Open the optical housing to check filters for crazing, moisture ingress, or physical scratches.
The instrument automatically samples air channels for each installed wavelength filter, adjusting the potentiometers (or digital DAC values) to achieve the target reference voltage (typically 4.0 to 4.5 Volts DC). 5. Troubleshooting Error Codes
Tighten the bracket screws securely, ensuring the filament remains perfectly centered relative to the aperture. Calibration Verification
Explanation of filters and photo detector mechanism.
