Do not allow the balance to be immersed in water. Even though the balance complies with
IP code, the balance will not withstand being completely immersed in water.
The weighing pan, pan support and draft gate can be removed to clean the balance. Clean
by splashing with water.
Use the waterproof option RS-232C cable GX-07K, when RS-232C interface is used with
IP-65. AX-KO1710-200, a standard RS-232C cable, is not waterproof or dustproof.
3-4. Power Supply
Do not remove the AC adapter while the internal mass is in motion, for example, right
after the AC adapter is connected, or during calibration using the internal mass.
If the AC adapter is removed under the conditions described above, the internal mass will be
left unsecured, that may cause mechanical damage when the balance is moved. Before
removing the AC adapter, press the
ON:OFF key and confirm that zero is displayed.
When the AC adapter is connected, the balance is in the standby mode if the standby
indicator is on. This is a normal state and does not harm the balance. For accurate
weighing, keep the AC adapter connected to the balance and AC power unless the
balance is not to be used for a long period of time.
