process transmitter.
The Product supplies loop power at 26 V dc through an
internal series resistance of 250 Ω. The setting supplies
sufficient current for two or three 4-20 mA devices on the
loop.
When you use loop power, the mA jacks are dedicated to
measuring the current loop. This means that the SOURCE
mA, measure RTD, and measure Ω functions are not
available (see Table 10.)
Connect the Product in series with the instrument current
loop as Figure 20 shows. To supply loop power:
1. Push s for Setup mode.
Note
Loop Power, Disabled is highlighted.
2. Push and to select Disabled or Enabled.
3. Push .
4. Push the Done softkey. “LOOP” is shown on the
display when Loop Power is in operation.
The Product has a source pressure display function where
an external pressure hand pump is necessary. Use this
function to calibrate instruments where a pressure source or
differential pressure measurement is necessary. See
Figures 21 and 36 for information about that application.
Many ranges and types of pressure modules are available
from Fluke, see “Accessories”. Before you use a pressure
module, read its instruction sheet. The modules are different
in how they are used, zeroed, what types of process
pressure media are allowed, and accuracy specifications.
To use the source pressure display, see Figure 21:
Warning
To avoid a violent release of pressure in a
pressurized system, shut off the valve and
slowly bleed off the pressure before attaching
the pressure module to the pressure line.
Caution
To avoid mechanically damaging the pressure
module:
•Never apply more than 10 ft.-lb. of torque
between the pressure module fittings or
between the fittings and the body of the
module.
•Always apply correct torque between the
pressure module fitting and connecting
fittings or adapters.
•To avoid damaging the pressure module
from overpressure, never apply pressure
above the rated maximum printed on the
pressure module.
•To avoid damaging the pressure module
from corrosion, use it only with specified
materials. See the printing on the pressure
module or the pressure module instruction
sheet for the acceptable material
compatibility.
1. Connect a pressure module and pressure source to the
Product as Figure 21 shows. The threads on the
pressure modules accept ¼ NPT fittings. Use the
supplied ¼ NPT to ¼ ISO adapter if necessary.
2. If necessary, push for SOURCE mode.
3. Push p. The Product automatically senses which
pressure module is attached and sets its range
accordingly.
4. Zero the pressure module as described in the module’s
instruction sheet. The module types are different in how
they are zeroed. The pressure module MUST be
zeroed before doing a task that sources or measures
pressure.
5. Pressurize the pressure line with the pressure source to
the necessary level as shown on the display.
6. If necessary, change the pressure display units to psi,
mHg, inHg, inH
O@60°F. Metric units (kPa, mmHg, etc.) are shown
inH
2
in Setup mode in their base units (Pa, mHg, etc.).
To change the pressure display units:
See “Temperature Measurement” for a table of
thermocouple types that are supported by the
Product.
Connect the Product TC input/output to the instrument
under test with thermocouple wire and the correct
thermocouple mini-connector (polarized thermocouple plug
with flat, in-line blades spaced 7.9 mm (0.312 in) center to
center).
Caution
To prevent possible damage to the Product, do
not try to force a miniplug in the wrong
polarization. One pin is wider than the other.
Figure 19 shows this connection. To simulate a
thermocouple:
1. Attach the thermocouple leads to the correct TC
miniplug, and then to the TC input/output. See Figure
15.
2. If necessary, push for SOURCE mode.
3. Push t, and then push to select the TC sensor
type. The display asks you to select the thermocouple
type.
4. Push or followed by to select the necessary
thermocouple type.
5. Push or followed by to select Linear T
(default), or Linear mV, (to calibrate a temperature
transmitter that responds linearly to millivolt inputs).
6. Record the temperature to simulate as prompted by the
display and push .
Note
If you use copper wire instead of thermocouple
wire, the reference junction is no longer inside the
Product. The reference junction moves to the
instrument (transmitter, indicator, controller, etc.)
input terminals. The external reference
temperature must be measured accurately and
recorded into the Product. To do this, push
and set Ref. Junc. Compensat. and Ref. Junc. Temp.. After you record the external reference
temperature, the Product corrects all voltages to
adjust for this new reference junction temperature.
See Table 8 for data about RTD (ResistanceTemperature Detector) types compatible with the
Product.
Connect the Product to the instrument under test as shown
in Figure 23. The figure shows connections for two, three, or
four-wire transmitters. For three or four-wire transmitters,
use the 4-inch long stackable jumper cables to connect the
third and fourth wires at the source V Ω RTD jacks.
To simulate an RTD (Resistance-Temperature Detector):
1. If necessary, push for SOURCE mode.
2. Push t.
3. Push or to select RTD.
4. Push . The Select RTD Type display is shown.
5. Push or followed by to select the necessary
RTD type.
6. The product tells you to use the keypad to enter the
temperature to simulate. Input the temperature, and
then push .
The Product can source temperature using a Hart Scientific
Drywell. Many models are supported.
The drywell driver is able to talk to other drywells from Hart
Scientific, provided that they respond to Hart Scientific’s
standard serial interface commands.
Connect the Product to the drywell by plugging the drywell
interface cable into the pressure module connector as
shown in Figure 24. If the drywell has a DB9 connector, plug
the drywell interface cable directly into the drywell using the
DB9 Null Modem adapter. Drywells with the 3.5 mm jack
connector need to use the serial cable supplied with the
drywell in addition to the Product drywell interface cable.
Join the DB9 connectors of the two cables, and connect the
3.5 mm jack to the drywell.
Be sure the drywell is configured for serial communication at
2400, 4800, or 9600 bits per second. Other rates are not
supported by the Product.
To source a temperature with a drywell:
1. If necessary, push for SOURCE mode.
2. Push t to display the temperature mode menu.
3. Select Drywell from the list of options, and press .
4. The Product will begin to search for a drywell. If the
Product shows Attempting connection for more than
10 seconds, double check your cable connections and
drywell configuration.
5. If a dual well is recognized, a menu will pop up that
allows you to select a "hot" or "cold" side of the dual
well. Only one side of the drywell may be controlled at a
time. Switching sides requires the drywell to be
reconnected, by disconnecting the serial cable or by
leaving drywell source mode and selecting it again.
6. When the drywell is connected, the primary display will
show the actual temperature of the drywell, as
measured by the drywell internally. The drywell model
number will appear above the primary reading. The
setpoint for the drywell is displayed in the secondary
display, at the bottom of the screen. Initially, the
setpoint will be set to the value already stored in the
drywell.
7. Enter the temperature you wish to source and press
.
The settled indicator will be cleared when the actual
temperature is within one degree of the setpoint, and the
actual temperature is not changing quickly. Refer to the
drywell documentation for that model's recommendations for
stabilization time.
The upper temperature limit is restricted by the "High Limit"
setting stored in the drywell. If the Product will not set the
drywell to temperatures within the drywell spec, refer to the
drywell manual to check the "High Limit" setting.
When the Product is set to display temperatures
in Kelvin, the drywell readout will show Celsius,
and when the Product shows Rankine, the
drywell will show Fahrenheit.

value (100% Value).
Square root percent of scale is in effect until the Product
is changed to a different source function or the Scale
softkey is pushed and you select a different scale mode.
Step and Ramp the Output Value
Two features are available that let you adjust the value of
source functions, except pressure. For pressure, an
external pressure source must be used:
•Step the output manually with and , or in
automatic mode.
•Ramp the output with optional continuity or V trip
detect.
Manual Step Use
The manual Step feature selects a step size in
engineering units (mV, V, mA, °C, etc.) or % of scale.
Step the output in % of scale to quickly jump between 0 %
and 100 % (set step size = 100 %) or 0-50-100 % (set
step size = 50 %). Step works in SOURCE and in
MEASURE/SOURCE modes.
To select a step size:
1. See the applicable Source Mode subheading in this
manual (for example, “Source Electrical Parameters”)
and connect the Product to the test circuit.
2. If necessary, push for SOURCE mode.
3. Set the Product for the necessary source value.
4. To step the source value in % of scale, set the % of
scale value as given before in “Measurement Scale”.
5. Push the Step softkey.
6. Use the numeric keypad to record the step size in the
units shown on the display.
7. Push the Done softkey.
8. Push and to adjust the output in steps.
Auto Step Use

• End point
• Number of steps
• Time per step
• Repeat mode, single shot or continuous
repetition
• Step style, Sawtooth or Triangle pattern
• Start delay
Push the Start Step softkey to automatically start the
step function. The softkey label changes to Stop Step.
8. To Push the Stop Step softkey to stop the automatic
step function.
9. Push the Done softkey to continue normal operation.
Ramp the Output
When ramped, the source sweeps up or down in value.
Use the ramp feature to check a switch or alarm, or when
a smooth increase or decrease of the output function is
necessary. The Product can be set to ramp up or down in
engineering units (mV, V, mA, °C, etc.) or % of scale.
While the signal ramps, the output is adjusted 4 times per
second. The size of the steps is bound by the selection of
endpoints and ramp time. For example, if you set the
Product to ramp from 1 mV to 1 V over 10 seconds, the
output is adjusted in approximately 25 mV steps.
The Ramp function continues until you get the selected
limit, or until an optional trip condition is met. The optional
trip detect works as follows: during ramping, the Product
checks for either a 1 V change in dc voltage or a change
in continuity status (Open or Short) from one ¼ second
interval to the subsequent interval.
1. See the applicable section earlier in this manual (for
example, “Source Electrical Parameters”) and
connect the Product to the test circuit.
2. To automatically stop the Ramp function if a trip
condition is sensed, connect a voltage trip circuit to
the V MEASURE jacks or a continuity trip circuit to
the mA Ω RTD MEASURE jacks. (Continuity
detection is not available when sourcing current.)
3. If necessary, push for SOURCE mode.
4. Set the Product for the necessary source value as
given before.
5. To Ramp the output in % of scale, set % of scale as
given before under “Measurement Scale”.
6. Push the More Choices softkey.
7. Push the Ramp softkey. The display changes to the
screen shown Figure 25.
8. Record the parameters given. Record the Start Value, End Value, and Ramp Time.
9. To automatically stop the Ramp function if a trip
condition is sensed, set the Trip Detect to Enabled,
and select Voltage or Continuity as the trip function.

Table 9 shows the functions that can be used at the same
time when Loop Power is disabled. Table 10 shows the
functions that can be used at the same time when Loop
Power is enabled.
Step or Auto Step features can be used to adjust the
output in MEASURE/SOURCE mode, or use the calibration
routine given when the As Found softkey is pushed.
Use the two softkeys shown in MEASURE/SOURCE mode
when you calibrate a process instrument:
•As Found, which can be used to set up a calibration
routine to get and record as found data.
•Auto Step, which can be used to set up the Product for
auto-stepping, as given before.

Process Instrument Calibration
Note
To calibrate a HART-capable transmitter using the
built-in HART interface, see the 754 HARTMode
Users Guide for instructions.
When the Product is in MEASURE/SOURCE, a built-in
calibration routine can be configured when the As Found
softkey is pushed. As Found data is the test results that
show the condition of a transmitter before it is adjusted. The
Product can run preloaded tasks that are developed with a
host computer and DPCTrack2 application software. See
“Communication with a PC”.
Generate “As Found” Test Data
The subsequent example shows how to supply as
found data for a thermocouple temperature transmitter.
Here, the Product simulates the output of a thermocouple
and measures the current regulated by the transmitter.
Other transmitters use this same procedure. Go back to
MEASUREMENT or SOURCE mode and change the
operation parameters before you push As Found.
1. Connect the test leads to the instrument under test as
shown in Figure 30. The connections simulate a
thermocouple and measure the corresponding output
current.
2. If necessary, push for MEASURE mode.
3. Push .
4. Push for SOURCE mode.
5. Push t and to select TC sensor.
6. Push and to select the thermocouple type.
7. Push to select then to select Linear T source
mode.
8. Record a source value, for example 100 degrees, and
then push .
12. More delay time can be input for the process instrument
to become stable than the Product’s usual settling time
(about 2 seconds). To change the delay time, input that
time in seconds for Delay.
13. Push and to move the cursor down to record 0%
and 100% values for SOURCE temperature. Our
example uses 100 °C and 300 °C.
14. If the instrument calibration procedure requires you to
manually record the measurement value or source,
push the User Value softkey, for user-recorded values.
Custom Units lets you specify user units such as PH.
See “Creating Custom Measurement Units”, given
before in this manual for an example.
When you use custom units, is shown next to the
value on the display and in results.
Push the Done softkey after the custom unit has been
programmed.
15. The Test Strategy is the number of test points and
which test points are performed rising and falling in
percent of scale. This example uses five points (0 %,
25 %, 50 %, 75 %, and 100 %), rising only. Rising is
indicated by the up arrow on the display. Push to
change to a different test strategy on this line. A list of
strategies is shown from which to choose. Select one,
and then push the Done softkey.
16. When you are done recording the calibration
parameters, the display should change to the screen
shown in Figure 31.
Documenting Process Calibrator Process Instrument Calibration
17. Push the Done softkey to accept the calibration
parameters. The display changes to the screen shown

18. At this time you can do an automatic test or step
through the test points manually. Push the Auto Test
softkey to have the Product go through the tests
automatically. If necessary, push Abort to exit from the
calibration procedure. The tests start at the first test
point, sources the correct temperature and measures
the corresponding current from the transmitter.
When a measurement is stable and recorded, the
Product goes to the subsequent step. Because the
Product waits until the measurement becomes stable,
the Auto Test works as necessary for instruments with
built-in damping. The error of the expected measured
value is shown in the top left of the measure window.
19. The Product moves to the remaining set of points. For
temperature and electrical parameter calibration, the
points are done automatically. If your source pressure,
the Product stops at each step to let you adjust the
pressure source. When the tests are complete, an error
summary table similar to Figure 33 is shown.
In the results summary test, failures are highlighted. An
adjustment is necessary in this example because three
tests show failures. The failures were outside the
±0.5 % tolerance that was selected.
20. Push the Done softkey to keep the data, or the Abort
softkey to erase the data and start again.
See the data entry that was recorded and recall the
table later with the Review Memory softkey during
normal operation. This data can be uploaded to a host
computer that runs compatible DPCTrack2 application
software. See “Communication with a PC”.

Log Data
Users can record a series of measurements for later upload
to a host computer that uses DPCTrack2 application
software. See “Communication with a PC”. Up to 8000
readings can be recorded, depending on the reading rate,
duration, and how much memory is being used for other
things such as tasks or kept results. Record the reading rate
and duration in minutes. See Figure 40.
4. A list is shown; select a reading rate (1, 2, 5, 10, 20, 30,
or 60 readings per minute). Push or to select the
reading rate.
5. Push .
6. Push to move the cursor to Duration.
7. Use the numeric keypad to record the duration in

assuming that no memory is being used for other purposes.
To prevent possible damage to the Product,
use a completely charged battery and the
appropriate duration, or use the battery charger
to avoid losing power during a logging
session. If a low-battery condition occurs
during a log session, the session is terminated
and data collected to that point is kept. A long
logging duration can exceed the life of a
battery charge.
8. After the Product records the duration selection, the
display shows how much memory that duration will
consume. See the Memory Available percentage on
the display. Memory Available indicates the

the normal display. Figure 42 shows the display with Min
Max on.
Push the More Choices softkey until the Tasks softkey is
shown, then push Tasks to see the list of tasks
(procedures) downloaded from a host computer. Tasks are
Product configurations, kept with a procedure name, for
example the type and manufacturer of a specific transmitter.
A task configures the Product for transmitter calibration with
all the calibration parameters (source and measure
functions, 0% and 100% levels, test strategy) predefined.
While the task controls the Product, the Continue softkey
becomes Continue Task.
Clear the Memory
In Setup mode, highlight the Clear Memory choice and
push to erase the memory:
• Results that have been kept
• Min Max data
• Log data sets
A confirmation message is shown so that the memory is not
accidently erased.
The Calculator
For mathematical equations that involve the Product’s
source or measured value, use the Product’s built-in
calculator. The current measure and source values and
units, are always available to be put into an equation with
one keystroke. The Product measures and sources during
calculator operation.
Push the Calc softkey to start the calculator from the
SOURCE, MEASURE, or MEASURE/SOURCE mode. Push
the More Choices softkey to see the Calc softkey if
necessary.
After you push Calc, the display, number keys, and keys
with calculator functions (, , , , r and )
become an algebraic-entry calculator.
Push the Done softkey to start normal Product operation.
When the Product is in calculator mode, the top half of the
display shows three register names and their contents:
• MEASURE (the present measured value)
• SOURCE (the present sourced value)
• REGISTER (temporary storage for your use)
Push the Recall softkey and then the softkey for the
applicable register to insert the contents of any register into
a calculation.
Push Store to copy the number from the calculator display
(lower half) into REGISTER to temporarily save the number
for later use, or into SOURCE.
Use the Calculator to Set the Source Value
When you store to SOURCE, the Product shows a selection
of unit multipliers when necessary (for example, mV or V),
then starts sourcing that value. The Product will not keep
out-of-range values to SOURCE.
