14 Calibration (Adjusting the Scale)
The scale is an instrument which weighs the “weight” and displays its “mass”.
Calibration is the adjustment function so that the scale can weigh correctly.
There are three steps to calibration.
Gravity Acceleration Correction ....When a calibrated scale is moved to a
distant place, the scale can correctly weigh
by adjusting to a new local gravity
acceleration.
Refer to the “gravity acceleration table” on
the next page.
Calibration of the Zero Point........ When there is nothing on the pan, it is the
function that performs adjustment so as to
display the zero point mark .
The zero point, is the fundamental starting
point to weighing, and influences the
performance of scale.
Span Calibration .......................... The function that adjusts the span with a
calibrated mass so that the scale can
accurately weigh anything within the
weighing capacity.
Comment Span means the range of weighing
capacity. Use a calibration mass at least two
thirds of the weighing capacity.
Comment
Caution
It is necessary to calibrate the HV-G series using a mass of the OIML class M1 or
equivalent.
Periodically check the accuracy of weighing. Calibrate the scale, if it is moved to
another location or the environment has changed.
It is not necessary to correct for the gravity acceleration, when calibrating your
scale with the calibration mass at the place where your scale is used.
