8-5. Calibration Test Using An External Weight
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)
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 25.
If you use the target weight value stored in
the balance, go to step 5.
Step 4 Specify the target weight value as follows:
SAMPLE
key... To switch the display condition to: "All of the
segments blinking" (target weight selection
mode) or "The last two digits blinking" (value
adjustment mode).
RE-ZERO
key . To select the target weight or adjust the value.
In the value adjustment mode, -15 digits
appear after +15 digits.
key...... To store the new weight value. Even if the 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
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
key. The balance measures the
target weight and 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.
Step 8 The balance displays
glp
and outputs "calibration
test report" using the RS-232C interface or stores the
calibration test data in memory. Refer to "11-2 GLP
Report" of the function table for details.
Step 9 The balance will automatically return to the weighing mode.
