MK-670 is used to assess the effect of drugs, brain damage, diseases on motor-coordination or fatigue resistance. Both rats and mice can be tested. Rod is divided into five (5) sections and each section can be used independently. Keypad and all the switches and indicators are located on the inclined front panel. The revolving speed can be set for the range of 1 – 20 RPM by 1 RPM steps. When animals stop running and fall off the rod onto the plates, the counting stops and staying time on the rod is displayed on LCD. Falling is detected by photo-beam.

The RS-232C interface is provided on the rear panel of the main unit. Using the attached Data Collection Software  (Windows Version) the data obtained can be exported to a personal computer and saved as a CSV file.

In addition to the conventional constant speed mode (MODE A), the 2 acceleration modes ( MODE B and C ) and the programming mode ( MODE D ) are  included in the standard system.

Main Features

• Each counter gets started or reset independently.
• The revolving speed can be set for the range of 1 – 20 rpm by 1 rpm steps.
• Constant or accelerated speed mode can be selected by the key.
•  Speed and acceleration rate are programmable.
• Cleaning work is very easy, since plastic trays are provided with each division for excrements.
• DCS-670 Data Collection Software comes supplied with the system.
• Printer is available as optional extra in two types —– Thermal and Dot-Impact. When printer is connected, test results will be printed out at the same time when animals fall.

MODE A

MODE A is the constant speed mode.  (1 – 20 rpm by 1 rpm steps)
Measurement in each lane starts and ends independently. When animals stop running and fall off the rod onto the plates, the counting stops and staying time on the rod is displayed on LCD.

PARAMETER    

• Test Number – Can be entered up to 10 digits
• Number of Revolution – 1-20 rpm ( by 1 rpm steps)
• Cutoff Time – 0-999 sec (by 1 sec steps)

• LCD
  Time elapsed in each lane,  Number of revolution
• Outputs
  Date, Mode, Test Number, Number of Revolution, Cutoff Time, Start and End Time in Each Lane, Staying Time on Rod

MODE  B

MODE B is the acceleration mode I.
Select number of revolution to reach finally and accelerating duration from the list below. (75 combination is available) Acceleration gets started for all the lanes when the rotor is in a state of complete stop. When the animal falls, time measurement of the corresponding lane will be stopped. When it reaches the preset number of revolution, it keeps on revolving at the speed. When all the animals fall, the measurement will be terminated and the rotor drum will come to a complete stop.

PARAMETER

• Test Number – Can be entered up to 10 digits
• No. of Revolution to Reach – 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80rpm (Select either)
• Accelerating Time – 60, 120, 180, 240, 300 sec (Select either)
• LCD
  Time elapsed in each lane,  Operation mode
• Outputs
  Date, Mode, Test Number, Number of Revolution to Reach finally, Accelerating Time, Start and End Time in Each Lane, Staying Time on Rod, Number of Revolution when animals fell

Example : Number of revolution to reach finally and accelerating time are 40 rpm and 60 sec, respectively

The rotor starts acceleration so that it will reach 40 rpm in a period of 60 seconds. When it reaches 40 rpm, it keeps the speed of  40 rpm. In this case number of revolution will reach 10 rpm in a period of 15 seconds and 20 rpm in 30 seconds.

MODE  C

MODE C is the acceleration mode II.
Select number of revolution to reach finally and accelerating time from the list. (45 combination is available)
Measurement in all the lanes starts at the same time when the rotor is revolving at the speed of 1/10th of  the number of revolution to reach finally. When the animal falls, time measurement of the corresponding lane will be stopped.  When  it reaches the preset number of revolution, it keeps on revolving at the speed. When all the animals fall, the measurement will be terminated and the rotor drum will come to a complete stop.

PARAMETER

• Test Number – Can be entered up to 10 digits
• No. of Revolution to Reach – 10, 15, 20, 25, 30, 35, 40, 45, 50 rpm (Select either)
• Accelerating Time – 60, 120, 180, 240, 300 (Select either)
• LCD
  Time elapsed in each lane,  Operation mode
• Outputs
  Date, Mode, Test Number, Number of Revolution to Reach finally, Accelerating Time, Start and End Time of Each Lane, Staying Time on Rod, Number of Revolution when animals fall

O: Measurement starts at the speed of 1/10th of the number of revolution to reach finally.
ts: starting point set up by the operator.
ts – tr: acceleration time.

Example : Number of revolution to reach finally and accelerating time are 40 rpm and 60 sec, respectively

The rotor starts acceleration when the rotor is revolving at the speed of 4 rpm so that it will reach 40 rpm in a period of 60 seconds. When it reaches 40 rpm, it keeps the speed of  40 rpm. In this case number of revolution will reach 13 rpm in 15 sec and 22 rpm in 30 sec.

 

Difference between MODE B & MODE C

	No. of revolution at the start of measurement	Pattern
MODE B	0 (Complete stop)	75
MODE C	1/10 of number of revolution to reach finally	45

MODE  D

MODE D is the programming mode.
Number of revolution and revolving duration can be programmed up to 6 steps. Measurement of each lane starts at the same time when the rod is in a state of complete stop. When animals stop running and fall off the rod onto the plates, the counting of each lane stops and staying time on the rod is displayed on LCD. The measurement will be terminated and the rotor drum will come to a complete stop either when all the animals fall or the preset program is finished.

PARAMETER

• Number of Step – Up to 6 steps
• No. of Revolution  – 1-60 rpm (by 1 rpm steps)
