Volt/mA Calibrator
Instruction Sheet
Introduction
The Fluke 715 Volt/mA Calibrator is a source and measurement
tool for 0 to 24 mA current loop testing and dc voltage from 0 to
20/25 V. The calibrator does not source and measure
simultaneously.
Your calibrator is supplied with a holster, a set of test leads, an
installed 9 V alkaline battery, and this instruction sheet.

Safety Information
Use the calibrator only as specified in this sheet, otherwise the
protection provided by the calibrator may be impaired.
A Warning identifies conditions and actions that pose hazard(s)
to the user; a Caution identifies conditions and actions that may
damage the calibrator or the equipment under test.
WWarning
To avoid possible electric shock or personal injury:
•Never apply more than 30 V between any two
jacks (terminals), or between any jack and earth
ground.
•Make sure the battery door is closed and
latched before you operate the calibrator.
•Remove test leads from the calibrator before
you open the battery door.
•Do not operate calibrator if it is damaged.
•Do not operate the calibrator around explosive
gas, vapor, or dust.
•When servicing the calibrator, use only
specified replacement parts.
Caution
Use the proper jacks, function, and range for your
measurement or output application.
Turning the Calibrator On
Press the green Opushbutton to turn the calibrator on and off.
For longest battery life:
•For mA output, use current simulate mode instead of source
mode when an external 24 to 30 V loop power supply is
available. (See Simulating a Transmitter.)
•Turn off the calibrator when not in use.
Auto Shut-Off (Power Saver) Feature
The Calibrator automatically turns off after 30 minutes of
inactivity. To reduce this time or disable this feature:

715 English Instruction Sheet
Page 4
1. With the Calibrator OFF, press the Okey. P.S.xx is
displayed, where xx is the turn-off time in minutes. OFF
means the power saver is disabled.
2. Press ]and/or }to increase or decrease the turn-
off time in minutes.
3. To disable, press }until the display shows OFF.
HART TM Resistor Mode
The calibrator has a user selectable 250 ohm HARTTM resistor to
facilitate use with HARTTM communication devices. The resistor
can be switched in/out at any time by simultaneously pressing
the Vand Akeys. Use a HARTTM communicator when
measuring dc mA with loop power or sourcing mA.
Span Check Feature
The calibrator allows the users to store 0% and 100% setpoints
for each output function. Once setpoints are stored, the span
check feature allows the user to quickly toggle back and forth
from 0% to 100% or to step in 25% increments.
Automatic step and ramp modes can be enabled while in the
span check mode by simultaneously pressing the ]}keys.
First select the desired output mode (V,mV or mA) then preceed
to store the setpoints:
1. Storing 0% and 100% Setpoints
2. Using the ]}controls set the output to the desired
output value for 0%.
3. Press the ]}scroll keys simultaneously to store
the 0% value.
4. Now using the ]}controls set the output to the
desired output value for 100%
5. Again, press the ]}scroll keys simultaneously to
store the 100% value.

Using the Current Output Modes
The calibrator provides current output in mA or percent display.
Percent is -25.00 to 125.00%, where 0% is 4 mA, and 100% is 20
mA.
In source mode, the calibrator supplies the current. In simulate
mode, the calibrator simulates a two-wire transmitter in an
externally-powered current loop.
Sourcing mA
Use source mode whenever you need to supply current into a
passive circuit such as a current loop with no loop supply. Insert
the test leads into the OUTPUT +and −mA jacks as shown
below.
Note
A path must exist for current to flow between the
OUTPUT +and −mA jacks, otherwise the display will
indicate an overload (OL) when you set an output value.
