2 DATA LOGGER SETUP
Data Logger is set up with the help of LoggerSoft PC software. Follow
User's Manual, Data Logger Setup, Data Logger Settings. Starting Data Logger
can be done either during setup or by pressing the buttons. Below are the features
of the Data Logger setup, not marked in Logger soft, User's Manual.
2.1Logging Interval
Valid Logging Interval limits are from 1 to 60 minutes.
The list of valid values: 1 min; 2 min; 3 min; 5 min; 10 min; 15 min; 20 min;
30 min; 60 min.
It’s important: After changing the archiving period, the previous data is
overwritten.
2.2Logging Modes
TILL THE MEMORY FULL. Logging starts from the launch moment and
stops after filling all the memory (from the start point). Restart logging is
only possible after re-configuration.
CYCLIC. Logging is continuous, cyclically wiping the oldest data with
new data.
2.3Options for starting Logging
AFTER SETTING. Logging starts immediately after Data Logger setup
without user intervention.
BY BUTTON. Logging starts after pressing the button.
AT SPECIFIC TIME.
For options After Setting and By Button, the Delayed Start option is available
(see paragraph 2.4).
NOTE:Before selecting option for starting logging it is necessary to
synchronize time (Logger soft, User's Manual, Data Logger Setup, Time
Synchronization).
Important: Performing the time synchronization stops the current logging.

2.4Delayed Start
There are two types of Delayed Start.
LOGGING DELAY. This is the delay since the logging start (see
paragraph 2.3 Options for starting Logging) until the actual start of
logging.
ALARM STATISTICS DELAY. This is the delay after the alarm is turned
on by button before the actual start of the alarm statistics collection.
2.5Alarm Processing
If the data is logged, the Data Logger operates in one of two states:
ALARM ON. In this state, Data Logger measures the sensor readings,
archives them and keeps alarm statistics according to the settings.
ALARM OFF. In this state, Data Logger measures the sensor readings,
archives them but does not keep alarm statistics.
The initial state of the logger after logging start is set in Data Logger Setup.
In the future, the alarm is ON / OFF by clicking on the button. Multiple ON / OFF
during data collection (for multiple uses) is possible.
2.6Alarm Conditions
Data Logger has three types of alarm conditions:
DISABLED
HIGH/ LOW
MULTILEVEL(Only for internal temperature channel).
ATTENTION! The alarm can only be reset using the reconfiguration.
2.7High/Low Limits Alarm Settings
Under this condition, the High and Low limits, alarm delay and method of
recording trigger delay (for each violation or total for all violations) are set. If the
sensor readings are within the specified limits or if they briefly go beyond the limits
of values, the alarm does not turn on. If any of the limits is violated for a time longer
than the delay, alarm is triggered.
2.8Multilevel Value Scale
Five limits divide the scale of values into six zones. The zones are numbered
from top to bottom from 1 to 6. Zone 4 is a zone of acceptable values. For other
zones, the following is indicated:
alarm delay;
method of recording trigger delay (for each violation or total for all
violations);
allowable number of limit violations.
In addition, there is an option "3 + 5" - the combination of zones 3 and 5. This
is the extension of permissible values to zones 3, 4 and 5.
Zones 1, 2 and 6 can be disabled.

2.9Restrictions of Control Buttons
BUTTONS INACTIVE. Available only Flash Drive / COM Port mode
switching and indication call.
START ONLY. Everything is allowed, as in the paragraph 1, plus the start
of logging.
ONLY ONE USE.Everything is allowed, as in the paragraph 2, as well as
alarm ON/OFF. But you can activate the alarm only once.
MULTIPLE USE. Everything is allowed, as in the paragraph 3, but the
alarm can be turned ON and OFF many times.
3 BATTERY LIFE
3.1 The lifetime of Data Logger is determined by the lifetime of the battery
EF702338. The main influencing factors that reduce the lifetime of the element:
self discharge of the element during storage or operation at elevated
temperature;
activated indication on the logger screen;
short logging interval.
3.2 Table 4 shows the predicted operating time of Data Logger at different
temperatures, with different logging intervals without activated indication and with a
fresh battery.
