Explorer™ Balances
Instruction Manual

INTRODUCTION

1.1 Description
The Explorer balance is a precision weighing instrument that will provide you with years of service if properly cared for. The Ohaus Explorer balances are available in capacities from 120 grams to 35,000 grams.
1.2 Features
Modular Design: Ohaus Explorer balances are composed of two interconnected modules: a Terminal and a Base. Depending on the user’s needs, the unit can be operated with the Terminal either attached to, or remote from, the Base, with a single interconnect cord 1 meter long.
Touch Controls: Quick, graphical access to all control functions, over a dozen applications and many features.
Touchless Sensors: can be assigned functions when activated: Zero, Print, Ionizer+Tare, Automatic draftshield door, ionizer etc. ”
Statistics: available in Weighing, Counting, Percent Weighing, Check Weighing, Dynamic Weighing, Filling.
Ionizer (EX225D/AD and EX225/AD only) The Ionizer generates bipolar ions continuously by DC corona discharge separately from positive and negative discharge electrodes and directs the ionized air onto the charged body to eliminate static electricity. The generated ions are well-balanced in polarity and can eliminate static electricity regardless of the polarity of the charged body.
Static electricity
Generally, insulators such as plastics are prone to be charged with static electricity when the ambient relative humidity is below 45%RH. This may affect weighing and cause a measurement error of several milligrams. The Ionizer can eliminate static electricity very effectively.
How to activate the Ionizer
The Ionizer can be activated or turned off by either the touchless sensors (see section 5.4.9) or through the function icons by pressing the Ionizer icon on the application home screen.

4.10 Density Determination
The Explorer can be used to determine an object’s density. Four types of density determination can be made:

1. Solids more dense than water
2. Solids less dense than water
3. Liquid density
4. Porous material (impregnated with oil)

A density determination kit is designed to be used with Ohaus Explorer balances. Illustrations in this procedure refer to the density kit. However, you may use whatever lab apparatus that suits the requirements for density measurements. The balance software includes a built-in reference density table for water at temperatures between 10°C and 30°C. Review this entire section before attempting density measurements. When making density measurements the material should weigh at least 10 mg on an analytical balance and 100 mg on a precision balance.

Internal Calibration (Auto Cal™).
The value can be set from 3-11 hours.

5.3.5 AutoCal™ Adjustment
Use this calibration method to adjust the zero calibration point, without affecting the span or linearity calibration.
Calibration Adjust may be used to adjust the result of the Internal calibration by +100 divisions.
Note: Before making a calibration adjustment, perform an Internal Calibration. To verify whether an adjustment is needed, place a test mass equal to the span calibration value on the pan and note the difference (in divisions) between the nominal mass value and the actual Balance reading. If the difference is within +1 division, calibration adjustment is not required. If the difference exceeds +1 division, calibration adjustment is recommended. (See Table 5-1, below.)
Example:

Actual weight reading:
Expected weight reading:
Difference Weight (d):
Difference weight in digits:| 200.014
200.000 (Test mass value)
0.014
–14 (Adjust value)
---|---

To perform a Calibration Adjustment, touch Auto Cal Adjustment from the Calibration Menu; Enter the value (positive or negative divisions) to match the difference noted earlier in the procedure and press√ .
Recalibrate using Internal Calibration. After calibration, place the test mass on the pan and verify that the mass value now matches the displayed value. If not, repeat the procedure until Internal Calibration reading agrees with the test mass.
Once completed, the balance stores the Adjustment value and the display returns to the current application.
5.3.6 Span Calibration
Span calibration uses two calibration points, one at zero load and the other at specified full load (span).
Refer to Table 5.1 for Span values. For detailed calibration mass information please see the specification tables in section 9.
Note: Factory default settings are shown in bold.
TABLE 5-1 Calibration Masses

With the balance turned ON and no load on the pan, touch Span Calibration to initiate the procedure. Additional calibration values to be used are shown on the display. The best accuracy is achieved using the mass closest to the full span value.
Note: To change the span calibration point, touch the alternate weight shown on the display. Follow the screen instructions and place the specified calibration weight on the scale when prompted to do so. When complete, the display shows the Span calibration status and returns to the current application.
5.3.7 User Calibration
User Calibration is used to calibrate the balance using a user defined mass.
With no load on the scale, press User Calibration from the calibration sub- menu.
The display shows the current full load (span) calibration point and calibration unit of measure.
To change the value to a user-defined weight, touch ENTER VALUE.
Enter the weight via the popup screen. The balance then prompts for the User- defined weight.
Place the specified calibration weight on the balance and the calibration process completes.
The display shows status, then returns to the current application.
5.3.8 Calibration Test
Use Calibration Test to compare a known calibration weight against the stored span calibration data. With no load on the scale, press Cal Test to begin the process.
The balance captures the zero point, then prompts for the span value.
The display shows status, followed by the difference between the current calibration weight and the stored calibration data.
After 3 seconds, the display returns to the current application.

When the balance is used in trade or a legally controlled application it must be set up, verified and sealed in accordance with local weights and measures regulations. It is the responsibility of the purchaser to ensure that all pertinent legal requirements are met.
*For EX…N…models, please refer to Legal for Trade Setting and Sealing flyer for details.
LEGAL FOR TRADE SETTING AND SEALING
6.1 Settings
Before verification and sealing, perform the following steps in Order:

1. Verify that the menu settings meet the local weights and measures regulations.
2. Units menu should be reviewed. Verify the units turned On meet the local weights and measures regulations.
3. Perform a calibration as explained in Section 5.
4. Set the position of the Security Switch to the locked position.
5. Set Legal for Trade to ON in the Balance Setup menu.

6.2 Verification
A weights and measures official or authorized service agent must perform the verification procedure.
6.3 Sealing
After the Balance has been verified, it must be sealed to prevent undetected access to the legally controlled settings. Before sealing the device, ensure that the security switch is in the Locked position and the Legal for Trade setting in the Balance Setup menu has been set to ON.
If using a wire seal, pass the sealing wire through the holes in the security switch and Bottom Housing as shown. If using a paper seal, place the seal over the security switch and Bottom Housing as shown.

PRINTING

7.1 Connecting, Configuring and Testing the Printer/Computer Interface Use the built-in RS-232 Port to connect either to a computer or a printer. If connecting to a computer, use HyperTerminal or similar software. (Find HyperTerminal under Accessories/Communications in Windows XP.) Connect to the computer with a standard (straight-through) serial cable. Choose New Connection, “connect using” COM1 (or available COM port). Select Baud=9600; Parity=8 None; Stop=1; Handshaking=None.  lick OK. Choose Properties/Settings, then ASCII Setup. Check boxes as illustrated: (Send line ends…; Echo typed characters…; Wrap lines…)
Use RS232 Interface Commands (Section 9.6.1) to control the balance from a PC. Note: When the HyperTerminal configuration is complete, it will automatically print the results of a Cal Test operation, and echo print commands sent to the scale. Printer Connection
Two printers compatible with Explorer Balances are available from Ohaus. (See Section 9.) Connect a straight-through serial cable to the scale’s RS232 port. See sample Print Output Formats below. Two printers compatible with explorer balances are available from Ohaus. Connect a straight through serial cable to the scale

7.2 Printout Examples
Examples for each Application are shown with all items turned ON in the Print Content menu. The default values
for Header lines 1-5 are also shown.
Note: If a Library name has been selected, “Library Name:” will appear below “Application” in the printout.
User name and Signature line will show the user name which is logged in at present. If admin account is logged in, Admin will appear.

Note: In order to print Net weight, the Tare key needs to be pressed.

Internal Calibration, Span Calibration and User Calibration:

Note: User calibration is for InCal models only.
The CAL TEST printout is automatically printed when a Calibration Test is performed.

7.3 Output Format
The Result Data, and G/N/T data, is output in the following format.

1.  In certain cases, a Label field of up to 11 characters is included.
2. Each field is followed by a single delimiting space (ASCII 32).
3. The Weight field is 9 right justified characters. If the value is negative, the “–“ character is located at the immediate left of the most significant digit.
4. The Unit field contains the unit of measure abbreviation up to 5 characters.
5. The Stability field contains the “?” character if the weight reading is not stable. The Stability field and the following Space field are omitted if the weight reading is stable.
6. The G/N field contains the net or gross indication. For net weights, the field contains “NET”. For gross weights, the field contains nothing, “G” or “B”, depending on the GROSS INDICATOR menu setting.
7. The Termination Characters field contains CRLF, Four CRLF or Form Feed (ASCII 12), depending on the LINE FEED menu setting.

9.5 The USB Interface
The Ohaus USB Interface is a unique solution to the problem of connecting a balance to a computer using a Universal Serial Bus (USB). USB devices are categorized into classes such as disk drives, digital cameras, printers, etc. Balances do not have a commonly used class so the Ohaus USB interface uses a generic interface based on the RS232 serial standard.
Data sent from the balance to a computer is in USB format. The USB data is directed to a virtual port. This port then appears as an RS232 port to the application program.
When sending a command from a computer to the balance, the application program sends a command to the virtual port as if it were an RS232 port. The computer then directs the command from the virtual port to the computers USB connector where the balance is connected. The port receives the USB signal and reacts to the command.
System Requirements

• PC running Windows 98® , Windows 98SE® , Windows ME® , Windows 2000® , Windows XP® or Windows 7® , Windows 10® .
• Available USB port (Type A, 4-pin, female)

USB Connection
The balance’s USB port terminates with a mini USB.
A USB Cable (Mini B/male to type A/male) is required (not supplied).

1. Ensure that the balance is powered on and working properly.
2. Power on the computer and verify that its USB port is enabled and working properly.
3. Plug the cable’s USB connectors into the computer’s USB port and the balance’s USB port. Windows® should detect a USB device and the New Hardware Wizard will be initialized.

Virtual Port Software Installation

1. Download the USB driver from the following address on the OHAUS website and then double click to install.
   https://us.ohaus.com/en-US/Support/Softwareand-Drivers

2. After the installation is finished, click Finish, the virtual port should be ready to be used. Windows® typically adds the virtual port in sequence after the highest number COM port. For example, on PC’s equipped with up to 4 COM ports, the virtual port will be COM5.
   When using the USB interface with programs that limit the number of COM port designations (e.g. Ohaus MassTracker allows only COM1, 2, 3, & 4), it may be necessary to assign one of these port numbers to the new virtual port.

This can be done in the Port Settings of the Device Manager utility, found in the Windows Control Panel.
Balance Setup for USB Interface
A) The Ohaus Interface is preset to communicate using the following settings: 9600 baud, 8 bit, no parity, no handshake, 1 stop bit. This is a fixed setting and cannot be changed.
B) Configure the balance to the desired USB and printing parameters.
SETUP DEFINITIONS

PRINT / Stable – On
PRINT / Auto Print – Continuous
PRINT / Auto Print – On stability
PRINT / Auto Print – Interval
PRINT / Auto Print – Off
USB / Baud, Parity, Handshake| Balance transmits stable data only.
Balance repeatedly sends data as fast as possible. Balance automatically outputs data upon stability.
Balance sends data every (xx) seconds.
Only sends data when PRINT is pressed.
Set parameters to match printer or computer.
---|---

Operation
USB OUTPUT
With the Adapter installed the balance will operate in one of the following three ways:

• USB = On, Auto Print = Off, Stable = On or Off
  Press PRINT to send the display data based on the settings in the Menu.
  If Stable is set to On, the balance will wait for a stable reading before sending data.
  If balance has connect USB flash diver, the data will automatic go to USB.

• USB = On, Auto Print = On, Stable = On or Off
  The balance will automatically send data.
  If Stable is set to On, only stable values will be sent.

• USB = Off
  The interface is turned off.

Data sent from the Interface is in standard ASCII format terminated with a [CRLF] (carriage return-line feed).
The output format is as follows:

[weight] [space] [unit] [space] [stability indicator] [space] [legend] [CR] [LF]| 10 characters (right justified)
1 character
5 characters max (left justified)
1 character
1 character “?” when unstable or below min-weight, blank when stable
1 character
10 character TOTAL, hh:mm:ss (time interval), etc.
1 character
1 character
---|---

Output examples: (Note: * and _ indicate spaces)

• Manual, Continuous or On-Stable printing unstable reading
• Interval Printing (example:15sec interval) unstable reading
• Accumulate Mode (Manual printing only)

USB INPUT
The balance will respond to various commands sent via the interface adapter.
Terminate the following commands when with a [CR] or [CRLF].
