PCAL: Calibration of the Built-in Weight (UPX Series only)
Not applicable to a verified balance as a legal measuring instrument in using region
PCAL is used to calibrate the built-in weight to a standard calibration weight that is correctly calibrated,
traceable and/or certified. The administrator should set this password (refer to
7.3.5
).
Notes
If this built-in weight calibration is executed when no accurate standard
weight is available, span calibration and calibration checks using the built-in
weight will not be able to be carried out accurately. Always use a correctly
calibrated, accurate standard weight to carry out built-in weight calibration.
1
Unload the sample from the pan and verify a zero mass display.
2
Select the menu item
10
[PAS:0000 ] is displayed.
3
Enter the PCAL password using the [UNIT] and
[PRINT] keys, then press the [O/T] key.
After “PCAL 3” is displayed, the value of the
standard weight to be loaded blinks.
Changing the Calibration Weight to be Used
Pressing the [CAL] key allows changes to the weight
value. Modify the value using the [UNIT] key and [PRINT]
key, then press the [O/T] key. Refer to
4.4
for how to
make numerical input. To interrupt modification, press
the [POWER] key. Calibration range with external weights
is designated to each model. Refer to
“1. Specifications”
for calibration range. Attempt of inputting an invalid
calibration weight value causes an error message.
4
Load the standard weight displayed, and press the
[O/T] key.
Soon, zero is displayed and blinks.
5
Unload the weight and press the [O/T] key.
The display proceeds to “PCAL 0”. When the mass
display appears, calibration is complete.
