CALIBRATION AND SETUP
Security Seals
A Category 1 Audit Trial is provided on the Model 225 with two event 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. Refer to
the VIEW AUDIT TRAIL COUNTERS section of this manual for more information.
If your local metrology laws require the use of physical sealing, the Model 225 has been
designed with two types of security seals. One seal, a calibration jumper prevents
unauthorized access to the calibration adjustments while the second seal (lead-wire) prevents
the rear panel from being removed from the indicator to gain access to the jumper.
NOTE! The calibration seal jumper (P6) is located on the main printed circuit board and can
only be accessed by removing the rear panel of the indicator.
The following setup parameters CAN NOT be changed with the calibration seal jumper (P6)
installed.
