The app is split into four parts: the Electrical Safety Tests, a Multimeter Guide, an Ohm's Law Calculator and an Ohm's Law Guide.
★★★ Electrical Safety Tests ★★★
The app will show you how to carry out all of the tests from start to finish to help you make sure the boiler is completely safe. The tests should be completed after an installation (before switching on the appliance) or before carrying out any work on an existing boiler. Each test contains easy to understand images to make it much simpler to follow. Many electrical faults can be identified from the tests and the Fault Isolation page should help you to find the cause.
There are six parts, these are:
• Before Starting
• Earth Continuity Test
• Short Circuit Test
• Resistance to Earth Test
• Polarity Test
• Fault Isolation
We asked someone who had never used a multimeter to use the app and they were able to carry out the tests with ease!
★★★ Multimeter Guide ★★★
To help you to get a better understanding of how to use your multimeter, this app includes a multimeter guide. It consists of the following parts:
• Multimeter types
• Multimeter settings (those settings needed when working on boilers)
• SI Prefixes (to help you understand the multimeter results)
• Know your multimeter (so you will know what to look for on your own multimeter)
★★★ Ohm's Law Calculator ★★★
Our very popular Ohm's Law Calculator is included in this app. It's extremely easy to use; enter two known values, press the 'Calculate' button and the other two values will be entered instantly. If more calculations are required, each single entry box can be cleared using the corresponding 'X' button or press 'Reset All' to clear all four boxes.
★★★ Ohm's Law Guide ★★★
If you're a beginner with electrics the Ohm's Law Guide will help to give you a better understanding of the calculations. The first two pages will explain Ohm's and Watt's Laws and the other four pages contain every possible formula for conversions between voltage, current, resistance and power.
A complete Ohm's Law reference guide you can take with you - wherever you go!
