Class 1 Tolerance. Calibration masses are available as
accessories.

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.

Calibration
Explorer
Pro
Balances offer a choice of five calibration methods: Automatic Calibration (AutoCal
TM
), 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.
•
AutoCal
TM
Automatic calibration (AutoCal
TM
) 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.
