FIRST AID
FOR ELECTRIC
SHOCK
RESCUi
FREE VICTIM FROM CONTACT WITH LIVE CONDUCTOR QUICKLY.
AVOID CONTACT WITH EITHER LIVE CONDUCTOR OR VICTIM’S BODY.
Shut off high uoltoge of once and ground circuit. If high voltage cannot
be turned off quickly, ground circuit.
An ax with odry wooden handle moy be used to cot high voltage line. Use
extreme caution to avoid resulting electric flash.
If circuit connot be broken or grounded, use odry board, dry clothing,
or other nonconductor to free the victim. '
NEVER ACCEPT ORDINARY AND GENERAL TESTS FOR DEATH
Symptoms of electric shock may include unconsciousness, failure to breathe
stiffness, as well as severe burns. WHENEVER
VICTIM IS NOT BREATHING PROPERLY, GIVE ARTIFICIAL RESPIRATION
START ARTIFICAL RESPIRATION IMMEDIATELY.
Perform artificial respiration ot scene of accident, unless victim’s or operator's life
is endongered. IN THIS CASE ONLY, remove victim to safe location nearby. If
new location is more than a few feet away, give artificial respirotion while victim
is being moved.
artificiol respiration, continue without loss of rhythm for at leost
FOUR HOURS, or until victim is breothlng without help. If you hove to change
operotors while giving ortificiol respiration, do so without losing rhythm of respiration.
Be prepored to resume ortificiol respiration, os he may stop breathing agoin.
COMPLETELY CONSCIOUS, give him astimulant (NOT AN ALCOHOLIC
DRINK) such os oteaspoonful of aromatic spirits of ammonio in o small gloss of water,
hot coffee, or hot tea.
Keep victim wcrm and lying down until he has been conscious for at least fifteen minutes.

5205A
POSITION VICTIM
Place victim in face—upword position and kneel close to his eor.
CLEAR THROAT
Turn head to one side and quickly wipe out any fluid, mucus, or
foreign body from mouth and throat with fingers.
OPEN AIR PASSAGE
Tilt heod back and extend neck to open air passage.
LIFT JAW FORWARD
Place thumb in victim's mouth and grasp jaw firmly. Lift jew
forward to pui! tongue out of air passage. Do not attempt to
held or depress tongue.
PINCH NOSTRILS CLOSED
With other hand pinch nostrils closed to prevent air leak.
FORM TIGHT SEAL WITH LIPS
Rescuer’s wide-open mouth completely surrounds and seals
open mouth of victim. This is not akissing or puckered
position —mouth of rescuer must be wide-open.
BLOW
Exhale firmly into victim's mouth until chest is seen to lift,
ihis can be seen by rescuer without difficulty.
REMOVE MOUTH AND INHALE
During this time, rescuer can hear and feel escape for air from
lungs. Readjust position if air dees not flow freely in and
out of victim’s lungs.
Continue at arate of 12 to 20 times per minute.
Breothing should be normal in rate with only moderate increase
in volume, so that rescue breathing can be continued for long
periods without fatigue. Do not breothe too forcibly or too
large avolume if victim is an infont or small child.

Section 1
ntroduction &Specifications
1-1. INTRODUCTION
1-2. The Model 5205A decision Power Amplifier is a
dc coupled, broad band inverting amplifier with aset gain
of 1(X). The 5205A may be used in combination with the
5200A AC Calibrator for acombined output ranging from
100 (100.000) to 1100 (1100.000) volts rms at frequencies
up to 100 kHz. When the 5205A is operating as an inde-
pendent amplifier ac voltages from OV to llOOV rms
at currents up to 200 mA rms may be obtained. The
waveforms may vaiy from alarge amplitude sinusoidal
to complex waveforms of DC, however, peak voltage
specifications limit the output to 1500 volts, DC vol-
tages from zero to 1500 volts may be obtained at cur-
rent levels of 100 mA
1-3. Control of the 5205Acan be exercised either
manually from the front panel controls or by remote
programming. Remote connectors for the 5200A and
acustomer supplied control source are provided on the
rear panel. Connection of the Model 5200A AC Cali-
brator with the supplied factory cable provides all the
analog signal and remote programming data required.
1-4. The amplifier output cable and the input for
independent operations are installed on the front panel.
Both may be installed on the rear panel for system op-
erations if desired as option —07. The standard output
cable is apermanently attached, three foot long, four
wire, low capacitance cable which allows remote sens-
ing, hi^ output current and hi^ frequency operation.
1-5. Equipment protection is provided by the Fault
and the Overload circuits. Activating the fault circuit
automatically reverts the unit to the Standby mode and
removes any voltage present from the output. Faults
can originate from procedureal errors or equipment fail-
ure. Afault due to procedural error can be removed
by resetting the systems and performing the restarting
procedure. An overload error can be corrected by re-
moving the overload from the circuit. Return to oper-
ate will occur automatically when the overload is re-
moved, unless the overload is accompanied by afault.
In this case, power must be removed and restored to
remove the indications.

EXTENDED USAGE
The 5205A will typically provide the following extended
output voltages and frequencies when the line voltage is kept
at the nominal value or above:
1) 1200V rms up to 120 kHz with 100 mA
output current capability.
2) ±1600Vdcpeak
OUTPUT CABLE
Extends three feet beyond the front panel. Special cable is
used to provicte remote sensing at the covered ckial banana
f^ug (with spacing) at the end of the cable. Astorage
receptacle is located on the front panel to hold the output
cable safely v#ien not in use. Option 07 routes the cable
out two feet beyond the rear panel.
LOCAL/REMOTE-5200A OPERATION
Atwo position switch, interlocked with either remote pro-
gramming function (see programming section below) or
manual programming. In the LOCAL mode, the operate
control is implemented from the front panel. In REMOTE,
control is obtained via the 5200A (Manual or Remote Mode)
or via the remote Input on the rear panel of the 5205A.
Three LED indicator lamps indicate which of the three pos-
sible controlling sources is in control (LOCAL, REMOTE or
5200A.)
SAFETY FEATURES
When the ac power is turned on, the amplifier is automatic-
ally set to the Standby condition and a114 by Vz inch red
arrow (lightning bolt) is illuminated to indicate that poten-
tially dangerous output voltages could be present due to re-
mote programming inputs. When output voltage is command-
ed by one of the three possible control scairces, a14 by 1inch
red "OPERATE” lamp is illuminated.
The 5205A cannot be commanded simultaneously by more
than one source. When more than one of the three possible
controlling sources calls the 5205A at the same time, the
5205A is returned to Standby and the LED "FAULT” lamp
is illuminated.
Two step turn-on is provided for ail three possible control-
ling sources.
a. Calling the 1000 volt range from the 5200A (local
or remote modes) causes the 5200A to return to
Standby. After a10 millisecond delay, the 5200A
operate command can then be initiated to provide
an output voltage from the 5205A.
b. Calling the 5205A from its remote input requires
two commands, 10 milliseconds apart. One is the
Remote Control Command followed by the Remote
0|:»rate Command.
c. Calling the 5205A from its Local Mode requires the
LOCAL/REMOTE-5200A Switch to be in tfie local
position, the Standby/OPERATE switch to be in
the STANDBY positicMi and then to be switched to
the OPERATE position.
The 5205A meets the safety requirements of lEC 348.
CALIBRATION REQUIREMENTS
The 5205A is calibrated at the factory by instrumentation
traceable to the National Bureau of Standards. Periodic cali-
bration of the 5205A's Calibrator Mode may be accomplished
through the use of an RMS differential voltmeter (Fluke 931B)
For calibrating the Amplifier Mode, aDVM such as the Fluke
8800A can be used with the equipment listed above. Ail other
adjustments can be made with general purpose laboratory
equipment.

2-20. OPERATING NOTES
2-21. AC Line Connections
2-22. Power is input to the unit on two separate lines.
One line provides power to the high voltage system while
the other supplies the auxiliary power system. Each input
line is individually fused. The voltage is selectable, as pre-
vioudy described and the input frequency may be either
50 or 60 Hz. Both input power cords have three prong,
polarized plugs. The round pin on the plu^ connect the
chassis to earth ground, therefore ensure that it is connect-
ed to ahigh quality earth ground.
2-23. The 5205A requires asignificant amount of line
power. Table 2-4 contains the RMS line currents under
full load conditions as controlled by line voltage setting
and input frequency. The requirements for both the hi^
voltage and auxiliary power line cords are listed. The high
voltage line cord is rated at 18 amps.

1POWER Switch Applies line voltage to the Auxiliary (AUX) power supplies. After
approximately 30 seconds power is applied to the High Voltage
(HV) supply.
2CONTROL Switch Selects between Local and Remote operation. Status Is shown
by associated indicators.
3LOCAL Indicator Illuminated when the power amplifier is operating in the local
mode, i.e., controlled from the front panel.
4REMOTE indicator Illuminated when the remote mode control line is active. The
power amplifier is controlled in this condition from acustomer
supplied control device.
;
55200 Indicator Illuminated when the 5200A is in the 1000 volt range to con-
trol operation of the instrument.
6WARM-UP Indicator
;
Illuminated for approximately 30 seconds after the POWER switch
has been turned ON. This allows the Power Amplifier time to heat
the tube filaments prior to applying high voltage to the system.
7MODE Switch Selects the mode of operation, STDBY or OPERATE. Resets the
system after afault when returned to STDBY from OPERATE.
This switch is active only in the Lcwal Mode of operation.
8STDBY-RESET
Indicator
Illuminated when the Standby or Reset fault Mode has been
selected.
9OPERATE Indicator Illuminated when the Operate mode has been selected.
10 FAULT Indicator Illuminated when afault occurs in the system. Aprocedural or
minor fault may be corrected and the indicator extinguished by
returning the unit to the Reset Fault mode. This can be accomp-
lished by setting the MODE switch to the STDBY-RESET posi-
tion and back to the OPERATE position, on the front panel in
the local mode, removing and then re-applying the operate com-
mand in the remote mode or returning the 5200A mode to stand-
by and then back to operate, either from the 5200A front panel
or the RCU, in the Calibrator Mode.
11 OVERLOAD Indicator Illuminated v\^en an overload is placed on the power amplifier.
To extinguish, power must be removed and reapplied. If accom-
panied by the fault indication, there is afault condition which
must be reset by turning power OFF and ON.
12 INSTRUMENT ON
Indicator
illuminated when the POWER switch is turned ON. Warns that
dangerous High Voltages are present in the unit and may be present
at the output terminals.

Washable filter to clean air used to cool the unit.
9Air Outlet Shield directs flow of air exhaust. Normally, exhausted air is
directed upward, however, the shield can be removed and reposi-
tioned to direct the air flow to the right of the instrument, if this
path of flow is obstructed in some manner. It should not be
positioned to the left toward the air intake or downwards.
2-24. The operator must verify that local and/or national
standards for outlet receptable and branch circuit are met.
For example: In the United States a20A rated branch cir-
cuit is required for a115V ac 60 Bz source. The 5205A
connectors are rated at 15A and can be plugged into either
a15A or 20A rated outlet.
2-25. Input Connectors
2-26. Control of the 5205A in the Remote or Calibrator
Modes of operation is from one of two connectors on the
rear panel. When operating with a5200A in the Calibrator
mode both input signal and controls are made through a
25-pin connector. Controls when operating in the Remote
mode are input on a 9-pin connector from acustomer
supplied control device.
2-27. When operating independently in either the Local
or Remote Mode the signal for amplification is input at a
BNC connector on the front panel. As part of the —07 Op-
tion, this connector can be placed on the rear panel for
system operations.
2-28. Output Connections
2-29. The output cable is permanently attached to the
unit at the front panel. As part of the -07 Option, it can
be attached at the rear panel for system operation. The 3-
foot long, four-wire, low capacitance cable has ahooded
protective cover for operator safety. Selection ofthe —07
Option for a rear connector reduces the length of the out-
put cable to two feet. Remote sensing is accomplished by

connecting the Oitput and Sense HI lines and the output
and sense LO lines inside the sealed protective cover.

2-30. Output Capabiiities
2-31. The 5205Acan deliver up to 100 mA dc and 200
mA rms ac. Attempts to draw currents in excess of these
amounts result in an overload which removes the output
and causes the amplifier to either retry its programmed out-
put or to return to standby. Before using the 5205 Aas a
source, insure that the recipient unit does not load the amp-
lifier in excess of these limits.
2-32. Ground Connection
2-33. If desired, the amplifier OUTPUT LOW can be
grounded to the chassis at the front panel by connecting
ashorting link between the two terminals. The chassis
ground is coimected to an earth ground throu^ the line
cords, provided the ac line cord is properly grounded. If
floating the amplifier output above ground is desired,
when the load cannot be disconnected from the earth
ground, remove the shorting link from between the two
front panel terminals and connect the OUTPUT LOW ter-
minal to the earth ground on the load. The maximum allow-
able differential between OUTPUT LOW and chassis ground
is lOV ac rms.
CAUTION!
The OUTPUT LOW terminal of the 5205A
should never be left floating during operation.
If the strap between OUTPUT LOW and
CHASSIS GROUND is not present, then
verify that through the output cable and
the load, aconnection with CHASSIS
GROUND is present.
2-34. Local Mode Operation
2-35. Operating in the Local Mode, the 5205APower
Amplifier will amplify and invert any signal input, (ac, dc,
or complex) with a gain of 100. Use the following proce-
dure for operation in the Local Mode.
2-8
a. Insure the CONTROL and MODE switches are
in the LOCAL and STDBY-RESET positions
respectively.
b. Connect the source to be amplified to the input
connector.
c. Insure the POWER switch is ON. The INSTRU-
MENT ON and LOCAL indicators are illuminated.
NOTE
The WARMUPIndicator is illuminated at initial
power application and stays on for approximate-
ly 30 seconds.
d. The STDBY-RESET Indicator is illuminated when
the WARMUP indicator goes off.
e. Set the MODE switch to OPERATE.
f. The OPERATE indicator is illuminated.
g. The signal input is present at the output terminals
with again of 100.
2-36. The system will not accept controls from two
sources simultaneously, therefore, if a5200A is connected
while operating independently, in the Local or Remote
Mode, and the 1000 volt range is elected, afault will result.
The fault can be removed and the indicator extinguidied
by removing the command from the 5200A and setting
the MODE switch on the 5205A to STDBY-RESET and
then OPERATE.
2-37. System or Combined Operations
2-38. While in the Calibrator Mode the 5205A can be
directly combined with a5200A for operation, or through
aRemote Control Unit (RCU) controlled by acomputer
test system. In the Remote Mode control is through a
customer supplied device which may be either manually
operated or a computer in a test system
2-39. Calibrator Mode Operation
NOTE
Duringcombinedoperations, the 5200A should
not be positioned on top of the 5205A. Over-
heating can result when the 5200Aintakes dis-
charged air ofthe 5205A. Also, transformer
coupling may result at line related frequencies.
2-40, 5200A LOCAL OPERATION
2-41. Once the 5205A is prepared for operation, i.e.,
the 5200 Control Cable connected, the POWER switch is
