Description:

Used in conjunction with the "hpoffset" parameter to convert the raw results of "head power full" and "head power off" measurements into Watts out of the head.

The raw reading of the shutter sensor is affected by the "head hpwrgain" parameter setting so changing this value will require commensurate changes to "hpslope".

This value can only be calibrated if an external power meter is available and hence this parameter should not be changed from its factory setting.

Type:

Default:

• 300.000

Range:

• 100.000 to 400.000

Notes:

Note that the "head power sum" command is the more reliable way to measure power out of the head with firmware versions greater than 1.5.
