3.2 Calibrate with StablCal vials with RFID
Items to collect:
• TU5300 or TU5400 instrument with RFID functionality
• RFID calibration vials:
• 20 NTU StablCal vial with RFID
• 600 NTU StablCal vial with RFID
Or
• StablCal calibration set with RFID (LZY835) which includes 10 NTU, 20 NTU, and 600 NTU
There are four procedures to calibrate the instrument with StablCal vials with RFID based on the
selected calibration settings:
• Set the CAL CURVE setting to STABLE CAL 0-40 NTU and the VER AFTER CAL setting to OFF
for a 1-point calibration without verification. Refer to
on page 7.
• Set the CAL CURVE setting to STABLE CAL 0-40 NTU and the VER AFTER CAL setting to ON
for a 1-point calibration with verification. Refer to
• Set the CAL CURVE setting to STABLE CAL 0-700 NTU and the VER AFTER CAL setting to OFF
for a 2-point calibration without verification. Refer to
on page 11.
• Set the CAL CURVE setting to STABLE CAL 0-700 NTU and the VER AFTER CAL setting to ON
for a 2-point calibration with verification. Refer to
If calibration with verification is used, make sure to measure the verification standard with the menu
item Define Std Val. Refer to
Note: Although the MENU GUIDED calibration setting is enabled, the controller display will not show guidance
during the RFID calibration. The LED and the button on the instrument are the guidance during the RFID
calibration. Refer to the applicable calibration procedure.
