Analyzer
The analyzer can analyze the file recorded and provides the analysis results of the
channel voltage, current and power, such as the average, VAR and range.
Press
 Analyzer to open the analyzer setting interface. You can open the
record file stored, set the analysis parameters, execute analysis and view the
analysis results.
You can analyze the stored record file and view the analysis results following the
steps below.
1. Open the record file
Press Open File to enter the store and recall interface. The file type is fixed at
“*.rof”. Select the desired record file and press Read.
At this point, the current time and start time are both the record period of the
file opened. When the number of groups of the file opened is less than or
equal to 2048, the end time is the maximum record time (the number of
groups*the record period) of the file opened; when the number of groups
of the file opened is greater than 2048, the end time is the record period of
the file opened*2048.
Note: The following operations are valid only when valid record file is opened.
2. Set the analysis parameters
 Start Time
Press Start Time and use the numeric keyboard or the left/right direction
key and knob to set the start time of the record file analysis. The range is
from the record period of the file opened to the current end time.
 End Time
Press End Time and use the numeric keyboard or the left/right direction
key and knob to set the end time of the record file analysis. When the
number of groups of the file opened is less than or equal to 2048, the
range is from the start time to the maximum record time (the number of
groups*the record period) of the file opened; when the number of
groups of the file opened is greater than 2048, the range is from the start
time to the record period of the file opened*2048.
3. Execute the analysis
Press Analyze and the instrument will start to analyze the record file opened
according to the current setting. The analysis results include various statistic
parameters of the channel voltage, current and power, such as the average, VAR
and range.
