3.2 Menu mode "MENU"
Turn the power on with the switch on the battery module. After flashing the line "Gradiometer MG-
200", top line of the two-line display will read: "Sens. 1 (or 0.1) Filtr. 0 (or 1.2)" and level of the battery
charge ≤≤≤; the bottom line will display: "MENU"↓ - "OPERATION" →. Arrows show pressing of which
buttons will take you to the menu mode "MENU" or "OPERATION". Familiarize yourself with Menu and
tune the device for your search goals.
By pressing button 1 to switch into menu mode "MENU" and then button 6↓ you can scroll through the
following parameters:
Correction of "0". Correction of "0" is performed to compensate for the temperature drift. It means that
the readings will "drift" while the still device is warming up or cooling down. "Drift" is especially
noticeable during the first 20-30 minutes of operation, until the temperatures inside and outside the
device equalize. After this the "drift" either stops or is miniscule enough to control it by pressing from
time to time button 7 (reset device measurements to "0"). However if the drift is interfering with search
operation anyway, you should use automatic correction. While in "MENU" parameter "Correction of "0",
press button 4 "OK" and by pressing button 5→ choose the correction level from 1 to 10, which
sufficiently cancels out the drift. In most cases level 3 through 6 is sufficient. You shouldn't pick the level
higher than the one needed. Manufacturer's default setting is 3.
"Filtering" – is used to weed out the influence of metallic trash. With setting at 0.5 all anomalies smaller
than 0.5 meter in plan are ignored, at 1 – less than one meter, at 2 – less than 2 meters. With setting at
"0" – Filtering is turned off. Top line of display will show the current level of Filtering as F 0 when
Filtering is off, and F 0.5, F 1, or F 2 when Filtering is on. When exiting this setting through "OK" button
the setting will remain active for the following sessions of the device; when exiting through button
"MENU" – only during the current session.
Filtering works best during movement. During stops or slow movement filtering becomes less effective.
