For Safety
Warning Always refer to the operation manual when working near locations at which
the alert mark, shown on the left, is attached. If the operation, etc., is
performed without heeding the advice in the operation manual, there is a
risk of personal injury. In addition, the equipment performance may be
reduced.
Moreover, this alert mark is sometimes used with other marks and
descriptions indicating other dangers.
Warning
When supplying power to this equipment, connect the accessory 3-pin
power cord to a 3-pin grounded power outlet. If a grounded 3-pin outlet is
not available, use a conversion adapter and ground the green wire, or
connect the frame ground on the rear panel of the equipment to ground. If
power is supplied without grounding the equipment, there is a risk of
receiving a severe or fatal electric shock.
Warning This equipment cannot be repaired by the operator. Do not attempt to
remove the equipment covers or to disassemble internal components.
Only qualified service technicians with a knowledge of electrical fire and
shock hazards should service this equipment. There are high-voltage parts
in this equipment presenting a risk of severe injury or fatal electric shock to
untrained personnel. In addition, there is a risk of damage to precision
components.
Caution
Electrostatic Discharge (ESD) can damage the highly sensitive circuits in
the instrument. ESD is most likely to occur as test devices are being
connected to, or disconnected from, the instrument’s front and rear panel
ports and connectors. You can protect the instrument and test devices by
wearing a static-discharge wristband. Alternatively, you can ground
yourself to discharge any static charge by touching the outer chassis of the
grounded instrument before touching the instrument’s front and rear panel
ports and connectors. Avoid touching the test port center conductors
unless you are properly grounded and have eliminated the possibility of
static discharge.
Repair of damage that is found to be caused by electrostatic discharge is
not covered under warranty.

Note
If this particular InstaCal Module has been used previously to calibrate this Site Master, then the
Site Master senses the familiar InstaCal Module and automatically calibrates the instrument by using
the OSL procedure.
If the Site Master senses that the characterization data for the InstaCal Module that is connected to
this Site Master is different than the characterization data that is currently stored, then it displays soft
key options to keep or to replace the InstaCal characterization data.
Pressing the YES soft key transfers all of the characterization data from this InstaCal Module to the
Site Master. The transfer may take up to three minutes. This option is preferred if this InstaCal
Module is to stay with this particular Site Master. After calibration is completed, the data need not be
transferred again for this combination of Site Master and InstaCal Module.
Pressing the NO soft key temporarily transfers only the portion of the characterization data that is
necessary for this particular calibration. This transfer takes approximately 30 minutes to 60 minutes
and must be repeated every time that a calibration is performed by using this combination of
Site Master and InstaCal Module.
