2.10 SET-UP MODE
Set-up mode enables the allocation of set-piece (known sample) values of
different lacquers to the 99 channels in custom channel mode. It also
enables the probe to be exactly matched to the instrument by cancelling out
stray admittance created by the probe and its leads, this latter function is
known as calibrating the probe.
To prevent unauthorised access to the set-up values a passcode must be
keyed in before set up mode is enabled. The passcode is initially set to 9963
but may be
changed to any 4 digit number. The passcode will always be reset to 9963 if
a master reset is performed.
2.11 ENTERING SET-UP MODE
To select set-up mode the
CALIBRATE
and
LACQUER NUMBER
keys must
be pressed simultaneously. This will cause the SET-UP indicator to
illuminate and the word PASS displayed.
The four digit passcode should now be entered and if keyed in correctly the
unit will be in set-up mode. If entered incorrectly the instrument will drop
back to measure mode.
2.12 CHANGING THE PASSCODE
To change the passcode it is necessary to first enter set up mode using the
current passcode, then simultaneously press
LACQUER NUMBER
and
CALIBRATE
again. The display will show question marks with P1 in the
lacquer number display. The new passcode is now entered (4 digits) and the
lacquer number display will change to P2. The new passcode must now be
entered again to confirm it and it will become effective.
If a different passcode is entered the second time (whilst P2 is in the lacquer
display) an error will be indicated and the passcode will not be changed.
2.13 CALIBRATING THE PROBE
It is essential to calibrate the probe if the unit is to operate over its correct
range. In calibrating the probe any capacitance associated with the probe
and its leads is cancelled out.
