Product Information: Digital Synthesis, High Reliability, Xenon Tube

STROBOSCOPE DT-2349

The Digital Synthesis, High Reliability, Xenon Tube STROBOSCOPE DT-2349 is a device that is used to measure and analyze the motion of an object. It uses a xenon tube to produce brief and rapid flashes of light to create an illusion of a stopped or slowed-down motion. It has a digital synthesis feature that allows for accurate and reliable measurements. The stroboscope can be used for motion analysis and inspection in various industries such as automotive, manufacturing, and research.

Product Usage Instructions:
Before operating the stroboscope, it is important to read the instruction manual carefully.

Checking Motion

1. To stop motion at 2:1, 3:1, 4:1, etc., turn the dial until two images appear. This will double the actual speed.
2. Lower the flashing rate until a single and stationary image appears. This is the actual true speed.
3. For motion analysis, locate the actual speed as mentioned above and turn the dial slowly up or down. This will give a slow motion effect allowing complete inspection.

Flash Tube Replacement
The flash tube requires changing when the instrument starts to flash erratically at speeds of 3600 RPM/FPM or more.

Caution: Flash Tube Replacement should only be done by a  qualified technician as the instrument contains no user serviceable parts.

1. Loss (rotate) the Front Cover Screws 11 ( 3-:8, Fig 1) and take away the Front end protection cover.
2. There is a plug and the socket for connecting the tube with the main instrument. Take away the tube and replace the new unit.
3. Install the front top cover and end protection cover again.

With proper usage and maintenance, the Digital Synthesis, High Reliability, Xenon Tube STROBOSCOPE DT-2349 can provide accurate and reliable motion analysis and inspection for various industries.

Warning!
Do not look directly at strobe/reflector. Light pulses at the frequency greater than 5 Hz may cause photosensitive epilepsy in some individuals if directly viewed.
A feature of the instrument is to make moving objects appear to be stationary. Precaution should therefore be taken to ensure that there is no physical contact made with objects being viewed.

4.  bo not use fingers or any tool to touch the II Xenon tube 11 ( 3-9, Fig. 1 )
   Caution:
   Do not use fingers or any tool to touch the II Xenon tube ”
   Risk of electric shock !

Checking Speed {RPM/FPM)

1. Power off the installation to be measured, make a 11 mark II on the rotation area where it is intended to measure the RPM, then power on the installation to be measured.

2. Press the II Power switch 11 ( 3-1, Fig. 1) to turn on the Stroboscope.
   1 “position is power on. 0 ,, position is power off.

3. The display will show 11 100.0 11 RPM ( FPM ), it is the default value.
   Use the II x 2 button 11 ( 3-7, Fig. 1 ) to adjust the display value near the estimate setting signal’s RPM approximately ..

   • Press the x 2 button “once will double the  display value.
     For example, the display is 11 100. 0 11, press the 11 x 2 button “, the display will change to “200. 0 ‘
     Press once again, the display will change to ” 400.0 ‘·-··

   • Press “+ 2 button ” ( 3-6, Rg. 1 ) will divide the display value by two.
     For example, the display is 11 400. 0 ‘press the + 2 button “, the display will change to “200. 0 ‘

   • Press once again, the display will change to II 100,0 1,..,

4. Setting value by ” Digital adjusting knob “

Rotate II Digital adjusting knob 11 ( 3-3, Fig. 1 ) to adjust the exact display value.

• Turn the knob to clockwise direction will increase the display value.
• Turn the knob to counter-clockwise direction will decrease the display value.
• If rotate the knob slowly, the display value will change with high resolution-( change just with 1 digit).
• If rotate the knob fast, the display value will change with low resolution ( change with more digits).

Setting value by ” + button ” , ” – button ”
Use the 11 + button 11 ( 3-5, Fig. 1 ) , ” – button 11 ( 3-4, Fig. 1 ) to adjust the exact display value.

• Press the 11 + button ” once ( continuously ) will increase the display value.
• Press the 11 – button II once ( continuously ) will decrease the display value.
• If press the button once, the display value will change with high resolution ( change just with 1 digit).
• If press the button continuously, the display value will change with low resolution ( change with more digits).

When checking the speed, care must be taken to ensure that the strobe is flashing in unison (one to one) with the object being monitored.

5. The Stroboscope will also stop motion at 2:1, 3:1, 4:1 et., this is normally referred to as harmonics. To ensure unison, turn the dial until two images appear – this will double the actual speed. Then lower the flashing rate until a single and stationary image appears – this is the actual true speed.

Checking Motion
For motion analysis, simply locate the actual speed as mentioned above and then turn the dial slowly up or down. This will give a slow motion effect allowing complete inspection.

FLASH TUBE REPLACEMENT

The flash tube requires changing when the instrument start to flash erratically at speeds of 3600 RPM/FPM or more.

Caution:

• Change of the Flash Tube should only be done by a qualified technician. As the instrument contains no user serviceable parts.
• Before replace the tube, should power off the meter, and wait at least 15 minutes until the circuit be discharged completely.

1. Loss (rotate) the” Front Cover Screws 11 ( 3-:8, Fig 1, and take away the ” Front end protection cover 11•

2. There is a plug and the socket for connecting the the tube with the main instrument.
   Take away the tube and replace the new unit.

3. Install the front top cover and end protection cover again.
