I have an application that schedules Preventive Maintenance for equipment. Most of the equipment uses an hour meter. I log in the hour meter reading into a table and use that along with the last time the PM was done to schedule the PM's. From time to time a meter will break and the Maintenance person will replace it. We don't have a way to "run up" the new meter so it starts at 0. Now the problem is how to add in the last good meter reading to the file each time a new meter reading is taken. Does any one have any thoughts on this? Should I have a file with the broken meter reading and add that to any readings taken some how???


Thanks
