Introduction
The Fluke 709 Precision Loop Calibrator and 709H
Precision HART Loop Calibrator (the Product or the
Calibrator) can be used for installation, calibration, and
troubleshooting of field transmitters, valves, and other
control system components at process plants. Primary
functions are source and measure mA signals in the 0 mA
to 24 mA range. The Product can also produce 24 V dc loop
power.
The 709H includes HART communication functionality and
supports a select set of HART universal and commonpractice commands. The Product can be used as a loop
calibrator or basic function communicator.
Product functions include:
• Current measurement, sourcing, and a selectable 24 V
supply
• 30 V dc measurement
• Valve test capability
• A selectable HART 250 Ω loop resistor
• Output step and ramp

Users Manual
Product features include:
• Large backlit display
• Digital selection knob with selectable decade control for
easy data entry
• Interactive menus
• Communicator mode reads basic device information,
does diagnostic tests, and can be used to trim the
calibration of most HART-enabled transmitters.
Note
All figures in this Manual show the 709H.

• Use the Product only as specified, or the
protection supplied by the Product can be
compromised.
• Examine the case before you use the
Product. Look for cracks or missing
plastic. Carefully look at the insulation
around the terminals.
• Do not use test leads if they are damaged.
Examine the test leads for damaged
insulation and measure a known voltage.
• Do not use and disable the Product if it is
damaged.
• Do not use the Product around explosive
gas, vapor, or in damp or wet

Step and Ramp Operation
For step and ramp operation, the percent keys can be
used to set the milliamp output to 0 % of span, 100 % of
span, or step the output by 25 % of span.
Hands-free operation is possible with . Set the
Product to automatically and continuously step or ramp
the milliamp output from 0 % to 100 % and back.
The 100 % value is always 20 mA, but the 0 % value can
be 0 mA or 4 mA. This depends on how the mA span is
set. The 25 % step size is 5 mA or 4 mA accordingly.
To use the manual step function:
1. Use the Main menu to set the Product to source or
simulate current.
2. Push to set the output to 0 % of span.
3. Push to set the output to 100 % of span.
4. Push to step the output in 25 % of span
increments, from 0 % of span to 100 % of span and
back.
Automatic Step and Ramp
To use the automatic step and automatic ramp functions:
1. Use the Main menu to set the Product to source or
simulate current.
2. The Product has separate auto ramp and step times.
Use the menu to set the ramp or step time.
3. Push once to continually step the output from
0 % of span to 100 % of span and back in increments
of 25 % of span at the specified interval.
4. Push once more to go to auto ramp.
5. Push one of the percent keys, and twice, to turn
off the auto step and ramp.
6. Push twice to continually ramp the output from
0 % of span to 100 % of span over the specified
interval, and then back over the specified interval.
7. Push one of the percent keys or once more, to
turn off the auto step and ramp.

For all Main screen operation modes, except mA
Measure with 24V or Volts Measure, the operation
mode is set to mA Measure when you enter the HART
Comm. Menu.
The operation mode remains the same as the main
screen when it is Measure with 24V. If Volts Measure
was selected from the Main menu, the menu defaults to
communicator mode only and the 250 Ω resistor selection
shows n/a.
The 250 Ω resistor selection cannot be edited in

The mode and 250 Ω resistor settings must correspond to
how the test leads are connected before you connect.

HART Connect
The HART Connect function locates the HART device in
the loop. Before an operation with a HART device, the
device must be located on the loop. This is done by
polling all of the possible device addresses and selecting
a device from those addresses that respond to the
search.
If a HART protocol revision 5 or earlier device is found on
the loop, polling stops at poll address 15. If not found, the
Product continues to poll address 63. Polling stops after
10 devices are found on the loop.
If multiple devices are found on the loop, a tag list is
shown. From the list, select the correct device. If only one
device is found on the loop, it becomes the selected
device by default.
When a selected device is found, all relevant data is read
from the device and the operations described in the
“Function Select Menu” and “Device Setup and Data”
sections of this manual become available.
Polling Loop
The Polling Loop function searches the loop for HART
devices. This function starts immediately. The screen
changes to show the string of dots that is extended once

There are 9810 records available. Each data sample uses
one record. Each session uses two records for overhead
data that is common to all of the data samples in that
session. There can be from 1 to 99 sessions.
