8400-M022-O1 Rev K Model 190 Indicator
Multi-Point Calibration
This method requires up to four weights, an empty scale, and has up to four conversion
factors. This method uses up to five calibration points (CAL1=, CAL2=, CAL3=, CAL4=,
and CAL5=). The five points correspond to zero weight, up to three midpoint weights, and the
test load or test weight and can be applied in any order.
NOTE: This method can be used to correct for system nonlinearity.
CAL1= – First Calibration Weight
1. The display will show CAL1=. This is the first of five calibration weights. This weight
could be ZERO (NO LOAD) or the TEST WEIGHTS (TEST LOAD).
2. Press the TARE key to view the current setting.
3. If the first calibration weight is to be ZERO (NO LOAD), press the TARE key.
4. If the first calibration weight is to be the TEST WEIGHTS (TEST LOAD), use the
UNITS/ and Fn/ keys to input the value of the test weights.
5. Place the weights on the scale platform, then press the TARE 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=.
CAL2= – Second Calibration Weight
1. The display will show CAL2=. This is the second of two calibration weights. This weight
could be ZERO (NO LOAD) or the TEST WEIGHTS (TEST LOAD).
2. Press the TARE key to view the current setting.
3. If the second calibration weight is to be ZERO (NO LOAD), press the TARE key.
4. If the first calibration weight is to be the TEST WEIGHTS (TEST LOAD), use the
UNITS/ and Fn/ keys to input the value of the test weights.
5. Place the weights on the scale platform, then press the TARE 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: CAL3=.
