			Weighing range				Available minimum display
		GH-252			GH-202		Available minimum display
		GH-252			GH-202
Precision range	0 g	to	101 g	0 g	to	51 g	0.01 mg 0.1 mg	1 mg
Standard range	101 g	to	250 g	51 g	to	220 g	0.1 mg	1 mg

The GH-252 and GH-202 are equipped with two ranges "precision range" and "standard range".

When weighing is started by pressing the ON:OFF key, the minimum display will be 0.1 mg.

Precision Range	Standard Range
Turn on the balance	Turn on the balance
Minimum display	Minimum display
0.1mg	0.1mg

Pressing the RANGE key will switch these ranges alternately.

When a sample is weighed using the precision range with a minimum display of

0.01mg and the weight value exceeds the precision range value, the minimum display

changes to 0.1 mg of the standard range. When removing the sample, the minimum display changes to 0.01 mg of the precision range automatically.

When a tare weight (container mass value) exceeds the precision range value, even if the sample is within the precision range value, 0.01 mg of the precision range can not be selected for the minimum display. In order to select 0.01 mg of the precision range, remove the tare weight and press

the key to cancel it.

When a minimum display of 0.1 mg or 1 mg is selected by the RANGE key, the minimum display is maintained even if the range is changed during weighing.
