AD-4407A Weighing Indicator
11. Hold Function
This function displays the hold weight data after averaging the weight data for
a specific period.
Useful to determine a living animal’s weight.
Averaging time can be set up to 9.9 seconds by a 0.1 second step.
3 methods are available to start averaging; manual start, start automatically
after stable and manual / automatic start.
Manual start is available with key switch or external input.
Serial interface commands are also available; averaging start, releasing the hold
data and outputting the hold state. Refer to “13.3.4. Commands for Hold Function”.
Caution This function can not be used with
Cf00
=
1
.
Averaging can not start at a displayed value smaller than +/- 5 digits.
OVER data is not included for averaging.
When powered off, hold is released automatically.
No peak hold function.
The Display and the Data Output of Hold and Average
The weight display blinks during the averaging period.
The output data in the averaging period is the actual weight at the time.
The weighing unit blinks when the weight display is in the hold state.
The output data format of the hold weight data is the same as that of the
normal weight data except the header of stable state is “HD” in the response
to the “RW” or “RW,n”(n=1 or 2) command.
Relations to the Other Functions
If automatic accumulation (
f20
=
21
) and/or auto print (
f37
=
2
,
3
,
f40
=
2
,
3
) is set,
accumulation and/or data output is performed after the hold data is obtained.
11.1. Setting the Hold Functions
f27
determines how to start averaging.
f27
=
1
Manual start: Start averaging and release with key switch
operation.
f27
=
2
Automatic start: After passing the inhibit region * and detecting
stable **, start averaging automatically, release when the weight
returns to the inhibit region.
f27
=
3
Both Manual start and Automatic start.
*inhibit region 0 +/- 5 digits
**stable detection Satisfied both
