protection devic e (RCD, GF CI etc .).
IF IN DOUBT SEEK ADVICE FROM A QUALIFIED
ELECTRICIAN.
To avoid the pos sibility of electric shock or damage to the mac hine,
always isolate from the mai ns power supply before carryi ng out any
routine maintenance.
Cleaning the scale
Harsh abrasiv es, solvents, scouring cleane rs and alkaline cleaning
solutions, should not be used especially on the display windows.
Under no circumstances should you attempt to wip e t he i ns i de of t he
machine.
The outside of the machine may be wiped down with a clean cloth
moistened with water contai ning a small am ount of liquid soap.

140 Indicator Operation Manual
Thank you for purchasing the 140 indicator. Please read all operating
instructions carefully before use and keep the following points in mind:
* Avoid lengthy exposure to extreme heat or cold, your scale works best when
operated at normal room temperature. Always allow the scale to acclimate to a
normal room temperature before use
* Allow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible, to give the internal components a chance to stabilize before weighing.
* These electronic scales are precision instruments. Do not operate near an in-use
cell phone, radio, computer or other electronic device. These devices emit RF and
can cause unstable scale readings. If your scale ever performs poorly, try moving
the scale to a different room or location.
* Avoid using in condition of heavy vibration and airflow.
* Read the weight reading in short time after loading. The output signature of load
cell and A/D may be little influenced after weighing for a long time.

Note: The weighing units that can be used are restricted by display
division, and calibration weight unit (restricted by P8, P9, and P10):
For example, if the calibration unit is “kg”; calibration display resolution
is 50kg (that means: P8=5, P9=0, P10=0), and users press UNIT key to
choose weighing units. Lb or lb:oz are not allowed to choose, since the
display resolution of 100lb or 2000oz is not available to this indicator.

3. The 140 indicator will display “CAP.--”, that means the following data is the
full capacity according to your setting of display resolution (P7), display
division value (P8) , location of decimal point-dot in calibration unit (P9) and
capacity’s unit in calibration (P10). If the setting of FS is more than 199999
(regardless of decimal point and weight unit), the FS capacity will be shown
by first four digits and last four digits: “Hxxx” and “Lxxx”.
For example, the display resolution is selected to 100000(P7=31), the display
division is selected to 5(P8=2), the position of decimal point is selected to
one point after zero (P9=1). The calibration unit is chosen as lb (P10=1), so
the full capacity 50000.0lb will be shown as H 50 and L000.0 in lb unit. Also,
in other modes, the data will be shown as “Hxxx” and “Lxxx” when current
display data is larger than 199999 kg/lb (not include decimal point).
Press TARE to go to next step directly; press ON/OFF/ZERO to exit the
calibration mode; or after a few seconds, it will automatically to next step.
4. The scale will automatically display the setting of division. Firstly it will
display “d.--”, and then the data according to your setting of P8, P9 and P10.
You may choose division among these as below:
Ta bl e1 :
0.0001kg/lb 0.0002kg/lb 0.0005kg/lb
0.001kg/lb 0.002kg/lb 0.005 kg/lb
0.01kg/lb 0.02 kg/lb 0.05 kg/lb
0.1kg/lb 0.2 kg/lb 0.5 kg/lb
1kg/lb 2 kg/lb 5 kg/lb
10kg/lb 20 kg/lb 50 kg/lb
Press TARE to go to next step directly; press ON/OFF/ZERO to exit the
calibration mode; or after a few seconds, it will automatically to next step.
5. When ‘CAL.P0’ is displayed, that means the scale will begin to calibrate
scale’s zero-point. Move away any weight on the scale. Press TARE button
to confirm, or press ON/OFF/ZERO to exit this mode.
6. When ‘CAL.P1’ is displayed, the scale will be calibrated on second
calibration point. The default standard weight is 50%FS, and at the same, you
