NOTE
By selecting a pulse input to channel B, the 3193 frequency measurement
function can be used to measure a frequency. By setting the unit designation
to "rpm" this can be used to directly display the rotation speed of a motor or
other device.
1. Display the " EXT UNIT " page on the STATUS
screen.
2. Using the
CURSOR
keys, move the cursor
to"
VOLTAGE RANGE
" for channel B, and press
F4
(PULSE)
If the unit designation is set to " rpm ", it is
necessary to set the number of pulses input per
rotation. In this case, set the Scaling item to the
number of pulses for each rotation of the motor.

･ Setting a pulse input signal to channel B unconditionally assigns the
frequency measurement function of the 3193 to fc. This ends any previous
source set for fc.
･ The frequency range of fc is set to auto-ranging. To fix the frequency range,
set the range on "
FREQ/OUTPUT " page on STATUS screen.

cm) and the units for channel B are set to rotation rate (rpm), then the
following expression is automatically evaluated and displayed.
The calculation expression depends on the torque units, and care should
therefore be taken when setting the units.
