CALIBRATION MODE
In order to maintain normal operation, the SL-W-CR requires a direct line of sight with the wireless crane. SellEton Scales weighing modules utilizes radio frequency to communicate between the wireless display and load cell. This means the display and crane scale must be on the same frequency. Please read [Chapter IV about Special Function] for reference of wireless communication channel and address settings. Prior to calibrating your indicator, it is necessary to carefully check if the radio frequency among each unit is the same. If so, power on the wireless crane scale and the wireless SL-W-CR display indicator. This will allow the user to operate the calibration sequence after the unit does a self-inspection (count down) and to receives the weighing data mode.
PARAMETER SETTING
WEIGHT CALIBRATION
COMPENSATION CALIBRATION
MODIFICATION OF STANDARDIZED RATE AND CALIBRATION PASSWORD
Note: the standardized rate r2 cannot be allowed to modify randomly otherwise the result of weighing process may be not accurate. Also, it is better not to change calibration password M1.
SPECIAL FUNCTION
DISPLAY OF WIRELESS CHANNEL AND ADDRESS
When switching on the power supply, the display shows software version number
[H2.01], after 1 second, it displays wireless communication channel [C xx],
and then shows the address [nxxxx]. After that will go into self-inspection
mode (count-down sequence).
SEARCH OF WIRELESS CHANNEL
When the SL-W-CR hand-held wireless indicator is in a self-inspection program
(count down sequence), press 8 and DEBUG, the indicator will search for
weighing module radion frequency channel automatically. When it has
successfully found the weighing module adio frequency channel, it will display
[ok]. Important reminder: please remember the radio frequency channel which be
displayed in the weighing module channel.
MODIFICATION OF WIRELESS CHANNEL AND ADDRESS
-
Modification of hand-held wireless indicator:
When the SL-W-CR hand-held wireless indicator is in self-inspection (count down sequence), press 7 and ZERO to display the indicator’s communication channel, you can press numerical buttons to change the channel number (00-31) and then press ENTER to display address. Also you can press numerical buttons to change the channel number. After press ENTER to finish. -
Modification of hand-held wireless indicator and weighing module:
While the SL-W-CR hand-held wireless indicator in the self-inspection, press 9 and ENTER to display a black screen. Enter the password 0147888888 and ENTER to display channel number. After you can press numerical buttons to change channel number (00-31) and then press ENTER to show address. Also the numerical buttons can be used to change and press ENTER to finish.
WORKING MODE
While the SL-W-CR hand-held wireless indicator in the self-inspection (count
down mode), press DEBUG and then input [666666], press ENTER to display [F x],
then press 1 to select host and press 0 to select auxiliary and then press
ENTER. When displaying [U x], press 1, the weighing module is DC3.6V power
supply; press 0, the weighing module is DC6V power supply, then press ENTER.

In displaying weight status, press T to store the instant displayed weight as
tare weight and to show net weight.
INSTANT CUMULATIVE WEIGHT
In displaying weight status, press ENTER to accumulate instant displayed
weight and show the cumulative number and back to displayed weight status
after 1 second. Each weight will accumulate one time and only if the displayed
weight back to 0 and reweighs, it will implement new instant cumulative
weight.
DISPLAY CUMULATIVE WEIGHT
In displaying weight, press A to separately display lowest 4 bits (L) and
highest 4 bits (H) of displayed weight and then back to displayed weight
status.
CLEAR CUMULATIVE WEIGHT
In displaying weight, press C and then ENTER to clear weight and back to
displayed weight status; or only press C to back to displayed weight status if
remaining cumulative weight.
DISPLAY SCREEN BACKLIGHT
In displaying weight, press B to adjust light of display screen backlight.
BATTERY VOLTAGE OF SCALE
In displaying weight, press V to display battery voltage of scale.
MATTER NEED ATTENTION
- If wireless communication is not running normally, please check carefully the reliability of power supply and antenna connection. Also check the consistency of hand-held wireless indicator’s and weighing module’s wireless channel and address.
- This indicator should away from the place that has corrosive gas and liquid, conductive powder, moist environment and violent vibration.
- Prohibit using strong solvent (e.g. benzene, Nitro oil) to wash the cover.
- The hand-held wireless indicator has a built-in 3.6V battery and it uses a 4.2V charger to recharge. The main board adopts 6V battery to supply power and uses 7.5V charger to recharge. Please remember to charge the battery immediately if the no energy or it will damage the battery. Also because of the self-discharge by battery, please charge the battery which not use frequently once two weeks. The battery is consumable product which does not belong to warranty scope.
- Please immediately to cut off the power if the display runs into a malfunction and then send back to the company for repairing. Please non-professionals do not self-repair.
