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.
