2.0 OPERATION
2.1 SAFETY INSTRUCTIONS
Read this manual carefully before you operate the Crane Scale.
•Unpack the Crane Scale carefully from the packing using suitable
lifting equipment as the weight of the Scale can be over the limit
for manual handling, particularly for the higher capacity model.
•Attach it to your Hoist or equivalent existing equipment securely in
the upright position. Make sure that the equipment to which the
scale is attached is in proper condition. The operator should be
trained for safe operation. It is recommended to fasten the hook
on the ground level and then to lift the scale to the desired height
rather than lifting the scale to the fastening hook.
•Do regular visual inspection for any damage or wearing out of
parts. Particularly the split pins at the end and the inner wall of the
hook and all joints should be checked regularly. If any damage or
wearing out has taken place, replace the parts at the earliest.
•Do all inspection and maintenance work when the scale is not in
use.
•Do not expose the scale to extreme temperatures. The operating
temperature range is 0°C to 40°C.
•Secure the sample to be weighed in the hook of the scale. Ensure
that the sprung Safety Lever returns to its resting position which
prevents the sample from slipping out of the hook.
•Do not exceed the maximum capacity of the Scale as mentioned
in section 1.2.
•Clean and protect your scale after use.

2.2 BATTERY OPERATION
When battery goes low, the reading will keep on flickering. It is the time
to charge the battery with the special charger. If the scale is being used
without proper charging, the display will flicker and after 30 minutes the
display will show “     
          
     ”. If you still don’t charge the battery, the scale
would be shut down automatically after 5 seconds of warning, in order to
protect the battery. Charge the battery immediately.
If you do not use the crane scale for a long time, you may need to
charge the battery every three months.
2.3 CHARGING BATTERY
Use the special charger to charge battery, using other type of charger
may cause harm to the battery.
Please ensure your AC power meets the required rating of power.
The LED on charger will turn on when battery is being charged and it will
be flickering when battery is fully charged.
After the full charging, the AC adapter will automatically switch over to
the low current charge process, so that it is not necessary to disconnect
the AC adapter immediately.
2.4 BASIC OPERATIONS
Power on and off- Press [ON/OFF] key to on and off the scale.
Zero the scale- When there is no item on the scale but the reading is not
zero, press the [ZERO] key to re-zero the reading.
Reading lock- When reading is not stable, you can use the [LOCK] key
to lock the reading, so that you can read easily. After you finish reading,
press [LOCK] again to return to normal weighing mode.
Change division- You can use the [CHANGE] key to change division, All
scales have been set for the middle division in the factory.
Overload Warning- Please do not add any item that exceeds the
maximum capacity of the scale. When the display shows

2.5 AUTO SLEEP
The crane scales have automatic sleep function. You can disable this
function, see section 4.0. When the scale weighs a sample below the
minimum capacity (20d) for more than the set time, it will automatically
enter the sleep mode. Only the last point will turn on at LED. Once you
press any key or add more weight on the hook, it will return to normal
weighing mode again. Please pull out the antenna before operating the
remote controller.
2.6 REMOTE CONTROLLER
The crane scales are supplied with remote control. You will find 4 keys
on the remote controller.
Key A: use as [ZERO] key
Key B: use as [CHANGE] key
Key C: use as [LOCK] key
3.0 CALIBRATION
Turn off the power if you are using the scale.
Then turn on the power, press [ZERO] and [CHANGE] key at the
same time during self-checking.
Display shows “”, asking for entering the password.
Input password, use [LOCK] key to move the active digit,
[CHANGE] key to increment a digit. Press the [ZERO] key to
confirm the password. The default password is “”.
Display will show “”, press [CHANGE] key until display shows
“”.
Press [ZERO] key to enter calibration, display shows “”.
Empty the hook, after STABLE indicator on, press [ZERO] key to
confirm, after few seconds, zero calibration is now complete.
After zero calibration, display shows a value of mass for span
calibration. You can change this weight by using the [LOCK] key
to move the active digit and [CHANGE] key to increment a digit.
After entering the value of the calibration mass, press the [ZERO]
key to confirm. When display shows “”, add the calibrate mass
on the hook after stable indicator on. Press the [ZERO] key again,
wait for few seconds, span calibration is now complete.
