Saving Data

Pressure, current, and voltage measurement data, leak rate measurement data, and transmitter or
pressure switch calibration data can be saved to CSV files.
Saving Pressure, Current, and Voltage Measurement Data
There are two ways to save measured values.
Save
Measured values are appended to a file each time you press the Save function key. The file name
is SAVEXX.CSV where
SAVE: A common name given to files saved with the save function
XX:
Data is added to the same file until any of the following conditions is met.
• When a setting is changed
• When the voltage measurement range is changed
• When the number of save data points exceeds 2000
• When the power is turned off
Logging
The specified number of data points are saved at a preset sampling interval. The file name is
LOGXX.CSV. A file is created each time logging ends.
LOG: A common name given to files saved with the logging function
XX:
For Leak Rate Measurement
For leak rate measurement, measured data is added to the file each time a leak test finishes. The
file name is LEAKXX.CSV where
LEAK: A common name given to files saved with the leak function
XX:
Data is added to the same file until any of the following conditions is met.
• When a setting is changed
• When you exit from a leak test
• When the power is turned off
Pressure Transmitter and Pressure Switch Calibration Data
Calibration data before and after transmitter adjustment is saved to files with identifiable names.
Calibration data is added to the files every time a calibration is performed at the calibration points.
The file names are as follows:
Calibration data file before adjustment:
Calibration data file after adjustment:
MS:
SW:
xx:
F:
L:
y:
The calibration group number remains the same as long as the calibration target information or
calibration procedure remain unchanged. Therefore, the calibration data files of the same transmitter
before and after adjustment will have the same calibration group number.
