Enclosures
The
820i
is available in universal (tilt-stand) and panel
mount enclosures. Stainless steel enclosures are rated
for NEMA 4X/IP66. This manual provides assembly
drawings and replacement parts lists for the universal
model; supplemental documentation provides
information specific to the panel mount model
(Section 1.4 on page 4).
1.1 Operating Modes
The
820i
has two modes of operation:
Normal mode
Normal mode is the weighing mode of the indicator.
The indicator displays gross, net, or tare weights as
required, using the secondary display to indicate scale
status and the type of weight value displayed. Once
configuration is complete and a legal seal is affixed to
the large fillister-head screw on the indicator
enclosure, this is the only mode in which the 820i can
operate.
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 large fillister head
screw from the enclosure. Insert a screwdriver or a
similar tool into the access hole and press the setup
switch once. The indicator display changes to show
scale configuration menus.
1.2 Indicator Operations
Basic
820i
operations are summarized below:
Toggle Gross/Net Mode
Press the
GROSS/NET
key to switch the display mode
from gross to net, or from net to gross. If a tare value
has been entered or acquired, the net value is the gross
weight minus the tare. If no tare has been entered or
acquired, the display remains in gross mode.
Gross mode is indicated by the word
Gross
(or
Brutto
in
OIML mode); net mode is indicated by the word
Net
.
To display audit trail information, press and hold the
Gross/Net
mode key for three seconds. Weighing
functions continue while audit trail information is
displayed. Press the
Gross/Net
or
CLR
key to exit the
audit trail display.
Toggle Units
Press the
UNITS
key to switch between primary,
secondary, and tertiary units.
Zero Scale

and wait for the standstill annunciator ( ).
2. Press the
ZERO
key. The center of zero ( )
annunciator lights to indicate the scale is zeroed.
Acquire Tare
1. Place container on scale and wait for the
standstill annunciator ( ).
2. Press the
TARE
key to acquire the tare weight of
the container.
3. Display shifts to net weight and shows the word

on the display.
Remove Stored Tare Value
1. Remove all weight from the scale and wait for
the standstill annunciator ( ).
2. Press the
TARE
key (or, in OIML mode, the

Print Ticket
1. Wait for the standstill annunciator ( ).
2. Press the

Accumulator Functions
The accumulator must be enabled before use in either
normal mode or setpoint operations. Once enabled,
weight (net weight if a tare is in the system) is
accumulated whenever a print operation is performed
using the
PRINT
key, digital input, or serial command.
The scale must return to zero (net zero if a tare is in
the system) before the next accumulation.
The
Display Accum
softkey can be configured to
display the current accumulator value. Printing while
the accumulator is displayed, or when the setpoint
PSHACCUM function is active, uses the ACCFMT
print format (see Section 6.0 on page 54).
Press the
CLEAR
key twice to clear the accumulator.
