4.0 OPERATION

4.1 Internal Triggering

1. DT-721 only: Firmly plug the power cord into a 100 VAC (Japan),

120 VAC (US) or 230 VAC (Europe) power source.

DT-725 only: Charge battery for approx. 15 hrs. before using strobe

for the first time (see section 2.3).

2. Aim light beam at the object under observation. The best distance

between the strobe and moving object is approximately 2 ft (61 cm).

3. Measure rpm by turning setter. Turn the setter to adjust the flashing rate

to the rotational speed of the object. To reach the desired rate faster, use

the 1/2 or x2 switches (see Section 2.1).

4.2 External Triggering

1. Connect wires according to connector

pin designation:

Tip: signal

Sleeve: Gnd (ground)

2. Pull power trigger switch and lock it.

When the ext phone jack is inserted

in unit, the strobe automatically switches

from the internal mode to the external.

3. The strobe will flash every time the sensor

puts out a pulse. Input signal requirements

are listed below:

a. 12 – 24 VDC thru a 3-wire NPN sensor.

(Requires external power supply).

b. 12 VDC thru a 2-wire proximity sensor.

(Leakage Current 1 mA max. Load

current 8 mA min.)

c. Switch or Relay Contact.

4. If the input signal frequency exceeds upper

or lower limits, the alarm mark will be

displayed and the strobe will stop flashing.
