5.2 LEVELING THE TESTER
For proper operation, the PK II tester should be placed on a support that is solid and free from
vibration.
5.2.1 Coarse Leveling
Both coarse and fine leveling are supported
by the PK II tester. Coarse leveling to raise
the tester is achieved by pushing the knurled
rod (located inside the case on either side of
the weight insert) and rotating the knurled
nut until it contacts the bottom of the case.
5.2.2 Fine Leveling
Fine leveling is obtained by rotating the
knurled rod clockwise to raise and counter-
clockwise to lower the tester.
A third adjustable foot is located under the
PK II case between the inlet and outlet valves.
A bull ’ s-eye level is located on the cover
plate for sighting level accuracy.
For coarse adjustment, use the knurled rod located on the top.
For fine adjustment, hold the bottom foot and rotate the knurled
knob at the top.
