8-4. Calibration Using an External Weight

This function calibrates the balance using an external weight.

When the MC-10K is used

Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on the weighing pan. Press and hold the CAL key until Calout

0 .000 g

Press and hold

Calout

		is displayed, then release the key.
Step	3 The balance displays				Cal 0	.
		If you want to change			the calibration weight,
		press the			key and go to step 4.
				SAMPLE
		If you use		the calibration weight value stored
		in the balance, go to step 5.
Step	4 Specify the calibration weight value as follows:
			key... To switch between the calibration weight
SAMPLE
			selection mode (All of the digits blinking) or
			the value adjustment mode (The selected
			digits blinking).
			With the MC-10K, the digits in the 1st, 2nd,
			and 3rd decimal places can be adjusted.
			With the MC-31K, the digits in the 1st and
			2nd decimal places can be adjusted.
			key.. To select the calibration weight (All of the
RE-ZERO
			digits blinking) or adjust the value (The
			selected digits blinking). Refer to page 19.

PRINT key...... To store the new weight value. Even if the

	AC adapter is removed, the data is
	maintained in non-volatile memory.
	key ......... To cancel the operation and return to		.

Step	8	If the "GLP output (info)" parameter, of the function table,
		is set to "1" or "2", the balance displays	glp	and	GLP output	glp
		outputs the "Calibration Report" using the RS-232C
		interface or stores the data in memory. For details on the				end
		calibration report format, refer to "11-2. GLP Report".
Step	9	The balance will automatically return to the weighing mode.				0	.000 g
Step 10		Place the calibration weight on the pan and confirm that the value

displayed is within ±20 digits of the specified value. If it is not within the range, check the ambient conditions such as breeze and vibration also check the weighing pan. Then, repeat steps 1 to 10.
