    3.3 Operation for Tare Subtraction Place the tare (container) on the balance. As you place the tare, the balance indicates its weight.  Reset read-out indication to zero. Press the Zero/Tare key. The tare is subtracted and the  balance indicates zero. Load the sample to be weighed.
  • Page 14 Key Points of the Procedure The following applies equally to all the measurement modes for weight measurement, counting, and percentages. After the balance is switched off, there is still enough current to display [ ]. This indicates that the AC adapter is connected to an electrical outlet, but that the balance is turned off. When the balance is switched on again, [ ] will disappear.

  • Page 20: Counting Pieces

    6. Counting Pieces To implement piece-counting, the specified samples are loaded on the balance, and their average unit weight (hereinafter, simply the “unit weight”) is entered and saved. The procedure for saving unit weights is called sampling. The counting procedure consists of loading articles that have already been sampled on to the balance. The number of pieces is then calculated by dividing the total weight of the loaded articles by the unit weight saved in memory.
  • Page 21 Changing the sampling number, if necessary. If samples to be counted widely deviate in weight, or a higher measure of How to change the value accuracy is desired, it is recommended  that users change the sampling number   to a larger value.

  • Page 23: Measuring Percentage

    7. Measuring Percentage The percentage measurement function operates by weighing an actual sample, selected as the reference, and saving its weight as the reference value and indexing it as 100%. When a measurement sample loaded on the balance is lighter or heavier than the reference, its weight is indicated as a percentage (%) value relative to the reference weight.
  • Page 24 Key Points of the Procedure While samples are being saved, the value indication disappears temporarily, and only the [M] mark flashes. If the balance is affected by wind or other vibrations during this process, the saving time may be prolonged. ...
  • Page 25: Limit Function

    8. Limit Function The limit function judges measurements according to a limit value saved in the balance.  The function shows the judgement result by displaying the [ ] mark as either HI (excessive), OK (appropriate), or LO (insufficient). This function is very useful when discriminating between conforming and nonconforming articles.

  • Page 30: Calibrating The Balance

    9. Calibrating the Balance Since electronic balances are affected by gravity gravitational acceleration, they produce different values in various locations. Therefore, before use, balances must be calibrated at the location where they are installed. Calibration is also required after long periods without use, or if a balance begins to produce inaccurate values.

    9.3 GLP-compliant print At calibration, the AJH-CE Series enables printing in a format compliant with GLP. Set the function to the GLP print support ([   ]) side, then connect the balance to a printer or other equipment. When calibration is complete, the balance prints out the format illustrated below. Since only items are printed, the data should be entered manually by the person who conducted calibration.
