GOYOJO GY50002 (01) PDF MANUAL

Verify that the AC Adapter input voltage matches the local AC power supply.

Use the scale only in dry locations.

For best results, use the scale in the specified optimum operating temperature.

Use your scale with care, gently loading items to be weighed onto the center of the pan. Avoiding rough treatment will aid in the life of your scale.

It is not suggested to use the balance in environments with excessive moisture (water), strong air currents (wind/air blow), dust, electrical interference, strong magnetic fields, or extreme temperatures.

Power: AC220V~DC 9V

Max power: 5W

Accuracy level: II or III (depending on model)

1. Put the balance on a steady, flat surface away from vibration, direct sunshine, air blow, or strong magnetic disturbance.

2. Adjust the four feet of the balance to make the bubble in the level indicator centered.

3. Plug in the AC adapter.

4. Press the “ON/OFF” button. The display should show “0”, “0.0”, or “0.00”, indicating the scale has entered the weighing state.

If the display does not show the zero symbol (e.g., the digital display shows an arrow that does not point to the zero position), it means the scale has not reached a stable state. In this case, please try moving the balance to a different location that is more stable and free from disturbances.

1. Press the function key TARE to clear the readings to “0.0g”.

2. Remove all loads from the platter. Press and hold the “CAL” button for 3 seconds.

3. Release the button when “–CAL–” is shown on the display.

4. When the display shows a calibration weight value (e.g., “200.00” for GY30001, which corresponds to a 2kg weight), put the specified standard weight on the pan accordingly.

5. When the display shows the weight figure of the standard weight, remove the weight. The calibration is finished.

1. Remove all loads from the platter. Press and hold the “CAL” button for 3 seconds.

2. Release the button when “–CAL–” is shown on the display.

3. When the display shows a calibration weight value (e.g., “200.00”), press and hold the “PCS” button for 3 seconds.

4. Release the button when “–CAL–” is shown on the display again.

5. Put on the standard weight accordingly. Remove the weight when the reading is stable.

6. Put on the standard weight again (this implies subsequent calibration points if applicable, following prompts or procedures for multi-point). Continue until the scale shows “0.0g” to finish the multi-point calibration.

The following table provides calibration weight information for various GY series models:

1. Press the “PCS” button. The display will show “–COU–” and a sample quantity (e.g., “10 pcs”).

2. Place the sample quantity of objects (e.g., 10 pieces) on the pan. The objects must be uniform in size, shape, and weight, with a weight deviation of less than 5% between pieces. Each piece’s weight must be greater than the scale’s minimum division (d).

3. Press the “PCS” button again. Wait for the figure on the display to stabilize. The scale will then start the piece counting mode, displaying the count of items placed on the pan.

4. To exit piece counting mode, press the “PCS” button while in this mode.

1. Ensure the scale’s current unit is “g”. Place the object that will serve as the 100% reference weight on the pan.

2. Press the “UNIT” button repeatedly until the display shows the unit “%”. The scale will enter percentage programming mode, taking the weight on the pan as 100%.

3. Remove the reference object. Place the object you wish to measure on the pan. The display will show its weight as a percentage relative to the reference object.

Press the “UNIT” button to cycle through and select the desired weighing unit available on your scale model.

If the weight of the object on the pan exceeds the maximum capacity of the scale, the display will show “——- g”. You should remove the object from the pan immediately to prevent potential damage to the scale.

1. Press and hold the “PCS” button until the scale skips the piece counting procedure and the display shows “CD–OFF”.

2. Press the “TAR/CAL” button repeatedly until the display shows the baud rate setting menu, for example, “C3- 2”. (The number after C3- indicates the current selection).

3. Press the “PCS” button to cycle through and set the desired Baud Rate Setting (BRS).

Available baud rate options are typically:

C3-2 —- BRS 2400

C3-3 —- BRS 4800

C3-4 —- BRS 9600

C3-5 —- BRS 19600

Select the desired option by pressing “PCS” and then allow the scale to return to normal operation or follow further prompts if any.

1. Press and hold the “PCS” button until the scale skips the piece counting procedure and the display shows “CD–OFF”.

2. Press the “TAR/CAL” button repeatedly until the display shows the print setting menu, for example, “C5- 3”. (The number after C5- indicates the current selection).

3. Press the “PCS” button to cycle through and set the desired print mode.

Available print mode options are typically:

C5-0 —- continuous printing

C5-2 —- key printing (prints when a key is pressed, e.g., PRINT key if available)

C5-3 —- command printing (prints when a command is received, typically when connected to a computer)

Select the desired option by pressing “PCS” and then allow the scale to return to normal operation or follow further prompts if any.

1. Press and hold the “PCS” button until the scale skips the piece counting procedure and the display shows “CD–OFF”.

2. Press the “TAR/CAL” button repeatedly until the display shows the display speed setting menu, for example, “C2- 2”. (The number after C2- indicates the current selection).

3. Press the “PCS” button to adjust the speed.

Note: It is generally not suggested to adjust the display speed privately unless you are familiar with its effects on performance.

To use the density function, you need to acquire a density stand and a below-weighing hook separately.

The general steps are:

1. Fix the density device to the balance.

2. Weigh the object on the scale pan (this is the weight in air).

3. Weigh the object while it is submerged in a liquid medium of known density (e.g., water), using the below-weighing hook.

4. Use these measurements to calculate the density of the object. The manual states “Calculate the density,” which may involve manual calculation or a built-in function depending on the specific model’s capabilities (not detailed further in the provided document).

Note: The “Under line” and “Upper line” descriptions might refer to how segments of dashes appear on the display. If “——- g” appears, it specifically means overload.
