P10.x: Select the weighing unit that may be chosen by pressing UNIT/HOLD.
P12.x: Zero range for ON/OFF/ZERO button operation
If zero key can be activated, it can clear the TARE weight. If zero point is above the setting range, the indicator
will show “0ˉ ˉ ˉ ˉ”, and if zero point is below the setting range, “0_ _ _ _” will be shown.
P15.x: Zero tracking range
Choose the zero tracking range as per the stability of weighing system, accuracy and weight excursion. The
normal setting is +0.5d ~ +1.5d.
P16.x: Data filter intensity
The larger the chosen digit is, data filter intensity is stronger, and the speed of data updating is lower.
P17.x: Range of weight stability checking
If the variety of weight reading is within the setting range continuously for several times, the scale is
recognized as stable. The normal setting is +1d ~ +3d.
P18.x: Overload range that can be displayed (when weight is larger than range, “ˉˉˉˉˉ”will be shown):

Details about RS232
7.1 RS-232 connects between scale and Host:
Scale ------------------------------------------Cable--------------------------------------Host
(DB9 female)-------------------(DB9 male)----(DB9 female)----------------------(DB9 male)
TXD 2 -------------------------- 2 ------------------------ 2 -----------------------------2 RXD
RXD 3 -------------------------- 3 ------------------------ 3 -----------------------------3 TXD
GND 5 -------------------------- 5 ------------------------ 5 -----------------------------5 GND
DSR 4 -------------------------- 4 ------------------------- 4 ----------------------------4 DTR
DTR 6 -------------------------- 6 ------------------------- 6 ----------------------------6 DSR
CTS 7 -------------------------- 7 -------------------------- 7 ----------------------------7 RTS
RTS 8 -------------------------- 8 -------------------------- 8 ----------------------------8 CTS
NC 1 -------------------------- 1 -------------------------- 1 ----------------------------1
NC 9 -------------------------- 9 -------------------------- 9 ----------------------------9
Note: The indicator DB9 female’s pin4 and pin6 is shor ted, pin7 and pin8 is shor ted!
7.2 When P3 is set to 5:
7.2.1) The baud rate and data format is fixed as per P4 and P5 setting. Responses to serial commands will be
immediate, or within one weight measure cycle of the scale. One second should be more than adequate
for use as a time-out value by remote (controlling) device.
7.2.2) The length of the weight field will be 7 digit weight data, one for minus sign, one for decimal point, two for
measure unit (e.g. “lb”, “kg”). If the unit is lb:oz, another two for “lb” and one for a space (<sp>) after
lb. Units of measure abbreviations are always lower case.
7.2.3) If the weight is overcapacity, the scale will return nine ‘^’ characters (the field of minus sign, decimal point,
weight data is filled by ‘^’).
If the weight is under capacity, it will return nine ‘_’ characters (the field of minus sign, decimal point, and
weight data is filled by ‘_’).
