Resetting the Security Code to a Null

In case a CAL Security Override is required at any time:

• Create a text file with the defined name “CalSecureOverride.txt” in an

external USB flash drive at the root directory. This file should be

empty.

• Connect the USB drive to the counter front panel USB port.

NOTE Where USB usage is not allowed, FTP can be used to input the file

into the instrument.

• Power the instrument off and back on.

– At startup, the counter will detect the “CalSecureOverride.txt”

empty file on the USB flash drive and there will be a message on

the front panel display: “CAL Security Override file found. Turn

OFF CAL security?” which must be responded to within 10

seconds time.

• If the operator responds to the message (by pressing the YES soft key),

the counter will turn OFF the CALibration SECurity STATe.

– A front panel message “CAL Secure State is turned Off” will be

displayed.

• As the Calibration secure state is now OFF (i.e.the counter has been

un-secured) the operator can enter a new Secure Code.

• At this point, the operator can either turn the Calibration secure state

back ON or leave the box unsecured, as desired.

• The “CalSecureOverride.txt” file is automatically erased from the

USB flash drive, regardless of the user action or non-action.
