DTG Operation Manual

Introduction

Thank you for choosing the Digital Test Gauge (DTG) from Crystal Engineering

Corporation.

The DTG is very much like a mechanical test gauge:

Rugged, accurate, and easy to use. The difference,

of course, is the greater accuracy possible with

a digital display and, through an advanced

design, accuracy that is specified in percent

of reading over the entire operating

temperature range of -10°C (14°F) to

50°C (122°F).

The large LCD was designed to be

reliable and easy to see under a variety

of environmental conditions. The DTG

display is a full five digits (99999), so auto-

ranging is not required: There’s always

enough display resolution for the rated

accuracy.

The silicon chip pressure sensors used in all DTGs are

highly repeatable over pressure and temperature. DTG

sensors incorporate a permanently filled, oil isolated

stainless steel diaphragm in an all-welded fitting. The only

wetted materials are 316 stainless steel. Integral to the

process connection is a stainless steel filter, insuring that only gases or liquids reach

the sensor diaphragm.

Other features include:

• Select from up to 9 different pressure units (depending on pressure range)

• Minimum and maximum pressure detection

• Automatic shutdown after 20 minutes (shutoff can be easily disabled)

• 1500 hour battery life (continuous use) on 3 standard alkaline AA batteries

Long battery life while maintaining high performance is the result of using a RISC

(Reduced Instruction Set Computer) type microprocessor. The case is electro-

polished stainless steel with elastomeric seals, for weather and corrosion resistance.

And finally, the DTG is manufactured and serviced by a company that only makes

pressure measuring instruments. It’s the only thing we do and that’s why we say:

Pressure is Our Business!
