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.

3.7 Functions and Their Icons
Seven Icons are initially available to operate the Balance and access the Menu. These Icons can be customized
based on user preference. For setup information, see User Settings.
3.7.1 Standby
Touch Standby to shut down the display.
Note: After initial start-up (Section 2), in Standby your balance needs no warm-up time and is
immediately available for weighing by touching the Start-up icon.
3.7.2 Printing Data
Touch Print to send the displayed value to a printer or computer via the active COM port.
Note: Ensure proper setup of connections, printing and interface parameters.
Note: Data may also be printed using the Touchless Sensors by configuring these for Printing.
Data may also be printed using the P command from a computer connected to the COM port.
3.7.3 Zero Operation
Remove the load from the pan and touch Zero to set the display to zero. When weighing pan is
empty, the >0< indicator turns on when the measurement is within + ¼ division (d) of the zero setting.
Note: The balance also features Auto Zero Tracking (AZT) that automatically maintains a Center of
Zero within the tolerances set in the AZT menu (see Balance Settings).
3.7.4 TouchLess Sensor Status
Explorer balances have four TouchLess sensors that can be assigned a unique function when
activated (e.g., zero, print, tare, Automatic draftshield door etc).
To assign a task for each TouchLess sensor, press Sensors.
Note: To activate a sensor, move an object over it (from a distance of 1-2 inches or 3 cm). The sensor
shows a green light and beeps when activated. If the sensor cannot be activated (sensor is disabled
during certain instances, like when the Menu is displayed) the sensor shows a red light.
3.7.5 AutoCal
When AutoCal is ON, the balance performs a self-calibration. AutoCal will automatically calibrate the
Balance (using the internal mass) each time a change in temperature significant enough to affect
accuracy, or after every 11 hours.
Touch AutoCal™to initiate. (Default status is ON.)
Note: Not available in ExCal
