Introduction 3
1.2 Operating Modes
The 880 has three modes of operation:
Normal Mode
Normal mode is the weighing mode of the indicator. The indicator displays gross or net weights as required,
and annunciators to indicate scale status and the type of weight value displayed.
Setup Mode
Most of the procedures described in this manual require the indicator to be in setup mode, including
configuration and calibration.
To enter setup mode, remove the fillister head screw from the enclosure backplate. Insert a screwdriver or a
simila
r tool into the access hole and press the setup switch once. The indicator display changes to show the
word SCALE.
The 880 also has an Audit Trail that can track changes to configuration and calibration, allowing the setup
switch to be bypassed with Jumper J4 on the CPU board. If Audit Trail is enabled, setup mode can then be
accessed through the user setup mode.
User Setup Mode
User setup mode (accessed by pressing the MENU key) is used to:
View the audit trail
Set the time and date
View or clear the accumulator value
Change setpoint values
View the current tare value
Enter setup mode (if audit trail is enabled)
See Section 1.4.8 for more information about ente
ring user setup mode.
1.3 Front Panel Display
Figure 1-1 shows the 880 front panel keys and the key functions assigned in normal mode.
The numeric display consists of six 14-segment LED digits. If a n
egative number is displayed the first digit is used
to display “-”, reducing the number of available digits to five.
The symbols on the keys in Figure 1-1 (representing up, down, enter, left, right) describe the
key functions
assigned in setup mode. The keys are used to navigate through menus, select digits within numeric values, and
inc
rement/decrement values. See Section 3.1.3 for information about u
sing the front panel keys in setup mode.
