☆ Key Points of the Procedure ☆
The following applies equally to all the measurement modes for weight measurement, counting, and percentages.
1.
After the balance is switched off, there is still enough current to display [ ]. This indicates that the AC adapter is
connected to an electrical outlet, but that the balance is turned off.
When the balance is switched on again, [ ] will disappear.
※If the balance is running on batteries and the unit is switched off, the display does not display [ ].
2.
The bar graph shows the current load status with respect to the capacity of the balance.
The nearer the [F] mark draws, the smaller the measurable weight becomes.
※Even when the display currently indicates zero with the tare subtracted, the weight
corresponding to the subtracted tare is indicated on the bar.
3.
When the balance remains stable, the stability indicator [○] remains
on. If the balance becomes unstable, the stability indicator [○] will disappear.
When a displayed value flickers or the stability mark flashes on and off, it is likely that the balance is being affected
by wind or other vibrations. Use the windshield or vibration dampers to protect against such adverse effects.
When the read-out indicator is reset to zero or the tare is subtracted, the balance indicates zero this way: [→ 0 ←].
4.
If the tare is subtracted, the indicator reads as follows: [→ T ←].( [→ T ←] is effective only when the lock switch is
off.)
*If the indication
deviates from the
true zero point by 1/4
of a graduation or
less,[→0←]
disappears.
5.
When the tare is subtracted, the measurable range is reduced.
Measurable Range = Capacity - Tare Weight
6.
If [o-Err] appears when a sample is loaded, the measurable range has been exceeded.
7.
In counting mode or percentage mode, if no sample is stored in memory the indicator will not change, even when
the measurement pan is pressed.
8.
The measurement mode that is activated when the balance is switched on will be the one that was active when last
switched off. For example, if the balance was switched off in counting mode, this counting mode will be reactivated
the next time the balance is switched on.
To print data on the balance, set "Output Control (71.o.c.)" to [2], [4], [5], or [7], so that only stable data will be
9.
printed (see "4.3 Interface Section" on page 14).
