12.4 Non-Vibration unit analysis types
Non-Vibration unit analysis includes:
• Peak to Average Ratio
• Average to Minimum Ratio
• Kurtosis
• Skewness
• Synchronous Phase
These analysis types produce non-unit ratios or specific unit types such as degrees of
phase. Measurement Unit Type will not apply to these parameters.
12.5 Set DC offset
For thrust probes, the input channel is defined as a DC Process input. Set the DC offset so
that the thrust reading may be zeroed.
Procedure
1. Use a DC voltmeter (or the DHM program) to measure the DC voltage as seen
directly on the inputs.
