The test dials can be used to clock the meter. In other words, you can measure the volume of gas being consumed per hour. Knowing the volume lets you calculate the firing rate or input. In the adjacent example, you may time the meter and try to calculate the total gas consumption or you may click the [Calculations] button and go directly to the solution. It does not matter which test dial you use. However, the calculation will be more accurate when you use a longer period of time with a greater number of dial revolutions. For ease of calculation, you might wish to time the dial for 1 minute.

To measure the firing rate of a single appliance you must turn off the gas to all other appliances in the building. If any of those appliances have standing pilots you will have to relight the pilots when finished doing your test. Click the [Single Appliance] button and calculate the firing rate of the single apppliance before looking at the solution.
