Portable DC Hypot
Information
LINE CABLE
Three conductor input cable terminated in standard
'three-prong grounding type plug.
HIGH VOLTAGE CABLE
Single conductor high voltage cable terminated in male
connector and in-' sulated clip for connecting item to high
voltage output.
RETURN CABLES
Single conductor cables each terminated in spade lug and
clip for connecting the test item to the RETURN terminals.
HIGH VOLTAGE OUTPUT RECEPTACLE
Female connector to receive the high voltage output cable
connector.
POWER SWITCH/CIRCUIT BREAKER/ INDICATOR
Makes or beaks all primary power (line voltage) to the
instrumentB The illuminated switch indicates line power is
available to the high voltage control circuit and any
internal assemblies.
HIGH VOLTAGE SWITCH
Operating in the primary side of the high voltage control
circuit it controls the energizing and de-energizing of high
voltage.
HIGH VOLTAGE INDICATOR
Red lamp indicates the high voltage control circuit is
energized and high voltage is available at the output 3
KILOVOLTS RANGE SWITCH
Allows selection of the full scale range of the
KILOVOLTMETER for more accurate setting of the output voltage *
VOLTAGE CONTROL
Permits continuous adjustment of the test voltage to the
desired value from zero to maximum output of the instrument.
KILOVOLTMETER
Connected directly across the output to indicate correctly
the voltage actually being applied to the test item, and is
therefore independent of internal regulation.
MICROAMPERES RANGE SWITCH
Operating in the electronic metering circuit, this four
position selector switch provides for changing the
sensitivity of the Amplifier to obtain the best meter
readability. The MICRO-AMPERES range indicates full scale
sensitivity of the microammeter.
MICROAMMETER
The MICROAMMETER indicates the leakage current in the
METERED RETURN side of the output circuit. The meter is
driven by a high gain balanced bridge electronic Amplifier
and is electronically protected against burn-out should it
be accidentally overloaded.
HIGH VOLTAGE Power supply
The high voltage dc Power supply uses long life silicon
rectifiers. For operator safety and protection of the power
supply against' "overloads a high reactance transformer is
used. A high reactance type transformer is designed so that
the output voltage will collapse should the current output
exceed a given value. The chief advantage of the high
reactance transformer is this inherent current limiting
action which eliminates the need for a circuit breaker and
pre~ vents destruction of the item under test. Since current
limiting does not depend on mechanical parts, its action is
instantaneous and affords operator protection.
