ASC ES-H Series Electronic Balances

Product Information

The ES-H series electronic balances are high precision weighing and measuring devices that use loadcell, microcomputer, and a big liquid crystal display screen for accurate and speedy weighing. They are widely used in various industries such as factories, mines, institutions, agriculture, traffic, building, water conservancy, medicine, and food. The balance is equipped with simple operation features, accuracy, stability, and more. It is particularly useful for weighing precious products in business.

Construction and Installation

The package includes an electronic balance with a division of 0.01g or higher, an AC adapter, an operation instruction manual, one weight, and a wind cover.

Operation Instructions

• Turn On
  To turn on the balance, insert the round plug of the AC adapter into the square hole at the back of the balance. Then insert the AC adapter into an alternating outlet with two holes or install 8 alkaline batteries AA SIZE in the battery holder at the bottom of the balance (pay attention to the Plus(+) and minus(-) ends). With no load on the platform, press the power button. All the segments of the display will be shown, then the software version is displayed. When 0 is displayed, weighing can be done.

• Turn Off
  To turn off the balance, press the off button while the balance is at work.

• Weighing Method
  Press TARE to set the display to zero. Put the object to be weighed on the platform. Wait until the unit g appears and the reading is stable, then the weight can be read.

• Balance Calibration
  When performing precision weighing, calibrate the balance as follows:

• Sensitivity Calibration
  When calibrating the balance sensitivity, two different weight values can be used. According to the shown calibrating weight value, press MODE, the two calibrating weight values can be interchangeable, press TARE to make sure. After that, the balance will display 0. In a few seconds, the balance will display the calibrating weight value. At this time, put the corresponding calibrating weight on the center of the platform according to the shown weight value. In a few seconds, the display will stop, and meanwhile, the calibrating weight value will be shown, indicating that calibration is over. Normal weighing can be done.

Care and Maintenance

To keep the balance operating properly, the housing and platform should be kept clean and free from foreign material. If necessary, a cloth dampened with a mild detergent may be used. Keep calibration masses in a safe dry place. Unplug the AC Adapter when not in use. For long term storage, remove the batteries.

Error Codes

There are no specific error codes mentioned in the user manual.

Description

ES-H series electronic balances do weighing and measuring with high precision loadcell, microcomputer and big liquid crystal display screen. It has the advantage of simple operation, speedy weighing, accuracy, stability, and so on. It is widely used in factories, mines, institutions, agricultures, traffic, building, water conservancy, medicine, food, and so on. It’s more applicable in business for weighing precious products.

Packing list

1. Electronic balance 1 pc.
2. AC adapter 1 pc.
3. Operation Instruction 1 copy
4. Balance (Its division is 0.01g or higher) with one weight and a wind cover.

Operation

Turn on

• Put the round plug of AC adapter into the square hole at the back of the balance, then put AC adapter into an alternating outlet with two holes. Or install 8 alkaline batteries AA SIZE in the battery holder at the bottom of the balance (pay attention to the Plus(+) and minus(-) ends).
• With no load on the platform, press . All the segments of the display will be shown, then the software version is displayed. When “0” is displayed, weighing can be done.

Turn off
To turn off the balance, press while the balance is at work.

Weighing method

• Press  to set the display to zero. Put the object to be weighted on the platform.
• Wait until the unit “g” appears and the reading is stable, then the weight can be read.

Balance calibration

• When precision weighing is done, calibrate the balance as follows:
• First take away the object from the platform, then press  to set the display to zero.
• Press , displaying “SCALE” or “LINE”. “SCALE” means calibrating the balance sensitivity; “LINE” means calibrating the balance linear.
• Press to make sure (If press , the two kinds of calibration can be interchangeable.)

1. Sensitivity calibration
   • When calibrating the balance sensitivity, two different weight values can be used.
   • According to the shown calibrating weight value, press , the two calibrating weight values can be interchangeable, press  to make sure. After that, the balance will display “0″. In a few seconds, the balance will display the calibrating weight value. At this time, put the corresponding calibrating weight on the center of the platform according to the shown weight value.
   • In a few seconds, the display will stop, and meanwhile the calibrating weight value will be shown, indicating that calibration is over. Normal weighing can be done.
2. Linear calibration
   • Being in the state of “LINE”, press , the balance will display “0”. In a few seconds, the balance will display 1/2 weight value of full capacity; according to the shown weight value, put the corresponding calibrating weight on the center of the platform.
   • In a few seconds, the balance will display the full capacity weight value, according to the shown weight value, put the corresponding calibrating weight on the center of the platform. In a few seconds, the display will stop, and meanwhile the calibrating weight value will be shown, indicating that calibration is over. Normal weighing can be done.

NOTE: The balance linear has been calibrated in the factory, unless the users need to change the loadcell or have the right weight.

NOTE: Two kinds of weight value in the table can be used as the selected calibrating weight value when calibration is done.

Counting Function

The balance will count parts based on the weight of a reference sample: 5, 10, 20, 30, 40, or 50 parts. To get more accurate counting result, the weight of the parts should be equal, meaning the less the error of the single part is , the better.

1. Press , the balance will display “pc CON”.

2. Place a container on the platform, then press  the balance displays “pc ADD 5” which is the preset reference quantity. “5” shows the quantity of the reference sample.

3. To change the reference quantity, press , repeatedly until the desired quantity is displayed. Press  to make sure the quantity of the reference sample.
   NOTE: If you want to restart parts counting, repeat the operation steps above. If “PC Err” is displayed, it means the sample is too light to provide accurate results within the error range set by the balance.

4. Add parts to the container as desired and read the quantity on the display. At this time, only “pc” counting signal is displayed (“g” is not displayed.).

5. Press  UNIT to switch between parts counting and weight.

Unit Selection
This balance has the function to select these units: g, oz, ozt, dwt, lb, ct. Press  to switch.

Percentage Setting Function
Put the object on the platform, when the reading is stable, press and hold until the symbol % is displaying, then release it, indicating that setting is over.

Backlight Function
Press  MODE to turn the backlight on or off.

Care and maintenance

• To keep the balance operating properly, the housing and platform should be kept clean and free from foreign material. If necessary, a cloth dampened with a mild detergent may be used. Keep calibration masses in a safe dry place.
• Unplug the AC Adapter when not in use. For long term storage, remove the batteries.

Error Codes

The following list describes the various errors which may appear on the display and the suggested remedy. Display description

• Err 0: With the platform on, this signal indicates the platform is too light. Make it heavier properly. If this error still occurs, the sensor or the circuit board may be destroyed. The balance must be sent to the manufacturer to be serviced.
• Err 1: The sample being weighed exceeds the capacity of the balance. If the error occurs when the sample is within the balance capacity, maybe the balance is not correctly calibrated.
