Features

Sensor Model 9

• Measures the Frequency of Every Cycle
  • 1/24,000,000 Second Resolution = Frequency Measurement Precision of 6 Significant Digits or +/- 0.00015 Hz
  • Frequency Measurement at 2.5V Reference
  • Frequency Measurement at Zero Crossing
  • Zero Crossing Delta Measurement = Time Between +2.5V to -2.5V (used to measure Vp Amplitude)
• Internal EEPROM Stored Configuration
• Optional External EEPROM for Event Recording (on battery backup)
• For Control Output Set Points for Red/Green LED Indicator
• Data Transmission of Every Cycle Using RS232 in Streaming or Demand Text or Binary Data Modes at 115200 bps
  • Options for Step Mode Transmission after a set of cycles for Raw, Average, and Mean Frequency for each set.
• PHzMonitor Model 9 - Frequency Measurement Modes of Operation Details
