Accumulation Operation

The Accumulation function is always on and allows basic statistical information to be collected from multiple weighings.
Accumulated data collected includes total count (or number of samples), total sample weight, average sample weight, and a
standard deviation of sample weight. The information continues to accumulate and is retained until cleared or the scale is
turned off.
To add a weight value to the Accumulation memory, place the item on the platform, then short
press the NEXT +/- button. M-ADD is momentarily flashed on the display to indicate that the
value is added into memory. Repeat this step for each additional item.
To view the Accumulation data, long press the NEXT +/- - - - - button. Accumulation data is displayed
momentarily in the following sequence:
Display parameter COUNT, then the total number of weighed samples (example 150).
Display parameter TOTAL, then the total accumulated weight value (example 1504.05 kg).
Display parameter AVG, then the calculated average of the accumulated values (example
10.03 kg).
Display parameter S-DEV (standard deviation), then the calculated standard deviation
(example 4.502 kg).
Display END, then the display returns to the active weighing mode.
To clear the Accumulation memory, press the C button during the display sequence. At the end
of the display sequence, CLEAR is displayed and returns to active weighing mode.
Notes: 1. If a value exceeds the size of the 6 digit display, the number will first be displayed in
reduced decimal places, after this, the g and lb:oz units may be changed to kg and lb
units. If the value still exceeds the display digits, Err will be displayed. The correct
value with the original weighing unit will always be printed when the Accumulation
data is printed.
2. I/O- External Input setting should NOT be set to: S-S or T-S-S (refer to Section 3.6.6),
since this menu setting also controls the functionality of the NEXT +/- button. The
accumulate function is not available if either of these I/O selections are made.
