6.1 Power 

 

After certify the power for using is the same as the power that designate in wiring diagram, you may wire. 

In order to protect a surge, you may separate an instrument power and a power line (operation power of 

heater, magnet S/W)   

 

6.2 Single case wiring 

 

Fig. 6.1 shows the function of terminal board at backside when an instrument is used for single case.
