3.5.1.4 SETTING OR CHANGING A PASSWORD KEY
As a security feature, the instrument can be configured so that a password key is required to ac-
cess the Engineering Mode configuration function. The password key can only be set by the Hand
Held Configurer, or the 53HC3300 or 53WS5000 software packages via a PC, or the SUPERVI-
SOR-PC, and not by the instrument front panel push buttons. A password key is a special data
type (Q1) that is displayed or configured just like any other data type using the Hand Held Config-
urer. The value assigned to a password key must be an ASCII numeric string up to 10 characters
because only numbers (0-9) are permitted as KEY? input characters by the instrument. To re-
move a password key completely, press CTRL 0 (hold CTRL and press 0 ), then ENTER.
3.5.1.5 STORAGE CARTRIDGE TRANSFER
The procedure to save or load the database or calibration constants of an instrument using the
HHC with storage cartridge (part number 698B182U02) is as follows:
1. Insert the cartridge containing the desired database in the HHC. The cartridge is inserted by
placing it into the recess at the back of the HHC with the cartridge label facing outward and up,
then sliding the cartridge down until it is firmly seated. When loading to the instrument, verify
that the write protect switch (when present) on the cartridge has been pushed to its outside po-
sition. When saving to the cartridge the write protect switch must be toward the inside.
2. To initiate the TRANSFER operation, press T at the command entry point. The following menu
appears:
MEMORY TRANSFER
F1-TO CONTROLLER
F2-FROM CONTROLLER
3. Press either F1 or F2 to select the desired operation. Pressing CTRL C aborts the operation.
Depending on which selection is made, one of the following two menus is displayed:
1. If F1 is selected, the following menu appears:
F1-CALIBRATE
F2-DATABASE
F3-PROGRAM (not applicable
for this instrument)
Based on which selection from this menu is made the following operations can occur:
•
F1-CALIBRATE: This selection copies the calibration values of the standard analog in-
puts and outputs to the instrument. These are values that were previously saved to the
storage cartridge with a memory transfer from the instrument. This transfer takes approxi-
mately 1 second.
•
F2-DATABASE: This selection copies the database, less the calibration values, and the
assigned instrument address to the instrument. Transfer takes approximately 12 sec-
onds.
•
F3-PROGRAM: This selection is not applicable for this instrument.
