Power Line Operation
This instrument can be operated from a power line voltage
of 90 to 136 V ac, 48 to 62 Hz. In Option 1, it can be
operated from 180 to 250 V ac (48 to 62 Hz) or 180 to
250 V de.
Operating Temperature
The 213 can be battery operated in ambient air tempera-
tures between -15 and +55°C (+5 and +131°F). It should
be connected to the power line only in ambient air tempera-
tures between O and +40°C (+32 and +104°F).
OPERATORS ADJUSTMENTS
AND BASIC DISPLAYS
This section provides instructions for making initial opera-
tors adjustments and obtaining commonly used basic dis-
plays. Since these procedures involve most of the controls
and connectors, they can be used for basic familiarization
on the operation of the instrument. Before starting the
checkout, either charge the batteries for at least 16 hours
or connect the instrument to the power line.

WARNING
I
When battery operated, store the power line
plug in the rear panel insulated compartment.
Potentials applied to the common connectors
may cause small amounts of current to flow in
the power line circuitry creating a possible shock
hazard on the power plug prongs.

_ WARNING
I
The probe common clip and the COMMON jack
are electrically connected to each other, and
potentials applied to one are present on the other,
creating a possible shock hazard.
~
The probe common clip and the COMMON jack
are electrically connected to each other and dis-
similar voltages applied to the common clip and
COMMON jack can cause equipment damage.
Operators Adjustments
The equipment required to make the initial operators ad-
justments is a screwdriver with a minimum blade size of
3/32 inch. To obtain the basic displays, a de source, an ac
source, and one or two resistors are required. Suggested
items for the basic displays are a battery, an audio signal
generator, a 3 kn resistor, and a 100 kn resistor- .
