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.
Pressing the RANGE key will
switch these ranges alternately.
When a sample is weighed using the
precision range with a minimum display of
0.01 mg 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
RE-ZERO 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.
