Introduction
The 9105D field verification system allows users of Metrix’s models HI-903 and HI-913 portable vibration
calibrators (PVC) to duplicate the original factory calibration of the portable calibrators, thereby re- certifying
the device’s accuracy without returning it to Metrix. The 9105D system includes the following:
Model 353B04 quartz accelerometer from PCB Piezotronics
Model 482A21 ICP® signal conditioner from PCB Piezotronics
Model 003C05 10-32 to BNC male 5 ft. cable from PCB Piezotronics
BNC male to BNC male cable (Quantity 2)
BNC T-connector
BNC jack to banana plug connector for digital volt meter
10-32 male to ¼-28 male BeCu mounting stud
Silicone Grease & Syringe
USB memory stick pre-loaded with:
o
Microsoft Excel® PVC Field Validation Workbook (MD-0289)
o
System calibration certificate showing reference sensitivity and deviations at various frequencies
for models 353B04 accelerometer and 482A21 signal conditioner tested as a system by Metrix. A
printed copy of this calibration certificate is also included.
Users will need to provide the following equipment to perform the test:
Torque wrench
Calibrated volt meter
Model HI-903 or HI-913 portable vibration calibrator
Metrix understands it is not always possible for users to return their equipment to our ISO 17025 accredited
calibration lab in the United States for re-certification. The 9105D allows users to re-certify their equipment
without returning it to our lab. Most countries and regions do not have access to a calibration lab that
includes portable vibration shakers/calibrators on its “scope of accreditation”. However labs accredited for
accelerometer calibration are much more prevalent. Hence, the accelerometer and signal conditioner
included with 9105D can be sent to these accredited labs for re-calibration at the user’s discretion. These
calibrated devices can then be used to verify output of the portable vibration calibrator.
