8.5 Overview of Calibration, and Adjustment
During calibration, a calibration weight is used to determine how much the
displayed value deviates from the actual value. This deviation is compared
against a preset target value. The subsequent adjustment eliminates this
deviation.
Calibration and adjustment must be performed regularly:
−
Daily, every time the device is switched on
−
After every leveling
− After changing the ambient conditions (temperature, humidity, or air
pressure)
−
After setting the device up at a new installation site
Calibration and adjustment may be performed in different ways:
−
Adjusting with the isoCAL function
−
Internal or external calibration or adjustment
Only internal calibration | adjustment is possible for all conformity-assessed
devices in legal metrology.
8.6 Adjusting with the isoCAL Function
The device can be automatically internally calibrated and adjusted using the
isoCAL function.
Requirements
−
The device is
not
located in the menu.
−
Alphanumeric inputs are
not
active.
−
The load on the weighing pan remains unchanged for 2 minutes.
−
The load on the weighing pan amounts to no more than 2% of the maxi-
mum load.
−
The device does
not
register an input for 2 minutes.
If all requirements for starting the isoCAL function are met and one of the
following conditions occurs: The isoCAL function is automatically triggered.
Possible conditions are:
−
The ambient temperature has changed since the last
adjustment | calibration.
− The interval time was exceeded (interval time, see Chapter “15.8
Recommended Calibration Weight”, page 72).
−
The device has been leveled.
−
The device has been disconnected from the power supply since the last
adjustment | calibration (only for conformity-assessed models).
