Instruction Manual
InstruTech CVM-211 "Stinger" Convection Vacuum Gauge Module
Module and Gauge Replacement
The CVM module is factory calibrated for the specific gauge tube installed in it. Since each gauge tube and
module calibration is different, the gauge cannot be replaced. If the gauge fails for any reason, the CVM-211
module must be replaced. Given the low cost of a new CVM-211 module, it is generally considered an
expendable item. If your module develops an electronic problem, and you want to return the unit to InstruTech for
repair, contact us for return authorization, as described below.
Factory Service and Support
If you need help setting up, operating, or troubleshooting your module, you are welcome to call us during normal
business hours (8:00am to 5:00pm Mountain time) Monday through Friday, at 303-651-0551. Or e-mail us at
info@instrutechinc.com
.
If it becomes necessary to return the unit to InstruTech for service or calibration, please call or
e-mail us for a return authorization number. For the safety of our employees, you must down load a material
disclosure form from our website at
www.instrutechinc.com
Please use this form to provide a history of the gauge
detailing what gases have been used. We cannot work on gauges that have been exposed to hazardous
materials.
