3.2 Turning On the Balance
The balance is ready to operate after the installation procedures are performed. When the balance is first turned on and it completes its checks, it can be used to weigh or tare materials without setting the menus. It is recommended that you read this manual carefully and set the balance to operate for your specific applications using the procedures in Chapter 4 Setting up Your Balance and calibrate the balance before using. In this section, you will enter the menu for the first time. Do not worry if you are unfamiliar with the function of the buttons on the panel, the display provides the necessary coaching as you go along.

Power On/Off
To turn the balance ON, press the ON/OFF button (circled button with an I inside) located at the upper left-hand corner of the panel once. To turn OFF, press button again. NOTE: If the balance has been battery operated for a long period of time, and the batteries are low, the balance displays LOWBAT. Turn the balance OFF. Remove the batteries and replace.

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 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 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 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. Calibration test allows the stored calibration data to be tested against the current mass being used for the test. Can be set on or off. When set on, Span, User and Linearity calibration are locked out and cannot be used. 12

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.

3.3.1 Internal Calibration (InCALTM)
On NavigatorTM balances equipped with the InCalTM feature, calibration can be accomplished using the internal calibration 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.

Procedure
· 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.
IMPORTANT ! DO NOT DISTURB THE BALANCE DURING CALIBRATION. IF THE MESSAGE UNSTBL IS DISPLAYED, THE BALANCE WAS UNABLE TO ACQUIRE STABLE DATA DURING INTERNAL CALIBRATION. THE BALANCE WILL CONTINUE TO PERFORM INTERNAL CALIBRATION UNTIL READINGS STABILIZE. THE BALANCE WILL THEN COMPLETE THE INTERNAL CALIBRATION FUNCTION. TO EXIT INTERNAL CALIBRATION MODE BEFORE COMPLETION, PRESS ENTER OR SETUP BUTTONS. STABILITY CAN BE AFFECTED BY TEMPERATURE CHANGES, AIR CURRENTS, VIBRATION, ETC...

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 calibration. The display returns to WEIGH mode.

14

3.3.2 Calibration Message

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. · 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.
