I Safety Instructions

1

Before using the scale, carefully read, understand, and follow the “Safety Instructions” described in this manual. Observe the

advice given in the “Directions for Use” section to ensure proper operation. Keep this operation manual handy for ref-

erence.

To prevent injury

1) DO NOT SHOCK LOAD the scale, Never step on or sit on the scale. Not only will the scale be damaged, but you may

also be injured.

2) DO NOT APPLY DIRECT WATER SPRAY to the scale if it is powered by an AC adaptor!! You could receive a shock. The

scale is not washdown unless the AC jack is plugged with a water-tight seal.

4) Do not operate the scale if there is smoke or a burnt smell coming from the scale. Remove the batteries or unplug the

AC adaptor immediately. After making sure that there is no danger, consult your dealer. Never try to repair the scale

by yourself.

5) This scale is not an explosion-proof model. Do not use the scale in an atmosphere containing ammable gases or

explosive fumes. A re or an explosion can result.

6) Place the item to be weighed in the center of the platform. Items placed on the edge of the platform may fall off and

cause injury.

7) When weighing a heavy, large or unbalanced item, make sure the item is stable on the platform, otherwise an accident

may occur.

8) When carrying or moving the scale, be sure to hold it by the bottom of the weighing platform with both hands. If you hold

it by the column, the column may become detached causing the scale to fall. This will damage the scale and could cause

injury.

9) Do not insert your nger into the gap or holes in the scale. You may be injured.

10) The DP-6200 uses a liquid crystal display. If the LCD breaks and the liquid leaks from the LCD, do not touch it with your

ngers. The liquid is toxic if ingested. Be especially careful around small children.

To prevent damage to the scale

1) Do not push the indicator or keys with sharp objects. They may break or puncture the switch membrane panel.

2) Use the specied power supply and choose a suitable environment. If you do not, the weight readings may be inaccurate

and the scale may be damaged.

3) The scale is a sensitive weighing instrument, avoid physical shocks. If you drop something on the scale, overload the

scale, step on the platform, or drop the scale, the scale may be damaged and lose accuracy.

4) If the scale becomes dirty, wipe it with a soft cloth. For stubborn stains, apply a little neutral detergent and then wipe the

scale with a dry cloth. Do not use thinner, benzene, hot water, or chemical agents, all of which can cause deformation, dis-

coloration, or deterioration of the scale.

5) Never remove the case. The ne adjustment section may be damaged and you may be injured by sharp edges on the

internal parts.

6) Do not place the scale upside down.

7) When the low battery indicator appears, replace all six of the batteries. When installing the batteries, install them accord-

ing to the polarity markings in the case (+, -). If the scale will not be used for a long period, remove the batteries.

8) Never connect or disconnect the RS-232 cable while the DP-6200 and a connected computer are on. The DP-6200 and/or

the computer may be damaged. RS-232 ports are not hot-swappable.

To keep the scale working efciently

1) Place the scale on a at stable surface that will support the scale and the load.

2) Do not place the scale in an area exposed to direct sunlight or to wind currents from an air conditioner, otherwise, the mea-

surements will not be accurate.

3) Do not place the scale near machines that create vibrations or electromagnetic disturbance, such as microwave ovens,

portable phones, or large motors. This will affect the accuracy.

4) The operating temperature range is from –5°C to +35°C (23°F to 95°F). Do not subject the scale to sudden temperature

changes; allow the scale to adjust to the new temperature before use.

5) If the scale is sealed, do not break the seal. If you break the seal, the scale will not be considered legal for trade. In this

case, contact your dealer.

6) Do not disassemble or modify the scale, you will void the warranty. Modied scales will not be legal for trade.

DP-6200 Technical Manual

The DP-6200 can be setup to be calibrated with pound weights or with kilogram weights. Check

the setting of system parameter 78 (see section IV - Changing the Scale Setup). 000 sets the scale

to be calibrated with kilogram weights, 001 sets the 60 lb and 300 lb scales to be calibrated with

pound weights, and 002 sets the 150 lb scale to be calibrated with pound weights.

1) Open the indicator housing by pulling the release tab forward and

swinging the front panel of the housing forward. Short the two test

pins to the right of the CPU on the main board. The Test Mode

ennunciator and internal counts will display.

2) Press and hold the

IV Changing the Scale Setup

Changing Parameters

The scale setup is controlled by three groups of parameters that determine how the scale operates.

These three groups are User Parameters, System Parameters and Factory Parameters.

User Parameters (00 - 09) can be changed in both User Mode and System Mode. They are easily

accessed, without breaking the seal or opening the indicator housing, and control functions such as

the auto-off, RS-232 communications and whether the scale starts in metric or standard units. The

User Parameters are included in System Mode for the convenience of the technician.

System Parameters (30 - 40) can be changed in System Mode. They control functions that the

technician may need to change under unusual circumstances. Since these functions can alter the

accuracy of the scale, the seal has to be broken to access System Mode through Test Mode.

Factory Parameters (51 - 99) can be change in Factory Mode. They control functions that directly

relate to the accuracy, capacity and divisions of the scale and are rarely changed outside of the

factory. Factory Parameters are usually only changed if a different standard mode (pound, ounce or

pound-ounce) is needed or if a different capacity load cell is installed. Since these functions can al-

ter the accuracy of the scale, the seal has to be broken to access Factory Mode through Test Mode.

Each parameter has two components, the parameter keyword and

the parameter value. The rst two digits are the keyword and de-

termine which parameter is being changed. The last three digits

are the value and determine what the selected parameter is being

changed to.

While each mode is accessed differently, all modes use the same keys to select and change the

parameter settings.

To select the desired keyword, use the keys as follows:



- increase the keyword by one



+





- decrease the keyword by one

To change a parameter value, use the keys as follows:

�

- increase the value by one



- decrease the value by one

�

- decrease the value by ten

To save the last value changed it is necessary to advance to the next keyword before exiting the

setup mode. Press and hold the



key and press the





key to exit System Mode or Fac-

tory Mode and return to Test Mode. Press the



key to exit any setup or test mode.
