1. GETTING TO KNOW YOUR BALANCE
Please read through this section carefully, as it contains important information for safe and economical operation of
yourNavigatorTM balance.
1.1Introduction
Thank you for deciding to purchase a NavigatorTM balance from Ohaus. This versatile, portable balance offers a high
level of operating convenience and useful functions to make accurate measurements usually obtained from higher
priced laboratory instruments. A custom LCD panel has a large 6 digit, 7 segment display which indicates the weight
value of an item being measured and a 6 character 14 segment display which spells out items selected in the menus.
In addition, the display contains text which indicates the active operating mode of the balance. Arrow indicators in
the display prompt the user as to what panel keys are to be pressed to initiate a change. Built-in RS232 communica-
tion is standard on all models and allows communication with printers or computers.
Panel controls are clearly marked as to their function with large zero/tare buttons on either side of the front panel.
Operation and setup of the balance is straightforward and easy. Setup is simple with 4 cursor keys, straightforward
menus, and prompts that easily guide you through the process.
NavigatorTM is designed with contours for easy cleaning and has a sealed front panel and spill gutter to direct liquids
off the balance. For leveling purposes, all models are equipped with adjustable feet and a level indicator.

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 upYour 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
displaysLOWBAT. Turn the balance OFF. Remove the
batteriesandreplace.
Stabilization
Before initially using the balance, allow time for it to
adjust to its new environment. Recommended warm up
period is 5 minutes.
Calibration
Referto paragraph 3.3 andcalibrate 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.
• CalTest - 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.

Calibration Menu Protection
NOTES:
• Calibration may be locked out to prevent unauthorized
personnelfrom changing calibration.Ifcalibration has been
locked out, you can only access Cal Test.
•To lock out calibration menu, after calibration, refer to the
sectiontitled Menu Lock-OutProtection, paragraph 4.12.
Calibration Masses
Beforebeginning calibration, makesure masses are
available. If you begin calibration and realize calibration
masses are not available, exit the menu. The balance will

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.

14
3.3.1Internal Calibration (InCALTM)
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
balancehas warmed up to operatingtemperature.
• Press the Setup button, CAL is displayed.
• Press Enter button, CAL TYP is displayed.
• Press Enter button, CALTYP 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).
Thebalance automatically resumescalibration.
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 toWEIGH mode.
IMPORTANT !
DO NOT DISTURB THE BALANCE DURING
CALIBRATION. IF THE MESSAGE UNSTBL
IS DISPLAYED,THE BALANCEWAS 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...

3.3.2Calibration Message
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, CALTYP 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 InCal
TM
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.

3.3.3Calibration Adjust
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 theinternal calibrationprocedure.
• 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
readingis higher or lower, proceed.
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYP 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 readingandremove mass from
pan.
• Performthe 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.

3.3.4Span 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. 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
210gbalance.
Procedure
• Clearthe pan.
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYP 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 PUTWEIGHT 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 toWEIGH mode.
• Span calibration is completed.
• Remove calibration mass from the pan.

3.3.5User 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. To use this calibration feature, proceed as follows:
(FLASHING)
• Clearthe pan.
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYP is displayed.
• PressEnter button.
• Press and scroll to select USER calibration,
CAL TYP USEr is displayed.
• Press Enter button, the display indicates the last
calibration mass value which was entered with the
first digit flashing. (Sampleillustrates 200g).
• Press to change value of digit and
button to advance to next digit. Enter the desired
mass value for your balance. This number must be
at least 50% of the full span value.
• After entering value, 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).
Thebalance automatically resumescalibration.
• Display changes to PUT WT 200 g.
