Page 4: Introduction
Introduction The WTSeries Digital Test Gauge is designed to fit in 8” or 10” panel mount applications common- ly found in portable test sets. The WTSeries is based on the Crystal Engineering Corp. model XP2i digital pressure gauge (www.xp2i.com). The WTSeries pressure gauge has been repackaged so that it may be mounted in a portable enclosure, while retaining easy access to batteries and to the digital (RS-232) interface (both of which would otherwise be on the back of the gauge). -
Page 5: Operating Instructions
Series • Page 3 Operating Instructions The WTSeries gauge is shipped with batteries installed, so it’s ready to use. Press and hold the on/off ) button. The gauge will first test all LCD segments. Re- lease the button when the gauge indicates pressure. The WTSeries gauge always resumes operation in the mode and the units of the pressure last used, and it does not automatically rezero when turned on. -
Page 6: Units Button
Page 4 • Series Units button Pressing this button causes the WTSeries gauge to select the next available unit of “Pressure Ranges, Display Scales & Resolution” for pressure measurement. See the list of pressure units available for your model. FIGXP PROGRAMMABLE Units that you don’t need or never use can be turned off. -

Page 8: Backlighting The Display
Page 6 • Series Backlighting the Display Pressing the (backlight) button instantly lights the display at maximum brightness, but to keep it on you need to hold down the button for 2 seconds. The display will flash briefly, indicating that it will stay on for 1 minute. If you press the button again, the backlight will go into a lower brightness setting to extend battery life, the display will again flash briefly, and remain on for 2 minutes. -
Page 9: Overpressure Conditions
Series • Page 7 Overpressure Conditions The WTSeries gauge will read pressure up to approximately 110% of the rated pressure range. Above 110% percent of the range the display will start flashing and the readings will not be reli- able. The zero function does not affect the point at which the display starts flashing to indicate overpressure, so depending on the zero value it is possible that the display can start flashing with- out the maximum pressure being displayed. -
Page 10: Troubleshooting
Page 8 • Series Troubleshooting The WTSeries gauge is a very high performance gauge. Due to the high resolution of this prod- uct, 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. -

Your quality system may require more or less frequent calibration, or your experience with the gauge, or operating environment may suggest longer or shorter intervals. Although we prefer that you return the WTSeries gauge to Crystal Engineering for calibration, ordinary recertification and/or adjustments may be performed by any qualified personnel with ap- propriate training and equipment. -
Page 12: Wt Series Serial Number
PROGRAMMABLE The userspan level can be viewed, set directly, and disabled by ConfigXP. WT Series Serial Number The serial number of your WTSeries is located on the front panel directly below the zero but- ton. It is also stored digitally within the gauge. -
Page 13: Specifications
Series • Page 11 Specifications Accuracy specifications are for one year, and include all effects of linearity, hysteresis, repeatability, and temperature within the specified operating temperature range. The gauge must be exercised and re-zeroed whenever exposed to significant changes in environ- mental conditions to achieve these specifications. -
