ⅠThe safety guides

Please  before  using  your  Crane  scale,  it  is  careful  to  read  the  following
*Strictly forbid the usage while overloading.
*Long  crane  weight,  will  lower  the  accuracy  of  crane  scale  and  shorten  the
usage life.
*Before using, please check the battery voltage.
*Must often check the safety between hook, ring and conjunction parts.
*Long time do not use, also should periodically maintain the battery.
*Do not try the one open and fix the crane scale.
*Need to be used the specialized power adapter.

Ⅵ Operation method

*Turn on Press【OFF/ON】,display the battery voltage〖U 6.**〗. Display 〖00000〗~〖99999〗-〖0〗kg, to this , can hang the weight.
*Creation zero method

  Operation Display Hint: After open, general
1 Press【TARE】 〖0〗
2 Press【→0←】 〖0〗

Dedut the tare method

Operation Display Hint:Afterhanginguptare,press【TARE】,display〖0〗,
Then hanging the weight, display net
Press【TARE】 〖0〗


*Check battery

Press【OFF】,display 〖U6.**〗

Hint: General, battery should at〖U 6.**〗above.
*Refresh the method
1. Off, the charger line inserts the rear of CRAE SCALE socket inside, the light
on the rear is green, refreshing the beginning, being light change is red,
refresh the be over.
2. Can unload the battery set to refresh alone.
Hint: refresh time generally longer than 8 hours, long hours refresh to can’t
have no damage to the battery.

*The warning of low voltage in battery
When battery voltage lower than〖U 5.80〗,the display appears flicker, but can
still work, after lowest voltage, can ’ t display, Please refresh.

*Overload the warning
When the weight(tare + net weight)exceeds the Max Cap, display〖OVER〗, keep
the instauration normal. For the sake of usage that guarantees the Crane
scale the safety, prohibition exceed to load the work.

*Save the energy function
Static over 15 minutes after, display 〖 - 〗, be the weight after changing,
instauration display actual weight.

*The method of off

Static15minutes,display〖 -〗,static60minutes,off.

Ⅸ Maintain simply

Phenomenon Reason Solution
Do not display Battery set is bad
Battery buttons up loose
Check battery set
Tight afresh
The display gleams The voltage is low Off to Refresh
Can’t off/on 【OFF/ON】key damage Replace the key
Can’t deduct tare 【TARE】key damage Replace the key
The  battery  light  is  not
Power adapter damage
The  power  adapter  did  not  put good
Check power adapter
Check electric outlet
The display is unsteady The loads is unsteady
Load cell exceeds to load

Damp influence in scale
The stability loads
Replace the load cell
Deposit in the dry environment
Empty  scale  the  display is not a “0” After open, use immediately
Scale long time on the ground
Open, still3~5minutes
Hang to deposit
The weight error is big Hang the method wrong The hook must can swing
The battery voltage can’t
go up
The battery is bad
The electric outlet is bad
Replace the battery
Replace the electric outlet
Remote distance id short Receive window too dirty
The remote control battery is bad
Make sweep
Replace the battery

Ⅹ Hint

The battery is bad
The electric outlet is bad
Receive window too dirty
The remote control battery is bad

Replace the battery
Replace the electric outlet
Make sweep
Replace the battery

1. Must use the right usage with maintain the method?
2. If hang the weight changes direction, can’t push directly the Crane scale to revolve.
3. When the outdoors, if meet the thunder and lightning and rain etc. circumstance, must
pause usage.
4. Check each part if crane scale before using, in good condition.
5. When the display battery voltage is low, and the light is red, should check the battery
whether damage, please replace the same specification battery.
6. When do not use, please hang to deposit.
