• • Remove packing material from the instrument. • Check the instrument for transport damage. Immediately inform your Ohaus dealer if you have complaints or parts are missing. • Store all parts of the packaging. This packaging guarantees the best possible protection for the transport of your... -
Page 9: Selecting The Location
2.2 Selecting the Location The balance should always be used in an environment which is free from excessive air currents, corrosives, vibration, and temperature or humidity extremes. These factors will affect displayed weight readings. DO NOT install the balance: • Next to open windows or doors causing drafts or rapid temperature changes. -
Page 10: Connecting Power And Communications
Communication Connections When an optional printer or computer is going to be used with the balance, connect an Ohaus RS232 Interface Cable to the connector at the rear of the balance and the external device. Refer to paragraph 5.7 Accessories for Bottom View of Balance cable information and part numbers. -

Page 13: Calibration Masses
3.3 Calibration (Cont.) Calibration Menu Protection NOTES: • Calibration may be locked out to prevent unauthorized personnel from changing calibration. If calibration has been locked out, you can only access Cal Test. • To lock out calibration menu, after calibration, refer to the section titled Menu Lock-Out Protection, paragraph 4.12. -
Page 14: Internal Calibration
3.3.1 Internal Calibration (InCAL On Navigator balances equipped with the InCal feature, calibration can be accomplished using the internal calibra- tion mass. InCal requires use of the AC adapter supplied with the balance. When the balance requires calibration, a screen prompt of CAL NOW appears. This display can be turned off as described under Calibration Message. Also, a software feature is incorporated which permits the internal calibration mass to be adjusted by +100 divisions. -

Page 17: Span Calibration
3.3.4 Span Calibration Span calibration utilizes two calibration points, one at zero and a choice of either half capacity or full capacity. All balances will prompt for a particular weight which is shown in the table. If the prompt calls for a half capacity mass, you can use a full capacity mass, the balance will accept it. -
Page 18: User Calibration
3.3.5 User Calibration User calibration is used when it is desired to calibrate the balance using a mass of known value. User calibration limits are no less than the 1/2 nominal capacity point and no more than the display over limit. For example, on a 210g balance, it's no less than 100.00g and no more than 210.09g. -
Page 19: Linearity Calibration
3.3.6 Linearity Calibration Linearity calibration utilizes three calibration points, one at zero, center span and full span. This method minimizes deviation between actual and displayed weights within the balance's weighing range. Sample display illustrates a 210g balance. Procedure • Clear the pan. •... -
Page 20: Calibration Test
3.3.7 Calibration Test Calibration test feature allows a check of a known calibration mass against the last stored calibration information in the balance. Sample display illustrates a 210g balance. Procedure • Clear the pan. • Press the Setup button, CAL is displayed. •... -

3.4 Weighing Navigator balances are shipped with grams only enabled. When the balance is to be used with other units of mea- sure, the desired unit must be enabled. Refer to paragraph 4.8 to enable other measuring units. 32g models are shipped ready to weigh in g, oz t, dwt and ct. -
Page 23: Percent Weighing
3.5 Percent Weighing Percent Weighing is enabled only when Percent is turned ON in the Mode menu under Setup. Percent weighing permits you to place a reference load on the balance, then view other loads as a percentage of the reference. The load you place on the pan as a reference may be displayed as any percentage you select from 5% to 100% (in 1% incre- ments). -
Page 24: Parts Counting
3.6 Parts Counting Parts Counting is enabled only when Count is turned ON in the Mode menu under Setup. In the parts counting mode, the balance displays the quantity of parts you place on the pan. Since the balance determines the quantity based on the average weight of a single part, all parts must be reasonably uniform in weight. -
