2.2.3. Basic Connections

Power Cable
The instrument is shipped with a line cord containing a protective earth ground. When
the line cord is connected to an appropriate AC power source the cable will connect
the chassis to earth ground.
protective conductor.
cord must include a NEMA5-15 style male plug, SVT or SJT cord sets, and be rated
for at least 125VAC, 10A. Number 18 gauge wire or larger must be used.
Return Connection
When the instrument's return is grounded, any internal and external stray leakage will
be monitored due to currents that flow from high voltage to earth ground (such as from
high voltage to the chassis of the instrument). These currents are inherent and will
cause errors when trying to monitor very low leakage currents in the microamp range.
The output power supplies of this instrument are referenced directly to earth ground.
Any conductor that completes a path between the high voltage and earth ground will
form a completed circuit.

2.2.4. Environmental Conditions

This equipment is intended for indoor use only. The equipment has been evaluated
according to Installation Category II and Pollution Degree 2 as specified in IEC 664.
This instrument may be operated in environments with the following limits:
Temperature..................... 32° - 104° F (0° - 40°C)
Relative humidity.............. 0 – 80%
Altitude............................ 6560 feet (2,000 meters)
NOTE: Keep the ventilation slits uncovered during operation. Failure to do so
could cause the instrument to overheat and may damage internal components.
Storage and Shipping Environment
This instrument may be stored or shipped in environments with the following limits:
Temperature..................... -40° - 167° F (-40° - 75°C)
Altitude............................ 50,000 feet (15,240 meters)
The instrument should also be protected against temperature extremes that may
cause condensation within the instrument.
