SAFETY RECOMMENDATIONS
Before using the crane scale, please, read this manual carefully and
follow the instructions.
• DON´T overload the crane scale, this could seriously damage the
loadcell (repair not covered by the warranty).
• DON´T leave any weight on the hook for a long time, this reduces the
accuracy of the equipment and shorts the life of the loadcell.
• Before using the scale, check rings, hooks and other parts, cotter pin,
if the screw is loose and deformation loose every 3 months.
• Charge the battery when the display shows the low power indicator.
• DON’T use the crane scale in rain or storms.
• After used, hook should vertical suspended or the loadcell could be
damaged.

USE OF CRANE SCALE
Turn ON
Press the key on the crane, the scale begin the self test, at the same
time, auto-zero initialization, then the display will show power status “Pbt85”
(85% power) and finally the crane scale enters to weighing mode.
Turn OFF
Press the key for 3 seconds or Dand Btogether on remote control, the
display will show “PA80” (80% power), 1.5 seconds later, the display will
show “off” and scale power off.
Tare / Zero
To obtain the net weight of a product. Place a container and press the
key or Bon remote control, the display shows zero value, put the product into
the container, the display will show the net weight of the product.
Display brightness
1. With the crane scale disconnected, press the key the same time
press also the key .
2. The display will show: “Dsp X”.
3. Available options:
X=0 Low brightness.
X=1 High brightness.
X=2 Automatical brightness (when weight changes, the high

8
brightness is activated, after 20 seconds of stability, the low
brightness is activated).
4. Press key to select the desired mode.
5. Press the key to return to normal weighing mode.
Hold function
1. Press the key Don remote control, the display´s reading will remain
locked for 30 seconds.
2. Press again the key Don remote control, the Hold function will be turn
off, the balance will return to normal weighing mode.
Weighing accumulation function
When the weight is stable, press the Ckey on the remote control to accumulate
the display values and view the accumulation times “n32”, 2 seconds later,
back to normal weighing mode.
To cancel accumulation function, press the Bkey on remote control and
returns to normal weighing mode.
ON / OFF Save power
Press the Akey on remote control for 2 seconds, the display will power off,

CALIBRATION
Calibration using the remote controller
1. Power on the crane scale and keep pressed the Dkey until display shows
“CAL SP”.
2. The display will show “CAL 00”, press A key once to display “CAL00”.
3. Do not hang on the hook any goods at this time.
4. Display will show “LOAD”, press the Akey until view “-------“ and then
later on display “LOAD”.
5. Press the Dkey to input the calibration weight value (long press Dkey to
increase the number of digit, click to the left shift).
6. Lifting weights, until steady 4 to 5 seconds.
7. Press the Akey to show “--------“, 2 seconds after the display of the
hanging weight values, calibration is finished, put weight down, turn it off.
Calibration using keys of crane scale
1. When power on and self detecting, keep pressed key until display
shows “CAL SP”.
2. Press the key once the display shows “CAL00”.
3. Do not hang on the hook any goods at this moment.
4. Press the key once the display shows “--------“, after few seconds,
the display will read “LOAD”.

5. Press the key to input the weighing value of the calibration weight
(keeping pressed the key means adding number, single clicking
means left shift).
6. Hang the calibration weight and wait for 4 – 5 seconds until the stable
sign light on.
7. Press the key once the display shows “-----------“, few seconds
after, the display will show the weight calibration value. Calibration is
over by now. Put down the weights and power off the scale.
PARAMETERS SETTING
Parameters setting using the remote controller
