IV.Operating
1Preparation
lUnpacktheboxandremoveall thepacking.Takeoutbufferspongeinthewind-proof
coverand install pan.
lPutthebalance on a stableworking tablefree fromvibration, sunshineand airflow.
lAmbienttemperature:
Balance ofgrade:
:20℃±5℃withafluctuationoftemperaturenot
greaterthan1℃/h.
:20℃±7.5℃withafluctuationoftemperaturenot
greaterthan5℃/h.
lRelativehumidity:
Balance ofgrade: :＜50%～75%；:
:＜50%～80%.
lOperatingvoltage:AC100V~240V, 50/60Hz.
2 Operation
lCheckthelevelmeterbeforeoperation.If thebubbleisnotin thecenter, adjustthelevel
legstomakethebubbleinthecenter.
lThebalance adoptssofttouchbuttons,soit canbecontrolledwithmulti-keyboards.Itis
easytooperate.Functionchangeand selectioncanberealizedsimplyby depressingthe
correspondingbuttons.
