Issue 3 10/2018 Page 1 of 4
This standalone data logger measures and stores more than 32,000 temperature readings from a J, K or T-type thermocouple at
a resolution of 0.5°C (1°F). It comes supplied with a K-type thermocouple capable of measuring from 0 to +200°C (32 to +392°F).
Your application will determine which probe is most suitable based on temperature range, accuracy, form and price. A wide variety
of alternative thermocouples are available. Please call Lascar for vendor recommendations.
The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free
EasyLog 21CFR software. Data can then be graphed, printed and exported to other applications for detailed analysis. The encrypted
data has full audit tracking to comply with the requirements of 21CFR Part 11.
The data logger is supplied with a lithium metal battery which typically gives 2 years’ logging life.

STORE DATA IN COMPLIANCE WITH THE REGULATIONS OF 21CFR PART 11
Easy to install and use, Lascar’s EasyLog 21CFR software is compatible with all latest versions of Windows (7, 8 & 10 - both 32-bit &
64-bit) and is available as a free download from www.lascarelectronics.com/software/easylog-21cfr. All data collected from the
logger and associated audit trails are stored in an encrypted format which cannot be edited.
CONTROL YOUR LOGGER
Users can configure their loggers with the following parameters:
• Logger name
• Temperature measurement parameter (°C or °F)
• Logging rate (user selectable between 1 second and 12 hours)
• High and low alarms for temperature
• Immediate and delayed logging mode
Once users have recorded data, the built-in graphing software allows
them to graph and annotate their data, or export it to Excel, PDF
or jpeg formats.
CONTROL YOUR DATA
EasyLog 21CFR software ensures digital security and compliance:
• Assign individual users with specific permissions
• Full software & session data audit trails
• Receive email alerts for failed log in attempts
• Digital signatures added to all reports
• Add comments to specific readings

LED STATUS INDICATION
EL-21CFR-TC features two LEDs:
▪ The first LED flashes red to indicate that the EL-21CFR-TC is in an alarm condition. It will flash when the logged temperature
has exceeded a Low or High alarm level.
▪ The second LED flashes green to indicate that the EL-21CFR-TC is not in an alarm condition.
Using EasyLog 21CFR Software it is possible to set the alarm to remain active even if the reading has returned to normal, in which
case the alarm LED will continue to flash red. This ‘Hold’ feature in the software ensures the user is notified that at some point an
alarm level has been exceeded, without needing to download the data.
Hold is enabled by default, and can be turned off via the control software. The red LED will then only flash whilst the logger is in an
alarm condition. When the temperature returns to normal, the green LED will flash.
Green single flash (every 10 seconds)
The data logger is currently logging. No alarm
Green single flash (every 20 seconds)
The data logger is currently logging, however the battery is running low. No alarm
Green single flash (every 30 seconds)
The data logger is not currently logging, but is primed to start at a later date and time (delayed start)
Green double flash (every 20 seconds)
The data logger is full and has stopped logging. No alarm
Red single flash (every 10 seconds)
The data logger is currently logging. Low alarm
Red single flash (every 20 seconds)
The data logger is currently logging, however the battery is running low. Low alarm
Red double flash (every 10 seconds)
The data logger is currently logging High alarm
Red double flash (every 20 seconds)
The data logger is currently logging, however the battery is running low. High alarm
Red & Green single flash alternately (every 20 seconds)
The data logger is full and has stopped logging. High or low alarm
No LEDs flash
The data logger is stopped, the battery is empty or there is no battery

BATTERY INFORMATION
Replacement
We recommend that you replace the battery annually, or prior to logging critical data. Only use 3.6V ½AA lithium metal batteries.
The data logger does not lose its stored readings when the battery is discharged or replaced; however, the data logging process will
stop and will not resume until the battery is replaced and the logger restarted by the EasyLog 21CFR Software.
Before replacing the battery, remove the data logger from the PC. Please note that leaving the data logger plugged into the USB
port for extended periods will cause some of the battery capacity to be lost.
Passivation
If left unused for extended periods of time lithium metal batteries, including those used in the EasyLog range of data loggers,
naturally form a non-conductive internal layer preventing them from self-discharge and effectively increasing their shelf life. When
first installed in the data logger, this may cause a momentary drop in the battery voltage (the Transient Minimum Voltage) as
the internal layer is broken down, resulting in the data logger resetting. Inserting the batteries in the data logger and leaving it
connected to a PC for about 30 seconds will remove this layer. After this, remove and re-install the batteries to reset the data
logger. Overall battery life will not be affected.
WARNING
Handle lithium metal batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.
