Warnings

Avoid using the balance in any harsh environment.

•
Only trained professionals are allowed to do repair work.

•
Turn power off before connecting/disconnecting the power source.

•
Avoid overloading or dropping material onto the platform as that could damage

•
the balance.

Material that has a static charge could influence the performance of the balance.

•
Electromagnetic interference can affect the reading of the balance.

•
Unplug the power before cleaning and use a piece of soft cloth (do not use any

•
aggressive cleaning agent); Make sure no liquid enters the balance.

Preparation

1. Carefully remove contents from the package which may include fragile parts.

2. Carefully assemble the scale by placing the scale pan.

3. Place the scale in a firm and flat surface, and avoid location where the scale

maybe subject to vibration, sunlight, airflow, contact with water, and strong
electromagnetic wave.

4. Level the scale by using the bubble level indicator (if available) and adjusting the

feet of the scale.

5. Locate scale in the following condition:

1. Temperature : 0oC ~ 40oC

6. Plug in the scale to a surge protected power outlet if using the AC adapter. You

may use the internal rechargeable batteries also once it has charged.

7. Press the ON/OFF key in the front panel to turn the scale on and wait for it to

finish initialization (i.e. when the display shows a weight of 0).

8. Let the scale warm up for 1 minute before calibration and use.

9. Make sure any weight placed on the scale is not beyond the rated maximum.

10.If scale is not used for an extended period of time, turn off the scale and unplug

the AC adapter (if it’s connected).

Si.CAL-01 Menu

This setting enables user to make a linear calibration.

Calibration can be done with 2 steps up to 10 steps maximum.
Take the Earth Gravity into consideration. The gravity parameters can be
programmed from the setting menu “G1set” and “G2set” (explained later in the
document)

For example, we will calibrate the scale in 3 steps: 0kg, 0.5kg, and 1kg.
When the pan is empty press “Enter” key.

The screen will the blinking while measuring zero.
“Si-01” is shown to indicate that the measure of zero has been taken and that the
unit is ready to take another measurement.

The FILTER menu must NOT be modified.

OIML Menu

This setting has two values:
0: Scale does NOT follow OIML recommendations
1: Scale does follow OIML recommendations

There are 3 sub-parameters:
RS: Manual zero limit - Adjusts 0-99% from the bottom of the scale; It’s the capacity
for zero-ing when pressing the Zero key
OR: Initial auto zero limit - Adjusts 0-99% from the bottom of the scale; It’s the
capacity for zero-ing when turning on the scale
OT: Zero tracking limit - Adjust 0-99% of the division [e]; Adjusts automatically of
zero drifting

Here is an example

Press “Enter” key

The above mode indicators the scale does not follow the OIML recommendations
and the sub-parameters RS, OR and/or OT can be programmed.

Press “Enter” key

With this configuration of the RS sub-parameter, the scale is capable of absorbing the
zero deviation (2% from the bottom of the scale). For example, if the bottom of the
scale is 5.000 kg, the scale will absorb up to 0.100 kg b pressing the “Zero” key.

Press “Enter” key.

!18/25

! OP-W Series

! User Manual / Scale Settings

With this configuration of the OR sub-parameter, the scale is capable of staring with
an initial deviation of the load cell by 16% from the bottom of the scale.

Press “Enter” key.

With this configuration of the OT sub-parameter, the scale can absorb the zero
drifting which are inferior or equal to 40% of the division value.

For example, if the scale is configured for the division of 0.001 kg = 1 g, 0.4 g zero
deviations will be absorbed.

Press “Enter” key.

To exit and save the configuration, select “Quit” menu and press “Enter” key.

Troubleshooting

Q: The scale is not showing an accurate reading.
A: Make sure the scale is placed on a firm and flat surface and that there are no
external interference. Please revisit the “Preparation” section of this manual. Also,
please make sure the calibration procedure has been performed correctly. It won’t
hurt to run through the calibration process again when in doubt!!!!
