DESCRIPTION ScoutII balances are precision weighing instruments, designed to provide years of service. Features include front panel controls, simplified menu, automatic shutoff, multiple weighing units, parts counting and a weigh below hook. A total of ten models are available with full capacity ranges of 200g to 6000g. Five of the models are available with RS232 communications for operation with external computers or printers. The balance can be operated by a 9 Volt battery or with the AC Adapter supplied.
INSTALLATION For best performance, the balance should be used in a clean, stable environment. Do not use the balance in environments with excessive drafts, near magnetic fields or equipment that generates magnetic fields, rapid temperature changes, vibrations or corrosive vapors. Power Connect the AC Adapter at the rear of the balance. For portable operation, install a 9 V battery in the battery compartment as shown in the illustration.
INSTALLATION (Cont.) Weigh Below Hook For below balance weighing applications (eg. density determination), the weigh below hook may be installed at the bottom of the balance as shown. Do not over tighten the screw, tighten finger tight. Place the balance on a suitable stand which will allow below balance weighing.

MENU DESCRIPTION The User Menu permits you to activate the Auto Shut-off feature, select weighing units, select parts counting, select printing parameters on RS232 equipped models and perform Linearity calibration and store settings. Bolded items shown in the menu are factory default settings. Each menu item is covered in a separate procedure in this manual, to enter an individual menu item and select it requires alternating between the Mode Off and Zero On buttons.
SPAN CALIBRATION ScoutII balances are calibrated before shipment, however calibration can be affected by changes in location, temperature, or rough handling. Check the balance with the calibration mass supplied. If calibration is required, proceed as follows: NOTE: NOTE: 1200g and 6000g 1200g, 4000g and 6000gbalances balancesare arenot not supplied supplied with masses. masses 1. With the balance ON, press and hold Zero On until CAL is displayed then release it.
ACTIVATING UNITS 1. Start with the balance OFF. Press Zero On until MENU is displayed. 2. Press Mode OFF until UnitS is displayed. 3. With UnitS displayed, press Zero On to display the grams indicator "g" with its current setting or On g or OFF g. 4. To change the displayed setting, press Mode Off. 5. To accept the displayed setting, press Zero On. The display will advance to the next weighing unit. 6. Repeat steps 4 and 5 for each weighing unit and parts counting.
PARTS COUNTING (CONT.) 7. To read the weight of the parts, press Mode Off to change to any of the activated weighing units. 8. To return to a weighing mode, press Mode Off to select a weighing unit, the display indicates the weight of the container as a negative value. Simply press Zero On to tare the balance. Taring the balance does not affect the sample weight which is stored and retained as long as the balance remains on. 9.
SETTING PRINT MENU FUNCTIONS This procedure permits you to set one or all of the RS232 communication parameters on balances equipped with RS232. Each parameter can be entered and set individually. ENTERING THE PRINT MENU 1. Start with the balance OFF. Press Zero On until MENU is displayed. 2. Press Mode OFF until Print is displayed. 3. With Print displayed, press Zero On until PoWr is displayed.
