LogTag Recorders LogTag Analyzer Temperature Recorder ユーザーズマニュアル

Enable pre-start logging  Pre-start logging is a feature that protects the recording in the 

event of a failure to actually press the START MARK button to 

initiate the recording. It is an insurance policy against the loss of 
critical data. This is almost always checked for transit monitoring 

applications. This option is further explained in the section "

". 

Record readings 

continuously, overwrite 

oldest when memory 

full 

This is what is called a “data wrap” in which the recorder just keeps 

writing data to memory. It is a “moving window” of data. For 

example, this is useful for fixed base MKT monitoring with the 

interval set to one year, so that the current “yearly MKT” can 

always be in the memory of the LogTag. If this option is selected, 

the user will be “opted out” of the next two options. This option is 
further explained in the section "

". 

Record readings so 

that: 

If this is selected, the logger stops logging when the number of 

data points has been gathered and stored in memory that spans at 
least the number of days specified below. When this option is 

selected, the following two options will determine the number of 

data points over the span of time that will be recorded. 

Readings recorded will 

span at least X days 

If you know how long you want to record, the Configuration screen 

will automatically set the number of readings to be collected at a 

particular interval. This setting will only have an effect if the above 

option "Record readings so that:" is selected. 

Number of readings to 

record X maximum is Y 

This data box will display the calculated number of readings if you 

select a time span and an interval. Alternatively, you can select the 

number of readings desired, and the time span will be altered 

based on the interval. If this is selected, the logger will stop logging 

when the number of readings has been gathered and stored in 
memory. "Y" represents the maximum number of readings the 

LogTag can store, however with a selected interval and a selected 

time span, you may not need to use all of the available data space. 

This setting will only have an effect if the above option "Record 

readings so that:" is selected. 

Record a reading every 

X  

This determines how frequently the LogTag records the 

environmental humidity and/or temperature into its internal 

memory. 

Begin recording after a 

delay of X 

Determines how long after the START MARK button on the LogTag 

has been pressed that it will actually begin to record the 

environment humidity and/or temperature. This feature is useful for 
example, when the LogTag could falsely trigger an alert because 

the environmental conditions it is being started in is quite different 

to the environmental conditions to be monitored. If pre-start 

logging is enabled, the LogTag will continue to record pre-start 

readings during this delay. 

Enable the OK (Green) 

indicator 

This determines whether or not the green light should function 

while the LogTag is recording after being started. 

Humidity / Temperature  These tab controls will allow the humidity and temperature alert 

conditions to be configured independently. These tab controls will 

only appear when configuring a LogTag that has a humidity and a 

temperature sensor. If the LogTag has only one sensor then the 

following alert conditions will apply to that sensor.
