CHAPTER 5: CALIBRATION
About Chapter 5
Chapter 5 pertains to the calibration procedures for the
HI 3010 Filler/Dispenser. Alternatives to any procedures
implied or explicitly contained in this chapter are not recom-
mended. In order for the Filler/Dispenser to work properly, it
must be calibrated prior to operation. Be sure to follow all
the procedures completely to insure that the weights read by
the Filler/Dispenser are accurate. It is very important that the
user and service personnel be familiar with the procedures
contained in this chapter, before installing or operating the
HI 3010 Filler/Dispenser.
Getting Started
The HI 3010 Filler/Dispenser can be calibrated two ways.
The first is the Hardy C2
®
Second Generation calibration
which requires no test weights. Hardy C2
®
Calibration is
one of the Core Technologies. We will describe the C2 Cali-
bration process in this chapter. The second calibration tech-
nique is called the traditional calibration which requires
certified test weights. It is important to note that the proce-
dures contained in this section either explicitly stated or
implied should be followed to guarantee the performance of
the instrument. Alternatives to the procedures listed here are
not recommended.
Before you can calibrate the instrument you first need to
check to see if the system is ready to be calibrated.
Binding
Step 1. Due a visual check to see if the load cells have been
installed so that nothing is binding the load cell or
other parts of the weighing system. Make sure that
nothing is draped over the scale or vessel such as a
hose, electrical cord, tubes or other objects.
CAUTION: BINDING ON A SCALE / VESSEL OR LOAD CELL
DOES NOT ALLOW THE LOAD CELL FREE VERTICAL MOVE -
MENT AND MAY PREVENT THE INSTRUMENT FROM RETURN -
ING TO THE ORIGINAL ZERO REFERENCE POINT .
Step 2. Check to see that the load cell is mounted so that
100% of the load (Vessel with Contents) vertically
passes through the load cell. (See Fig. 5-1)

Electrical Check Procedures
Step 1. Check to see that there is power to the controller.
a. If there is power to the controller The front
panel display should be lit.
b. If the display appears with a value the unit is
ready for calibration.
Step 2. Check to see that all communication and power
cables are securely fastened to the connectors on
the rear panel.
C2 Calibration From the Front Panel
Step 1. Press the Setup/3 button. The Configuration Menu
appears. (See Fig. 5-2)
Step 2. Press the down arrow until the cursor is in front of
CALIBRATION. (See Fig. 5-2)
Step 3. Press the Enter button. The CALIBRATION Menu
appears with the cursor in front of CAL TYPE C2.
(See Fig. 5-3)
NOTE: If the cursor is in front of CAL TYPE TRAD,
press the left or right arrow buttons until CAL
TYPE C2 appears.
