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).
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.
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.
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.
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
mode and use the arrow softkeys to adjust the mA
output. The function keys can also be used to step
the output in either 25 % steps (4, 8, 12, 16, 20 mA)
or 0 % (4 mA) and 100 % (20 mA). While in the mA
output mode, if the loop is opened or the compliance
is exceeded the display flashes “OL”.
To measure voltage, use the input terminals on the front of the Product. Select the volts function on one of the displays. The
Product can measure a maximum of 30 V dc. See Figure 6.
Note
The display shows “OL” when the measured voltage is more than the nominal range of the voltage measurement
(30 V).
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).
Connect a pressure switch to the Product as shown in
Figure 8.
Pressure
Switch
Use low volume tubing when possible
hix017.eps
Figure 8. Pressure Switch Connection
To do a pressure switch test:
1. Change the setup to Setup 4 (default switch test)
listed under “Setups” in the MORE configuration
menu choices. The upper display is set to [P1] ST, all
other displays are off.
Note
The pressure switch test can be done with these
functions: [P1] ST, or EXT ST.
Use low-volume tubing when possible.
2. Connect the Product to the switch with the pressure
switch terminals to the pressure switch contacts (deenergized dry contacts). The polarity of the terminals
does not matter. Connect the pump from the Product
to the input of the pressure switch.
3. Make sure the vent on the pump is open.
4. Zero the Product if necessary.
5. Close the vent after the Product is zeroed. If a
normally closed switch, the top of the display shows
“CLOSE”.
6. Apply pressure with the pump slowly until the switch
opens.
In switch-test mode the display update rate is
increased to help capture pressure input
changes. Even with this enhanced sample rate,
pressurization of the device under test should be
done slowly to ensure accurate readings.
7. When the switch is open, “OPEN” is shown on the
display. Bleed the pump slowly until the pressure
switch closes.
hix043.eps
At the top of the display “SW OPENED AT” and the
pressure that the switch was opened at is shown as in the
figure below.
8. Push the “NEXT” option to view when the switch
closed, and the deadband as seen below.
9. Push to clear the data and do another test.
10. Push to end the test and return to the standard
pressure setting.
Example:
[P1] ST will return to [P1].
Note
The previous example uses a normally-closed
switch. The basic procedure is the same for a
normally-open switch. The display reads “OPEN”
instead of “CLOSE”.
The mA input function reads back the 4 mA to 20 mA
output from the device being calibrated. This can be done
in one of two ways:
1. Passively – Where the device under test directly
regulates or generates 4 mA to 20 mA and can be
read by the Product.
hix047.eps
2. Actively – Where the Product supplies 24 V dc loop
power to the device under test to power the device
while reading the resulting 4 mA to 20 mA signal.
To calibrate a pressure-to-current transmitter (P/I):
1. Connect the Product and the pump to the transmitter.
See Figure 9.
2. Apply pressure with the pump.
3. Measure the current output of the transmitter.
4. Ensure the reading is correct. If not, adjust the
transmitter as necessary.
Note
Use low-volume tubing when possible.
Percent Error Function
The Product features a unique function which can
calculate pressure vs. milliamp error as a percentage of
the 4 mA to 20 mA loop span. The percent error mode
uses all three screens and has a unique menu structure.
It simultaneously shows pressure, mA, and percent error.
See Figure 10.
A pressure transmitter under test is 30 psi (2 Bar) FullScale and regulates a corresponding 4 mA to 20 mA
signal. Program a 0 psi to 30 psi pressure span into the
Product and the Product calculates and shows the
deviation or %Error from the expected 4 mA to 20 mA
output. This eliminates the need for manual calculations
and helps when it is difficult to set an exact pressure with
an external pump.
To use the %ERROR function:
1. From the Main Menu, push .
2. Push .
3. Push to start the %ERROR option.
4. Push to configure the option. The first option sets
the Port.
5. Push to scroll through the port choices.
6. When finished, push .
7. Loop Power can be toggled on/off as seen below.
Push when done.
The 0 % and 100 % point will be saved in nonvolatile memory until they are changed again by
the user for the internal sensors, and external
pressure modules. When an external module is
used, the 0 % and 100 % are set to low and full
scale of the module until the user changes it, or
if it was previously saved.
hix054.eps
Minimum and Maximum Storage
Capability
The Product has a min/max feature to capture the
minimum and maximum values of any displayed
parameter.
Step through the menu options to access the min/max
function. “MIN/MAX” is shown on the display above .
Push to toggle the display through the min/max values
that are stored in the min/max registers. These readings
are live so that the new min/max values will be recorded
while in this mode.
To reset the min/max registers, push for “CLEAR”.
These registers are also cleared at power-up or when the
configuration is changed.
Factory Setups
The Product is loaded with five commonly used factory
setups. To access these SETUPS, select from the MORE
configurations options. These setups are shown below.
Note
Any of these setups can be changed and saved.
Setup 1: The upper display is set to [P1] mode and the
lower is set to mA, middle is off.
The Product is ideal for flow computer calibration. Every
manufacturer of flow computers has a different calibration
procedure, but most call for calibration of three
parameters: static pressure, differential pressure and
temperature. To facilitate these measurements, recall
setup #5 on the Product.
1. Connect the Product to the static and differential
pressures. ([P1], EXT) Then connect the RTD sensor
to the Product.
2. With the reading of the RTD, static, and differential
pressures, make sure the flow computer has the
correct reading. If not, adjust the flow computer as
necessary.

Error Queue
If an error occurs due to invalid input or buffer overflow,
its error code is sent to the error queue. The error code
can be read from the queue with the command FAULT?.
The error queue holds 15 error codes. When it is empty,
FAULT? returns 0. The error queue is cleared when
power is reset or when the clear command *CLS is
entered.
Input Buffer
The Product stores all received data in the input buffer.
The buffer holds 250 characters. The characters are
processed on a first in, first out basis.
Commands for the Product may be entered in upper or
lower case. There is at least one space required between
the command and parameter, all other spaces are
optional. Almost all commands for the Product are
sequential. Any overlapped commands are indicated as
such. This section briefly explains each of the commands
and describe their general use, which include any
parameters that may be entered with the command as
well as what the output of the command is.
Common Commands
*CLS
Clears the error queue. Also terminates all pending
operations. When programs are written, use before each
procedure to avoid buffer overflow.
*IDN?
Returns the manufacturer, model number, serial number,
and firmware revision of the Product. For example:
Use this command to entere a custom RTD into the

in the current engineering units.
For example:
To set the 0 % point to 20 psi, send LO_ERR 20.
LO_ERR?
Returns the 0 % point for the percent error mode
calculation.
For example:
If the 0 % point is set to 20 psi, LO_ERR? returns
Returns the pump limit. The above example with
PUMP_LIMIT? returns:
50.000
REMOTE
Puts the Product into remote mode. From the remote
mode, the keypad can be used to get back to local mode
unless the command LOCKOUT was entered before
REMOTE. Then the keypad is locked out, and the LOCAL
command must be sent to get back to local operation.

Warning
To prevent possible electrical shock, fire, or
personal injury:
•Remove the batteries if the Product is
not used for an extended period of time,
or if stored in temperatures that exceed
the battery manufacturer’s specification.
If the batteries are not removed, battery
leakage can damage the Product.
•Replace the batteries when the low
battery indicator shows to prevent
incorrect measurements.
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.
11. Release the pressure and repeat several times to
ensure that the rings seat properly.
To prevent possible electrical shock, fire, or
personal injury, use only specified
replacement parts.
User-replaceable parts are listed in Table 10 and shown
in Figure 13. For more information about these items,
