21.5 Image Sensor Reticle
The internal image sensor is used for automatic sighting. The offset value is set to correct the position of the
image sensor in relation to the telescope reticle, but if for whatever reason the telescope reticle and image
sensor become misaligned, automatic sighting of the center of the prism cannot be performed correctly and
this will adversely affect angle measurement. Check and adjust it as outlined below.
• Perform check and adjustment in weak sunlight and no scintillation.
• It may take up to 20 seconds for an offset value based on the measurement results to appear.
• Use Standard prism AP01AR or Compact prism CP01. Using other prism types may result in adjustment
inaccuracies.
• It is recommended to adjust image sensor reticle before the measurement especially when accurate result is
desired in single face observations by Auto Pointing/Auto Tracking.
