Enter a 4-digit password from the keyboard; the display will show the message
NEW PASSWORD STORED! for two seconds and then revert to the UTILITY menu.
If any ke
ys other than 0-9 are pressed while entering the password the message
ILLEGAL PASSWORD! will be shown.
The password is held in EEPROM and will not be lost
when the memory battery back-up
is lost. In the event of the password being forgotten, contact the manufacturer for help in
resetting the instrument.
Password Access to Calibration
With the password set, pressing calibration… on the UTILITY screen will now
show:
ENTER PASSWORD
----
When the correct password has been entered fro
m the keyboard the display changes to
the opening screen of the calibration routine and calibration can proceed as described
below. If an incorrect password is entered the message INCORRECT PASSWORD! is
shown for tw
o seconds before the display reverts to the UTILITY menu.
Changing the Password
With the opening screen of the calibration routine displayed after correctly entering the
password, the password ca
n be changed by pressing the password… soft-key and
following t
he procedure described above. If the password is set back to the factory
default value 0000, password protection is removed.
Calibration Routine
The calibration procedure is entered by pressing continue on the opening calibration
screen; pressing exit returns the display to the UTILITY menu.
Pressing tests… calls a menu of basic hardware checks used at production test; these
are largely
self-explanatory but details can be found in the Service Manual if required. At
each step the display changes to prompt the user to adjust the rotary control or cursor
keys, until the reading on the specified instrument is at the value given. The cursor keys
provide coarse adjustment, and the rotary control fine adjustment.
Pressing next increments the procedure to the next step; pressing CE decrements
back to the previous step.
Alternatively, pressing exit returns the display to the last
calibration sc
reen at which the user can choose to either save new values,
recall old values or calibrate again.
The first two displays (CAL 00 and CAL 01) specify the connections and adjustment
method. The next displa
y (CAL 02) allows the starting channel to be chosen; this allows
quick access t
o any particular channel. To calibrate the complete instrument choose the
default setting of CH1. The subsequent displays, CAL 03 to CAL 55, permit all
adjustable param
eters to be calibrated.
