1. If your motor/generator's shaft spins slowly (i.e., at
less than 50 rpm), getting an accurate reading may
require placing one or more additional squares of
reflective tape on the target. Begin by adding a second
square of tape on the circumference of the target 180º
from the first square (at 6 o'clock relative to 12
o'clock). Then perform Step 4 above, but divide the
display reading by two to account for the presence of
the second square. If the result is still unsatisfactory,
add another two pieces of tape at 3 o'clock and 9
o'clock and perform Step 4, but now divide the display
reading by four.
2. If bright ambient light is preventing the PCT2236B
from receiving the reflected beam, try shading the target.
STORING AND RECALLING RPM
MEASUREMENTS IN NON-CONTACT MODE
To store and recall non-contact rpm measurements, use the
same procedures for contact rpm measurements that you
simulated beginning on p. 8.
As in contact measurement mode, in non-contact mode
individual measurements or series of measurements can only
be stored while the Measurement button is pressed and held.
When the Measurement button is released, the contents of
the instrument's memory are frozen. When the Measurement
button is pressed again, the memory's contents are erased.
