•Introduction
Thank you for choosing the Vaetrix Test Gauge. Vaetrix is
engineered by individuals that have been in the process
control industry for well over twenty years. We take pride in
the fact that our products are designed and manufactured in
the USA. The gauge itself is backed by an industry leading
four-year warranty. Our products are designed and built to
take abuse. We would have it no other way.
The only way we can get better is by listening to you, the
customer. If you have any comments or suggestions feel free
to send us an email at [e-mail] or call at 888-797-
3740.
•Brief Overview
The gauge is powered by 3 AA alkaline batteries that provide
over 1000 hours of continuous use. To replace the batteries
just remove the screw located in the battery door or use a
coin for the HTGX Series. Communications for datalogging
and downloads is handed by USB. A standard USB to Micro B
cable will work for the HTG Series or A Standard USB to B for
the HTGX (printer-style cable). For further details on all
important measurement parameters consult the
specifications section in the manual.

•Admin –Reduce Resolution
The least significant digit will removed from the display
when selecting REDUCE RESOLUTION. This feature can be
useful for recording values and pulsating pressure if
damping is not used. Full resolution can be restored by

•Admin –Adjust Calibration
We recommend calibration on an annual basis. Calibration
frequency should be determined by your quality system
based on history, usage, and other key criteria.
Although we suggest you return the HTG to factory for
calibration, you can field calibrate the unit with trained
personnel and equipment traceable to the National Institute
of Standards and Technology (NIST). To begin the process
select ADJUST CALIBRATION.

The unit will prompt you to apply the high reference
pressure. We recommend that you are within 10% of the
high pressure reference setpoint. Enter in the known value

Follow the same steps for the low pressure reference
setpoint. Once again, we recommend you are with 10% of
the setpoint.
