Weighing Range (EJ-54D2 only)
The EJ-54D2 has two weighing ranges available as follows:
Range 1 (low range) … 22 g×0.0002 g
Range 2 (high range)
…
52 g×0.001 g
Function settings available to select how the weighing range changes:
automatic range (
rng 1
) or manual range (
rng 0
).

Automatic range
 When the weight value exceeds the maximum value in the low
range, the weighing range automatically changes to the high range.
 When there is nothing on the weighing pan and the display shows zero
along with the ZERO indicator and the balance becomes stable
enough, the weighing range automatically changes from the high to the
low range.
When the ZERO indicator is not turned on or the taring operation is
being performed, the weighing range does not change. Press the
RE-ZERO key.
 When the RE-ZERO key is pressed and if the object on the
weighing pan exceeds 2% of the weighing capacity, the balance is
tared to zero, but the weighing range does not change.
If the object is 2% of or less than the weighing capacity, the balance
displays zero and clears the tare value. When the balance becomes
stable enough, the weighing range automatically changes to the low
range.
rng 0
Manual range
 Press the SAMPLE key when the display shows a weight value
(neither counting nor % display). The weighing range changes to
the high range at any load.
 To change from the high to the low range, press the SAMPLE key
when there is nothing on the weighing pan and the display shows
zero along with the ZERO indicator.
When the ZERO indicator is not turned on or the taring operation is
being performed, the weighing range does not change. Press the
RE-ZERO key and then press the SAMPLE key.
If the balance is stable enough when the SAMPLE key is
pressed, the weighing range changes to the low range.
 When the RE-ZERO key is pressed and if the object on the weighing
pan exceeds 2% of the weighing capacity, the balance is tared to zero.
If the object is 2% of or less than the weighing capacity, the balance
displays zero and clears the tare value.
In either case above, the weighing range does not change.

Display Hold Function
In stable measurements, this function can hold the weight value to read it easily. The
function holds the value except in the zero band (band width: ±4d from the zero point,
d=readability (scale interval or “division”)). The function releases the value when the
weight value changes more than the value set in the function mode. Also, when the
RE-ZERO key is pressed, the display hold is canceled and display becomes zero.
