weight may be added to assure the calibration of the
system. The zero determined during the previous
calibration is not affected.
For example, with a tank containing an unknown amount
of material (remote scale):
a) Access the calibration mode, ie:
From the Weigh Mode by pressing:
1 0 0 <SELECT> 2 3 6 4 0 <ID>
<ENTER>
Note: Accessing the calibration mode with a remote
keyboard:
100 <SELECT>
54321 <ID> <ENTER>
b) Toggle to the “Temp Zero?” routine with the
<SELECT> key.
c) At the "Temp Zero?" prompt press:
<ENTER>
The displayed value is zeroed out.
d) Apply the calibration weight to the tank.
e) Key in the value of the calibration weight:
1000<ENTER>
f) The numeric display should show the
entered value.
g) Remove the calibration weight from the tank.
The display should return to zero. If the
display reads as specified, at the "Cal OK?"
prompt press:
<ENTER>
Otherwise, to repeat the calibration process, press
<CLR>
and then repeat steps (b) through (g).
h) To save the newly determined calibration
weight, at the "Enter = Save" prompt, press:
<ENTER>
i) Then to return to the weighing modes, at the
"ENTER = EXIT" prompt, press:
<ENTER>
and the 574 will return to the weigh mode.
d) "Only Zero?"
(Calibration Re-zeroing:)
If it is desired to only re-establish the calibration zero of
the 574 without affecting the established gain, this may
be done during the calibration process by pressing the
<ENTER> key at the "Only Zero?" prompt. After doing
so, the display will flash the calibration units message
and then "Adj Zero!" for one second. Then the display
will advance to the "Cal OK?" prompt.
This may be useful in tank weighing applications where
the re-zero parameter (P118) is set very low in order to
prevent inadvertent re-zeroing. A build-up of sludge
may be zeroed out in this manner.
For example, with the connected scale platform cleared
of any extra weight:
a) Access the calibration mode, ie:
From the Weigh Mode by pressing:
1 0 0 <SELECT> 2 3 6 4 0 <ID>
<ENTER>
Note: Accessing the calibration mode with a remote
keyboard:
100 <SELECT>
54321 <ID> <ENTER>
b) Toggle to the “Only Zero?” routine with the
<SELECT> key.
c) At the "Only Zero?" prompt press:
<ENTER>
The displayed value is zeroed out.
The display will briefly flash: "Adj Zero!" and then:
"CAL OK?"
Press <ENTER> to accept the newly established zero or
<CLR> to re-do the calibration. Following the
