8.5.Calibration Using an External Weight

This function calibrates the balance using an external weight.

1Connect the AC adapter and warm up the balance for at least one hour with nothing on the weighing pan.

2	Press and hold the					key until		Calout	is
			CAL
	displayed, then release the key.
3	The balance displays
				Cal		0	.

If you want to change the calibration mass, press the RANGE key and proceed to step 4.

If you use the calibration mass value stored in the balance, proceed to step 5.

4Specify the calibration mass value as follows: RANGE key........ The key to switch blinking figures.

RE-ZERO(+)key ... The keys to select the calibration mass or

	(-)key		adjust the mass value. Refer to page 23.
MODE	(-)key		adjust the mass value. Refer to page 23.
		key.......... The key to store the new mass value. Even
PRINT		key.......... The key to store the new mass value. Even
			if the AC adapter is removed, the data is
			maintained in non-volatile memory.

CAL key............. The key to cancel the operation and return

to Cal 0 .

5Confirm that there is nothing on the pan and press the PRINT key. The balance measures the zero point.

Do not allow vibration or drafts to affect the balance. The balance displays the calibration mass value.

Example:

New weight 100.0012 g

6 Place the displayed calibration weight on the pan and press	Place weight

. Remove the weight from the pan.

8	If the "GLP output (info)" the function table is set, the
	balance displays glp and outputs or stores "Calibration
	Report". Refer to "11.2. GLP Report" for details.
9	Remove
9	The balance will automatically return to the weighing mode.
10	Place the calibration weight on the pan and confirm that the
	value displayed is correct. If it is not within the range, check GLP output
	the ambient conditions such as breeze and vibration also
	check the weighing pan. Then, repeat steps 1 to 10.
