wait until the measurement is stabilized, indicated by a circle [H] in the display
before reading the value.
Use the On/Off button [A] to switch on the scale. After initialization, the LCD

The relative measurement option allows using multiples of a basic weight in stead

To use the relative measurement option, place a basic weight on the scale, and
press and hold the counting button [G] until the word 'PCS' appears [J]. With the
mode button [C] the count can be set to 25 – 50 – 75 or 100 (%). Store the
selection by pressing the counting button [G] again.
Examples:
When the basic weight is set to '100 PCS', removing weight until the display shows
'75' (%) means that 3/4
When the basic weight is set to 25 PCS, adding weight until the display shows '50'
means that on the scale is two times the basic weight. Adding weight until the
display shows '100' means that the basic weight times 4 is now on the scale.
Quit the relative measurement mode by switching the scale off and on.
Note that the scale has an auto-power off function. The scale will switch off after
±30 seconds when no activity is detected.
To calibrate the scale, a weight of exactly 500g (or 2500 carat, 321.5075
pennyweight or 7716, 1792 grains) is needed.
Press and hold the mode button [C] until the word 'CAL' flashes. Put down the
