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.
W
Warning
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
O
pushbutton 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:
1.
With the Calibrator OFF, press the
O
key.
P.S.xx
is
displayed, where
xx
is the turn-off time in minutes.
OFF
means the power saver is disabled.
Press
]
and/or
}
to increase or decrease the turn-
off time in minutes.
To disable, press
}
until the display shows
OFF.

HART
Resistor Mode
The calibrator has a user selectable 250 ohm HART
TM
resistor to
facilitate use with HART
TM
communication devices. The resistor
can be switched in/out at any time by simultaneously pressing
TM
the
V
and
A
keys. Use a HART 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:

Storing 0% and 100% Setpoints
Using the

controls set the output to the desired
output value for 0%.
