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.
