This function tests the weighing accuracy using an external
weight and outputs the result. This is available only when
the "GLP output (info)" parameter is set to "1" or "2".
(Calibration test does not perform calibration)
When the MC-10K is used
Step 1 Connect the AC adapter and warm up the balance
for at least 30 minutes with nothing on the weighing
pan.
Step 2 Press and hold the CAL key until CCout is
displayed, then release the key.
Step 3 The balance displays CC 0 .
If you want to change the target weight, press
the SAMPLE key and go to step 4.
A list of usable weights is shown on page 19.
If you use the target weight value stored in
the balance, go to step 5.

RE-ZERO key
.
To select the target weight (All of the digits
blinking) or adjust the value (The selected

AC adapter is removed, the data is
maintained in non-volatile memory.
CAL key
.........
To cancel the operation and return to CC 0 .
Step 5 Confirm that there is nothing on the pan and press the PRINT
key. The balance measures the zero point and displays the
measured value. Do not allow vibration or drafts to affect the
balance. The balance displays the target weight value.
Step 6 Place the displayed target weight on the pan and press the

displays the measured value. Do not allow vibration or
drafts to affect the balance.
Step 7 The balance displays end .
Remove the weight from the pan.
