3 Provides access to everything in level 2 plus access to configure the
meter.
4 Provides access to everything in level 3 plus access to transfer new
firmware to the meter.
5 Provides access to everything in level 4 plus access to calibrate the
meter, reset registers and change certain security setting.
7.6.2.1 Limitation of total access attempts
The meter limits the total number of access attempts to six when incorrect passwords are entered. At the
seventh attempt, the meter blocks access whether the password is correct or not. The block is in effect until the
next hour shift. After that, new password attempts may be made.
7.6.2.2 Passwords
A password consists of up to 12 case insensitive alpha-numerical characters. The authorisation check may be
deactivated for a level by deleting the password. When connecting to the meter, access is granted to the highest
level that is lacking password regardless of the password given by the user.
If the setting ‘Require COP password compliance (min length 6)’ is activated, a new password is required to be
at least 6 characters. The setting can only be changed at access level 5.
7.6.2.3 Security settings
The following security settings modify what can be configured at what access level. The settings are of the type
active/not active, and can only be changed at access level 5.
 Permit measuring configuration only at level 5 If this setting is active, settings in the
measurement form can only be changed at
access level 5.
 Block configuration of transformer compensation If this setting is active, transformer compensation
cannot be changed at all.
 Block configuration of display sequence 4 If this setting is active, it is not possible to change
the content of display sequence 4, or change its
name or activation.
7.6.2.4 Access restriction for measurement configuration
Generally the meter allows to be reconfigured at access level 3. This function requires level 5 for measuring
configuration.
7.7 Loggers
The Prometer 100 has two identical, parallel and individually configurable loggers. That which is described in
this section applies both to logger 1 and logger 2.
7.7.1 Overview
A logger in a Prometer 100 can log values for instant quantities, energy registers and external registers. Some
quantities can be logged both by phase and as total values for all three phases, others only as total values. The
table provides an overview of quantities that can be logged. Certain instant values in the table are not available
in 2-element meters and thus cannot be logged; see the section Instant values (pg. 37). Logger Parameters can
be read as profile data and SIP wise.
