How are Electronic Testers Used in 2-wire Systems?

A graphic illustration of the places where electronic testers from locators to meters can be used to test and troubleshoot 2-wire decoder systems.

Tips on Test Settings for the Pro93 and Pro95 Clamp-meters.

- The sensitive milliamp clamp-meters from Armada have a low pass 50/60 Hz input filter that should be
turned on. You may see differences between meter models if the filters aren’t selected.
- To use the Pro95’s full 600 kilohm resistance range press Beep/Ohms button to turn off the beep
test symbol. In the beep-only mode the meter will only display low resistances or 'OL'.

Quick-testing a System from the Irrigation Controller

Use an electrical multimeter or an irrigation tester to do an quick irrigation system health check without leaving the controller.

Tracking Plastic Pipe with a Locator and a Fish Tape

It is possible to track non-conductive items like plastic pipe by inserting a metal ‘fish tape’ into them and tracking the path of the tape with a conventional wire locator. This is an alternative to the more effective Pro65.

Recognizing Valve Brands by Solenoid Resistance

You can tell a number of things about an irrigation system using an ohm-meter right at the
controller. One useful test is to verify that all of the solenoids are alike, are AC or DC operated
and even who manufactured them. You can use the ohms function on the Armada Pro50 to
do this or any number of electrical multimeters.

Use the "Low Pass Filter" Setting on Milliampere Clamp-meters

The sensitive milliamp clamp-meters from Armada have an input filter that should be set for measuring current in lighting and irrigation systems. Using the filter will make measurements most consistent.

How To Get The Most Out of The Inductive Trace Mode In Your Locator

Several Armada Technologies locators have an “inductive tracing” mode that allows the tracking of wire, pipe and cable without direct connection. Here are some tips to help use this safe and flexible technique.

Tracking Wires In A Low Voltage Lighting System

Cable locators can be great for tracking lighting system wiring. Here are some best practices for
doing it quickly and safely.
