Function The BoreHole Gradiometer (BHG) responds when the magnetic field strength measured at the two sensor elements inside the Sensor housing are different. This difference is measured in “Differential Milligauss” and is reported to the user via the LCD display and the audio speaker. A headset may be used in noisy environments and will disable the speaker when connected. The RS-232 interface allows control and recording using a personal computer with a serial COM port.
Maintenance Operation Keep the unit as clean as possible, especially the Electronics keypad panel. Do not use an abrasive cleaner on the keypad overlay or the LCD lens. Connect the sensor to the electronics using the sensor cable before turning the system on. Press the green ON button to turn on the BHG . To turn OFF press the red OFF button. The RS-232 interface cannot be used to turn the BHG on or off. The Titanium encased sensor has no user serviceable parts.
Connections The headphone jack has a water resistant cover. Lift open to plug in a stereo phone plug to listen with a headset in noisy environments. Replace a blown fuse with a 1/4 amp slow blow.
