Stabilization Before initially using the balance, allow time for it to adjust to its new environment. Recommended warm up period is 5 minutes. Calibration Refer to paragraph 3.3 and calibrate the balance before proceeding. 3.3 Calibration Navigator balances offer a choice of five calibration methods: Internal Calibration (InCALTM), Span Calibration, User Calibration, Linearity Calibration, and CalTestTM. • InCal TM Internal calibration (InCALTM) of the balance is accomplished by an internal mass (If option is installed). When CAL NOW is selected and set ON, CAL NOW is displayed when the balance requires calibration. When CAL NOW is set OFF, the message CAL NOW is not displayed. • Span - Span calibration ensures that the balance reads correctly within specifications using two weight values: zero and a weight value at 50% of full capacity and or 100% of the balance’s full capacity. • User - User calibration is a method where the balance can be calibrated using a mass of known value and entering that numeric value into the balance. • Linearity - Linearity calibration minimizes deviation between actual and displayed weights within the balance’s weighing range. Three weight values are used: zero, a weight value at midpoint of the balance's weighing range, and a weight value at or near the balance’s specified capacity. • Cal Test - Calibration test allows the stored calibration data to be tested against the current mass being used for the test. • Lock - Can be set on or off. When set on, Span, User and Linearity calibration are locked out and cannot be used.

Models 410g and 4100g use Class 2. Calibration masses are available as accessories. 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. Calibration Masses Before beginning calibration, make sure masses are available. If you begin calibration and realize calibration masses are not available, exit the menu. The balance will retain previously stored calibration data. Calibration should be performed as necessary to ensure accurate weighing. Masses required to perform the procedures are listed in the adjacent table and are available as accessories. NOTE: Any of the calibration modes can be terminated at any time by pressing either the Mode, Units or Setup buttons.

On NavigatorTM balances equipped with the InCalTM feature, calibration can be accomplished using the internal calibra- tion mass. InCalTM 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. The adjust feature is described under Calibration Adjust. Internal calibration can be performed at any time providing the balance has warmed up to operating temperature. • Press the Setup button, CAL is displayed. • Press Enter button, CAL TYP is displayed. • Press Enter button, CAL TYP InCAL is displayed. • Press Enter button, INCAL is displayed. Procedure NOTE: If a weight is left on the pan, the balance will display CLR PAN (remove the weight from the pan). The balance automatically resumes calibration. The internal mass is positioned several times during calibration and then removed, then after a few seconds, CAL SET is displayed indicating a successful calibra- tion. The display returns to WEIGH mode. IMPORTANT ! DO NOT DISTURB THE BALANCE DURING CALIBRATION. IF THE MESSAGE UNSTBL IS DISPLAYED, THE BALANCE WAS UNABLE TO ACQUIRE STABLE DATA DURING INTER- NAL CALIBRATION. THE BALANCE WILL CONTINUE TO PERFORM INTERNAL CALI- BRATION UNTIL READINGS STABILIZE. THE BALANCE WILL THEN COMPLETE THE IN- TERNAL CALIBRATION FUNCTION. TO EXIT INTERNAL CALIBRATION MODE BEFORE COMPLETION, PRESS ENTER OR SETUP BUTTONS. STABILITY CAN BE AFFECTED BY TEM- PERATURE CHANGES, AIR CURRENTS, VI- BRATION, ETC...

On NavigatorTM balances equipped with the InCalTM feature, a screen prompt of CAL NOW appears when the balance requires calibration. This display can be turned off if it is desired not to have the balance indicate that calibration is required. Turning the display off has no effect on the basic balance operation. Procedure • Press the Setup button, CAL is displayed. • Press Enter button, CAL TYP is displayed. • Press button, CAL NOW is displayed. • Press Enter button, CAL NOW ON or OFF is dis- played. • Press or button and select either ON or OFF. When OFF is selected, the CAL NOW message will not appear in the display. • Press Enter button, SAVED is momentarily displayed, then the display indicates CAL ADJ. NOTE: At this point you may continue with the calibra- tion adjust procedure on the next page or exit. The calibration adjust procedure is only used when it is desired to calibrate the internal calibration mass to a known external mass if a difference exits between the known mass and the InCalTM value. • Press Enter button, LOCK is displayed. • Press or button and select either ON or OFF. • Press Enter button, SAVED is momentarily displayed, then the display indicates EXIT. • Press Enter button, display returns to WEIGH mode.

Balances with InCalTM contain software which allows the internal calibration value to be adjusted by + 100 divisions at full scale capacity using an external mass which is traceable to a certified standard. Procedure • Perform the internal calibration procedure. • Press >O/T< button to zero the balance. • Place a mass equal to the span calibration value of the balance on the pan. Note the reading on the bal- ance and see if the balance indicates the exact weight or indicates a higher or lower reading. If the reading is higher or lower, proceed. • Press the Setup button, CAL is displayed. • Press Enter button, CAL TYP is displayed. • Press button until , CAL ADJ is displayed. • Press Enter button, CAL ADJ 0 should be dis- played (0 is factory setting). NOTE: Balance will retain last CAL ADJ setting. • Press or button until desired number is displayed. • Press Enter button, SAVED is momentarily displayed, then display indicates LOCK. • Press Enter button, LOCK ON or LOCK OFF is displayed. • Press or button and select either LOCK ON or LOCK OFF. • Press Enter button, SAVED is momentarily displayed, then EXIT is displayed. • Press Enter button, display returns to WEIGH mode. Note weight reading and remove mass from pan. • Perform the internal calibration procedure. The value entered as an adjustment is now stored. Place the calibration mass on the pan and check. Repeat pro- cedure if further correction is required. • To return to factory setting, follow procedure above and set CAL ADJ to 0.

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. If the prompt calls for a full capacity mass, you can use a half capacity mass. This versatility allows calibration at other than full capacity. Sample display below illustrates a 210g balance. Procedure • Clear the pan. • Press the Setup button, CAL is displayed. • Press Enter button, CAL TYP is displayed. • Press Enter button to select SPAN calibration, CAL TYP SPAN is displayed. • Press Enter button, BUSY is displayed. NOTE: If a weight is left on the pan, the balance will display CLR PAN (remove the weight from the pan). The balance automatically resumes calibration. • Place the calibration mass on pan. NOTE: The PUT WEIGHT message indicates the calibration mass that is on the pan. • Press Enter button, BUSY is displayed. After a few seconds CAL SET is displayed, the display then returns to WEIGH mode. • Span calibration is completed. • Remove calibration mass from the pan. SPAN CALIBRATION MASSES MODEL 32g 210g 410g MASS 30g 100g, 200g 200g, 400g MODEL 810g 2100g 4100g 8100g MASS 400g, 800g 1kg, 2kg 2kg, 4kg 4kg, 8kg • Display changes to PUT WT 200g. The displayed weight is the value of the mass to be used. See the following table for masses that may be used with the different model balances. Values shown in bold are displayed.

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.

When the balance is connected directly to a printer, displayed data can be output at any time by simply pressing PRINT, or by using the Auto Print feature. Connecting the balance to a computer enables you to operate the balance from the computer, as well as receive data such as displayed weight, weighing mode, stability status, etc. The following sections describe the hardware and soft- ware provided with the balance Hardware On the rear of the balance, the 9-pin male subminiature “D” connector is provided for interfacing to other devices. The pinout and pin connections are shown in the adjacent illustration. The balance will not output any data unless pin 5 (CTS) is held in an ON state (+3 to +15 V dc). Interfaces not utilizing the CTS handshake may tie pin 5 to pin 6 to defeat it. IMPORTANT: An Ohaus RS232 cable is required to operate with this balance. A standard RS232 cable will not work. See Accessories listed in paragraph 5.7. Output Formats Data output can be initiated in one of three ways: 1) By pressing PRINT; 2) Using the Auto Print feature; 3) Sending a print command (“P”) from a computer. The output format is illustrated in the RS232 command table which follows. RS232 Connection 1 N/C 2 Data Out (TXD) 3 Data In (RXD) 4* Tare (External signal) 5 Clear To Send (CTS) 6 Data Terminal Ready (DTR) 7 Ground 8 Request To Send (RTS) 9* Print (External signal) * External PRINT and/or TARE switches may be installed as shown in the diagram. Momentary contact switches must be used. PRINT * TARE * RS232 Commands All communication is accomplished using standard ASCII format. Characters shown in the following table are acknowledged by the balance. Invalid command re- sponse "ES" error indicates the balance has not recog- nized the command. Commands sent to the balance must be terminated with a carriage return (CR) or carriage return-line line feed (CRLF). Data output by the balance is always terminated with a carriage return - line feed (CRLF).
