Avoid using this equipment around active military installations and airports or where there may be other devices that may hamper the signals received. Radars for aircraft, boats and weather reporting may lower the units capabilities. OKM GmbH www.okmmetaldetectors.com... -
Page 10: Voltage / Power Supply
Curved or round objects should be a sign of alarm, especially if buttons, rings or little pegs can be identified or felt. The same applies to recognizable ammunition or bullets and shells. Leave that stuff alone and where it is, do not touch anything and, most importantly, do not take any of those items home OKM GmbH www.okmmetaldetectors.com... - Page 11 Moving such an object may cause those crystals to produce friction, leading to an explosion. If you come across such relics, mark the place and do not fail to report the find to the police or proper authority. Such objects always pose a danger to the life of hikers, walkers, farmers, children and animals. OKM GmbH www.okmmetaldetectors.com...

Page 48: Basic Information
Your chosen scan field resolution (distance between scan points) must match the object's • dimensions. This means you can only detect underground anomalies if you scan right on top of the hidden targets as well as the surrounding ground. OKM GmbH www.okmmetaldetectors.com... -
Page 49: General Measurement Procedure
Electrodes (electrodes with red socket) and the resulting voltage is measured with the two Voltage Electrodes (electrodes with black socket). By increasing (or decreasing) the distance of the Power Electrodes step by step the measure depth also increases (or decreases) accordingly, as shown in figure 7.3. OKM GmbH www.okmmetaldetectors.com... -
Page 50: Figure 7.3: Power Injection Depth Depends On Electrodes Distance
Figure 7.4: Available Scan Modes An active measurement is always injecting electrical power into the underground before measuring the voltage between the Voltage Electrodes whereas a passive measurement is only detecting natural voltage without any power injection. OKM GmbH www.okmmetaldetectors.com... - Page 51 This option is used to measure a single scan point only. This is mostly used to do some quick test measurements on your scan field to find potential places where you could do a more complex measurement. OKM GmbH www.okmmetaldetectors.com...

For our example it will be as follows: OKM GmbH www.okmmetaldetectors.com... - Page 53 You have to move the Voltage Electrodes (black socket) • inwards to another cable marker (several cable markers might be skipped). This will be necessary if the measured voltage is too high. OKM GmbH www.okmmetaldetectors.com...

Page 56: Setting Up The Voltage Measurement
The voltage measurement equipment consists of the Controller with Voltage Cable Drums as well as the Voltage Electrodes. All those parts are equipped with black plugs or black sockets. This Voltage Line is used to measure the natural voltage (passive scan) or the generated potential difference (active scan) of the Power Line.
