Power Meter Calibration Software [free software]
This software automatically calibrates a power meter (WT series) using YOKOGAWA's AC Power Calibrator LS3300 and 2560A Precision DC Calibrator. Load a CSV format file describing calibration points in advance to control the LS3300 or 2560A so that reference signals are output according to the calibration points. For the following instruments that can be controlled with this software, set the range of the calibration target instrument remotely for each calibration point to read the measured values automatically. You can save a calibration result in a CSV format file and create a test certificate.
*: For a calibration targets other than WT100, WT200, WT300, and WT300E series, you cannot automatically set the measurement conditions and load the measured values.
**: CSV format file (comma-separated)
1．Automation of calibration
Automating calibration allows engineers to focus their energy on more time-sensitive tasks.
Example: WT310E Calibration point AC 52 points
2. Pass/fail judging function
This function judges pass/fail of a calibration value according to a set threshold and displays one of the three judgement results: Pass (Blank), Warning, Fail.
- Blank (Pass): The ratio of error to tolerance has not exceeded the threshold.
- Warning: The ratio of error to tolerance has exceeded the threshold.
- Fail: The ratio of error to tolerance is 100% or more.
3. Calibration definition file
Sample files are provided for each WT series model.
Calibration points can be created arbitrarily as a calibration definition file.
4. Function to calibrate desired points
You can also choose certain desired points from among the created calibration points.
5. Wizard function
For calibration patterns and instrument connection methods, operation instructions and wiring diagrams are shown on the screen.
6. Saving calibration results in files
You can save a calibration result in a CSV format file and create and print a test certificate.
(This software comes with a sample of Excel macros that create a test certificate.)
7. Function to restore setting values
Calibration automatically changes the measurement conditions including the measurement range.
To revert to the original settings, you can save the settings before calibration and reset them after calibration.
