When the function tran set on, the rS232 is actived
2.
Baud rate is selected 4800 or 9600 when the function t.b.r. set 4800 or 9600.

SeTTInG THe acceleraTIon To GraVITY MoDe
1. Press [TARE] and [UNITS] first, then press [ON/OFF], while keeping [TARE] and [UNITS]pressed, the
display will show “Set”, then press the [unITS] several times until the display show ”Grav” press [Tare]
the display show “on” press the [HolD] the display show “oFF” .When the display show “on” means
acceleration to gravity is actived. When the display show “oFF” means acceleration to gravity is inactived.
2. When acceleration to gravity is actived press [on/oFF] turn the power off, then press [on/oFF]
turn the power on, then press [unITS] key 3 seconds enter to acceleration to gravity mode .1). when
the display show “C9.○ 00” ( ○ for flash digit ) first setting the local gravity.2). press [TARE] key again,
rightward flash digit, 3).press [ HOLD ] key, increase digit input the gravity value, press [UNITS] the
display enter to another local acceleration to gravity mode.
3. When t
he display show “U9.○ 00” ( ○ for flash digit) repeat the steps 1)-3) .press [UNITS] the display
will return the normal weighing mode.
