10.3.4 PCAL: Calibration of the Built-in Weight (UW series only)
Not applicable to a verified balance as a legal measuring instrument in the EU
PCAL is used to calibrate the built-in weight to a standard calibration weight that is correctly adjusted,
traceable and/or certified. The PCAL procedure is password protected. The administrator should set
this password (refer to 10.3.5).
1 Unload the sample from the pan and verify a
zero mass display.
2 Select the menu item .
“PAS: 0000” is displayed.
3 Enter the PCAL password using the [UNIT] and
[PRINT] keys, then press the [O/T] key.
The default password is 9999, set at shipment or
upon menu reset.
After “PCAL 3” is displayed, the value of the stan-
dard weight to be loaded blinks.
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.
Caution
Use a correctly controlled, precise calibration weight for this procedure. If it
is performed without a correct calibration weight, span calibration and cali-
bration checks using the built-in mass may not be correct in subsequent
operations.

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
7.4 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 “3. Specifications” for calibration range. Attempt of
inputting an invalid calibration weight value causes an error message.
