4. Allgoods weighed should be placed in the centre of the weighpan for accurate weighing.

The overall dimensions of the goods being weighed should not exceed the dimension of the

weighpan.

5. Once the scale has been powered on, it will go throughanLCD display testand it is ready

for use when the displayshows zero.

6. The scale requires 15~20 minutes to warm up before operation to ensure the bestaccuracy.

Caution Corrosion

Due to the storage battery adoptthe advanced free-maintaining technique, customers need not

to replenishelectrolyte.

The scale should be recharged every 3 months to prevent failure of the internal rechargeable

battery.

1. The batteryshould be charged for 8~10 hours.

2. The temperature of batteryshould below 45℃.

Maintaining

1. Please do not discharge with over-current when using the battery. Please charge the battery

after discharging current.

2. Please take down the battery when the scale is not used for a long time or break the

connection of cathode.

3. Do not short the battery terminals to check whether there is current. Please check whether

the connection point is firm to guarantee good connection.

4. The battery should be replaced by specialized person. No reverse-battery or the product

will be damaged.

a) Anode of battery should be connected withAnode of product battery（usually red

cable）

b) Cathode of batteryshould be connected withCathode of product battery (usually brown

cable or black cable)

c) See the picture following

Safety warnings

1. The electrolyte of battery is caustic whichcauses metal, cotton, etc to corrode.

2. The hydrogen will be resolved when using or charging the batteryand it will cause explosion

1-3 Keypad Function

ON/ZERO

KEY

When the power is off, press

ON/ZERO

keyto switch the indicatoron.

When the power is on, press

ON/ZERO

key to return to zero.

Zero Range for non-approval models is ±2% Full Scale.

OFF

KEY

Press the

OFF

key to switch the indicator off.

TARE/PT

KEY: Tare / Pre-tare key

To TARE:

Place the container onto the scale, wait until the weight value is stable, press TARE

/PT

key for zero return and the NETindicationis shown on the display.

Place the object onto the container and the displayshows the net weight value of the

object.

Remove both object and container, and negative value of the container will show on the

display.

Press TARE

/PT again

to clear “tare value”. The scale returns to zero and NET indication

goes off.

TARE function canremain effective untiltare value=full load capacity

Continuous Tare Press TARE

/PT key

for continuous weight increase/decrease on

platter.

Pre-tare cannot be done in tare function. However, if a pre-tare had been preset, and

the tare weight is more than that pre-tare weight, then the Tare can be done.

No Tare canbe done under gross weight display mode.

To PRE-TARE:

Press TARE / PT key, use keypad to input pre-tare weight. When the cursor flashes on

the rightmost digit, press TARE / PT key again to complete.

Pre-tare mode, keypad functionas followed:

MC => upward key(0~9 digit entry) NET/GROSS => move cursor leftward

UNIT => downward key(0~9 digitentry) TARE/PT => move cursor rightward

NET/GROSS

KEY

In the Tare mode, the screen displays the “

TARE

” icon; press the

NET/GROSS

key to switch

between the “Net value” and the “Gross value”.

When the ”GROSS” arrow



shows up, the Gross Weightin the screen = Tare weight +

Net weight, meanwhile, only

NET/GROSS

key is available.

M+

KEY

Sum-up function.

This keyis a composite key, while the item total is shownand weightreturns to net zero,

press M+ key to erase memory.

Whena is new weight added onplatter, the sum-up function can be effective. If this

weight had not been removed, no new item can be added.

Displaywill show the item total for one second, and show the net weight for one second,

then the scale returns to the current weight, and printout the last total.

To clear the Sum-up info, press M+ key to bring up the item total show up, thenpress

M+again, to clear the Sum-up value data.

P.s. To execute the clear function, the weight must return to zero.

KEY

Memoryclear for accumulationdata.

Simple Counting Mode

Use UNIT key to switch unit to Pcs, to enter simple counting mode.

1. Use

NET/GROSS

keyto select a sample number from “10 , 20, 50, 100, or 200”. Display

NET/GROSS key.

2. Select a sampling number, and put appropriate weight onplatter, and press

UNIT key.

Display will show “ ”. The scale will enter counting mode after weight is stable,

and displaywill show the sample number.

Unit weight insufficient ( ) : Sample unit weight < 0.2d (d=division)

Samples insufficient ( ) : total sample < 20d (d=division)

While sampling, if there is insufficient sample or unit weight insufficient indication “”, the

scale is still usable,but there maybe slight inaccuracy.

After Power-off, the scale automatically memorizes the sampling number, and it is available

when “Pcs” unit is selected next time.

If the setting is “automatic average unit weight “, if the object on platter > the previous

sampling number more than 5 pcs, and also < less than100% the previous sampling

number, the scale will execute unit weight calibrationautomatically.
