Overview OPERATING INSTRUCTIONS The XP3i is shipped with batteries installed, so it’s ready to use . Press the button . The XP3i will first test all LCD segments, and then indicate on/off pressure . The XP3i always resumes operation in the mode and the units of the pressure last used, and it does not automatically rezero when turned on.
Functions Functions Units Button Pressing this button causes the XP3i to select the next available unit of pressure measurement . Pressure Ranges, Display Scales, & Resolution on page 22 or the list of pressure units available for your model . Units that you don’t need or never use can be turned off .

Functions Resetting (Clearing) Recorded Peak Values Peak values can only be cleared when displaying either a Peak High or Peak Low recorded pressure . Press the zero button for at least ½ second . Dashed lines will briefly appear across the display indicating that both Peak values have been cleared . Both Peak High and Peak Low values will then display the current applied pressure .

Functions Tare ( -DD, Dual-Line Display XP3i Only ) Tare is a constant value subtracted from the true pressure . For instance, if you were mixing gases by partial pressure, you might want to fill a tank to 1760 psi with air, then add another 440 psi of helium .

Functions Automatic Shut-off The XP3i has a shutoff timer and will turn off automatically after 20 minutes (or the time set in CrystalControlWeb) of non-operation . Pressing any button or sending any command via the USB port resets the shutoff timer for another 20 minutes of operation . The XP3i will briefly display Auto Off 20 when turned on .

Functions Water Density (Inches of Water) The following applies only to models where inches of water is a selectable pressure unit . As shipped from the factory, the XP3i is set to display inches of water corresponding to the density of water at 4° C (39 .2° F) . You may require a different water density for your application, so the XP3i can be set to use the density of water at 20°...

Functions CrystalControlWeb software . Calibration Reminder Alert Cal Soon Enter the Cal Due date and the notification time prior . Once the defined time prior is reached, the XP3i will flash three times during the startup pro- cess . It will do this on every start-up until the calibration due date is reached, or the dates are updated . Calibration Due Alert Once the calibration due date has been reached, the XP3i has three options to choose from .

Functions Battery Replacement The XP3i uses 3 AA batteries . Loosen the four rear panel screws to gain access to the battery compartment . These four panel screws are captive inside the panel and are not remov- able . The foam gasket material inside the battery cover used to secure the batteries can make removal of the cover difficult . After all four screws have been loosened, the cover can be easily removed by prying gently on the hanging bracket with a flat head screwdriver or similar tool .
Data Logging with DataLoggerXP Data Logging with DataLoggerXP WHAT IS DATALOGGERXP? DataLoggerXP is an optional data logging mode available for the XP3i gauge . You may purchase the DataLoggerXP option with your original order or add it later .
Data Logging with DataLoggerXP XP3I DATALOGGERXP GAUGE OPERATION When in data logging mode, some of the standard functionality of the standard XP3i is suspended . This includes the ability to change units . Please ensure you have the correct units selected prior to entering data logging mode .

Data Logging with DataLoggerXP Keypad Usage The following buttons and button combinations are used to control data logging runs on the XP3i . Where two keys are indicated, the operation is executed by pressing and holding down the first key, then pressing and holding down the second key until the action is completed . Note: Start by turning off the gauge .
Page 15
Data Logging with DataLoggerXP Units Pressing and holding the button briefly causes the XP3i to display information about the logging state . If you continue to hold the button, a units units logging run will begin or end . Immediately after pressing the button, the gauge will display the operating mode as one of these values: units The XP3i is currently logging data .

Data Logging with DataLoggerXP Ultra Low Power (ULP) Mode The XP3i can log for extended periods with Ultra Low Power Mode, activated by the key combinations explained in Keypad Usage on page 12. Ultra Low Power Mode takes readings in Actual Mode when the recording interval is 20 minutes or longer . The letters replace the live pressure reading during a recording .
Data Logging with DataLoggerXP CRYSTALCONTROLWEB While the XP3i collects and stores the data, the CrystalControlWeb cloud software provides the interface to manage, analyze, download, and store the reports . Upload stored data from the XP3i to CrystalControlWeb (CCW) is done in one of two ways: Through Device Agent Connect to the XP3i with a standard USB cable .
Data Logging with DataLoggerXP BLUETOOTH SIGNAL The XP3i’s Bluetooth signal has been optimized to be most effective directly in front of the gauge . With a direct line of sight in front of the gauge, distances of over 100 feet are possible .
Specifications Specifications Accuracy – Gauge Pressure Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year . Gauges must be exercised whenever exposed to significant changes in environmental conditions to achieve these specifications, and then re-zeroed . To exercise a gauge, cycle the gauge between zero (ambient barometric pressure) and the pressure of interest .

Specifications Accuracy – Absolute Pressure Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year . Gauges must be exercised whenever exposed to significant changes in environmental conditions to achieve these specifications . To exercise a gauge, cycle the gauge between zero (ambient barometric pressure) and the pressure of interest .
