49 520 Indicator Installation Manual
8.0 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 and
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.
Peak hold function is selected using the PK HOLD
parameter on the PROGRM menu (see Section 3.2.5 on
page 30).
Normal Setting
• Positive Peak
• Manual Reset
This is the basic peak hold function in which a
weight is applied to a scale and the greatest net
weight value is held in memory until the weight
is removed from the scale, and either the ZERO
or
PRINT
key is pressed. If the display is in gross
mode, the peak net weight can be displayed by
scrolling to the net mode with the GROSS/NET
key.
Note
A tare weight can be used with peak hold. At
the tare value, the highest peak hold is 0 net.
Tare is cleared by returning to gross zero and
pressing the TARE key.
Bi-Dir Setting
• Bi-Directional Peak
• Manual Reset
This is the same as NORMAL parameter setting,
except that the peak can either be a positive or
negative number, determined by the absolute
weight value. This means that if a positive peak
is displayed, a negative weight value of greater
absolute value can update the peak information
in the same cycle. As above, the peak cycle is
reset by pressing the ZERO or
PRINT
key after
the weight has been removed.
Auto Setting
• Positive Peak
• Auto Print
• Auto Reset
This is the same as NORMAL parameter setting,
except that automatic print occurs when the
scale load is reduced to 0 ± 10 display divisions
and the scale achieves standstill. Following the
print command, the peak value is cleared and
reset automatically. Press the
ZERO
or
PRINT
key
to clear the peak hold value.
Use the
GROSS/NET mode key to display gross
weight data during peak hold function cycles.
