1.4 Installation

1.4.1 General Installation

Unpack Instrument
Carefully unpack the instrument, removing it from its plastic bag. Report any damage to
your freight carrier at once. The box should also contain the User's Manual and a serial
cable.
NOTE: Retain the original packing material for future use in the event that the instrument
is shipped to another location or returned for service.
Instrument Mounting and Use
Place the instrument on a flat working surface capable of safely supporting the weight of
the instrument (approx. 10 lbs, 4.5 kg). Excessive vibration during reading may cause
poor repeatability; thus, a sturdy working surface is required. A clearance of at least 3
inches (8cm) around the instrument is required to assure optimal ventilation. It is
recommended that the instrument be operated within an ambient temperature range of
18-35°C and humidity of less than 85%.
Power Switch Position
When installing the power cord or if changing the setting on the voltage select switch the
unit should be turned off. Look at the rear panel of the instrument to check that the power
switch is in the Off position. A diagram of the rear panel can be found in Section 1.5
"Parts and Controls".
Power Cord Requirements
Use only the power cord specified for this product and certified for the country of use. For
110-120 V units used inside the US use a UL listed cord set consisting of a minimum 18
AWG, Type SVT or SJT three conductor cord, maximum 3 meters (10 feet) in length,
rated 10 A, 125 V, with a parallel blade, grounding type attachment plug.
For 220-240 V units used inside the US use a UL listed cord as above, except rated 250
V, with a tandem blade, grounding type attachment plug. The cord set provided by the
manufacturer meets these requirements.
Safety Grounding
Do not alter or defeat the safety grounding methods provided. To avoid the risk of electric
shock, the third prong of the AC power plug must be connected to conductive parts
internal to the equipment. Internal fasteners to grounding points are marked by the IEC
417 symbol 5019 . DO NOT loosen or remove these fasteners or connections. An
alternate method of grounding is provided by connecting the grounding terminal located
on the rear panel, to a suitable ground.
To avoid electric shock, the power cord protection ground conductor must be connected
to ground.
Voltage Select Switch
Locate the voltage select switch on the rear panel. This is a 2-position slide switch that
will configure the instrument to accept either 230V or 115V input. Do not connect
equipment to the power supply before changing the line voltage selection switch.
