3.  For Windows 3.1 go to Program Manager and pull down the FILE menu. 

Select RUN. 

4.  For Windows 95, choose RUN from the START menu.  

5.  At the prompt, type:  

6.  a:\scope\setup (ENTER) (if you placed the diskette in Drive A) or 

b:\scope=setup(ENTER) (if you placed the diskette in Drive B) 

7.  Follow the on-screen prompts to complete the installation.  

8.  To run the program, double-click the SCOPE-VIEW icon, Follow the on-

screen help for specific operation instruction. Also, refer to the README file

10. MAINTENANCE 

 

10.1 Fuse Replacement 

Remove power to the meter and removal all connected cables and probes. Use a 

suitable Phillips screwdriver to carefully open the case. Remove the defective 

fuse(s) and replace it with a new one of the same type and nominal current (0.8A 

fast blow, 250 V); usual name: F 0.8A/250A or F 800Ma/250V. For the amperage 

range 20 A ultra rapid, 250V; usual name F 12A/250V (BUSSABC12). After the 

fuse has been exchanged close the cabinet. 

10.2  Battery replacement

 

Remover power to the meter and disconnect any cables or test leads. Open the 

battery compartment by removing the rear battery compartment screw with a 

Phillips screwdriver. Exchange battery and reinstall the battery compartment
