5 520 Indicator Installation Manual
1.3.14 Display Accumulator
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.
1. Press and hold the
G/N
key for three seconds to
display the accumulated value if accumulator
is enabled.
2. Press the
UP
key to clear the accumulator or
the
PRINT
key to print the accumulator.
Note
The PRINT key only performs one
accumulation. Weight must return to zero
before another accumulation is allowed.
1.3.15 Count Display Mode
Count mode is entered by pressing the
MODE
(
GROSS/
NET
) key from normal weighing mode when count
mode is enabled. In count display mode, the display
shows the number of parts rather than weight. The
annunciator at the right side of the LCD display reads
piece count (PC). Pressing the
PRINT
key sends the
CFMT print format data string to the serial port.
If a sample weight has not yet been acquired, the
indicator switches automatically to sample acquisition
mode (see Section 6.0 on page 46).
1.3.16 Peak Hold Mode
The peak hold function is used to determine, display,
and print the greatest net weight read during a
weighing cycle.
A weighing cycle ends when the print command is
given, or when the peak net weight is manually cleared
by the
ZERO
or
PRINT
key. Peak hold tracks only net
weight and operates independently of the display. For
example, if the indicator is displaying gross weight, but
AUTO peak hold is active, the display remains in
gross, but the net peak weight is automatically printed
when standstill is achieved at net zero.
Note
Setpoint, time and date, and checkweigh value
changes from weigh mode (press and hold the
UNITS key), accumulator display (press and
hold the G/N key), keyed tare display (press and
hold the TARE key), and password entry front
panel entry modes timeout after 10 seconds if
there is no activity.
