Version 2.4 Page 25
The weight tared is deducted from the allowable range of the scale, reducing the maximum
weight that can be displayed.
The tare adjustment is stored when power is removed and is re-used when next powered up.
The [TARE] key can operate in all modes (i.e. Industrial, OIML and NTEP). Refer to Chapter 6:
Approvals on page 45 for more information on modes.
GROSS/NET Key
This key toggles the weight display between the Gross weight and the Net weight if a Tare
weight has previously been acquired using the [TARE] key.
GSE-LINK Activation
This feature is used to temporarily connect a PC to the Model 250 for calibration and setup
purposes.
A long press of the [GROSS/NET] key from the weigh mode will toggle the GSE-LINK infrared
communications On/Off.
When the GSE-LINK has been enabled the following will occur:
• The indicator briefly displays the prompt opto-L.
• The editing annunciators (i.e. GRP, ITM, etc.) will flash for up to five minutes while the
indicator searches for activity. During this time period, the Model 250 also disables the RS-
232 communications.
If the indicator is successful in locating activity, the editing annunciators will continue to flash
during the entire period of communications.
If the indicator fails to locate activity, the GSE-LINK will be disabled and the editing annunciators
will stop flashing. The Model 250 will also revert back to the normal RS-232 communications (i.e.
the SERIAL:TYPE setting will be re-activated).
PRINT Key
If a printer or computer has been attached to the Model 250 and the manual print function
has been selected, the [PRINT] key will trigger an output of the current weight reading.
The PRINT prompt is displayed while waiting for the printer to accept data. If the printer is
offline the PRINT prompt will remain for a maximum of 10 seconds before the operation is
cancelled. Each weight printed is automatically added to an internal total weight.
A long press of the [PRINT] key will print the accumulated total. The total weight is then cleared
automatically.
FUNCTION Key
When leaving the factory, the [ f ] key has no function programmed. The primary
function of this key can be selected from a number of different choices including peak-
hold, counting, etc. Refer to page 37 for details of the available functions. Each primary
function has an associated overlay sticker that should be applied underneath the [ f ] key to label
the function of the key.
A long press of the [ f ] key may be used for certain functions depending on the primary function
of the key.
