ENTER Touch pad
The Enter pad is used for the transfer
of numerical data to the corresponding
operating parameters and for the initia-
tion of various operations, such as
zeroing and spanning.
The first time the Enter pad is activated
after selecting one of the Function se-
quences, the analyzer will ask for a
password code as shown below. This is
to prevent tampering with the settings
by unauthorized personnel. The pass-
word code is entered using the Input
Control pads. If an incorrect password
is entered, the CODE display will re-
main and the entry displayed will be re-
set to the value of “0.”
When the correct password has been
entered, the Enter pad will sequence
through the various entry modes as
shown in Figure 4-2 and as described
in the following sections.
The
password
has been set to the
value
“1”
at the
factory
.
We would recommend to change the
password immediately after start-up for
safety reasons.
Please use a password with two digits.

INPUT-CONTROL Touch pads
The Input-Control pads are used for the
adjustment of the individual entry pa-
rameter values. Momentary activation
of either pad will increase or decrease
the values by 1.
UP
∆
increases the current value by 1
DOWN
∇
decreases the current value
by 1
If either pad is activated and held, the
value will change continuously with the
rate or change accelerating. When the
minimal value is reached, the rate of
change will slow in order to facilitate
entry of the minimal value.
Each of the entry parameters is as-
signed an acceptable tolerance range
which limits the range of values when
entering parameters. In addition, all en-
tries are subjected to a plausibility
check as added protections against
possible entry error.
