TSR Sensor Offset (Zeroing) Procedure

The TSR (PRO, PRO-HB, and DXP) sensor offset is adjusted within TSR Control version 1.02.xxxx and greater. If you are a registered user, software is here:

https://support.dtsweb.com/hc/en-us/sections/200320203-TSR-Control

TSR offset can be performed at any time and is recommended before any series of testing is performed . The offset is best performed when the real-time view (after 20 seconds of stabilization) exceeds ~0.25% of the sensors full scale as follows:

• >0.12g for 50g range
• >0.50g for 250g range
• >1.25g for 500g range
• >15.0g for 6000g range

General Notes 

• The TSR PRO and PRO-HB accelerometers are sensitive to orientation (DC response), ensure the TSR is offset in the planned installation orientation
• The TSR DXP models use a piezo-electric accelerometer. Allow the TSR DXP accelerometers to stabilize for at least 20 seconds before verifying the offset in real-time
• All sensors exhibit offset differences with changes in temperature
• Offset is expected to be <0.1% of sensor full scale after performing the procedure below

To adjust the sensor offset

1. Start TSR Control 2
2. With the TSR connected and recognized, select SETTINGS
3. When the SETTINGS menu opens, select Offset and GO
1. Note: If the Offset menu is not available then set the following value in the "TSRControl2.XML" file by opening in Notepad and ensure the software is closed before editing the XML
2. <AllowOffsetCorrection>true</AllowOffsetCorrection>
4. 
5. The software will power the sensors and allow them to stabilize. After several seconds
6. The OFFSET and REMAINING fields will be populated
7. The remaining offset is expected to be less than 0.1% of the sensors full scale
