8545-M838-O1 Rev D 825 Installation & Technical
EVENT COUNTERS
A Category 1 Event Counter is provided on the 825 with two counters that increment when a
change is made to features that are required by NTEP or OIML to be sealed. One counter is
designated for calibration parameters and one is designated for configuration changes as
required in NCWM Publication 14, 2007. Each event counter has a capacity to record 999
changes. The data for the counters is maintained in non-volatile memory and can be viewed
by a weights and measures inspector. When selected, the display will show the number of
changes and the date and time of the last update to the Calibrate and Config counters.
