Page 2: Technical Specifications
1 Introduction The NEMTEK Fence Meter measures the electrical condition of an electric fence. By holding the meter against the fence wire the meter will turn on automatically when it detects a fence voltage. The fence voltage, current and the direction of a possible fence fault will be displayed on the LCD. - Page 3 3 Warnings 1. This product is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the product by a person responsible for their safety. 2.

5 Operation Holding the meter • Grip the fence meter tightly in your hand, taking care not to grip too close to the electric fence wire, contact strip or LCD screen. • This meter makes use of capacitive coupling between the user, meter... -
Page 6: Taking A Measurement
• If there is a voltage pulse in excess of 150V present on the wire, the Fence Meter will turn on automatically and display the fence voltage, current and if present, the direction of a possible fault (see screen layout in section 5). - Page 7 If the current in the fence wire is less than 2A, no fault direction arrows will be shown. • If the Fence Meter does not detect an energizer pulse for 10 seconds, the meter will automatically switch off. • Measurements taken in close proximity (less than 1m) to the energizer might not be accurate.

Page 8: Battery Replacement
Battery Replacement • If the battery symbol is displayed along with the measurements, the batteries will need replacement soon. • If only the battery symbol is displayed, the batteries need to be replaced before any measurements can be made. • The batteries (2 x AAA 1.5V) can be replaced by loosening the 6 screws at the back (leave the screws on the belt clip) and opening the meter. -
Page 9: Finding A Fault
6 Finding a Fault The two most common faults in an electric fence installation are an open-circuit (wire break, poor connection etc.) fault or a short-circuit (insulator breakdown, vegetation, live and ground wire touching etc.) fault. In order to facilitate the fault-finding process, current and voltage measurements at regular points along the fence when in a healthy condition should be recorded for comparison when a fault occurs. - Page 10 • Take a measurement at regular intervals along the fence, while moving away from the energizer. • When the measurement shows a significant drop in voltage and current, the fault should be between the current and the previous measurement points. •...

Page 11: Short-Circuit Fault
Short-circuit Fault • Start as close as possible to where the high voltage (HV) leads from the energizer connects to the electric fence and take a measurement on the live wire. • The fence current will be significantly higher compared to a healthy fence. - Page 12 • When fault finding parallel fence wires, follow the wire with the highest current reading.
