Introduction The Calibrator features: The 719 30G and 100G Series Pressure Calibrators (the Calibrator) perform the following functions: • Precision air bleed for fine control • Fine vernier adjustment for the pump • Calibrate P/I (pressure to current) transmitters • A serviceable electric pump • Calibrate I/P (current to pressure) devices • Pressure limit settings • Identify the set, reset and deadband of of pressure switches • HART resistor mode • Measure pressure via a 1/8-in.
719 Series Users Manual The Calibrator makes 5-digit pressure measurements in the units shown below: • Psi • inH2O at 4 °C • inH2O at 20 °C • kPa • cmH2O at 4 °C • cmH2O at 20 °C • bar • mbar • kg/cm2 • inHg • mmHg For pressure modules, full-scale readings for all pressure ranges can be made in: • Psi • kPa • inHg To avoid display overflow, full scale readings are limited to 1000 psi in cmH2O, mbar, and mmHg units, and 3000 psi in inH2O units.
Pressure Calibrator with Electric Pump Introduction • • • • • • • • • • • Make sure the battery door is closed and latched before operating the Calibrator. Do not operate the Calibrator if it is damaged. Do not operate the Calibrator around explosive gas, vapor, or dust. When using probes, keep fingers behind the finger guards on the probes. Use only two 9 V batteries, properly installed in the Calibrator case, to power the Calibrator. Follow all equipment safety procedures.

Pressure Calibrator with Electric Pump Getting Acquainted with the Calibrator Getting Acquainted with the Calibrator The Calibrator displays pressure and current measurements simultaneously. See Table 2 and Figure 2 for front panel features. The upper display shows the applied pressure or vacuum (shown as a negative value). Press ENTER then UNITS to select a different unit. When the power is cycled off and on, the Calibrator retains the unit last selected.

719 Series Users Manual HART Resistor The Calibrator has a selectable 250 Ω HART resistor to facilitate use with HART communication devices. Use a HART communicator when measuring mA with loop power or sourcing mA. The HART resistor defaults to OFF. Switch Test To perform a switch test: To turn on the HART resistor: 1. With the Calibrator OFF, press O. 2. When HArt is displayed, press Vor U to turn on/off. 1. Power Saver The Calibrator automatically turns off after 30 minutes of inactivity.
Pressure Calibrator with Electric Pump Zeroing with Absolute Pressure Modules 3. 4. 5. 6. Press S to enter pressure switch test mode. The Calibrator will display CLOSE instead of a mA measurement. Apply pressure with the pump slowly until the switch opens. Note In the switch test mode, the display update rate is increased to help capture changing pressure inputs. Even with the enhanced sample rate, pressuring the device under test should be done slowly to ensure accurate readings.
719 Series Users Manual Set Maximum Pressure Limit Using the Internal Pump To set a maximum pressure limit for the internal electric pump: The internal pump can provide the rated pressure for the Calibrators. 1. Press C then LIMITS and the limit setting is displayed. 2. Use Z to increase or Y the limit setting. The preferred use for the internal pump is shown in Figure 4, where the Calibrator displays pressure measured with the internal sensor and provided by the internal pump. 3.
Pressure Calibrator with Electric Pump Using the Internal Pump To use the Calibrator’s internal pump, refer to Figure 3 and perform the following steps: 1. Depressurize and drain the line before connecting the Calibrator. 2. Connect the pressure transmitter to the Calibrator internal sensor as shown in Figure 4 (for internal pressure sensor measurements) or Figure 5 (for pressure module measurements). 3. 4. Note To avoid leaks, use Teflon tape or similar sealant on all pressure connections.

Pressure Calibrator with Electric Pump External Fluke Pressure Module Compatibility External Fluke Pressure Module Compatibility If inappropriate units are selected, the output of Fluke 700P Pressure Modules can cause the Calibrator display to overflow (OL), or displays values that are too low to be read. Refer to Table 6 for appropriate unit and range compatibility. Table 6.
719 Series Users Manual Supplying Loop Power mA Modes The Calibrator can supply loop power at 24 V dc to a current transmitter that is disconnected from the system. Use the following procedure: Different mA functions can be accessed by repeatedly pressing A: 1. With power off, hold down Z while pressing n. Loop Power appears in the display. 2.
Pressure Calibrator with Electric Pump Sourcing 4 to 20 mA Sourcing 4 to 20 mA Simulating a 4 to 20mA Transmitter To select current-sourcing mode, use the following procedure: Simulate is a mode of operation in which the calibrator is connected into a loop in place of a transmitter and supplies a known, settable test current. 1. Press A until Source is displayed. 2. Connect leads as shown in Figure 8. 3. Enter the desired current by pressing Z or Y. 1.
