II Configuration, Installation and Application

The wireless electronic crane scale is mainly composed of scale body and indicator, accessories

like charger, cable, are also supplied.

1. Configuration of the scale body

This part is makes up of weighing load cell, carrier and transmitting mechanism, case, A/D

module, wireless digital transmitter, battery, etc.

3. Wireless working mode:

Usually, XK3190-H2B Indicator is used in wireless transmitting electronic crane scale. Install

the transmitting antenna before operation, and then open the small cover on the scale body to

install the battery, after inserting battery plug into the battery socket and turning on the switch, the

Scoreboard Interface Calibration Switch

annunciator begin to twinkle, indicating the electric circuitry of the scale body in working state.

The crane scale will go into the power-saving mode and twinkle once every 5 seconds when it has

been out of operation or the weight on the scale has kept unchanged for 30 seconds. At this time,
the scale will go into the normal working condition automatically if the load varies≥0.1%F.S and

0.3%F.S. within one second. The scale will be powered off automatically if the load weight keeps

unchanged for 30 minutes. If need to be restarted, turn the power switch off or take off the battery

plug, and then turn power switch on or insert plug several seconds later,

Note: No keeping battery in scale for a long time without antenna installed, just in case that

damages happen to wireless digital transmitter in scale body.

4. Wire Working Style

No necessary to install battery and antenna to XK3190-H2B during indicator wire working

mode. Weighing operation can be performed after connecting scale body and indicator to the 2

ends of signal cable and turning on the switch. When powered off, press <<Off>> to shut down

the indicator first and then cut off the back power switch or take off the wire transmitting cable.

The indicator will remain supplying power to scale body and shorten the life of the battery if the

back power switch is not off or the cable is not took off.

5. Replacing the printing paper and the ink ribbon of the micro printer

Open the printer cover, press the pothooks on the both sides of printer rack to take the printer

off, take out the paper reel (paper is used up) and put a new reel of paper in, cut the paper end into

an arch and then push it into the paper feeding slot of the printer, press <<Paper>> to set it into an

appropriate position, and close the printer cover.

The ink ribbon needs to be replaced when the printed letter became vague. Open the cover of

the printer and press the button marked with <<PUSH>> on the ink ribbon, one end of the ribbon

will be tilted. Take out the old ribbon and install the new ribbon in a reverse direction, then close

the cover.
