displays. A spare battery is included with the meter.
Separate the two halves
of the unit by twisting the
yellow locking ring
anticlockwise and pulling
apart.
Open the blade
retaining wings. Lift
out the plunger and
blade assembly.
Separate the blade
and yellow feeder ring
from the plunger.
Clean all components

A worn Grinder Blade and
Feeder Ring causes inaccurate
readings. Check regularly and
replace (see below) if worn or
