1. 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.
1.3 Safety Precautions
Verify that the input voltage range printed on the data label and the plug type matches the local AC power
to be used.
Make sure that the power cord does not pose a potential obstacle or tripping hazard. Use the balance only in dry locations. Do not drop loads on the pan. Use only approved accessories and peripherals. Operate the equipment only under ambient conditions specified in these instructions. Disconnect the equipment from the power supply when cleaning. Do not operate the equipment in hazardous or unstable environments. Service should only be performed by authorized personnel. Do not position the balance such that it is difficult to reach the power connection.

2.4 Leveling the Equipment
The Explorer has an illuminated level indicator as a reminder that the balance should be leveled for accurate weighing. There is a level bubble in a small round window on the front of the Base. To level the balance, adjust the Leveling Thumbwheels at each corner until the bubble is centered in the circle.
Be sure the equipment is level each time its location is changed. Note: The feet cannot rotate. The Thumbwheels must be used for leveling.
See the Level Assist screen in the Information Menu.
To see the Level Assist menu, touch More on the bottom-right corner of the main screen. Then touch Level Assist.
The Level Assist screen shows which direction to turn the thumbwheels to center the level bubble.
2.2.6 Installing the Weighing Pan & Wind Shield – Non-Draft Shield Models Note: Assembly instructions also apply to models with the suffix M or N.
1. Place the four Support Caps onto the Balance as shown.
2. Place the Weighing Pan on the Support Caps
3. Place the Wind Shield onto the Balance as shown.
Note: The balance can be operated without the Wind Shield. However, depending on ambient conditions the displayed results may be slightly less stable.
2.3 Selecting the Location
Avoid excessive vibrations, heat sources, air current, or rapid temperature changes. Allow sufficient space.
Note: Interface cables connect to the terminal. The terminal can be detached and mounted on a wall or positioned on a table separate from the balance.
Caution: For use with CSA certified (or equivalent approved) power source,
which must have a limited current output.

2.9 Initial Calibration
When the Balance is first installed, and when it is moved to another location, it must be calibrated to ensure accurate weighing results. The Explorer Balances have built in AutoCal which can calibrate the balance automatically and does not require calibration masses. If preferred, the balance can be manually calibrated with external masses. Have the appropriate calibration masses available before beginning calibration. Refer to the Calibration Section for masses and calibration procedure.
