EnCalcOU calculates the cost of oil, allowing both the real cost based on tank readings and forward prediction based on the readings and elapsed time. The results can be saved to a log file for later analysis. The software can cope with different shaped tanks, work in volume or depth of oil, varying tax rates plus fixed charges enabling most charging models to be handled. It will also calculate the amount of CO2 generated and predict when the tanks next need filling. EnCalcOU is part of the JSutils group of program utilities which have a theme of energy conservation.

Entering invalid data will cause an error pop up to appear explaining what is wrong when the calculate or Save Data buttons are clicked. These errors must be resolved before the calculate or save defaults functions will work. If an internal software error occurs data will be written to the log file if possible and an error number will be displayed. Any errors of this type should be reported since they indicate a bug.

Set Up
Before using the software set up how you want to use it. Set the shape plus capacity of the tank(s) and if using depth measurements un tick the volume tick box and set the depth of the tank(s). Set the VAT/Tax rates for oil and deliveries., you must set both rate which can be different or leave both blank.

First Use
Set Tank Reading Date 2 to the current date and the Tank 2 Reading(s) to the current value(s). Set Tank Reading 1 Date to 3 days earlier than the current date and the Tank Readings to 0. Set Delivery Date 1 to the current Date and add the oil value to Delivery 1. Click Calculate and then Save. Doing this sets up a record of the starting point for oil left and it's value. If no costs are entered then the residual value of the oil left will not be saved and no costs will be calculated in subsequent calculations.

Currency And Date Formats
This is defined by the settings in the computer Regional Options which can be accessed via the Control Panel. The currency symbol reflects the settings in the Currency Tab. The date format in the log file reflects the Short Date format setting in the Date Tab. The currency or date settings can be changed with the software running. Currency changes will be reflected next time Calculate. Reset Feds or Clear are clicked. Date format changes will be impactful for the next new calculation. Entering a different currency symbol to that selected in the Regional Options Currency Tab will be treated as an error.

Depth To Volume Conversion Errors
When using depth measurements the depth is converted to volume, because volume is measured in whole gallons or litres there may be a small conversion error due to rounding. This is very small and is only noticeable when tank readings are small and the amount left is half the depth at the start.
