This switch has five positions:
The instrument is disconnected.
The instrument is powered from the mains. Accord-
ing to the mains voltage the proper voltage must be
selected by the switch-fuse combination situated at

16 hours approx.).
With the POWER SWITCH in this position the

bett er than 2% from 0- 50°C. Output impedance
less than 1 Q.
