (24 mA).

2. To source current, the same connections are used.
From the configuration screen, select mA source or
mA Sim-2W.

3. This function will only work on the LOWER screen. In
the source mode, the Product supplies 0 mA to
24 mA with its own internal 24-volt supply, whereas
in the simulate mode the Product acts as a two-wire
transmitter and an external 24-volt supply is
necessary.

4. Push any of the arrow softkeys to start the output

Measure Temperature with an RTD

To measure temperature with an RTD probe, select the
RTD function on one of the displays. Make sure the
correct probe type is selected. See the “Set the RTD
Probe Type” section.

The standard probe has a 10-inch insertion depth with a
¼-inch diameter stainless steel sheath. See Figure 7.

Note

The factory default type is PT100-385 so if the
Product is used with the Fluke 720 RTD Probe
(pn 4366669), it is not necessary to set the
probe type. Connect the probe to the Product
and configure the display to read temperature.

The display shows “OL” when the measured
temperature is outside the nominal
measurement range of the RTD function (below

-40 °C or above 150 °C). If a custom probe is
used, enter the R0 and coefficients with the
serial interface (see the “Remote Operation”
section).

Maintenance

Clean the Product

Caution

To avoid damaging the plastic lens and case,
do not use solvents or abrasive cleansers.

Clean the Product with a soft cloth dampened with water
or water and mild soap.

Clean the Valve Assembly

Occasionally, the Product may not work properly due to
dirt or other contamination of the internal valve assembly.
Use the subsequent procedure to clean the valve
assembly. If this procedure does not correct the problem,
a repair kit can be ordered. See the “User-Replaceable
Parts” section.

1. With a small screwdriver, remove the two valve
retention caps located in the battery compartment
area (see Figure 12).

2. After the caps have been removed, gently remove
the spring and ring assembly.

3. Set aside the valve assemblies in a safe area and
clean out the valve body with a cotton swab soaked
in IPA (isopropyl alcohol).

4. Repeat the process several times with a new cotton
swab each time until there is no evidence of
contamination or dirt.

5. Operate the pump handles several times and
recheck for contamination.

6. Clean the O-ring assembly and the O-ring on the
retention caps with IPA and inspect the O-rings
closely for any damage or excessive wear.
Replacements are included in the repair kit, if
necessary.

7. Inspect the springs for wear or loss of tension. They
should be approximately 8.6 mm long in the relaxed
state. If shorter, they may not provide sufficient seal
tension. Replace if necessary.

8. Once all parts have been cleaned and inspected,
reinstall the O-ring and spring assembly into the
valve body.

9. Reinstall the retention caps and gently tighten each
cap.

10. Seal the output port and operate the pump to at least
50 % of capacity.
