1. GETTING TO KNOW YOUR BALANCE
Please read through this section carefully, as it contains important information for safe and economical operation of your
Explorer Pro Balance.
1.1 Introduction
Thank you for deciding to purchase a Explorer Pro Balance from Ohaus. Thanks to a new modular design, your Explorer Pro
Balance lets you adapt the balance to your changing needs. Remote displays, upgraded displays which can be table, wall or
tower mounted are available as accessories. It offers a high level of operating convenience and useful functions to make

DO NOT install the balance:
•Next to open windows or doors causing drafts or rapid
temperature changes.
•Near air conditioning or heat vents.
•Near vibrating, rotating or reciprocating equipment.
•Near magnetic fields or equipment that generates magnetic
fields.
•On an unlevel work surface.
•Allow sufficient space around the instrument for ease of
operation and keep away from radiating heat sources.
2.2 Selecting the Location
The balance should always be used in an environment which is free from excessive air currents, corrosives, vibration, and
temperature or humidity extremes. These factors will affect displayed weight readings.
2.3 Setting Up and Leveling the Balance
Exact horizontal positioning and stable installation are prerequisites for repeatable results. To compensate small irregularites or
inclinations at the location, the instrument can be leveled.

It is recommended that masses must meet or exceed ASTM
Class 1 Tolerance. Calibration masses are available as
accessories.
3.2 Turning On the Balance
The Explorer Pro Balance is ready to operate after the the installation procedures are performed. When the balance is first turned on and it
completes its checks, and is calibrated, it can be used to weigh or tare materials without setting the menus. The balance is preset at the
factory to weigh in grams.
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.
LCD Display On/Off
To turn the balance LCD display 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.
Stabilization
Before initially using the balance, allow time for it to adjust to its new environment. The balance only requires to be plugged in to warm up.
Recommended warm up period is twenty (20) minutes. The internal circuits of the balance are powered when ever it is plugged into a power
source.
3.3 Calibration
Explorer Pro Balances offer a choice of five calibration methods: Automatic Calibration (AutoCalTM), Span Calibration, User Calibration,
Linearity Calibration, and Calibration Test.
• Span - Span calibration ensures that the balance reads correctly within specifications using two weight
values: zero and a weight value at 100% of the balance’s full capacity.
• 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 balances
weighing range, and a weight value at or near the balance’s specified capacity.
• User -User calibration is a method where the balance can be calibrated using a mass of known value by
entering that value into the balance.
• Calibration Test -Calibration test allows the stored calibration data to be tested against the current mass being
used for the test.
• AutoCalTM Automatic calibration (AutoCalTM) of the balance is accomplished by an internal mass.
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 Internal Weight Calibration and Calibration
Test.
•To lock out calibration menu, after calibration, refer to the section
titled Menu Lock-Out Protection.
•Linearity, Span and User calibration are disabled for Type
Approved/LFT balances.
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 accu-
rate weighing. Masses required to perform the procedures are listed
in the adjacent table.

3.3.3 Linearity Calibration
Linearity calibration utilizes three calibration points, one at zero, center span and full span. This method 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 specified capacity.
