1.1 INTRODUCTION This service manual contains the information needed to perform routine maintenance and service on the Ohaus Scout Electronic Balances, 200g, 400g and 600g capacities. The contents of this manual is contained in five chapters and are listed as follows: Chapter 1 Introduction - Contains information regarding service facilities, tools and test equipment, measuring masses, and specifications. Solder (rosin core). 1.4 TEST MASSES REQUIRED The masses required to test the Scout Electronic Balances must meet or exceed the requirements of ASTM Class 4 Tolerance. The mass values are listed in Table 1-1.
CHAPTER 1 INTRODUCTION 1.5 SPECIFICATIONS Complete specifications for the Scout Electronic Balances are listed in Table 1-2. When a balance has been serviced, it must meet the specifications listed in the table.
Before servicing the balance, determine what specifications are not met. CHAPTER 1 INTRODUCTION. CHAPTER 2 THEORY OF OPERATION 2.1 BALANCE OPERATION This chapter contains basic theory of operation of the balance. An exploded view drawing is included in Chapter 5 which identifies all mechanical components of the balance. 2.1.1 Operation The AC Power Adapter cord plugs into a receptacle at the rear of the balance.
The Rezero On switch when pressed (located on the PC Board), applies power to the balance. Figure 5-2, for mechanical components, refer to Figures 2-2 and 5-1. Two types of Transducers are used in the Scout balances, one type utilizes four Strain Gauges in a full bridge configuration, the second type contains two Strain Gauges in a half bridge configuration. CHAPTER 2 THEORY OF OPERATION PRINTED CIRCUIT BOARD DESCRIPTION ( See Block Diagram Figure 2-3 and Schematic Diagram, Figure 5-2) 2.3.1 Power Supply Power is supplied to the unit from either an AC Adapter which provides 9 volts dc or an internal 9 volt Alkaline battery.
CHAPTER 2 THEORY OF OPERATION 2.3.3 Low Voltage Detector The purpose of the Low Voltage Detector circuitry is to inform an operator when the battery voltage drops to level which would cause improper operation of the balance and require replacement of the battery. Transistors Q4 and Q7 form the low voltage detector. CHAPTER 2 THEORY OF OPERATION 2.3.5 Full Bridge Weight A/D Converter (Cont.) Instead of comparing the sawtooth against a reference signal, this circuit compares it against a ramp signal generated by transistor Q2, resistors R2, R3 and capacitor C12. At time zero, capacitor C12 starts to charge through resistors R2 and R3. The output of the ramp circuit starts high and goes low.

CHAPTER 3 TROUBLESHOOTING 3.3 ERROR CODES Scout balances are equipped with software which will display an error condition when it occurs. Table 3-2 Error Codes, describes the various error codes which can appear on the display and specifies the probable reason and remedy. CHAPTER 4 MAINTENANCE PROCEDURES 4.1 PREVENTIVE MAINTENANCE Ohaus Scout balances are precision instruments and should be handled as follows:.
Store in a clean dry area which is dust free. Use a cover if possible. Keep clean at all times. CHAPTER 4 MAINTENANCE PROCEDURES 4.1.1 Preventive Maintenance Checklist (Cont.) 3.
Clean the outside of the balance using a damp cloth with water. CAUTION DO NOT USE CHEMICAL CLEANERS OR SOLVENTS OF ANY TYPE. SOME CLEAN- ERS ARE ABRASIVE AND MAY AFFECT THE FINISH OF THE BALANCE. Span Calibration. A 300 g calibration mass is supplied with the 600g balance. Linearity calibration requires an additional 100g mass for 200g Balances, 200g mass for 400g balances and 300g mass for 600g balances.
Masses are available from Ohaus as accessories. CHAPTER 4 MAINTENANCE PROCEDURES 4.2.2.2 Calibration Procedure (Cont.) Span and Linearity Scout balances are calibrated before shipment, however, calibration can be affected by changes in location, temperature, or rough handling. The balance should be warmed up for at least 5 minutes. CHAPTER 4 MAINTENANCE PROCEDURES 4.2.2.2 Calibration Procedure (Cont.) Activating Units and Parts Counting Activating Units and Parts Counting Activating Units and Parts Counting Activating Units and Parts Counting Activating Units and Parts Counting 1. When the balance displays, press Rezero On to display the grams indicator 'g'.
CHAPTER 4 MAINTENANCE PROCEDURES 4.2.3 Performance Tests Accurate performance of a Scout balance is determined by a series of three perfor- mance tests. The displayed readings are compared with the tolerances listed in Table 4-2. Tolerance values are expressed in counts. A one count change is equal to the last digit shown on the balance display.
CHAPTER 4 MAINTENANCE PROCEDURES 4.2.3.1 Precision Test (Cont.) Adjustment If the deviation for any set of readings (using the same mass placed on the center of the Pan) is greater than +1 count, the balance does not meet the Precision Test specification. CHAPTER 4 MAINTENANCE PROCEDURES 4.2.3.3 Centered Load Test (Cont.) Test 1. Place a mass equal to the maximum capacity of the balance on the center of the Pan (6) and note the reading. If the displayed weight is greater than 1 count higher or lower than the value of the applied mass, proceed to paragraph 4.2.2.2 and calibrate the balance.

WHEN the Supreme Court decided on June 28 that the Boy Scouts could bar gay members, it agreed that opposition to homosexuality was part of the organization's 'expressive message.' ' This message, the argument went, was right there in the Scout Oath and Law, the guiding principles that generations of boys have had to know by heart and regularly recite, raising their arms in that familiar three-fingered salute and promising to be (among many other things) 'clean' and 'morally straight.' ' The dissenting justices in the 5-to-4 ruling were perplexed.
'It is plain as the light of day that neither one of these principles, 'morally straight' and 'clean,' says the slightest thing about homosexuality,' Justice John Paul Stevens wrote. 'Indeed, neither term in the Boy Scouts' law and oath expresses any position whatsoever on sexual matters.' ' Anyone looking for an explicit condemnation of homosexuality by the Boy Scouts has little to go on. The statement posted on the Boy Scouts' Web site after their court victory was a model of tactful restraint: 'We believe an avowed homosexual is not a role model for the values espoused in the Scout Oath and Law. Boy Scouting makes no effort to discover the sexual orientation of any person. Scouting's message is compromised when prospective leaders present themselves as role models inconsistent with Boy Scouting's understanding of the Scout Oath and Law.' ' For slightly more stem-winding, plain-spoken views on scouting's mission and message - and on moral issues, sexual and otherwise - the justices might have turned to the first Boy Scout manual, published in 1910 by Ernest Thompson Seton, a founding father of the Boy Scouts.
Seton, an author and self-styled naturalist, created the Woodcraft Indians, a precursor of the Boy Scouts, and became the country's first chief scout. Why scouting? Degeneracy is the word. To combat the system that has turned such a large proportion of our robust, manly, self-reliant boyhood into a lot of flat-chested cigarette smokers, with shaky nerves and doubtful vitality, I began the Woodcraft movement in America. Without saying as much, it aimed to counteract the evils attendant on arena baseball, football, and racing, by substituting the better, cleaner, saner pursuits of Woodcraft and Scouting. Getting together with the guys and some brews to watch the game? Not very manly, in Seton's view.
Wolf Scouts Manual
The personal interest in athletics has been largely superseded by an interest in spectacular games, which, unfortunately, tend to divide the nation into two groups - the few overworked champions in the arena, and the great crowd, content to do nothing but sit on the benches and look on, while indulging their tastes for tobacco and alcohol. Not that male bonding is a bad thing: What is a camp without a camp-fire? - no camp at all, but a chilly place in a landscape where some people happen to have some things. Not in the steam radiator can we find the spell; not in the water coil; not even in the gas-log: they do not reach the heart. Only the ancient sacred fire of wood has power to touch and thrill the chords of primitive remembrance. When men sit together at the campfire, they seem to shed all modern form and poise, and hark back to the primitive - to meet as man and man - to show the naked soul.

Your camp-fire partner wins your love, or hate, mostly your love; and having camped in peace together, is a lasting bond of union, however wide your worlds may be apart. The campfire, then, is the focal center of all primitive brotherhood. We shall not fail to use its magic powers.
The primitive state comes naturally to youngsters: The boy from 10 to 15, like the savage, is purely physical in his ideals. I do not know that I ever met a boy that would not rather be John L. Sullivan than Darwin or Tolstoy. Therefore, I accept the fact, and seek to keep in view an ideal that is physical, but also clean, manly, heroic, already familiar, and leading with certainty to higher things.
Advertisement Higher things, yes, but there should be time for fun: The clubroom must not be made cosey like a lady's boudoir, as the boys must be able to romp in it occasionally, or play handball, or 'Bang the bear,' etc. So you want furniture that will pack away into a corner, such as folding wooden chairs, small tables and a cupboard in which to put away books, games, etc., when the romp comes on. Seton counsels absolute frankness on sexual issues, but when it comes to giving details, he delegates: In this handbook I have touched upon many important items of a boy's education, but there is scarcely one more important than that of continence. The prudish mystery with which we have come to veil this important question among the youth of both sexes is doing incalculable harm. The very secrecy with which we withhold all knowledge from the boy prompts him the more to take his own line equally secretly, and, therefore, injuriously.
I have never known a boy who was not the better for having the matter put to him frankly and fully. For an instructor to let his boys walk on this exceedingly thin ice without giving them a warning word, owing to some prudish sentimentality, would be little short of a crime.
Everyone should read 'From Youth Into Manhood,' by Winfield S. Hall, M.D.; sexual hygiene for young men and older boys. Hall's book, which was intended for Y.M.C.A.
