I. Notes
1.) Please do not get the balance wet. If the balance gets wet,
please wipe it with a dry cloth. If water damage occurs, this will

II. General Information
i.
Overview
This balance is very accurate balance, which is designed to
meet the needs of laboratories, industry and commercial users.
This balance has a very clear and big display which greatly
reduces the chances of mistakes. The high - speed processor
1
processes the weight very quickly and will provide you with a
very speedy weighing experience. The glass windshield
protects against wind (PMW only). The integrated RS232
enables you to auto send the weighing data to PC or other
equipment if you have the required softwar e.
In order to provide a quick and easy weighing experience,
the following functio ns ar e included.
1. Kinds of different internati onal weighing units: g, ct , oz,
ozt, dwt, gn, lb, kg, t, tola, gsm, TAR, TMR, tlt, tlh, etc.
2. Wide range of function: weighing, parts counting, check
weighing, anim al weighing, percent weighing, ac cumulating
function, etc.
3. Large LCD disp lay with backlight.

III. Instructions for Use
i.
Precautions Befor e use
1.) The balance must be used on a stable, flat, and vibration
free surface in order to achieve accurate measurements.
2.) Please use an inde pendent power outlet to av oid
interference by ot her ele ct r onic appliances.
3.) In order to bring the ba lance into a horizontal position,
the adjustable feet can be turned either clockw ise or counter-
clockwise until the air bubble is in the center of the marked circle.

Storage and shipping c ondition
Allowable storage h umidity: 50%~75%R H
temperature: 10*~30* ( fluctuations*1*/h )
After unpacking the balance, please chec k it im m ediately for
any visible damages as a result of r ough handling during shipment
iii.
Getting Started
1)
Please check whether t he components listed bel ow on
the balance are in good condition:
4
*
Glass windshield (PMW only)
*
Weighing pan
*
AC adapter
*
Calibration weight
2)
Installation instructions
*
Place the weighing pan on the balance.
*
Leveling the balance using the leveling feet so that t he air
bubble is centered wit hi n t he circle of the level indicator.
*
Plug the cord on the AC adapter into the AC jack; then plug
the AC adaptor into a wall outlet. Please make sure that the
voltage rating printed on the balance is identical to your local line
voltage.
IV. Calibration
For maximum accuracy, calibration is requir ed before use.
Indicators your scale m ay need to be calibrated:
*
Firstly use this balance.
*
Weighing for a long ti me ( about after 30 days).
*
The ambient conditi on changed.
*
The temperature ch anged strongly.
Instructions for extramural calibration
1.) First remove all obj ects from weighing tray
2.) Press CAL until the scale show "CAL", calibration will
begin.
3.) The scale will show t he r equired weight for calibration.
5
Place the required weight as indicated on the screen on the center
4.) Once the required weight is placed on the scale it will
show lines across the screen -------, Then it will show the required
weight once more.
5.) Then remove the weight and the screen will show ------
then set back to zero. Cal ibrat i on is complete.
Note: Please make sure you are using the proper weighing
mode when calibrating.
Instruction for Linear calibration (Do not atte mpt t his
operation unless y ou have a full set of test weights, not just
the supplied calibrat i on w eights).
Note! Errors in linear it y
calibration are NOT c overed by warranty .
Please only enter Linear calibration when the precision is
different on different weights.
for example: 3200g/ 0. 01g
1.) First remove all obj ects from weighing tray .
2.) Press CAL until the Zero balance shows
"CAL".
3.) Then press MODE until the balance shows "CAL" once
more. Intramural calibration will begin.
4.) The balance will show "3000.00g". Place 3000g of
weight on the center of the weighing pan. Then the balance will
show lines across the screen -------, wait until it shows
"3000.00g" once more. Then remove the weight and the scree n
will show ------.
5.) The scale will show "2000.00g". Place 2000g weight on
the center of the weighing pan. Then the balance will show
lines across the screen -------, wait until it shows "2000.00g"
again.Then remove the weight and the screen will show------.
Then set back to zero. Ca libration is complete.
