OPERATION MANUAL - Scintrex

• the system applies a self-calibrating ADC• corrections for tilts and long-term drift are made every five seconds duringthe reading.• a statistical rejection criterion is used to discard any noise spikes.• a tide and temperature correction is applied at the end of the reading.When a measurement is completed, the gravity reading is stored in thememory along with the following nine other variables:1. station number2. standard deviation of the mean of the five 5-second samples3. tilt X4. tilt Y5. sensor temperature6. tide correction applied7. reading duration8. number of rejected samples9. time of start of reading10. terrain correction applied11. raw data if enabled.All current and stored data can be viewed on the VGA screen by using theRECALL feature on the keypad.Additional information can be entered by way of notes at the time ofmeasurement for recording in memory.The standard Flash memory stores approximately 170000 readings as definedin Chapter 6, “Reference Information”. The memory is protected againstbattery failure.Other information is also generated and is accessible through the display,including time, date, setup parameters and CG-5 options.The instrument is equipped with RS-232 and USB interfaces. This enablesdata from the memory to be accessed through a connector on the instrumentfront panel.TheoryB-5CG-5 Manual - part # 867700 Revision 2
