8. [Samp] key: Put enough sample on the platform, then input the sample quantity, it
first displays in unit weight window. Then press this key while the weight display
is stable, the number shifts to number window, the unit weight window displays
the unit weight of the sample. If the unit weight calculated is less than 80% of the
graduation, the “U.W” signal display. If the weight of sample is less than 4 time of
graduation, then the “sample” signal display. If you need to change the quantity
of sample , you should first press the key [Clear], then input the new number.
If you’ve input the number for 3 seconds, then you can input the new number
directly without pressing the key [Clear].When the unit weight is max. four
decimal points, the unit weight value can’t exceed 1 kg. Or there will be calculate
mistake.
9. Backlight On/Off: Press [Zero] key for 3-4 seconds, the backlight will be switched
on or off.
10. Adjust the decimal point number for the unit weight: Enter the unit weight form
the keyboard, when the unit weight is zero, press number key “0” to adjust the
decimal point number for the unit weight.
ALARM INDICATION
1. The weight window displays “-----” with continuously alarm sound when the-
weight over 100%FS+9d, if the ADC overflows, the weight window displays
“—Adc—”with continuously alarm sound. For these instance, the weight
should be taken away.
2. The number window displays “—OF—” when the number or accumulated
number over 99999. The scale will not response if the accumulated times
over 100, but the original accumulated data will be retained.
3. If the voltage of the accumulator is low, the weight window displays “—Lb—”
while the weight is zero (The weight display will recover to normal when it is
loaded ). Under this condition, you can use the scale in a short time, but you
should plug in the AC plug as soon as possible to recharge the accumulator.
4. The weight window displays “HHHH” or “LLLL” when the zero weight is
higher or lower than the permitted range.
5. If the weight window displays “-SYS-”, it means the system parameter is
wrong., you should send it for maintain immediately.
6. If the weight window displays “Err-2” after self-testing, it means unstable
weighing, please see III/1/(2),(3).
WEIGHT CALIBRATION
1. Press [A.C.] key till the weight window display “-CAL.-”, the unit weight window
and the number window display 0 or smaller number
2. Weight calibration:
•
F.S. calibration: Put enough weight on the platform. press [Accu] when display is
stable. The calibration finish.
•
Calibrate by any weight: Press [Tare], then weight window displays “-----“. Unit
weight window and number window don’t change. Input the weight by keyboard,
then put the corresponding weight on the platform. Press [Accu] when display is
stable. The calibration finish.
REGULAR TROUBLESHOOTING
1. Unstable weighing
•
Low voltage for accumulator: Switch off the scale immediately and recharge it
more than 12 hours.
•
Low intensity or strong shake for platform: Strengthen the platform or avoid-
shake.
•
Influenced by the wind: Set a glass cover to reduce the influence of the wind.
2. No display when switch on the scale
•
Accumulator is unusable: Change the accumulator if it remains invalid after
recharging.
•
Broken with fuse or switch: Change the fuse or switch.
•
Others: Send it for maintain.
TRANSPORTATION AND STORAGE
•
Avoid shock and dampness during transportation.
•
Avoid strong sunshine and rain during storage.
ACCESSORIES
•
Instruction Manual
•
Power supply wire
ATTENTION
1. Please read this instruction manual carefully before you use the scale.
2. If it has not be used for long time, please recharge it once 2 months at least, and-
keep the power switch on “off” status to avoid discharge of accumulator.
3. LCD of the scale must to be operated under rich light, you are advised to select
product with backlight under low light condition.
4. Avoid collision when you put the weighting object on the scale.
