Using a Digital Data Logger

1. Using a Digital Data Logger North Carolina Immunization Program (NCIP)

2. WHY A DIGITAL DATA LOGGER? • Provides accurate temperature history • Reflects actual vaccine temperatures • Provides an indication of length of time a unit has been operating outside recommended storage temperature • Less expensive than replacing vaccines wasted due to inaccurate temperature readings - There are a variety of devices available

3. CDC RECOMMENDATIONS(REQUIRED OF ALL NEW PURCHASES AND FOR ALL PROVIDERS AS OF JANUARY 1, 2018) • Digital display on outside of storage unit • Detachable probe in a bottle filled with a thermal buffer, like glycol • Continuous monitoring and recording capabilities • Display of current, as well as minimum and maximum temperatures.

4. BEFORE YOU GET STARTED • Models are available in a single or double probe arrangement • -How many units do you have and how close together are they? • All models require a dedicated outlet without a ground-fault-interrupter and without the use of a surge protector • With double units, determine which unit is “Probe 1” and which unit is “Probe 2”

5. ITEMS SUPPLIED • Traceable Excursion-Trac™ Thermometer (“Data Logger”) • A/C Adapter (primary source of power)

6. ITEMS SUPPLIED • AAA Batteries installed, pull tab to activate batteries NOT YET! • Glycol bottle with probe cable P1 (single bottle) • Two bottle probe includes P1 and P2 cable/bottle

7. ITEMS SUPPLIED • Instructions • Certificate of Calibration DO NOT LOSE! DO NOT LOSE! DO NOT LOSE! • Static Suppressor for probes • Velcro and Magnets DO NOT USE WITH PROBE

8. STEP #1: PLACE THE PROBE

9. STEP #2: POWER SUPPLY • Thermometer must be powered at all times with supplied AC adapter • Insert AC adapter plug into the unit, and plug the AC adapter directly into a wall socket (do not plug into a surge protector) • Backup AAA batteries will power thermometer for one week in the event of a power failure • - Pull tab to activate batteries on back of unit

10. STEP #3: STATIC SUPPRESSOR The static suppressor is installed to eliminate interference due to radio frequency. Static within the cable can cause the unit to malfunction.

11. STEP #4: SET ALARM LIMITS

12. SETTING REFRIGERATOR ALARM LIMITS • Refrigerator settings in Celsius • Low alarm 2°C • High alarm 8°C • Refrigerator settings in Fahrenheit • Low alarm 35°F • High alarm 46°F Current room temperature while setting alarm

13. SETTING FREEZER ALARM LIMITS • Freezer settings in Fahrenheit • Low alarm -58°F • High alarm 5°F • Freezer settings in Celsius • Low alarm -50°C • High alarm -15°C Current room temperature while setting alarm

14. STEP #5: SET THE DATE & TIME • Setting the year, day, month and time is an important step to ensure the Excursion-Trac™ properly records the actual time and date of temperature readings • Slide the DISPLAY switch to the DATE/TIME position • Press the SELECT button to enter the setting mode • Press the ADVANCE button to increase the selected date or time

15. STEP #6: SET THE LOGGING INTERVAL • Set the unit to record at intervals of 30 minutes • To increase the logging interval to read at 30 minute intervals, press the ADVANCE button until 0:30 is displayed • Slide the MEM VIEW switch to the OFF position to complete/close the setting • Use the CLEAR button to erase the memory of the data logger the first time it is put in use.

16. STEP #7: ENABLE ALARMS • ENABLING/DISABLING ALARMS • Wait for probe to cool down to an in-range temperature • Slide the ALARM switch to the ON or OFF position to enable or disable the alarms • Do not disable alarms

17. STEP #8: PLACE THE DATA LOGGER • Guide wires to ensure that staff do not accidentally pull the probe out of place or unplug the wires • Packing tape may be used to hold wires in place

18. REGULAR USE OF YOUR DATA LOGGER

19. VIEWING MINIMUM/MAXIMUM MEMORY • The minimum or maximum temperature stored since the last clear of min/max memory • Slide PROBE SWITCH to the desired P1 or P2 • Slide the DISPLAY switch to the MIN/MAX position • Thermometer will display the current, minimum, and maximum temperatures for the probe

20. RECORDING TEMPERATURE • PROVIDERS MUST MANUALLY RECORD ALL OF THE DATA BELOW EVERY DAY THAT YOUR CLINIC IS OPEN! • Opening (or morning) temperature with date, time, and recorder’s initials • Minimum and maximum temperatures (morning only). Press the CLEAR button once recording min/max temperatures • Closing (or afternoon) temperatures with date, time, and recorder’s initials • PLEASE VISIT IMMUNIZE.NC.GOV TO PRINT NEW LOGS

21. DOWNLOADING STORED DATA • Insert a formatted USB flash drive into the logger • P1 and P2 light will come on • Leave the USB flash drive in the logger until the light goes off • File automatically creates a .csv file on the USB drive • Once the light is off, remove the USB flash drive

22. REVIEWING STORED DATA • Plug your USB drive into a computer • Open the CSV file created by the data logger • Review all temperatures to ensure that all readings are in-range • Data review should be completed by a different staff member than the staff who manually records temperatures • Save file for 3 years

23. WHAT IF I FIND AN OUT-OF-RANGE TEMPERATURE? • Thermometer buzzer will sound when an out-of-range temperature occurs • LED for the alarming temperature channel will flash (P1 or P2) • Active alarm may be cleared by pressing the CLEAR SILENCE ALM button or disabling the alarm by sliding the ALARM switch to OFF position • CALL THE NCIP STORAGE AND HANDLING PHONE LINE IMMEDIATELY UPON DISCOVERY OF AN OUT-OF-RANGE TEMPERATURE REGARDLESS OF HOW FAR OUT OF RANGE OR HOW LONG IT WAS OUT OF RANGE! • 919-707-5574
