3.1.3 Calibration
(1) When performing a calibration using 0.2 or 1.0 µm filtered water as zero reference, refer to
section 3.1.4.
(2) When performing a 2-point calibration using standard solutions, refer to section 3.1.5. Use this
method to perform a calibration complying with EPA 180.1.
Note: The instrument has been pre-calibrated using 0.2 µm filtered water as zero reference at the
factory before shipment.
