5. OPERATION
5.1.
Turn the Power ON and OFF
1. Press the ON:OFF key to turn the power ON.
All of the symbols are displayed as shown above.
(About units: Only the available units will be displayed.)
Only when operated using the batteries, the balance subsequently performs a
countdown using the underscore on the display.
The display turns off except for a weighing unit and the decimal point.
The balance waits for the weight value to become stable, and then, zero will be
displayed along with the ZERO indicator (power-on zero).
The range for power-on zero is within ±50% of the weighing capacity around the
calibrated zero point.
If the power is turned ON while there is a load beyond this range, the balance will be
tared to zero and the NET and ZERO indicators turn on.
For the EJ-54D2, only when operated using the batteries, the weight value flashes
for a certain period of time after power-on zero. While the weight value is flashing,
weighing is possible. But the balance may not be stable enough depending on the
prior status
of power to the balance. So, for more accurate weighing, wait for the
weight value to stop flashing before weighing.
2. Press the ON:OFF key again to turn the power OFF.
Auto power-off function
It is possible to have the power automatically turned OFF, if the zero band display
(band width: ±4d from the zero point, d=readability (scale interval or “division”)
continues for approximately 5 minutes. Refer to “
8.5. Function List
” and set the
function to “
poff
”.
5.2.
LCD Backlight
The LCD backlight will turn on when the weight value changes more than 4d (4 x
readability (scale interval or “division”)) or any key operation is performed. When the
weight value becomes and stays stable for a certain period of time, the backlight will
automatically turn off. There is also a setting that the backlight is always on or off. For
details, refer to the item “
ltUp
” of “
8.5. Function List
”.
