10.3. Function of comparing with threshold values (F..-tHr)
This function allows to compare the weighing result with two, previously programmed
values: upper and lower threshold. The comparison result is signalled on the display and
by acoustic signal, as well as with use of control outputs.
If the weighing result is:
- lower than the lower threshold (but higher than balance minimum) – balance does not
signal and activates output threshold I (option)
- between thresholds – the balance signals OK and activates output threshold II (option),
- higher than the upper threshold – the balance signals MAX and activates output zero
(option).
If the option of weighing with threshold signalling is selected, no activities connected
with the balance are required for this function to work. If the option is not selected,
balance operator may activate the function.
Operations sequence during function activation by the operator:
1.
Press key
MENU
.
2.
After displaying
F..-tHr
press
ENTER
.
3.
The display shows in sequence:
F..-0 – function deactivation,
F..-1 – function activation,
F..-2 – checking of previously entered thresholds values.
4.
After displaying
F..-1
press
ENTER
.
5.
The following options are displayed:
SEt-0 – weighing with signalling of thresholds exceeding,
SEt-1 - entering of lower threshold value (not used, when weighing with thresholds
signalling is selected in the computer),
SEt-2 - entering of higher threshold value (as above),
SEt-3 – zero signalization threshold setting.
6.
Using
ENTER
key select option
SEt-1
.
7.
Set the lower threshold value on the display, using the numeric keys and pressing
ENTER
in the end.
8.
Using
ENTER
key select option
SEt-2
and enter the upper threshold value (as above).
9.
Using
ENTER
key select option
SEt-0
. It activates balance operation with
simultaneous signalling of thresholds exceeding.
10.
To finish the function operation press
F
key, then select
F..-tHr
and
F..-0
.
Checking of entered threshold values:
1.
Press key
MENU
.
2.
After displaying
F..-tHr
press
ENTER
.
The display shows in sequence: F..-0, F..-1 and F..-2.
