Capture More Readings with MEX Prestarts

Capture More Readings with MEX Prestarts

Usage based Preventative Maintenance schedules in MEX work off an average reading calculated from the readings added into MEX. More frequent reading records improve the accuracy of an average and setting up prestarts to capture a reading when conducted, can achieve this.

Let’s start by looking at how MEX works with readings, in particular the Automatic average that is the driving force behind usage-based PM’s.

How does MEX Calculate an Asset’s Automatic Average?

First of all, a minimum of two readings must be entered into MEX before an Asset’s average usage reading may be calculated. Next, we take into consideration the value of the Average Using Last field in the Asset’s Reading details. This defaults to the last 6 Readings. Entering a 0 here will calculate the average over all readings.

Here is the formula:

Automatic Average Formula

The Automatic Average calculated will now be used in the Preventative Maintenance scheduling engine and work orders can be automatically created at the right times.

Capturing Asset Readings in Prestarts

Not only do Prestarts emphasize a high safety standard in your work place, they can immediately improve the efficiency of any usage-based PM schedules you have created for your vehicles, trucks and equipment by collecting more frequent readings.
