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 7.0 on page 67).
Press the CLEAR key twice to clear the accumulator.
1.3 Softkey Operations
Softkeys can be defined to provide additional operator
functions for specific applications. Softkey assignments
are listed on the tabs shown at the bottom of the LCD
display; softkey functions are activated by pressing the
arrow keys below the softkey tabs (Figure 1-1 on
page 3). The particular set of softkeys shown on the
display is determined by the indicator configuration and
program. Enabling softkeys is done through the
FEATURE menu (see Figure 3-13 on page 44)
