Nova-Tech PGL Series - Manual (Page 23)

7) Place the mass on the balance. Press [Enter] to continue
8) On the PGL 203 and PGL 303 models the display will show the busy symbol
and after calibration is complete it will show “LOAd 0” on the display.
Remove the weight. The scale will return to weighing.
9) All other models will return to weighing as soon as calibration is complete.
8.2 AUTOMATIC CALIBRATION
The balance will ask for calibration when the balance has automatic calibration
enabled and the conditions of the automatic calibration have been met.
The calibration will be called for if the time since last calibration exceeds a preset
time, typically 4 hours.
The balance will call for calibration to be carried out by flashing the “CAL” symbol
on the display. As soon as the balance is calibrated the symbol will be turned off.
The Auto calibration feature can be enabled, disabled or changed by the user
options to meet the requirements of the users. See section 12.5.
8.3 CALIBRATION ERRORS
Occasionally during calibration an error will be detected. These errors can be
caused by:
z Unstable readings
z Improper calibration weights being used
z Large shifts of zero from the factory settings
When an error is found a displayed message will be shown and the calibration
must be done again. If the balance has error messages more than once it is
possible the mechanics have been damaged.
