After applying power, operate controlled equipment under normal conditions and use a reliable set of pressure gauges to verify that the transducer and the associated control are operating properly. 0.5 VDC to 4.5 VDC ratiometric versions The ratiometric versions of the P499 transducer receive a constant 5 VDC (nominal) supply voltage and vary the output signal voltage, based on the sensed pressure. The output voltage varies from 10% to 90% of the supply voltage, providing a 0.5 VDC to 4.5 VDC (nominal) signal. To verify that the transducer is working properly: 1.With the transducer in place and the controlled system pressure stabilized, measure the pressure at the transducer with an accurate and reliable gauge. This is the measured pressure (P). 2.Determine the maximum (P max ) and minimum (P min ) pressure values for the transducer’s pressure range. (See Table3, Table4, or Table5.) 3.Measure the voltage between Supply (red) wire and Common (black) wire. (See Figure3.) Use this in Step 3 as the measured supply voltage, V s . 4.Use the equation in Figure7 to determine the calculated output voltage for the ratiometric transducer. 5.Using your multimeter, measure the DC voltage between the transducer Output (white) wire and Common (black) wire. (See Figure3.) This is the measured output voltage. 6.Compare the calculated output voltage (Step4) and the measured output voltage (Step5). If the measured output voltage differs greatly from the calculated output voltage, replace the transducer. Note:It is normal for the transducer reading to differ somewhat from pressure gauge readings due to voltmeter and gauge tolerances, and other factors. 0 VDC to 10 VDC versions To verify that the transducer is working properly: 1.With the transducer in place and the controlled system pressure stabilized, measure the pressure at the transducer with an accurate and reliable gauge. This is the measured pressure (P). 2.Determine the maximum (P max ) and minimum (P min ) pressure values for the transducer’s pressure range. (See Table6.) 3.Use the equation in Figure8 to determine the calculated output voltage for the 0 VDC to 10 VDC transducers. 4.Measure the voltage between the transducer Output (white) wire and Common (black) wire with a multimeter set to measure DC voltage. (See Figure3.) This is the measured output voltage. 5.Compare the calculated output voltage (Step3) and the measured output voltage (Step4). If the measured output voltage differs greatly from the calculated output voltage, replace the transducer. Note:It is normal for the transducer reading to differ somewhat from pressure gauge readings due to voltmeter and gauge tolerances, and other factors. IMPORTANT:The P499 transducer is a precision sensing device and testing accuracy is typically beyond the capability of field diagnostic tools. IMPORTANT:The 0.5 VDC to 4.5 VDC ratiometric transducers are rated for 5.0 ±0.25 VDC, Safety Extra-Low Voltage (SELV) or Class 2. Exceeding the supply voltage rating can damage the transducer and void any warranties.

This is the measured pressure (P). 2.Determine the maximum (P max ) and minimum (P min ) pressure values for the transducer’s pressure range. (See Table7.) 3.Use the equation in Figure9 to determine the calculated output current for the 4 mA to 20 mA transducers. 4.Measure the P499 transducer output current. To measure the P499 Output current: Disconnect the P499 Output (black) wire from the control input terminal. Set your multimeter to milliamperes (mA). Then connect the multimeter’s red test-lead to the P499 Output (black) wire and the multimeter’s black test-lead to the control input terminal. The milliamperes (mA) reading on your multimeter is the measured output current. 5.Compare the calculated output current (Step3) to the measured output current (Step4). If the current from measured output current differs greatly from the calculated output current, replace the transducer. Note:It is normal for the transducer reading to differ somewhat from pressure gauge readings due to multimeter and gauge tolerances, and other factors.
