Product catalog summary

Introduction
The MOVISTROB® products undergo extensive quality and function tests to ensure safety and performance. Users are advised to read the operating instructions thoroughly to prevent damage or injury.

General Description
The MOVISTROB® 2500 is a digital stroboscope designed for studying rapid, periodic motions through short light flashes. It is known for its high time stability, accuracy, ease of use, and low maintenance costs. The device is menu-driven, facilitating easy operation even after long periods of non-use.

Controls and Indicators
The device includes an LC-Display, arrow keys, a mode key, and a unit key. It has connections for power, external control, and a serial interface. The flash bulb is protected by a transparent cover, which can be replaced with a red filter to reduce eye strain.

Menu Structure and Mode Selection
All operating modes are accessible via a menu, allowing for frequency measurement, flashing frequency generation, and phase displacement adjustments. The menu enables easy mode switching and setting adjustments.

Individual Modes

Frequency Measurement (MEASURE Mode): Provides precise speed measurement with high accuracy, with triggering set to line frequency or external signals.
Phase Displacement (PHASE Mode): Synchronizes flashing with line frequency or external signals, allowing phase displacement settings.
Flash Frequency Generation (GENERATE Mode): Generates flashing frequencies with adjustable units and a double flash function for speed adjustment.

RS 232 Serial Interface
The stroboscope can be controlled via a serial interface, allowing integration into automated systems. Data is transmitted in ASCII code, and transmission parameters can be configured in SERIAL mode.

Storing Settings
All current settings can be stored as standard settings for when the device is switched on.

1. Description of Inputs and Outputs
The device operates with a +12V DC input across a 150 KΩ resistor for switching contact. It has four inputs ranging from 0.5 to 50V with a resistance of 50 KΩ, and a signal ground. External connections are made via a seven-pole diode plug with a bayonet lock. The socket pin assignment includes +12V DC, signal ground, and opto outputs.

2. Stroboscopic Principle
Stroboscopy allows observation of high-speed periodic motion by illuminating the object with brief light impulses. The object appears motionless or in slow-motion at the appropriate flash frequency. The highest flash frequency that produces a stopped image equals the object's revolutions. RPM and frequencies can be measured by determining the highest flash frequency or two neighboring flash frequencies.

3. Slow-Motion Cycle
If the flash frequency period deviates slightly from a whole-number multiple of the rotation time, the object appears to rotate slowly. The apparent angular speed is influenced by the deviation from the whole-number multiple.

4. Stopped Images of Phantom Objects
Stopped images can occur at other flash frequencies, representing phantom objects. These images are less distinct as the number of marks increases.

5. Objects with Finite Rotational Symmetry
For objects with symmetrical axes, stopped images result from specific flash frequency periods. Phantom images also occur under certain conditions.

6. Replacing Flash Tube
If the flash tube fails, it must be replaced by removing the protective cover and ensuring the device is off. The new tube should be inserted carefully, and the device should not be operated until the housing is closed.

7. Maintenance and Repair
If the instrument is unsafe, it should be taken out of operation. Repairs should be conducted by trained personnel or returned to the manufacturer.

8. Technical Data
The device features internal and external flash triggering, a frequency generator with a resolution of 0.01 Hz, and a frequency range of 1 Hz to 300 Hz. It supports various measurement units and has a serial interface for data exchange. The power supply ranges from 90V AC to 240V AC or DC voltage from 100V to 340V. The device dimensions are 110 mm x 206 mm x 63 mm, and it weighs approximately 0.9 kg.

The stopped image shows k marks, which are arranged in the corner of a regular k-angle. Only a very few of the theoretically infinite number of flash frequencies...
