*PWC - Set Personal Wavelength Correction in nm
This command is used to specify the wavelength in nm being used on the HP-BLU. The internal memory
contains measured spectral data for a wide range of wavelengths. A valid value is set between the lowest
and highest wavelengths supported by the device, and it should not be a floating-point value. The input
parameter must have 5 digits. If the desired wavelength does not have 5 digits you must enter a zero-
padded number. For example, to set the wavelength at 514 nm, you must enter 00514.
Specifying zero as a wavelength or providing an out-of-bound value as a parameter has no effect.

Parameters
Answer
PWC
Wavelength nm (5 digits)
Active
wavelength
and
correction factor
Default:
Calibration wavelength, (typically 1064 nm, varies with the HP-BLU model)
Example
The following example sets the wavelength to 1550 nm.
Command: *PWC01550
Answer: Wavelength = 1550.000000 nm,
factor = 1.000000<CR><LF>
*PWM - Set Personal Wavelength Correction in microns
This command is used to specify the wavelength in microns. The internal memory contains measured
spectral data for a wide range of wavelengths. A valid value is set between the lowest and highest
wavelengths supported by the device. The input parameter must have 5 digits and can be a floating-point
value. If the desired wavelength does not have 5 digits you must enter a zero-padded number. For example,
to set the wavelength at 10.6 micron, you must enter 010.6. Please note that the resolution is limited as
follow:
Wavelength Range
Resolution limit
Less than 100 µm
10 nm
Greater than 99.99 µm or less than 1000 µm
100 nm
Greater than 999.9um
1 µm
Specifying zero as a wavelength or providing an out-of-bound value as a parameter has no effect.
