Probes the Z-height using a specified channel on a liquid handling device. Commands the liquid handler to perform a Liquid Level Detection (LLD) operation using the specified channel (this means only conductive materials can be probed!).

Parameters:

  • self – The liquid handler.

  • channel_idx (int) – The index of the channel to use for probing.

  • lowest_immers_pos (int) – The lowest immersion position in increments.

  • start_pos_lld_search (int) – The start position for LLD search in increments.

  • channel_speed (int) – The speed of channel movement.

  • channel_acceleration (int) – The acceleration of the channel.

  • detection_edge (int) – The edge steepness at capacitive LLD detection.

  • detection_drop (int) – The offset after capacitive LLD edge detection.

  • post_detection_trajectory (Literal[0, 1]) – Movement of the channel up (1) or down (0) after contacting the surface.

  • post_detection_dist (int) – Distance to move up after detection to avoid pressure build-up.

  • move_channels_to_save_pos_after (bool) – Flag to move channels to a safe position after operation.

Returns:

float – The detected Z-height in mm.

Return type:

float
