Overview 1 — Overview INTRODUCTION Thank you for choosing the WT Series Digital Test Gauge from Crystal Engineering Corporation. The WT Series is a combination of leading edge technology and rugged industrial design. The WT Series Digital Test Gauge is designed to fit in 8" or 10" panel mount applications commonly found in portable test sets. The WT Series is based on the Crystal Engineering Corp. model XP2i digital pressure gauge (www.xp2i.com).
— Overview 2 OPERATING INSTRUCTIONS The WT Series is shipped with batteries installed, so it’s ready to use. Press and hold the (on/off ) button. The WT Series will first test all LCD seg- ments. Release the (on/off ) button when the WT Series indicates pressure. The WT Series always resumes operation in the mode and the units of the pressure last used, and it does not automatically rezero when turned on. Connect the WT Series to your system.
Functions 3 Functions units Units Button Pressing this button causes the WT Series to select the next available unit of pressure measurement. See Pressure Ranges, Display Scales, & Resolution on page 14 or the list of pressure units available for your model. Units that you don’t need or never use can be turned off. You can also define a special unit for your WT Series with ConfigXP.
Functions 4 zero Resetting (Clearing) Recorded Peak Values clear Peak values can only be cleared when displaying either a Peak High or Peak Low recorded pressure. Press the (clear) 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 5 Automatic Shut-off The WT Series has a shutoff timer and will turn off automatically after 20 minutes of non-operation. Pressing any button or sending any command via the RS232 connection resets the shutoff timer for another 20 minutes of operation. The WT Series will briefly display Auto Off 20 when turned on. To disable the shutoff feature, turn on the WT Series by pressing the (on/off) and (zero) buttons simultaneously.
Functions 6 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 WT Series 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 WT Series can be set to use the density of water at 20° C (68° F) or 15.6° C (60° F) instead.
Functions 7 PSVtest Mode PSVtest mode is designed for PSV and PRV (“Pressure Safety Valve” and “Pressure Relief Valve”, respectively) as well as for Rupture Disc (also known as “Burst Disc”) testing. It increases the measurement rate of the WT Series gauge to approximately eight times per second, to capture the peak pressure when the valve opened, and adds a method of automatically capturing the closing reseat pressure. Use ConfigXP to activate PSVtest Mode.
Functions 8 Low Battery Indication The Battery icon ( ) uses three bars to display the battery level. When the icon displays all three bars, the batteries are full. The WT Series will continue to operate accurately while the icon is visible. When the batteries are exhausted, the letters batt will appear across the display. After batt appears, no pressure measurements will be possible until the batteries are replaced. Battery Replacement The WTSeries gauge uses 3 AAA alkaline batteries.

— Enclosure 10 SERIAL NUMBERS Serial Number Location The serial number of your WT Series is located on the front panel directly below the zero button. It is also stored digitally within the gauge. You may also find your serial number using ConfigXP software. See ConfigXP for more information. Serial Numbering System Serial Numbers consist of 6 numbers, with the left most digit representing the year of manufacture. For example: 267358 was manufactured during 2012.
Specifications 11 Specifications Accuracy 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 (if not an absolute model), rezeroed. To exercise a gauge, cycle the gauge between zero (ambient barometric pressure) and the pressure of interest.

Support 15 — Support TROUBLESHOOTING The XP2i is a very high performance gauge. Due to the high resolution of this product, you may observe conditions that appear to be defects in the product, but are in fact a result of being able to resolve and measure pressure to a degree not possible with other instruments.
— Support 16 CALIBRATION Factory Adjustment If adjustment is required, we recommend returning the unit to the factory. Factory service offers benefits you won’t find anywhere else. We have the facilities to test your gauge at a variety of temperatures utilizing NIST traceable standards in our A2LA accredited laboratory, resulting in calibration certificates that provide performance data over temperature. Furthermore, upgrades may be available to add or enhance operating features.
