Checking the values you have set up for the Maximum Digits for your meter types is especially important as your meters approach their maximum number of digits and roll over. UtilAbility uses these values to calculate the proper usage when your meters roll over. If any of these values are not set correctly, UtilAbility may not know how many digits a meter has and will not be able to determine the correct usage when it has rolled over.
As an example, let’s say that the Maximum Digits for your 1 meter type is set to 2. From this setting, UtilAbility would know the maximum value for any 1 meter would be 2 digits or 99. After 99, the meter would roll over and the readings would start again from 0. For example, if your previous reading was 98 and your new reading is 2, then UtilAbility will calculate your usage as 4. (99, 0, 1, 2)
You can access the Maximum Digits for each of your meter types in the Meter Types Maintenance form. If you find that any are set incorrectly, simply edit that meter type, modify the Maximum Digits and save your changes. If you have meters with different Maximum Digits, you will need to have a separate meter type for each variation. When you set up your meters in the Meter Information Maintenance form, you will set their Maximum Digits values by specifying their meter types.
Along with rolled over meters, there are other things that are considered when calculating usages from your readings, such as maximum usage thresholds and reverse readings. Fortunately, UtilAbility considers these things for you. As long as you have their Maximum Digits values set properly and you enter your readings correctly, UtilAbility will calculate your usages appropriately.
Remember, as always, please contact our support staff should you have any further questions or need more help checking your Meter Types Maximum Digits values.
