Stores over 16,000 readings
EasyLog 21CFR software available as a free download
Logging rates between 10 seconds and 12 hours
High contrast LCD, with two and a half digit temperature display function
Immediate, delayed and push-to-start logging
User-programmable alarm thresholds
Use as part of a 21CFR Part 11 compliant system
This standalone data logger measures and stores more than 16,000 temperature readings over a -35 to +80°C (-31 to +176°F) range
with a resolution of 0.5°C (1°F).
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 high contrast LCD can show a variety of temperature information. At the touch of a button, the user can cycle between the
current, maximum and minimum stored values for temperature.
The data logger is supplied with a lithium metal battery which gives three years’ logging life. The logger is protected against ingress
from water and dust to IP67 standard when the cap is fitted.

DISPLAY STATUS INDICATION
Maximum logged
value symbol
The EL-21CFR-1-LCD features a high contrast LCD which shows
logged temperature values using seven segment numbers, along
with annunciators. The LCD can also show information regarding
the logging status.
Negative symbol
The LCD shows three different recorded readings, which can be
cycled through using the built-in push button. The most recent
logged temperature, maximum logged temperature and minimum
logged temperature can be displayed.

Logger Status
Explanation
Delayed Start
This is shown when the logger is set to start at a specific date and time. If the logger is set to ‘LCD off’ or ‘LCD
on for 30 seconds’ mode, then this will only be shown after the button is pressed. Otherwise the display will
remain blank
Push to Start
This is shown when the logger is set up for ‘Push to Start’ logging
Logging
This is shown when the logger is running in ‘LCD off’ mode, and the button is pressed. The display clears
again after three seconds
Stopped
If the logger has not been set to log and the button is pressed, three dashes are displayed for a few seconds

LED STATUS INDICATION
The EL-21CFR-1-LCD features two LEDs:
▪ The first LED flashes red to indicate that the EL-21CFR-1-LCD 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-1-LCD is not in an alarm condition.
Using EasyLog 21CFR 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 not currently logging, but is primed to start at a later date and time (delayed start)
Green single flash (every 20 seconds)
The data logger is currently logging. No alarm
Green single flash (every 30 seconds)
The data logger is full and has stopped logging. No alarm
Green double flash (every 20 seconds)
The data logger is currently logging. Low alarm
Red single flash (every 10 seconds)
The data logger is full and has stopped logging. Low alarm
Red single flash (every 20 seconds)
The data logger is currently logging. High alarm
Red double flash (every 10 seconds)
The data logger is full and has stopped logging. High alarm
Red double flash (every 20 seconds)
The battery is running low. Data logging will continue until the battery voltage drops below 2.8V
Red/Green single flash (every 20 seconds)
The battery is running low. Data logging will continue until the battery voltage drops below 2.8V
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.
