Notice for the Customers in Japan
The geared motor turns at 60 RPM if the mains frequency is equal to the one indicated
on the instrument plate. See also paragraphs 7 and 2.2.2.
In case a 37215 rated 50 Hz works at 60 Hz, the driving screw will turn at a speed 20%
higher; 20% lower in the opposite case.
The force applied to the paw at a different rate may impair the experiment consistency, in
particular if you compare the results gathered by two Analgesy-Meters and one of them is
fed by the “wrong” mains frequency.
In case of doubt, ask for advice; geared motors rated 50 or 60 Hz are generally available
at stock and they are easily interchangeable without special tools.

OPERATION
4.1
Preliminary
Make sure the mains cord and the pedal switch cables are properly connected, then
switch on the instrument using the switch located on the power module.
The ON position is confirmed by the LED placed at the base of the arm-supporting block;
check that the driving screw turns when the pedal switch is pressed.
4.2
Carrying out the Test
Position the slide (
7
) on the left end of the scale, with the pointer indicating zero, then
check the arm balancing (see paragraph 2.2.3). Adjust the position of the pusher to en-
sure that the arm (
3
) is horizontal for a given thickness of the paw.
An adjustable travel limit column (
11
) is provided to prevent the pusher to strike the
plinth, when the animal withdraws its paw; separate plinth and pusher by a 1-2 mm gap.
