■ SCALING FACTOR
Positions for the rotary switches 10
respectively to each digit of the decimals and exponential
as shown below.
Output Rate = Input Rate × 0. (A)(B)(C)(D) × 10
where the scaling factor is adjustable from
1.0000 × 10
[Examples]
Scaling factor 0.1440:
(A) = 1, (B) = 4, (C) = 4, (D) = 0, (E) = 0
Scaling factor 1.0000 is special:
(A) = 0, (B) = 0, (C) = 0, (D) = 0

■ RIGHT SIDE VIEW ■ PULSE WIDTH
Factory adjusted to a suitable value. Use only when the out-
put device (counter) is not able to read the output pulses.
Min. 400 µsec. recommended for AC/DC switch output of
which the internal voltage drop value may increase with a
shorter pulse width.

■ PULSE WIDTH RANGE
Selects adjustable range of the output pulse width.
L (Left)
CTR (Center)
R (Right)
■ PULSE SENSING TYPE
Provided only when the voltage pulse input is selected. Fac-
tory set to 'DC coupling.'
When the DC offset is too large to detect by DC coupling,
switch to 'Capacitor coupling.'
CHECKING
apply
–n
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
–(E)
13 – 14 with a multimeter.
3) Input: Check input terminal 1(+) – 4(–) with an oscil-
loscope.
With voltage pulse input, the signal should be below 1V
at L level, while it should exceed 2V at H level.
4) Output: Check that the load resistance meets the de-
scribed specifications.
