Calibration
CHAPTER 2: CALIBRATION
Getting Started
The Hardy Filler/Dispenser can be calibrated two ways. The
first is with the Hardy C2
®
Second Generation calibration
which requires no test weights. C2
®
Calibration is one of
Hardy’s Core Technologies. We will describe the C2 Cali-
bration process in this chapter. The second calibration tech-
nique is called traditional calibration which requires certified
test weights. For detailed information about traditional cali-
bration See The HI 3010 Service Manual. It is important to
note that the procedures contained in this section either
explicitly stated or implied should be followed to guarantee
the performance of the instrument. Alternatives to the proce-
dures 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 points have
been installed so that nothing is binding the weigh-
ing 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 sensor is mounted so that
100% of the load (Vessel with Contents) vertically
passes through the load cell always at the same
point. (See Fig. 2-1)

Electrical Check Procedures
Step 1. Check to see that there is power to the controller.
• If there is power to the controller The front
panel display should be lit.
Step 2. Check to see that all communication and power
cables are securely fastened to the connectors on
the rear panel.
C2 Quick Calibration From the Front Panel

appears. (See Fig. 2-2)
Step 2. Press the down arrow until the cursor is in front of
CALIBRATION. (See Fig. 2-2)
Step 3. Press the Enter button. The CALIBRATION Menu
