CALIBRATION
When to Calibrate
Calibration may be required when the scale is initially installed, if it is
moved a substantial distance, or in accordance with local regulations.
This is necessary because the weight of a mass in one location is
not necessarily the same in another location. Also, with time and use,
mechanical deviations can occur.
The Position of the [UNITS] key for the Calibration
The (k)g model has no [UNITS] key, but the key
for the calibration is located under the overlay.
Calibration Using a Calibration Weight
Calibrate the scale with the following calibration weight.
SK-1000:
SK-5000:
SK-20K:
1. Enter 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.
2. Zero calibration
Press the [RE-ZERO] key to calibrate zero. Cal0 will be displayed.
When you have proceeded to the display other than Cal0 , press
the [ON/OFF] key to turn the power off and start over again.
Wait for the stable indicator
[RE-ZERO] key. Calf will be displayed in a few seconds. If the
zero calibration only is to be done, press the [UNITS] key. The scale
will show end and automatically return to the weighing mode.
3. Span calibration
Place the weight at the center of the platform for accurate
calibration. Wait for the stable indicator
press the [RE-ZERO] key. The scale will show
scale will automatically return to the weighing mode.
