 How do I setup the Keyspan 4 channel Serial to USB Converter to download the 856 on a Windows 7 machine?
1)Download the latest MagMap2000 software from our site. http://www.geometrics.com/geometrics-products/geometrics-magnetometers/download-magnetometer-software/ 2) With the Keyspan connected and Win 7 drivers loaded, right click on My Computer and then left click on Properties. Click the Devi ...
- How does Magnetometer noise vary with sample rate?
Sensitivity is given as a frequency bandwidth product or nT/rt Hz RMS. This value is valid for ALL sample frequencies or sample rates. Sensitivity for the 858 and 859 is 0.008nT/rt Hz RMS Sensitivity for the 823 and 882 is 0.004nT/rt Hz RMS Noise levels can also be given as Peak-to-Peak number ...
- How do I run MagLog and MagMap in my Windows 7 machine? Does it matter if it is 32 bit or 64 OS?
Microsoft recently released 32 and 64 bit versions of their new operating system Win 7. We like the OS and realize that many people will be upgrading from Vista or XP to take advantage of the new features. MagMap and MagLog are compiled for the 32 XP OS. We are in the process of recompiling t ...
- Will my magnetometer find Gold?
From our experience there are basically three types of “gold” occurrences: 1) disseminated gold in ore, 2) placer gold that is found in river sediments and 3) treasure which is gold that has been concentrated by human activity and then been lost or hidden. Magnetometers are used to f ...
- What version of MagLog do I need, MagLogLite or MagLogPro?
We suggest that you download the manual for the MagLog software which can be acquired here. ftp://geom.geometrics.com\pub\mag\Manuals You may also download the MagLog software in install it from this site ftp://geom.geometrics.com/pub/mag/Software If you would like to try the software out, w ...
- Will the magnetometer find gold?
1. There are basically three types of "gold": disseminated gold in ore, placer gold and treasure. Magnetometers are used to find disseminated gold by it association with mineralized zones which contain magnetite or other magnetic minerals. It is often used in conjunction with airborne EM to ...
- Difference between our standard Cesium Magnetometer and the SX model
Clarification regarding Geometrics standard magnetometers, SX versions and the US Govt. export regulations In this brief review magnetometer specifications are given in terms of both nT/sq-rt-Hz RMS and in Peak-to-Peak (P-P) noise values as both forms are often used to describe instrument perf ...
- Depth of exploration
In a general sense, the exploration depth of the magnetometer's readings are unlimited. It is certainly sensitive to the Earth's field and this is generated in the Earth's Core, some 5000 km beneath our feet. But for practical purposes, the depth of exploration is determined from survey resu ...
- Estimating Depth to basement
Magnetic surveying as a means of estimating depth to basement requires the collection of a data set that can be processed to yield the average radial power spectra as a function of survey position. The assumption here is that the basement rocks are much more magnetic that the overlying sediment ...
- Exploration for Iron Ore
One of the primary uses of our portable (land) magnetometers is mineral exploration. And iron ore is one of the easiest targets because of its magnetic properties. Because of this, magnetometer surveys are almost always part of the initial phase of any iron exploration program. Briefly stated ...
- Thoughts about attaching a magnetometer to a non-ferrous sled or frame.
Regarding deployment of magnetometers on conductive sleds or carts near power lines: we expect that the elevated field readings you may observe under power lines are a result of AC induction in the aluminum sledge you are using as the tow vehicle. The reason that you see a DC effect from an AC ...
- Why you need a Base Station
Your need of a base station depends on the objective of the survey. If one is performing a geologic survey to investigate deep structure (exploration for mineral deposits, oil/gas, geology) then the wavelengths of the "target" body are typically “long” (long in meters, therefore lo ...
- Magnetic properties of Stainless Steel
All of the 300 series stainless (austenitic) steel is considered to be weakly magnetic in its annealed state. These include the common 303, 304, and 316 alloys. 18-8 stainless is another name for 304 stainless (18% chromium and 8% nickel). Surprisingly it is the nickel content in the stainle ...
- Cesium Magnetometer Product Certification
The attached document at the bottom of this page can be used to prove the Hazardous Material Status of our Cesium Magnetometers.
- Why does the signal strength vary with the magnetic field in high gradient locations?
If the sensor is in a very large gradient field such as inside a building near some steel objects, then the high gradients (change of field with distance) causes different parts of the internal sensor components to respond to different fields, making the sum signal smaller. This only takes pla ...
- Magnetic field strength versus signal to noise ratio.
The Cesium magnetometer is so fast and has such a large dynamic range that it can be considered to be either “on” or “off”. What this means is that if the sensor active zone is in the earth field vector (approximately 70 degrees in each “quadrant” of 90 deg ...
- What is the unit of the 'Signal' ?
The signal strength is in arbitrary units, it is not in volts or some other unit. We use signal level to compare one system to another, to make sure it is operating correctly and getting good data.
- What is detection range of the magnetometer?
This is a very common questions and our best answer is to have you read the Applications Manual for Portable Magnetometers which is available from our website. To give an idea, the rule of thumb is that 1 ton of steel will give 1nT at 100 ft. The distortion caused by the steel in the earthR ...
