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: 1000g ± 0.1g SK-2000: 2000g ± 0.2g

SK-5000: 5000g ± 0.5g SK-10K: 10kg ± 1g

SK-20K: 20kg ± 2g SK-30K: 30kg ± 2g

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 to be displayed and press the

[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

to be displayed and

press the [RE-ZERO] key. The scale will show end and the

scale will automatically return to the weighing mode.
