INTRODUCTION
Thank you for choosing the WT Series Digital Test Gauge from Crys tal En gi neer ing Corporation. The WT Series is a combination of leading edge tech nol-
o gy and rug ged in dus tri al de sign. The WT Series Digital Test Gauge is designed to  t 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). The WT Series 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).
Accuracy is 0.1 percent of reading
– so any WT Series can typically replace several gauges you may have been using. The WT Series is fully temperature compen-
sated
– so there is no change in accuracy through out the entire operating temperature range!
The WT Series’ case is made from rugged aluminum alloy utilizing a gasket to seal the enclosure against dust and water intrusion. Even the RS-232 connector
is fully sealed (with or without the red cover or rubber boot). Circuitry is mounted in shock absorbing elastomer supports and the batteries are easily acces-
sible by removing four screws. But you won’t need to change the batteries often, since 3 AAA batteries provide up to 500 hours of continuous operation. The
batteries are easily replaced by removing the two screws. Other features include:
•
Continuous capture of peak and valley pressure read ings
•
PSV mode
•
Programming interface
•
User-de ned units
•
All welded 316 stainless steel sensor
