INSTALLATION
2.3 Power Line Connection
This instrument uses a standard IEC input module.
The input fuse is located in the drawer above the
input power module. If it has to be replaced, be sure
to use a "slow blow" fuse, 250 V, 6/10 A, 5x20 mm.
See Figure 2-1.

2.4 Line-Voltage Regulation
The accuracy of measurements accomplished with
precision electronic test equipment operated from
ac line sources can often be seriously degraded by
fluctuations in primary input power. Line-voltage
variations of ±15% are commonly encountered, even
in laboratory environments. Although most modern
electronic instruments incorporate some degree of
regulation, possible power-source problems should
be considered for every instrumentation setup. The
