13、oltage Category I. This means the probe can only be used to make measurements on energy limited circuits within equipment. Examples include high voltage within televisions or photo copy machines. DO NOT use this probe to measure high voltages on power distribution systems. A 1000:1 voltage divider p

14、rovides the probe with a high input impedance. The divider also provides high accuracy when used with a voltmeter having a 10 megohm input impedance. A molded plastic body houses the divider and protects the user from the voltage being measured. Specifications The 80K-6 will achieve rated accuracy w

20、ld be familiar with, and exercise, all possible high- voltage safety practices. When handling the probe the following additional cautions must be taken: When making a measurement, never make body contact with the probe tip or the red portion of the probe. Always hold the probe by its black handle. B

21、efore making a measurement, make sure that the ground side of the output connector is connected to the voltmeters common terminal. The clip lead must be attached to earth ground. Do not use the probe if it is damaged. Before using the probe, inspect it for cracks or missing plastic. Pay close attent

22、ion to the probe body, tip and insulation surrounding the connectors. Make sure the tip is firmly attached to the body. When servicing, use only specified replacement parts. Do not operate probe around explosive gas, vapor or dust. Do not use the probe if it operates abnormally. Protection may be im

23、paired. When in doubt have the probe serviced. Voltmeter Compatibility The 80K-6 is compatible with any ac or dc voltmeter that has an input impedance of 10 megohms 10%. Voltmeters with higher input impedances require the use of an external shunt to obtain an accurate measurement. Use the following

24、formula to determine the value of an external shunt resistor: Rs Rm x 10 Rm10 = Where: Rs= Shunt Resistance in Megohms Rm= Voltmeter Input Impedance in Megohms ( 10 megohms) Circuit Loading The 80K-6 represents a load of approximately 75 megohms to the circuit being measured (13 A per 1 kV). See Fig

25、ure 1. To more accurately determine the load resistance, measure the resistance of the 80K-6 at its voltmeter connector and multiply the measured value by 1000.

26、ollowing procedure to operate the 80K-6: 1. Inspect the probe. (Refer to the preceding Warning.) 2. Connect the probe cable to a compatible voltmeter. (Refer to the preceding Warning.) Use a shunt resistor if required. 3. Select an appropriate voltage range (1 volt reading per 1000 volt probe input)

27、. 4. Connect the ground lead of the probe to earth ground. (Refer to the preceding Warning.) 5. Hold the probe by the black handle and connect the probe tip to the circuit being measured. Observe the voltmeter reading. Maintenance Performance Test Verify the probe accuracy by measuring a 5 kV dc 0.2

28、5% voltage source. When used with a compatible dc voltmeter, the probe should accurately measure the source voltage to within 1%. No calibration adjustments are provided on the probe. Cleaning Use a soft cloth dampened with distilled water to clean the 80K-6. Never use solvents or abrasive cleaners.

29、 Disassembly Use the following procedure to disassemble the probe: 1. Unscrew the black handle from the probe, and slide the handle onto the cable. 2. Unscrew the metal tip one turn, and push in on the tip until the internal assembly snaps free of the housing. Remove the tip. 3. Withdraw the interna

30、l assembly from the probe by pulling the metal ring over the threads on the probe body. 4. Logically reverse this procedure to reassemble the probe. Caution To avoid probe damage after repair, measure and, if necessary, adjust the outside distance between the ring and the probe coupling on the inter

31、nal assembly before reassembling the probe. The distance must be 4.9100.020 inches. Make the adjustment using the solder connection at the rear of the metal probe coupling.
