operates as intended. The manufacturer recommends calibration as local regulations require and
after repairs or comprehensive maintenance work.
3.1 Configure the calibration settings
Select the calibration curve, calibration interval, output behavior during calibration and more.
1. Push menu.
2. Select SENSOR SETUP>TU5x00 sc>CALIBRATION>SETUP.
3. Select an option.
Option Description
MENU GUIDED Sets menu-guided calibration to SEALED VIAL, SYRINGE or OFF (default). Calibration
instructions show on the controller display
SYRINGE.
Note: The MENU GUIDED option does not show when sealed vials with RFID are used.

CAL CURVE Selects the type of standard and the calibration curve (range).
STABLCAL 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 0–40 FNU—2-point calibration (20 FNU and dilution water) with Formazin.
FORMAZIN 0–1000 FNU—3-point calibration (20 FNU and 600 FNU and dilution water)
with Formazin.
CUSTOM—2- 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.
STABLCAL 0–40 NTU (or 0–40 FNU) (default)—1-point calibration (20 NTU or 20 FNU)
with StablCal.
STABLCAL 0–700 NTU (or 0–1000 FNU)—2-point calibration (20 NTU and 600 NTU or
20 FNU and 600 FNU) with StablCal.
FORMAZIN 0–40 NTU (or 0–40 FNU)—2-point calibration (20 NTU and dilution water or
20 FNU and dilution water) with Formazin.
FORMAZIN 0–700 NTU (or 0–1000 FNU)—3-point calibration (20 NTU and 600 NTU and
dilution water or 20 FNU and 600 FNU and dilution water) with Formazin.
CUSTOM—2- to 6-point calibration (0.02 to 700 NTU or 0.02 to 1000 FNU) with StablCal
or Formazin. The user selects the number of calibration points and the value of each
calibration point.
VER AFTER Sets the instrument to start a verification immediately after the instrument is calibrated.
CAL When set to on, the verification standard is measured immediately after a calibration is
done. Default: ON. Refer to
CAL Sets the time interval between calibrations. The controller will show a reminder when a
REMINDER calibration is due. When a calibration is done, the calibration time is set to zero. Options:
OFF(default), 1 day, 7 days, 30 days or 90 days.
OUTPUT MODE Selects the output behavior during calibration. ACTIVE—The outputs continues to give the
measurement values during calibration. HOLD (default)—Keeps the outputs at the last
measurement value before calibration. The outputs give the measurement values again
when the calibration procedure is complete. SET TRANSFER—Sets the outputs to the
SET TRANSFER value selected in the controller settings. Refer to the controller setting for
more information.
CAL POINTS When the CAL CURVE setting is set to CUSTOM, this option sets the number of
calibration points (2 to 6). This option only shows when the CAL CURVE setting is set to
CUSTOM.
