The ODU shell does not provide an electrical contact to the corresponding socket. The MFS pre-amplifier has a resistance of ~30 Ohm and our input on the ADU side for H ~20 kOhm. The cable we use has twisted pairs ("Input +"" x "Sensor GND" ?). "Input-" is connected to GND |br| Pin 3 toggles the chopper. You need 5 or 12V. Pull up the gate with 12V and pull down with GND. |br| pull up -> pull down == chopper off |br| pull up -> pull down -> pull up == chopper on (there is no need to hold the 12V to keep the chopper on) |br| Switching does not need extra requirements since there is almost no current flow while switching. |br| You can order a suitable cable plug from Metronix or directly from the manufacturer ODU in Germany (www.odu.de) The part number of the plug is ODU Minisnap Series K S22KON-T10MJG0-7000 |br| You may also need a strain relief streeve ODU (bend protection, green) part.no. 702.023.205.965.060 |br| Connect to another Logger ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The ADU-08e has a true differential input. We connect the Sensor GND (Pin4) of the ADU with the MFS-06e sensor GND (Pin4) by the sensor cable. The negative input of the ADU (Pin8) is connected to the output - (Pin8) of the magnetometer. The positive input+ of the ADU (Pin7) is connected to the positive output+ of the magnetometer (also here pin 7). By this means we avoid ground loops and obtain a pseudo differential behavior. The reason why you do not see a difference in having ground connected or not when switching the chopper signal is that we provide a 100kOhms pull-down resistor on the control input against sensor GND. Hence, when switching the supply voltage to the control input you get exactly the relay switched to the correct position. The supply voltage is referred to sensor ground. Assuming your data logger has a differential input I recommend to provide the same cabling as described above: Magnetometer Pin 7 to positive input of your instrument |br| Magnetometer Pin 8 to the negative input of your instrument |br| Magnetometer Pin 4 to the Sensor GND of your instrument |br| Magnetometer Pin 3 to a switch which provides positive supply voltage to switch chopper on |br| The +12V and -12V supply voltage of the sensor must be referred to sensor GND of your instrument |br| The cable should be twisted pair type: Sensor output +/- must be twisted. +/-12V and chopper and sensor GND can be twisted. If you use it CAL+/- must be twisted, too. If you do not use it do not connect it at all.

Howerver when the transmission is pulsed (like the old mobile phones did) you can get significant distorions. |br| Mostly the DC/DC converters (power stabilized 12V adapter) can cause trouble. |br| This is mostly also the noise source of **solar panels**. |br| There is nothing to do but testing. Leutron E-Field Protection ---------------------------- For a better protection against over voltage from the E-Field we recommend to use the Leutron E-Field protection. |br| The Leutron E-Field protection is a small box which is connected between the electrode and the ADU. |br| .. image:: /media/faq/E-Line_Protection.jpg :width: 50% :align: center opened: .. image:: /media/faq/E-Line_Protection_2.jpg :width: 50% :align: center Leutron MP Base 1x2-R HF, No. 97 01 02 *and* Leutron MP 1x2 5 V-170-HF ST, No. 97 10 56 |br| Contact a local dealer or Leutron directly: `www.leutron.de `_ |br| You need **two** of them, N-S and E-W. |br| Example - usage on a field site we put the modules in a little box: .. image:: /media/faq/leutron_in_box.jpg :width: 50% :align: center You see 2 times a blue cable: North Line and South line; |br| The yellow and green bridges the ground. |br| During this comparison the second module was not used (the third will be never used but is unfortunately on the picture) . |br| For field measurements the second module will be connected to the East and West line the *same* way. |br| **You have to shorten the ground line** between both modules. |br| We have tested the modules in the laboratory and in the field. There are no visible differences.
