9.6 Regulatory Mode Functions
The function of the front panel TARE and ZERO keys depends on the value specified for the REGULAT parameter
on the FEATURE menu. Table 9-4 describes the function of these keys for the NTEP, CANADA, OIML, and
NONE regulatory modes.
TARE and ZERO key functions are configurable when the REGULAT mode is set to
INDUST (see Table 9-5 on page 64).

Important
If using a regulatory mode, it is the installers responsibility to make sure that the maximum allowable
number of divisions is not exceeded by primary, secondary or tertiary units of measure (see Section 3.4.1
on page 18).
In this situation, the installer must reduce the number of divisions (also reducing the maximum displayed
capacity of the indicator) of the broader unit of measure to make sure that both units are less than the
allowed maximum per regulatory accreditation.
Table 9-5 lists the subparameters available when configuring a scale using INDUST mode. The table includes the
default values of the INDUST subparameters and the effective (not configurable) values used by the NTEP,
CANADA, OIML, and NONE regulatory modes.
