Title:
ANALOG-INDICATOR-TYPE METER APPARATUS
Document Type and Number:
Japanese Patent JPH0735778
Kind Code:
A
Abstract:

PURPOSE: To provide an analog-indicator-type meter apparatus which can automatically (electrically) adjust indication of an indicator after assembly of the apparatus and can reduce an error in meter indication.

CONSTITUTION: An analog-indicator-type meter apparatus comprises an analog- indicator-type meter body 10 including two electromagnetic coils 11, 12 placed perpendicularly, a permanent magnet 14 attached to a rotation axis 13 provided perpendicularly to the above coils and an indicator 15, and a digital data generation circuit 21 for digitally processing a meter control input for generating digital data representing an indication angle of an indicator. It further comprises an indication angle amount compensation arithmetic circuit 22 for performing addition or subtraction of the digital data generated by the digital data generation circuit 21 and indication angle amount compensation data B which is separately given, and circuits 23, 24 for converting output data from the indication angle amount compensation arithmetic circuit 22 into trigonometric function data and supplying a current amount according to the converted data to the two electromagnetic coils of the meter body.
