is error; adjust potentiometer’s position to make the ADC data will be positive
value and larger than (Zp%+ Zk%) x NFS. Normally the indicator is
factory-calibrated, and end users do not need this operation.
Below is the drawing of position of the zero-point potentiometer on PCB for
conference, decrease ADC data by rotating clockwise, and increase ADC data by
rotating counter-clockwise.
3. Press UNIT key to select displaying weight inner code or input the inner working
voltage value. When the “U x.xx” is displayed, the display digit is voltage value,
and the unit is V. The proper working power voltage is between 5V and 8V.
4. Press TARE key to display filtered or un-filtered weight A/D data; when X is on,
the data is filtered.
5. Press ON/OFF/ZERO key to exit this mode and return to normal weighing
mode.
========================================================
Ⅴ. WORKING PARAMETER SETUP:
1. When scale is in normal weighing mode, press and hold down ON/OFF/ZERO
and UNIT key until ‘SEtUP’ is shown, that means the scale is in SETUP mode.
2. This indictor has 19 kinds of parameters to be selected and setup by this function.
3. During SETUP mode, press UNIT key to change the flashed digits, and
11
HOLD/PRINT key to shift the flashed position. Press TARE key to confirm and
save the set data and enter next setting. Press ON/OFF/ZERO key to exit this
mode.
4. Display
1) P A.B : Item A parameters and one digit can be input.
2) P A.BC: Item A parameters and two digits can be input
3) P AB.C : Item AB parameters and one digit can be input
4) P AB.CD : Item AB parameters and two digits can be input
5. Detailed setup:
5.1) P1.xy: Auto-off time xy= 00-15
00: means no auto-off function
01-15: means the scale turns off to save power after 01-15 minutes when
no variety of weight on scale and no key operation.
5.2) P2.x: HOLD/PRINT key function definition
x=0 means only HOLD function
x=1 means only PRINT function
x=2 means HOLD and PRINT function: short-time click the
button once for Print function, and hold the button for
several seconds for HOLD function
5.3) P3.xy: Hold function setting
Xy=0: No hold function;
Xy=1: When the scale becomes stable, it will hold the larger weight
reading;
Xy=2: When the scale becomes stable, it will automatically display and
hold the weight reading. When this weight is below 10d, HOLD function
will automatically inactivated. When the new weight is more than 10d, the
scale will hold the new weight when stable.
Xy=3-50: When the weight variety is within the setting range +3~50d, the
weight reading will remain unchangeable.
5.4) P4.x: RS232 mode setting
x=0: No RS232 function. It will not transmit or receive any data although
the scale is with RS232 hardware. RS232 function can be only activated
when scale is in normal weighing mode.
x=1:Press PRINT/HOLD key, the scale will output the current stable
