KEYPAD FUNCTIONS
1. [HOLD]: Press this key to keep the current weight and there
is a LED indicaon lamp on the boom of the display window.
Press this key again when the displaying weight flickers to
cancel the HOLD funcon.
2. [UNITS] : Press this key to change units between Ib and kg.
3. [ZERO] : Press this key to set the current weight to zero.
SCALE OPERATIONS
1. Turn on the Scale
Press the power switch located under the displaying window
of scale. The scale's maximum weighing capacity is first shown,
and then the scale goes through a self-check sequence.
Aer 0.0 is displayed and the stable light is on, the scale is ready
to weigh. (Note: it is recommended to allow the scale 3~5 minutes
of warm-up me before starng the weighing operaon).
2. Zeroing
In default, the scale shows“Okg" or“0.0kg”aer it is turned
on. In case the display is showing numerical value other than
“0", press [ZERO] on the keypad or the remote to set the
display to“0".
3. Weight Measurement
a) Once the load is on the scale completely, the display shows
the weight value of the load. When the“Stable" indicator is on,
weight value can be recorded.
b) In case there is tare such as cable, load the tare and press
[ZERO] to zero the display to“0"kg. The weight value aer
this will be the net weight. This will not change unl the tare
change or the scale being turned off.
4. Turn Off the Scale
Aer weighing operaon, press the power switch to shut off
the power completely to prevent the leakage of the baery.
5. Unit Conversion
Under the weighing mode, press key to change units
between Ib and kg.

The scale will record the new calibraon data.
Enter into seng state, and make sure the
scale is with non-load.
It will display “00000” aer 5 seconds.
Load the scale. The closer to full capacity the
beer. For example, 1500kg
CARE AND MAINTENANCE
1. For weighing operaon, don't load the scale with weight load exceeding the maximum capacity.
2. Perform roune inspecon and maintenance to ensure operaon safety for these basic items:
a) Check for loose bolts.
b) Check hook and shackle for deformaon, wearing and tearing.
c) Check other scale component for signs of metal fague.
d) Check for missing hook latch.
3. Do not touch the display screen directly.
4. Do not use the scale in the rain or in a polluted environment.
5. Remove the baery and store the scale in a dry place if the scale is not going to be used for some me.
The scale uses maintenance-free 6V/4.5AH Lead-Acid baery. When scale is with low power, it will display the
following signals:
a. When the low power indicator light is on. The scale needs to be charged now. However, the scale can connue to be
operated for about 3 hours without charging.
b. Aer the low power indicator is ON for several hours without charging or there is no more power in the baery, the
crane scale will be powered off automacally. It will take about 5 hours to fully charge the baery.
C. Aer baery charging, if there is no display, it indicates that either there is difficulty in baery charging or a
damaged baery.
With a fully charged baery, the scale can be operated for about 30 hours. To prolong the baery life, recharge the
baery promptly for every 20 hours of usage. When charging the baery, use the original charger supplied with the scale
to prevent the baery from unnecessary damages. In addion, turn off the power to shorten the recharging me. WHEN
recharging the baery, the recharging light will be red. When the light is green, it indicates the baery is charged fully.

ERROR INFORMATION
Err0: The calibraon data should not less than 4 digits. Or the data will be invalid.
Err1: The calibraon data should not exceed the data 65536.
Er2; There is incorrect password to modify the calibraon data.
Err3: The weight value at the calibraon point is too small. It should be no less than 3 valid digits.
Err4: Incorrect calibraon password. Please input the correct password.
Err5: The internal code at the calibraon point is too small. The valid internal code is from 3000 to 65536.
Fault analysis by checking the internal code
Press [Zero] to power on the scale, it will first show“Ad". Then unpress the key, it will show the internal code. If there is no
load on the scale, the internal code should be between 6000 and 8000. If the internal code is not in the range from 6000 to
8000, please send the scale back to your supplier for repair.
