15 Miscellaneous Information
15.1 Extract from the Preliminary Certificate
• The preliminary test establishes whether the component conforms to the
requirements of the type approval. It can be submitted for calibration in
conjunction with a pre-tested measuring apparatus in a measuring
system set up according to weights and measures legal requirements
and operated by a weights and measures authority.
• The figure (number of disturbance pulses) found in the test step "Testing
the pulse input" (test step no. 2) is only used for testing the function of the
pulse monitoring circuit. The setting of the number of permissible
disturbance pulses which is dependent on the meter and pulse
transmitter must be determined before calibration according to W & M
instruction 5 (EA 5) and saved in system parameter 3.3.1.3.
The number of permissible disturbance/error pulses can be determined
from the meter nominal values based on the following formula:
where:
P
dper
= max. permissible number of disturbance/error pulses
P
pul
= number of pulses per unit volume (meter name-plate)
V
min
= lowest measurement/discharge amount (meter name-plate)
The lowest measured volume must not be less than 200 liters.
Parameter settings for a minimum measurement volume of V

= 200 l
