Calibration Functions on Verified Balances/Scales
Select the appropriate menu code to define the access status for each of
the following calibration functions, which are activated by holding down the tare
control for a few seconds:
– External calibration C-E
– Internal calibration C-I
– Sensitivity test C-t
External Calibration
Use the access switch to block or release the external calibration function.

Accessible right
Access denied * left
On verified precision balances of accuracy class K, the “external calibration”
function is blocked by the access switch (adjusted to the left and secured against
alteration of the switch setting) after verification.
Quick CAL Using f
You can select the “internal calibration” function at any time by a touch of the f
key (factory setting: accessible). That’s why we call it “Quick CAL” for short.
On AC balances, you can also set a different menu code to change the function
of the f key from “internal calibration” to “sensitivity test.”
