Front Panel Controls:
Figure 4 Balance Front Panel
Note: The annunciators CNV,
σ
and X are shown in Figure 4, but are not available through any front panel controls.
However, these functions along with all other front panel functions are available through RS-232 commands. These
commands are discussed later in the RS-232 section of the manual.
The ON/OFF (I/O) Button:
The ON/OFF button is located in the upper left corner of the balance’s front panel. When the balance is off, pressing the button will
start the turn on sequence shown in Figure 3. During this sequence the balance is doing an automatic systems checkout to insure it is
functioning properly.
When the balance is on, pressing the ON/OFF button will turn off the display.
The RANGE/FUNCTION Button:
Single Range Balance Models:
Pressing the RANGE/FUNCTION button begins the following menus cycle:
• PCS – Front panel parts counting
• HI OK LO – Checkweighing
• CAL 1 – Autocalibration
• CAL 2 – Linearity
•
T – Live animal weighing
• % - percent weighing
To select the desired function, press the MODE switch when it appears on the display.
Note: Front panel parts counting is not available with bi-directional RS-232 enabled.
Dual Range Balance Models:
Pressing the RANGE/FUNCTION button allows you to choose from low (LO), high (HI) and autorange (HI LO). As a range is
selected its annunciator briefly appears at the upper right of the display. Autorange automatically switches from low range to high
range when a weighing exceeds the capacity of the low range.
Note: On dual range balance models, pressing the RANGE/FUNCTION and MODE buttons simultaneously will duplicate
the menu shown above for single range balances.
The ZERO Buttons:
There are two (2) ZERO buttons. Pressing either button at any time returns the display to zeros. When a weighing that has been
zeroed out is removed from the weighing pan, a negative reading is displayed. To return the display to zeros, press one of the ZERO
buttons.
