4. When the power supply is switched on soft start circuitry will turn the lamp on slowly to minimise thermal shock to the cold lamp which would otherwise reduce lamp life To change the light intensity simply rotate the intensity control knob found on the top panel of the power supply If battery power 1s used or cuts in due to a mains power interruption a slight decrease in light intensity may be noticed This is normal and the amount of light reduction will depend on the charge status of the battery being used Intensity control knob Mains switch Lamphouse cable socket Scan Optics recommend the use of gel cell or sealed rechargeable lead acid 12V batteries These batteries are maintenance free and can be operated charged or stored in any position without leakage I Tf the power supply is to be connected to a 12 volt de supply connect the battery cable to the 3 pin connector on the bottom panel on the power supply 2 Connect the red battery clip to the positive battery terminal and the black clip to the negative battery terminal The power supply will not operate 1f the terminals a
5. S0 111W Microscope The microscope arm is fitted with an adjustable gas spring By adjusting the position of one end of the gas spring the amount of upward force can be changed Thus if accessories are added to or removed from the microscope the force setting can be adjusted to compensate for the change in weight thereby maintaining the same desired feell of the arm movement To adjust the gas spring 1 With one hand push the pantograph arm down until it is in the horizontal position This will expose the socket in the adjusting screw 2 Using the 5mm socket key provided in the tool box rotate the screw clockwise to move the adjusting nut up and decrease the arm force Alternatively rotate the screw anti clockwise to move the nut down and increase the arm force CAUTION Always check the arm movement over the entire up down stroke of the arm If the microscope is heavily loaded with accessories and the arm force is set too low the arm may drop suddenly if it is not adequately restrained with the friction lock Gas spring adjustment shaft Ga
