OCS-XZ-GSE/GSC series electronic crane scale combines reliable, advanced electrical hardware
with good software. Using AT-89 series micro-processor and high speed, high precision A/D
conversion technology, the GSE series of scale has a specially designed jittering compensation
circuitry so they can reach steady state quickly with strong anti-interference capability. This
series of scales can be used for weighing application in commercial trade, mines, storage and
transportations.

1. ［ON］: With the main switch on the back of the scale is at ON position, press this key to
turn on the scale.
2. ［RST］: Regardless the status of the scale, press this key for reset operation (applicable to
the scale with LED display).
3. ［OFF］: Under weighing condition, when this key is pressed to display “OFF”. Press it
again to turn off the power. The scale enters Stand-by mode.Press the main switch on the
back to completely cut off the power.
4. ［ ］ : Press this key to change between Measured Division and Selectable Division.
5. ［ ］: Press this key to set the current display to zero. Under weighing mode of

General Scale Operation
1. Turn On the Scale
a) Open the back cover of the scale casing (see Figure 3).
b) Install 4 AA batteries and set the sliding switch to “B” position. In case the scale is
with rechargeable lithium battery (purchased option), set the sliding switch to “A”
position.
c) Close the back cover.
d) Press the mechanical switch located on the back of scale. Then press ON key to turn on
the scale. The scale’s maximum weighing capacity is first shown, and then the scale
Page 5
goes through a self-check sequence.
e) After 0.0 is displayed and zeroing indicator (for GSE model) or symbol (for GSC model)
is lit, the scale is ready for weighing operation. (Note: it is recommended to allow
scale 3~5 minutes of warm-up time before starting weighing operation).
2. Zeroing
a) In general, the scale shows “0.0kg” or “0.00kg” after it is turned on. In case the
display is showing numerical value other than “0”, press “Net” to set the display to “0”.
b) For GSC series crane scale, when “Aut” is set to “0” in the sub-menu, the backlighting
is turned on after “Net” key is pressed and hold for more than 3 seconds. Press and
hold “Net” key for another 3 seconds, the backlighting is turned off. If “Aut” in the
sub-menu is set to “1”, the backlighting is turn on automatically when there is load
added to the scale and off after the weight being removed.
3. Weight Measurement
a) Once the load is suspended completely, the display shows the weight value of the load.
When the “Stable” indicator is lit, weight value can be recorded.
b) In case there is tare such as cable, load the tare and press “Net” to zero the display to
“0”kg. The weight value after this will be the net weight. This will not change until
the tare change or the scale being turned off.
4. Turn Off the Scale
a) After weighing operation, the scale should be turned off. Press the Off key twice to
turn off the display.
b) Press the mechanical switch on the back of the scale case to shut off the power to the
scale completely to prevent the leakage of the battery.
Battery Charging Method
1. Lithium Battery (self contained)
a) Open the scale back cover (see Figure 3) to connect the charger adaptor. And then
connect the power for the adaptor.
b) When the lithium battery is fully charged, the indicator on the charger adaptor is
changed from color red (during the charging process) to green, indicating the
completion of the charge process.
c) For optimized charging efficiency, it is recommended that the charging to be done with
the scale turned Off. According to the lab testing results, with a fully charged
7.4V/2AH lithium battery, GSE series scale can operate over 20 hours and GSC series
scale 40 hours (without backlighting).
d) For optimal battery life time, it is recommended to charge the battery for every 12-hour
of scale operation.
2. Nickel – H Battery
a) Insert the rechargeable batteries into the charger. Connect the power to the charger and
following the instruction of the Nickel-H battery charger.

2. Customer can select either the 7.4V/2AH high power lithium rechargeable battery with
DC8.4V/500mA charger or the 4 Nickel-H rechargeable battery/charger packages. Please do
not use the rechargeable battery package other than those provided by fty. The use of third
party product may void any fty guarantee.
3. For weighing operation, please load the scale with weight load exceeding the scale’s
maximum capacity.
4. Perform routine inspection and maintenance to ensure operation safety for these basic items:
a) Check for loose bolts.
b) Check hook and shackle for deformation, wearing and tearing.
c) Check other scale component for signs of metal fatigue.
d) Check for missing hook latch.
e) Avoid hitting, bumping the display window.
f) Do not use the scale in the rain or heavily polluted environment.
g) Please remove the AA battery when scale is not used for extended period of time.
For problem “a” through “d”, please stop using the scale and send it back to authorized Blue
Arrow dealer or Blue Arrow for repair or replacement of problem parts.
