Calibration

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
The instrument is factory calibrated and the laser light source is stable. The manufacturer
recommends that a calibration verification be done periodically to make sure that the system
operates as intended. The manufacturer recommends calibration after repairs or comprehensive
maintenance work.

Configure the calibration settings

Select the calibration curve, calibration interval and more.
1. Push Calibration.
2. Push Options>Calibration Setup.
3. Select an option.
Option Description
Calibration Selects the type of standard and the calibration curve (range). StablCal RapidCal
Curve (0–40 FNU) (default)—1-point calibration (20 FNU) with StablCal. StablCal (0–1000 FNU)
—2-point calibration (20 FNU and 600 FNU) with StablCal. Formazin RapidCal
(0–40 FNU)—2-point calibration (20 FNU and dilution water) with Formazin. Formazin
(0–1000 FNU)—3-point calibration (20 FNU, 600 FNU and dilution water) with Formazin.
Degrees (0–100 mg/L)—3-point calibration (20 mg/L, 100 mg/L and dilution water) with
kaolin. SDVB (0–1000 FNU)—3-point calibration (20 FNU, 600 FNU and dilution water)
with spherical slyrene divinylbenzene. Custom Calibration—1- to 6-point calibration
(0.02 to 1000 FNU) with StablCal or Formazin. The user selects the number of calibration
points and the value of each calibration point.
Verify after Cal. Sets the instrument to start a verification immediately after the instrument is calibrated.
When set to on, the verification standard is measured immediately after a calibration is
done. Default: ON.
Calibration Sets the time interval between calibrations. When a calibration is due, the display will
Reminder show a reminder and a question mark on the calibration icon at the top of the display.
Options: Off (default), 1 day, 7 days, 30 days or 90 days. When a calibration is done, the
calibration time is set to zero.
Reset to Sets the calibration settings to the factory defaults.

Calibrate the instrument

The instrument is factory calibrated.
1. Log in to the instrument as follows:
• Put an operator RFID tag in front of the RFID module or
• Push Login. Select the applicable operator ID, then push Select.
2. For RFID vials, put the vial in front of the RFID module. Refer to
A calibration is started. The instrument receives the value, the lot number, the expiration date and
the Certificate of Analysis information from the RFID vial.
3. For non-RFID vials, push Calibration.
