Help my Agera is not recognizing my port plate, invalid port plate.

New port plate sensor design is used in Agera AGR00477 and above. The sensor board and the port plate is updated correspondingly to this. Old design has the optical sensor, and the new design has the magnet sensor. If you have the new sensors (serial number >=00477), please keep using the updated port plate. If  you have the older sensors (serial number <00477) and need to use the new port plate, please check with support@hunterlab.com to update the sensor board.  

Here are the part numbers of port plates used with old and new port plate design: 

If a correct version of port plate is used while Agera Essentials still could not recognize the port plate, please go to Workspace menu/Diagnostics/Advanced Diagnostics, put the port plate on the Agera, then  click "Port Plate" in advanced diagnostics, it will show the detected signal in data view at the right side of  this dialog.

Here is the general list of port plates: 

For all the standard 2''/1''/0.625'' port plates, the gloss detection is enabled.

LAV​ standard port plate : index 0001 Green-Red-Red
MAV standard port plate: index 0004 Red-Red-Green
SAV standard port plate: index 0002 Red-Green-Red

The port plate with gloss disabled (PP index 0003, 0005, 0006) can be detected correctly when Agera has

Essentials Rev1.01.0062 and above

and Firmware V1.10.19.239A and above.

Essentials and firmware version can be checked at Agera Essentials/About/Info.

If Agera has Essentials version lower than Rev1.01,0062, please download the latest Agera Essentials and upgrade. 

If you need to use these special port plates (PP index 0003, 0005, 0006) while the Agera has the older firmware version, please contact us support@hunterlab.com. In this case, the instrument needs to ship back to Service for firmware upgrade. 

For optical sensor in old port plate sensor design: 

When a wrong port plate index is detected in Agera Essentials/Diagnostics/Advanced diagnsotics, please check the back side of the port plate to make sure that all the three dots are placed correctly and no scratches on them. Following is an picture of 2'' standard port plate, there are three dots, #1 white, #2 black, and #3 black.

If any of the white/black dots has become scratched or dirty it could cause a wrong port plate index detected. We are working on a new system using magnets instead of stickers to avoid damaged dots. 
If these dots are placed correctly and not damaged while a wrong port plate index is still reported, it might be caused by bad dot detectors in Agera.
