• DO NOT operate damaged equipment. Remove power, and do not use the equipment until safe operation can be verified by service-trained personnel. Phenix Technologies, Inc. assumes no liability for unsafe or improper use of test equipment. DCD 4120-10...
SECTION 2: CONTROLS AND INDICATORS Control Unit (Refer to Figure 2-1) AC Power Input. Connect to a suitable grounded receptacle. See specifications tag on unit for voltage and current requirements. Voltmeter. Displays output voltage of test set. Currentmeter. Displays current out of high voltage lead or into RTN terminal depending upon mode of measurement.

CONTROLS AND INDICATORS Control Unit (Cont’d) Reset. Reset lamp illuminates to show that current trip circuit has tripped. High voltage circuits are deactivated. Momentary Reset switch must be pressed to extinguish Reset lamp to allow high voltage to be reapplied after returning Voltage Control to zero. VOLTMETER RANGE SELECTOR.

CONTROLS AND INDICATORS CONTROLS (Cont’d) High Voltage Unit (Refer to Figure 2-2) J5. Interconnect cable from controls connects here. Guard Terminal (GRD). Connect to Ground (GND) terminal (#3) for guard mode operation. Connect currents that need to bypass the currentmeter to this point. Low potential side of specimen must be isolated from ground to use this mode.

SECTION 3: ELECTRICAL SET-UP 1. Locate the desired location for the test set. Prepare the main power input cable for plugging into the proper facility power (i.e., 120 volts AC or 220 volts AC). Leave plug unconnected at this time. High Voltage Connection WARNING Main Power switch on front panel must be in the OFF (O) position before proceeding.
SECTION 4: OPERATING INSTRUCTIONS WARNING: This equipment should only be operated by personnel familiar with high voltage testing and safety procedures. Improper operation may result in injury or death and can cause damage to the unit or test object. Ensure proper electrical set-up has been performed. Check that the Voltage Control dial is set to "0"...

OPERATING INSTRUCTIONS Calculating Meg-Ohms The Impedance of a test object can be determined by the formula: V/I=R where voltage in Volts divided by current in Amps equals Resistance in Ohms. Resistance divided by 1,000,000 then equals Meg-Ohms: R/1,000,000=Meg-Ohms When voltages are in Kilovolts and currents are in Milliamps, a more direct method is to directly divide Kilovolts by Milliamps to obtain the result directly in Meg-Ohms.
SECTION 5: RETURN-GROUND-GUARD CONNECTIONS The unit contains a currentmeter feature useful in measurement of different current sources. 1. Return Mode (RTN) (Grounded Return Mode) This is the standard measurement configuration. The Ground jumper is installed between the Ground (GND) post and the Return (RTN) post. The low potential side of the test specimen is connected to Return.
SECTION 6: CALIBRATION CAUTION Calibration should only be done by persons familiar with High Voltage testing and safety procedures. All calibrations have been done at the factory. Periodic calibration of the output voltmeter and output currentmeter should be done annually. NOTE: Refer to Electrical Diagram Section for schematics pertaining to the model number of your test set.
Page 19
CALIBRATION Overcurrent This calibration should not need adjustment (factory adjusted). If the Overcurrent Circuit is out of calibration, perform the following steps. With unit off, short the output terminal to ground through an appropriate currentmeter. (A High Voltage Load will give better resolution and make calibration easier and more accurate. Minimum recommended resistance: 100K ohm, 100 watt.).
If the controls do not operate properly after having been used according to the instructions, the following hints may help. • Check main facility input power to the test set. • Check indicating lamps. (Spare lamps are available through Phenix Technologies.) • Check fuse-F1. • Check all external plug connections on the test set.
SECTION 8: STORAGE OF EQUIPMENT If the equipment will be stored for a prolonged period, the following precautions are recommended. 1. The equipment should be covered and kept in a warm, dry environment (95% maximum humidity, 5 to 40 Celsius). 2.
