KWS 152 weighing scale
Thank you for purchasing a KPC-2000 or a KWS 152 scale. Please read all operating instructions
carefully before using and note the following points:
•
Avoid lengthy exposure to extreme heat or cold as your scale works best when operated at normal
room temperature. Always allow the scale to acclimate to a normal room temperature before use.
•
Allow suf cient warm up time. Turn the scale on and wait a few minutes to allow the internal
components to stabilize before calibrating or weighing.
•
The cleaner the environment the better. Dust, dirt, moisture, vibration, air currents and proximity
to other electronic equipment can all cause an adverse effect on the reliability and accuracy of
your scale. Only use on a stable, vibration free surface.
•
Handle with care. Gently apply all items to be weighed onto the tray top. Although this scale is
designed to be quite durable, try to avoid rough treatment as this may permanently damage the
internal sensor.
•
Place the item to be weighed on the platform and after the stable weight is displayed, remove the
item immediately. This will aid in the longevity and accuracy of this weighing instrument.
•
Do not operate near an in-use cell phone, radio, computer or other electronic device as these
devices emit RF and maybe cause unstable scale readings.
•
Adjust the feet on the bottom of the scale to level it.
•
The scale may be powered by an AC adapter or a 6-volt rechargeable battery. When “Lo.bAt” is
displayed alternatively, this indicates that the battery is low. Please recharge battery immediately.

Power supply:
12Vdc, 600mA AC adapter, with positive center or 6V4AH rechargeable battery.
Note:
. When the rechargeable battery is fully recharged, the scale
can work for 20 hours continuously.
. When the power supply is lower than 5.4V(
+
0.1V), the scale
will be turned off automatically .
. When the power supply is lower than 5.7V(
+
0.1V) but over
5.4V(
+
0.1V), the scale will alternatively display ‘Lo.bAT” and the
other current display.

Key function
1.
ZERO /ON/OFF:
1.1 When scale is off, press this button to turn the scale ON. The scale will enter self-examination, show the working
voltage “x.x Udc”, display full capacity “F3.000kg”, “F6.000kg” or “F15.000kg”. The scale will get proper power-on-zero-
point and display zero reading. (Note: the proper (power-on-zero-point range is: (calibration zero-point)
+
20% FS)
1.2 When the scale is on, press this key for less than 5 seconds, and ZERO key function will activate; press this
button for more than 5 seconds, and ON/OFF key function will activate:
ZERO:
ZERO key range is (power-on zero-point)
+
5% FS. ZERO function can only be activated when the scale is in
stable weighing mode and the activation of the ZERO key will also clear the recorded tare weight. The ZERO LED light
will be on, NET LED will be off. ZERO function will be not activated when the current weight is not in the range of (power-
on zero-point)
+
5% FS, and it will display “0------” or “0_____”, then will go back to previous weight reading.
ON/OFF:
By pressing this key for more than 5 seconds, the scale will display OFF, and turn off after releasing the key.
2.
TARE /UNIT
Press this button for less than 5 seconds, the TARE key function will activate. Press this button for more than 5 seconds,
UNIT key function will activate:
TARE:
TARE range for this scale is up to 102%FS. This function should be operated when the scale is in stable mode.
When the TARE function is active, the “NET” LED will be on. [Note: (Gross weight = Net weight + Tare weight ≤102%
FS)
UNIT:
To change the weight unit, hold the TARE/UNIT button for more than 5 seconds or until your desired weight unit
appears.
•
Calibration
Calibration requires technical knowledge and standard test weights. Calibration should only be performed by a scale technician.
Check your local phone book for your nearest scale repair center. If the she scale technician does not have the Kilotech calibration
procedure and access codes, this can be obtained by calling the Kilotech Service Center at 877-328-5988 (USA) or 800-694-4445
(Canada).
•
AUTO-OFF function
When the scale is ON, simultaneously press and hold down TARE and ZERO buttons for more than 5 seconds till the
“A.oFF.x” is displayed (x=0,1…9: means when the scale has no weight changing and no key pressed for 1…9 minutes, the
scale will auto power off to save battery power, when x=0, means that the auto-power off function is disabled). Press the
TARE button to choose the auto-off time and press ZERO button to con rm and save the setting.
•
Some display symbol meaning:
0
------
:
Power-on zero-point is over (calibration zero-point) +20%FS) when scale is turned on, or the reading weight is over (power-
on zero-point) +5%FS when pressing ZERO button;
0______:
Power-on zero-point is below (calibration zero-point) -20%FS) when scale is turned on, or the reading weight is + (power-on
zero-point) -5%FS when pressing ZERO button;
_______:
the current weight is less than –25% FS;
_______:
the current weight is over 102% FS;
CAL-0:
Zero point at calibration;
CAL-F:
Full capacity at calibration;
CAL-Er:
Calibration error;
A.ch.E r:
analog channel error;
EEP. Er:
EEPROM accessing error or data in EEPROM is error or not in their normal range;
Lo.bAt:
The voltage of internal working is below 5.7V(
+
0.1V)
x.x Udc:
The voltage of internal working is x.xV(
+
0.1V)
