4 Basic Operation
4.1 Power On/Off
Press the On/Off key to turn the power on and off.
The * sign is displayed when the balance is powered by the AC
adapter and is in standby mode.
When an object is lying on the pan, the blinking [ on 0 ] is displayed. In such cases,
remove all the objects on the pan.
If a unit other than “g” (gram), “mg” (miligram) or “ct” (carat) is selected as Unit A,
the unit automatically changes to “g”.
4.2 Weighing
Place a sample on the balance and close the windshield door.
A circle will be displayed after the measurement has stabilized.
Read the measurement while the circle is displayed.
The circle will not be displayed or will flicker if the balance is
subject to disturbance such as vibration. Take appropriate
measures to stabilize the balance.
The bar graph indicates the current load in relation to the
balance’s weighing capacity. As the load approaches the
weighing capacity, the bar extends towards the right.
When the weight of an object exceeds the balance’s weighing
capacity, [o-Err] is displayed.
If the pan is removed and the zero-point falls below the original
zero-point, [u-Err] is displayed.
4.3 Zero Adjustment
Press the Zero/Tare key.
Wait until the display becomes stable (the M sign
flashes), and set the display to “0”.
While the zero point is accurately maintained, the
[→0←] sign is displayed.
4.4 Tare (pan)
Place the tare (pan) on the balance and press the
Zero/Tare key.
When the display becomes stable, “0” is displayed.

This operation is called “tare” and “Net” is displayed
while the weight of the pan is being set.
After the weight of the pan has been set, if a sample is placed in the container the balance will
display the weight (net weight).
* When a tare range is set, the weighing capacity is reduced accordingly.
Weighing capacity = original weighing capacity – pan weight
Even after the weight of the pan has been set and the display is set to “0,” the value indicated
by the bar graph includes the pan weight.
4.5 Set a Gross Weight
Press the Function key while the weight of the pan is
being set.
The gross weight, which is the sum of the pan weight
and the weight of the sample put in it, is displayed.
The B/G sign is displayed while the gross weight is
being displayed.
Pressing the Function key will toggle the display
between net weight and gross weight. (Unit B (net
weight) is also displayed if it has been selected.)
Caution:
1. A gross weight can only be displayed when the balance functions as a weighing machine.
2. When a gross weight is displayed, you cannot set a tare range. You can only adjust the
zero-point.
4.6 Single-touch Response Setting
This function allows you to switch the response of the balance with a single touch of the Set
button.
The balance will be subject to different levels of vibration depending on where it is placed.
Adjusting the balance’s response according to the magnitude of vibration reduces the variation
in its display and the time required for the display to stabilize.
Pressing the Set key once displays the current settings ([norMAL] etc.).
Pressing the Set key again toggles the display between [norMAL→SLoW→FASt].
After the balance settings have been completed, the display automatically returns to the
weighing mode.
This function corresponds to the settings [5. rE. *] and [6. Env. *] of Function 1, and the
settings in Function 1 are also changed at the same time.
(Continued on next page.)

Corresponding settings in
Function 1
Set key Meanings Description
6. EnV. 5. rE.
FASt FAST
The balance responds quickly but it
is easily affected by vibration 0 1
norMAL NORMAL The balance’s response is
somewhere between fast and slow 0 3
SLoW SLOW
The balance responds slowly but is
not easily affected by vibration 1 3
(Refer to “Section 5: Function 1” on page 15 for further information on Function 1.)
In [6. EnV. *], [0] indicates a fast response. Use this setting when the balance is
subject to a low level of vibration.
[1] indicates a slow response. Use this setting when the balance
is subject to a high level of vibration.
In [5. rE. *], [1] indicates the fastest response. Use this setting when the
balance is subject to a low level of vibration. As the number
approaches [5], the balance’s response becomes slower but it is
also less affected by vibration.
* To adjust the response more finely, use Function 1.
Caution
This function is unavailable when the gravimeter or addition function is enabled.
4.7 Data Output
Measured data and GLP data can be output to a personal computer, printer, or similar device
via the built-in RS-232C interface. In the factory default setting, pressing the Print key once
will output the current measured value when the measurement becomes stable.
[] is displayed while the data is being output.
Refer to “Section 5.5: Interface” on page 20 for further information on the output settings.
4.8 Hanging Measurement
The balance is equipped with a hanging hook to suspend a hanging pan for weighing.
Perform hanging measurements when weighing electromagnetic, electrostatic, or
high-temperature samples that cannot be accurately weighed on the normal pan.
Remove the pan and gently tilt the balance backward.
Take care that the door does not fall off.
(Continued on next page.)

14
Caution
1. Tools (hanging pan etc.) suspended from the hook are regarded as a tare (pan). Weights
equal to the weighing capacity cannot be measured.
Measurable weight = Weighing capacity – Total weight of tools suspended
2. Be sure to close the cover of the hanging hook when not in use to prevent dust from
entering the balance.
Hook for hanging
measurements
Loosen the screw and turn the
cover 90°. Then tighten the
screw to secure the cover.
