Safety guide
Read carefully the following instruction and advice before using this scale.
u Over-loading this scale is harshly prohibited
u Refrain from long-time loading that could lead to excessive fatigue on loadcell used inside
the scale. Excessive fatigue on loadcell would decrease the accuracy and shorten the
life of scale.
u Check the shackle and hook regularly.
u Check the battery power level before/after use and recharge the scale in time.
u In order to maximize the battery life, periodic recharging is necessary for scales even not in
use for long time.
u Do not try to repair the scale by yourselves.
u Use privately attached charger only.
u The scale can show the cell capacity when power on. For example when U 86 is shown,
meaning the current cell capacity is 86%. If the cell capacity is 20%, please charge the
scale as soon as possible to avoid damaging the battery.

Chapter 1. Product Description
C9 digital electronic crane scale is high accuracy, one-side direct display measuring unit which
combines load cell and power supply together. It can be directly hung on the hook of a hoist and
ensure the scale to complete the tasks of loading and weighing goods synchronously. The screen is
made up of super-bright tube (LED), which can be easily seen in 25 meters. The scale body is made
of strong alloy aluminum. The structure is compact and operation is quite easy.
The product is equiped with wireless communication, ranged up to 500m with data
transmission.

2.1 Information on the panel
(1) In the different status, different information is showed. User can operate scale according to the
notes showed on displayer.
(2) The light on upper right to the displayer means the charging of the battery. It’ll be on when
charging the scale.
(3) The light on the left side indicates stable status. When the scale becoming stable during operating,
the light will be on.

1. Tare:
In the normal weighing status, press [Tare] and displays “0”.
2. Tare cancel:
In the status of tare, press [Tare] again to cancel.
3. Accumulation function:
Press [Accu] on the remote controller can accumulate the current weights. After pressing [Accu] it
displays “N—XX”
→
“H XX”
→
“L XXXX” automatically then back to weighing status. “N—
XX” means the times of accumulation, “H XX”+“L XXXX” is total weight of accumulation. (After
pressing [Accu] every time, the value of N will be added 1.)
4. Accumulation clear:
The max time of accumulation is 99, it’ll display N—OF if exceed, please clear the current
accumulation at that time. Press [Zero] during accumulation station, which will be cleared.
5. Zero:
In normal weighing status, press [Zero] to setup “0”.
6. [Func] usage:
Press [Func] can setup parameter, press [Enter] it displays code of parameter.

Chapter 3. Calibration
3.1 Illustration:
When scale is stable, press [Func] and press [Enter], it displays parameter code XX. Press “↑”“↓”
“←”“→” to choose code 09 and press [Enter], which displays “SET” and entering calibration status.
Step 1: Setup parameter (e.g.: Max capacity 5t, standard weights 4t)
After displaying “---SET---”, operate as table 3-1 as followed.
