Other Calibration Modes (Calibration Mode Selection 3)
The 212/212X has five additional modes that can be used to perform
calibration. Three of the modes require a test load or test weights, one
requires the scale to be empty (and at zero) and the last uses the
calibration “C” numbers from a previous calibration.
Dual-Point with Zero (First Zero) Calibration
This is a standard calibration method requiring one weight, an empty
scale and has one conversion factor. This method uses two calibration
points (CAL1= and CAL2=) to establish a zero (no load) calibration value and
to span the indicator. The two points correspond to zero weight and the
test load or test weight and can be applied in any order. This method
should be used for first-time calibration and complete recalibration.
CAL1= – First Calibration Weight
1. The display will show CAL1=0. This is the first of two calibration
weights. This weight could be ZERO (NO LOAD) or the TEST
WEIGHTS (TEST LOAD).
2. Press the ENTER key to view the current setting.
3. If the first calibration weight is to be ZERO (NO LOAD), press the
ENTER key.
4. If the first calibration weight is to be the TEST WEIGHTS (TEST
LOAD), use the numeric keys to input the value of the test weights.
5. Place the weights on the scale platform, then press the ENTER key.
6. Starting at the left and proceeding right, a series of dashes will
appear on the display.
7. Next, starting at the left and proceeding right, the dashes will
disappear, after which the display will show: CAL2=.
