Chapter 5 Maintenance
■
5.1 Daily maintenance
● In order to retain the accuracy and precision of this instrument, daily maintenance is necessary.
(1)
Wipe the pole faces of the measuring yoke with a clean, soft, and dry cloth after testing
.
This helps prevent rust on the pole faces.
*
Be careful not to cut your hand with the edges of the pole faces.
*
Never polish the pole faces with sandpaper or the like. This would cause an increase in core loss of the
yoke, leading to incorrect measurement.
(2) Lightly wipe the measuring yoke, except its pole faces, with a soft cloth, moistened with a small amount of
diluted neutral detergent.
Never use organic solvent; doing so may cause discoloration and corrosion.

5.2 Calibration
● Measurement accuracy and precision of this instrument may fluctuate with long-term use, depending on the
environment or frequency of its operation. Calibration at least once a year is recommended. For details,
