PTT MODE
The "P.t.t.", press-to-tolerance mode, is used when the actual tolerance weight is to
be used. Simply place the over or under tolerance weight on the scale, recall the
current over or under tolerance by pressing OVER or UNDER, then press and hold
OVER or UNDER to enter the new value into memory. A verification message, "Ent
Pr," will be displayed to indicate that the new
tolerance value has been
accepted. Double check that the new value has been entered by recalling the over
or under value momentarily.
To recall an over or under value without changing it, press the OVER or UNDER
button to display the value, and when done, press the OVER or UNDER button
again momentarily to return to the normal weighing mode. If the button is pressed
and held, this will cause a new value to be entered, so only press the button
momentarily to avoid entering a new value.
DIS MODE
In the disable mode, the over or under tolerance can only be recalled, not altered, as
a security feature to prevent tampering.
Recall by pressing OVER or UNDER. The over or under tolerance will be displayed
only as long as the button is held down. After release, the scale returns to the weigh
mode.
CONVERT
When the Convert function is enabled via the menu item "Push Button Enable (P.b.)"
parameter, each time the CONV button is pressed the weight display will change from lb to
kg to oz to lb & oz. You may select 2-way, 3-way or 4-way convert from the menu
parameter" Convert Operation Select (CSL)".
All 4 weight display units are available in the "Standard" mode. In either "HB44" or "CAn"
legal-for-trade modes, the lb & oz weight display is disabled. This is due to the fact that
neither NIST nor Canadian Weights and Measures accept lb & oz as a legal-for-trade
display at this time. Convert may be disabled to prevent inadvertent operator error.
PRINT FUNCTION
When the Print function is enabled via the menu parameter "Push Button Enable (P.b.)",
each time the PRINT button is pressed, a data transmission is initiated. The weight data is
transmitted only when the scale is not in motion and not in overrange. Refer to Section 8
for details on the 4200 Data Interface.
