Pressure Calibrator
Instruction Sheet
Introduction
The Fluke Model 716 Pressure Calibrator (hereafter called
"Calibrator") calibrates P/I (pressure to current) transmitters,
measures pressure via a Fluke 700 Series Pressure Module,
measures current up to 24 mA, and supplies loop voltage. The
Calibrator simultaneously displays pressure and current
measurements.
The Calibrator makes 5-digit pressure readings in the following
O at 4 °C, inH
O at 20 °C, kPa, cmH
O at 4 °C,
units: psi, inH

readings for all pressure ranges can be made in psi, kPa, and
inHg units. To avoid display overflow, full scale readings are
limited to 1000 psi in cmH
O, mbar, and mmHg units and

3000 psi in inH
O units. Pressures of at least 15 psi must be

measured for meaningful readings in bar and kg/cm
units.
Your Calibrator is supplied with a Flex-Stand™ holster, an
installed 9 V alkaline battery, one set of TL75 test leads, one set
of AC70A alligator clips, and this instruction sheet.
If the Calibrator is damaged or something is missing, contact the
place of purchase immediately. Contact your Fluke distributor for
information about accessories. See "How to Contact Fluke." To
order replacement parts or spares, see "Replacement Parts."

  • Page 1 Pressure Calibrator Instruction Sheet Introduction The Fluke Model 716 Pressure Calibrator (hereafter called “Calibrator”) calibrates P/I (pressure to current) transmitters, measures pressure via a Fluke 700 Series Pressure Module, measures current up to 24 mA, and supplies loop voltage. The Calibrator simultaneously displays pressure and current measurements.
  • Page 2: Safety Information

    Safety Information Use the Calibrator only as specified in this instruction 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.
  • Page 3: Explanation Of International Symbols

    Explanation of International Symbols The symbols in the table below are used on the Calibrator or in this instruction sheet. International Symbols Symbol Meaning Earth ground Fuse Battery Refer to this instruction sheet for information about this feature. Double insulated Conforms to relevant Canadian Standards Association directives.
  • Page 4: Getting Acquainted With The Calibrator

    Getting Acquainted with the Calibrator Press to turn the Calibrator on and off. The Calibrator displays pressure and current measurements simultaneously. See the figure below. The upper part of the display shows the applied pressure. Press to select a different pressure unit. When you cycle the power off and on, the Calibrator retains the pressure unit you last used.
  • Page 5: Pushbutton Functions

    Pushbutton Functions Pushbutton Function Press to select a different pressure unit. For higher pressure module inputs, inappropriate (out-of- range) units are not available. Press on while pressing to source loop voltage. Turns pressure reading damping on and off. With damping on, the display does not update as quickly.
  • Page 6: Calibrating A P/I Transmitter

    Zeroing with Absolute Pressure Modules For zeroing, adjust the Calibrator to read a known pressure. This can be barometric pressure, if it is accurately known, for all but the 700PA3 module. An accurate pressure standard can also apply a pressure within range for any Absolute Pressure Module. Adjust the Calibrator reading as follows: Press and hold Press...

    T E S T qo007f.eps Maintenance For maintenance procedures not described in this instruction sheet, or if the Calibrator needs repair, contact a Fluke Service Center. In Case of Difficulty • Check the battery, test leads, and pressure tubing. Replace as necessary.
  • Page 9 Calibrate your Calibrator once a year to ensure that it performs according to its specifications. A calibration manual is available (PN 686540). Call 1-800-526-4731 from the U.S.A. and Canada. In other countries, contact a Fluke Service Center. Replacing the Battery When the symbol appears on the display, replace the battery with a 9 V alkaline battery.
  • Page 10 Replacing the Fuse W Warning To avoid personal injury or damage to the Calibrator, use only a 0.125A 250 V fast fuse, ® Littelfuse 2AG. Fuse F1 is probably blown if the mA measurement display reading does not respond to current applied to the current (mA) inputs.
