Checkweighing / Process Control Limits (HI OK LO):
User Action
Balance Response
1
Press the RANGE / FUNCTION button.
Display cycles repeatedly through PCS, HI-LO,
and %.
2
Press the MODE button when HI LO appears on
the display.
HI, LO and 0 flash.
3
Press the ZERO button.
HI flashes and zero is displayed.
4
Place weight on the weighing pan which represents
the upper control limit of the acceptable weight
range.
HI flashes and the upper weight limit is displayed.
5
Press the ZERO button.
LO flashes and the upper weight limit is displayed.
6
Remove the upper limit weight and place weight
on the weighing pan which represents the lower
control limit of the acceptable weight range.
LO flashes and the lower weight limit is displayed.
7
Press the ZERO button.
OK and the lower weight limit are displayed.
8
Remove the lower limit weight.
LO appears and zeros are displayed.
The balance is now ready to check weigh samples. The balance displays OK along with the weight of the sample if the sample is
within the acceptable weight range. If the sample is too heavy, HI and the weight are displayed. If the sample is too light, LO
and the weight are displayed.
To exit check weighing, press the MODE button. The balance then returns to normal operation.
Capacity Tracker:
The capacity tracker provides a graphic display of the used and unused portions of the weighing range and is shown in Figure 7.
Each segment represents 10% of the balance's total capacity. As 10% of the balance’s capacity is used the first segment will illu-
minate. As 20% of the balance’s capacity is reached the second segment will light and so on.

Selectable Filters:
All balances are equipped with three user-selectable vibration filters which reduce nervous readings in varying weighing con-
ditions. The balance was delivered to you set in the normal filtering mode (Fil Nor). Low filtering (Fil Lo) can be selected for
faster response and high filtering (Fil HI) can be selected for noisier conditions.
The stability indicator, “OK”, is illuminated when the variance of the readings are below the preset stability parameters as
selected by the user. The stability indicator is useful in determining the stability of the weighing environment. In normal
weighing the OK stability indicator should come on within five seconds after the sample has been placed on the pan and the
windscreen is closed. If the stability indicator does not come on or takes a very long time this indicates it is too noisy of an
environment for that level. Try improving the environment or raise the filter level to enter the selection mode proceed as fol-
lows: To exit the selection mode and return to normal operation, turn the balance off and then back on again at any time.
