33.1 European Specific Modifications
OIML => Organization for International Legal
Metrology
OIML Parameter:
An OIML selection parameter, P410, has been created.
To prevent accidental switching of this parameter once
the parameter is selected, it may only be changed by
entering <9991> <ENTER> to enable OIML or <9990>
<ENTER> to disable OIML. It cannot be changed by
simply pressing <ENTER> alone. When a DEFAULT
SETUP (P65001 or 65002) is performed the current state
of the OIML selection is NOT affected. This is similar
to the operation of the model number parameter.
Enabling the OIML parameter has the following effects:
a. The layout of the keys used on the OIML
version of the keypad is assumed. Refer to
figures 51 and 52 for a picture of the keypad.
Note that the units key has been eliminated since it is not
normally required in Europe. However it can easily be
implemented by programming Macro 15 to perform a %
u.
The OIML keypad will be included in the 550 version
with CE labeling, part number 200550-03000. The
keypad is also available separately as GSE part number
44-35-29xxx.
Please note that the inverted 'T' configuration of the keys
for scrolling in ASCII characters has been preserved.
For example, the middle key in the top row is still the up
arrow key even though it is now the print key. (The print
key is a down arrow key with the standard keypad and
OIML disabled.)
The only complication that arises from this is that the
<SELECT> key now is the right arrow key. Therefore
the operation is somewhat context sensitive. When the
F3 key is pressed during an entry, if the preceding entry
is purely numeric, the F3 key performs the <SELECT>
function and the indicator proceeds to the specified mode
or parameter. However if the preceding entry contains
any non-numeric characters, then the F3 key performs a
right arrow function, appending an 'A' to the end of the
entry. The F3 key without an entry always performs the
<SELECT> function.
However, in certain setup modes the right arrow key was
used to scroll through the existing entry. Specifically,
macros (P800 - P816), input interpreter strings (P911,
921, etc...) and macro debug (P64200) used the right
arrow key to scroll to the next character within these
selections while the <SELECT> key would advance to
the next parameter.
Therefore, these modes will use the [->T<-] (tare) key to
scroll to the next character within these parameters.
Also, within the macros, the <PRINT> previously
allowed the printing of selected the macro. Since the []-
> ([PRINT]) key is now the up arrow key and that key is
used to begin alpha entries, it is necessary to press the
<F2> key to print a specific macro.
b. The overload indication of the indicator,
"Code-03 Over-load" and "Code-02 Under-
Load", will occur at nine divisions (as defined
by P111) above/below capacity (per P110). The
overload is still based upon the zero established
during calibration of the indicator to the
platform. Therefore subsequent use of the front
panel zero key will shift the maximum
displayed value upward or downward,
depending on the amount zeroed out.
c. The name of certain parameters will include an
indication of whether the values of those
parameters were determined by the indicator or
by some other means such as operator entry or
memory recall (ie preset). These parameters
table 49.
The names in table 49 will be preceded by a "P" if the
value is preset, ie not determined by the indicator, when
the name is printed or shown on the display. This preset
marking ability also applies to the user supplied names
which are now possible for all parameters. Refer to the
namable weight parameters section for more
information.
The tare parameter will be considered not preset
when an
auto-tare is performed or when it is cleared (by pressing
<0> <TARE>) or if it is lost after a power-down (if
P161 TrSav = Disbl). When the tare is changed in any
other manner (ie entering a numeric tare, a value
received via serial transmission, recalled from a
database, copied from another parameter with the %C
command, etc...) then the tare will be considered preset.
