Calibration Instructions for the 

Standard Version of the SJ-H/HS series

When is to Calibration Required? 

Calibration may be required when the SJ-H/HS series initially installed or if the scale is 

moved a substantial distance. 

Calibration using a Calibration Weight 

1.  Entering calibration mode.

Press the [ON/OFF] key to turn the power off.  While pressing 

both the [RE-ZERO] and [UNITS] keys, press the [ON/OFF] key. 

Then 

 Cal  

  will be displayed. 

 Cal  

 can also be displayed by removing the calibration switch 

cover at the bottom of the device and pressing the calibration 

switch while the device is in the Weighing Mode. 

2. Zero 

calibration

Press the [RE-ZERO] key to calibrate zero. 

 Cal0 

 will be displayed. 

Wait for the Stable Indicator to be displayed, then press the [RE-ZERO] key.   

 Calf 

 will be displayed after a few seconds.  Press the [UNITS] key to perform only a 

Zero Calibration.    The scale will then automatically return to the Weighing Mode. 

3. Span 

calibration

 When 

 Calf 

 is displayed, place the weight at the center of the platform.  Wait for the 

Stable Indicator to be displayed, then press the [RE-ZERO] key.    The display will show 

 end 

  and the scale will automatically return to the Weighing Mode. 

See “SPECIFICATIONS” about the calibration weight. 

Calibration by Gravity Compensation 

If the acceleration of gravity at your location is not 9.798 m/s

2

 and you do not have 

calibration weights, the scale can be calibrated by compensating for the acceleration of 

gravity.    (Refer to “The Value of Gravity at Various Locations”.) 

1.  Setting a new acceleration value.

 When 

 Cal  

 is displayed, press the [UNITS] key and 

 9.798 

 will be displayed. Press 

the [RE-ZERO] key to increment the blinking digit and press the [UNITS] key to move the 

blinking digit. 

2.  Storing the value in the memory.

While pressing the [UNITS] key, press and hold the [RE-ZERO] key and release the 

[UNITS] key.    Then the display will show 

 end 

  and return to 

 Cal  

.    Turn the scale 

off to finish the procedure.
