Calibration is all about confidence in your results. Every new Vibration Research controller arrives freshly calibrated with a Certificate of Traceable Calibration to NIST. Annual calibration verification is your prescription for the continued health and performance of your controller.

Calibration Options

Calibration assures you that your measurements are accurate within the specification limits. Vibration Research recommends an annual calibration verification for vibration controllers and dynamic signal analyzers. The following three calibration options are valid for:
VR8500 | VR9500 | VR10500 | ObserVR1000

Product stack with ObserVR1000, VR9500 and VR10500

Option 1: Send to Vibration Research


Vibration Research puts your equipment through the industry’s most thorough calibration evaluation. The rigorous testing is performed by our experienced engineers.

A secondary key takes the place of your main unit hardware while it is shipped off for calibration (for customers with a current Upgrades & Support Agreement U&SA).



Our calibration plan delivers confidence while supporting your business needs for a fixed cost of ownership. As calibration is essential over the life of your equipment, plans are discounted when purchased with an active U&SA or if multiple units are calibrated at once.

Receive a 50% discount on all units when you send yours in for calibration. The discounted unit is shipped to your facility and helps to reduce downtime (option available if U&SA current).

Vibration Research is accredited by A2LA to ISO/IEC 17025:2017 and ANSI/NCSL Z540-1-1994. View our scope of accreditation.

Option 2: Calibrate With VR Software

Perform calibration verification in the lab using your calibration instruments and Vibration Research’s Automated Calibration Verification (VR95-CALxx) software license. Vibration Research wrote the Automated Calibration Verification software to automate the verification process. The automated procedure provides data and pass/fail information along with a certificate and a final report.

Connecting a VR9500 to a Digital Multimeter as part of calibration verification


  • If using a serial port to USB adapter, we recommend the 232USB9M adapter (not required).
  • VR1980 is recommended for ObserVR1000 calibration verification; an alternative option is provided.
  • Equipment is available for purchase through Vibration Research.

Option 3: Perform Calibration Yourself

Create and run your own custom calibration procedure and documentation. Any factory support provided for your custom procedure will be billed at an hourly support rate.

Equipment Required

  • Agilent DMM 34401A, 34410A, 34461A, 34465A, 34470A & 3458A (see chart below for compatibility)
  • 5 BNC cables and 4 BNC Tees
  • Differential adapter cable
Meter Model 34401A 34410A 34461A 34465A 34470A 3458A
Viable Version All Versions All Versions 2015.3+ 2019.1+ 2015.3+ 2015.3+

Connecting the DMM

  • Requires a version of the Agilent IO Library. Specifically, you will need the Connection Expert software to use the 34410 or newer through USB direct or Ethernet.
  • You must use a null modem cable for serial communication with the 34401A.
  • We recommend the B+B Smartworx 232USB9M for a serial to USB converter. Drivers are included in a CD that comes with the hardware. We have seen issues with other brands and recommend only using the B+B Smartworx. Otherwise, converters can be found here.
