3.2.6. Printing
This balance is configured to transmit weight data to a computer or printer via the RS232 port. To print the
weight data to the RS232 port on the AL-201S, tap the MODE key. For the AL-311, press the PRINT key. You
can also set the balance to continuously send the weight data, without having to press the PRINT key. For
more information on configuring the RS232 output, see section 4.2.
3.2.7. Calibrating The Balance
The balance may need to be calibrated in certain situations such as:
Before weighing for the first time •
After the balance has not been used for some time •
If the balance location has changed •
If ambient temperatures have changed greatly •
1. Prepare the calibration weight (200g for AL-201S and AL-311).
2. Clean the weighing pan and press TARE to re-zero the balance.
3. When the balance is stablized, press and hold the CAL button. “C” should appear on the display. If not, the
balance was not stable, try again.
4. Carefully place the calibration weight onto the weighing pan.
5. The display will show “200.000g / 200.0000g”. Once the “o” symbol at the lower left corner of the display
disappears, the scale will beep once to indicate that calibration is complete.
3.2.8. Linear Calibration (available on model AL-311 only)
Linear calibration adjusts the balance at two or more points, rather than just one. To enter linear calibration,
use configuration code “312”. See Section 4 for information on entering configuration codes.
1. Once the code is entered, you should see “Line on” on the display.
2. The display will then show “Line 0g” to indicate that it is setting the
zero point. Make sure the device is stable and all glass doors are
closed, then press TARE/ZERO.
3. The display will now show “Line 100g”. Place a 100g calibration
weight onto the center of the platform and close the glass doors.
Press TARE / ZERO when you are ready to confirm the weight.
4. The display will now show “Line 200g”. Place a 200g calibration
weight onto the center of the platform and close the glass doors.
Press TARE / ZERO when you are ready to confirm the weight.
5. The display will now show “Line 300g”. Place both the 200g and
100g calibration weight onto the center of the platform and close
the glass doors. Press TARE / ZERO when you are ready to confirm
the weight. The display will show “Line off” then shut off.
