SETTING THE TEST PARAMETERS
Model 5155 Dual Abraser
– The numerical
keypad is common to the entire instrument. The
digital display shows test cycles specific to each
turntable, and common functions to the entire
instrument (turntable speed and vacuum suction
level).
To change between the left or right turntables,
press either the START or STOP buttons on the
appropriate table. The last key depressed will
determine the side to which the data will be
entered, and is indicated by the word “KEYPAD”
displayed on the lower corners of the digital
display. For example, if the STOP key has been
depressed on the left side, any information
entered into the keypad will be for the left table.
Should the START or STOP key on the right
side be depressed, any values that are entered
will be for the right turntable.
Setting the Speed
The speed of the Rotary Platform Abrasion
Tester can be selected as 60 or 72 rpm. The
tester will store the speed that was last selected

the speed. To change speed, the instrument
must not be in operation (the Run or Reface

display “Stopped”).

The speed of the Rotary Platform Abrasion
Tester is reported as CYCLES / MINUTE, where
one cycle is defined as a full rotation of the
turntable.
NOTE:
The factory default speed is set at 60 RPM.
NOTE:
After pressing “1” or “2” in step 3, the display
screen will flash
“Test speed set to ‘X’ Cycles/Minute”
to confirm your selection and will automatically return
to the main display screen.

The turntables for the Model 5155 Dual
Abraser will rotate at the same rpm.
Setting the Reface Cycle Default
The Reface Mode allows you to reface the
wheels without adding test cycles to the
completed (remaining) test cycle count. This
convenient feature is ideal for any test that
requires the abrading wheels to be refaced at
intervals during the test.
The instrument is programmed with a default of
25 cycles. To change this value, follow the
instructions below.
