Myron L ULTRAPENX2 PTBT6 Calibration Instructions

ULTRAPEN
Instructions for Performing a Basic, 1-Point
Myron L ® Company recommends calibrating the PTBT6 before each series of tests, depending on usage.
I GENERAL NOTES
•
IMPORTANT: The Nitrate sensor should be conditioned prior to performing a calibration (see SENSOR CONDITIONING
section of the PTBT6 Quick Start Instruction sheet).
• Calibration solutions must be prepared prior to use.
• This calibration procedure describes a 1-point Calibration using the 100 ppm, NO
included in the shipping box of your instrument.
o For greatest accuracy complete a 2-point calibration as described in the PTBT6 Operation Manual. Download

• ALWAYS keep the temperature of the prepared calibration solution(s) the same as the test solution.

USING THE PIPETTE TO DRAW SOLUTION:

1. Depress the pipette plunger to the 1st stop.
2. Place tip in ISA solution and release slowly.
3. To dispense, depress pipette plunger completely to the 2nd stop.
• DO NOT contaminate the pipette tip by touching it with your fingers or setting it on a dirty worksurface.
• DO NOT dip the pipette tip in the calibration solution as this will cause cross-contamination between solutions.
II. PREPARING CALIBRATION SOLUTION
NOTE: reference solution(s) must be prepared prior to calibration. For each standard solution selected:
1. Fill a graduated cylinder to the 10 mL line with the reference solution.
2. Add 200 µL of the Nitrate ISA solution to the graduated cylinder (using the supplied 100 µL pipette).
3. Replace the cap on the graduated cylinder and shake well to mix the prepared reference solution.
III. 1-POINT CALIBRATION
You will need prepared 100ppm reference solution, clean water (preferably DI, RO, or distilled), and a clean, dry, lint-free cloth.
1. Remove the protective / hydration cap from the Nitrate sensor.
2. Rinse sensor for about 5 seconds with clean water (preferably DI, RO, or distilled).
3. CAREFULLY blot the sensor membrane with a soft, clean, lint-free cloth or tissue to remove any water drops.
4. Dip the pen in the prepared 100 ppm reference solution. Make sure the sensor is completely submerged.
5. Swirl it around to remove any bubbles that may have been caught in the sensor.
6. Tap the CAL button
7. The Initial CAL screen will appear.
8. Tap the CAL button.
