Voltage supply for CTD4000-140
The CTD4000-140 calibrator operates with an operating
voltage of AC 100 ... 240 V, 50/60 Hz.
Voltage supply for CTD4000-375 and CTD4000-650
The calibrator runs on a voltage of AC 230 V or AC 115 V,
50/60 Hz.
The calibrator automatically sets the supply voltage to a
voltage of AC 115 V or AC 230 V.
The instruments can be supplied with voltage of AC 115 V or
AC 230 V (50/60 Hz).
The fuse must be changed, if the supply voltage changes
from AC 230 V to AC 115 V.
