•
CLR.LIN (Clear Linearization Points)
Select to view linearization setup and select linearization points to clear. Refer to CLR.LIN (Clear linearization)
section 8.3.2 for more information.
•
DIR.ZER (Direct Zero Calibration)
Select to enter the mV/V value of the zero calibration directly. This feature is used to enable approximate
calibrations to be performed in situations where a standard ZERO calibration is impractical (e.g. calibration on a
partially filled silo).
•
DIR.SPN (Direct Span Calibration)
Select to enter the mV/V value of the full scale capacity of the scale build. This feature enables the instrument
to be calibrated based on the rated output capacity of the load cells rather than using test weights. The
accuracy of this method is limited to the accuracy of the published load cell ratings.
•
FAC.CAL (Restore Default Factory Calibration)
Select this choice to restore default factory calibration. This restores all calibration critical settings in the BUILD,
OPTION and CAL menus back to factory defaults. The instrument will prompt with Cont. N. Press to
change to Cont. Y and to continue. If Cont. Y is chosen and then or is pressed, the
instrument will display DONE to indicate that the operation has been completed.
7.4.4 SPEC (Special Settings Menu)
Settings within this group control features including passcodes, key locking, key functions and display settings.
•
SAFE.PC (Safe Security Passcode for Digital Setup)
The SAFE.PC (Safe Passcode) allows partial access to Digital Setup (ie. only non-calibration/trade critical
settings can be changed). For the Safe Passcode to have any effect, the FULL.PC passcode must also be set.
The default passcode setting is 000000 that allows free access. Any other number will enable the passcode
functions and restrict access. Refer to Passwords section 6.6 and Accessing Setup section 7.1 for more
information.
•
Range 000000 to 999999
•
Default: 000000
•
FULL.PC (Full Security Passcode for Digital Setup)
The FULL.PC (Full Passcode) can be set to restrict access to Full Digital Setup. This passcode is used to
prevent unauthorized or accidental tampering in the instrument setup. The default passcode setting is 000000
that allows free access. Any other number will enable the passcode functions and restrict access. Refer to
Passwords section 6.6 and Accessing Setup section 7.1 for more information.
•
Range 000000 to 999999
•
Default: 000000
è
It is important to note that when restricting Full access to Setup the passcode must not be forgotten. It is only
possible to circumvent the passcode at the factory. Care must be taken when setting the Full Digital Setup
Passcode to ensure that the instrument does not become permanently locked.
•
KEY.LOC (Front Panel Key Locking)
This item allows individual keys to be locked and unlocked. The display shows a dash (–) to indicate that a key
is locked (inactive) or characters for each key that is active (ie. the characters P12345 display). The letter P
represents the key and the numbers 1234 and 5 represent the remaining operation keys. The
operation keys are numbered from the left with the key being number 1.
Note: When the key is locked, the instrument cannot be turned off from the front keypad.
•
Default: P12345 - All keys are unlocked (active)
•
KEY.FN (Key Functions)
The function of the keypad key can be selected here. Refer to Special Functions section 11.0 for
details of the available key functions.
