Zero Minimum and maximum values

I have a log of bogus values for min and max.

I had a system crash and when I rebooted and WD got the stored info from the WM II it gave a lot of very odd values like 148 KM per hour winds (no hurricane here though), THis has happened in the past as well and as a result my data of all min and max has many errors.

Is there a way of zeroing the complete mins and max. and maybe even zeroing the total station so that there would me new data starting today?

What would be causing this to happen?

it will be the data extraction at start up routine,.,and the data getting out of sync…maybe when you have a full data logger and it wraps around

you can reset all that data via action, reset selected all time records, reset daily extremes, etc
and you can also then re- enter your known extremes via action enter your own all time records
once tidied up, set up the backup facility in wd, so that you have a daily backup of the settings file that has all that data, i.e wdisplay.ini
