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
display shows the stable measurement indication [H] and the zero weight
indication [I].
• Select the desired weighing unit (gram, carat, pennyweight or grains) by
pressing on the mode button [C]. The selected unit is shown on the display
[D].
• Place the weight on the balance. Wait until the measurement is stabilized, and

until the measurement is stabilized. Press the tare button [F] to reset the scale
to zero; the word 'ZERO' [I] is indicated on the display.
• The relative measurement option allows using multiples of a basic weight in stead
of the weight itself.
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
calibration weight and wait until the word 'PASS' appears. The scale is now
