3 HVC-804 DC High Voltage High Impedance Meter 2

4 General Safety Instructions: Bench-type high voltage meter, HVC-804, is a high voltage probe with a special connector design that has high input impedance (10GΩ), and high resolution reading (0.0001KV) which is easy and safe to operate. Because of the 10GΩ high input impedance provided on the HVC-804, the loading effect is minimized. This way, the actual voltage value of the to-be tested circuit can be more accurately presented. Meanwhile, it also minimizes the errors applied to the test circuit. For instance when measuring the high voltage of CRT, cases like deviation of focus, unexpected image enlargement, or changes in the brightness, such similar abnormality can all be improved immediately. In addition, the high input impedance of 10GΩ will become the best partner for high voltage low current output devices or for measurement of static equipment. HVC-804 has a 3- range voltage selection switch. The users can select either 2KV, 20KV and 40KV for different application and resolution. When switching to a different voltage, all the ranges have the insulation protection circuit of a 40KV. The built-in HVP-40 designated input end of this high voltage attenuation probe can replace the DC only digital electricity meter of a fixed 10MΩ input impedance. Its LED display reading has correctly been converted, and can directly be loaded. Please do not connect HVP-40 to auto range DMM. The auto range will change input impedance and make the error to convert the high voltage impedance value. HVC-804 is able to replace fixed style 10MΩ input impedance DMM directly. Read carefully this manual before using the instrument and respect the safety precautions. 3

This way, the actual voltage value of the to-be tested circuit can be more accurately presented. Meanwhile, it also minimizes the errors applied to the test circuit.

5 Safety Precautions: The steps outline the minimum basic safety precautions that must be followed when using this instrument. (1) Do not use the instrument in a damp environment or where there is risk of explosion. (2) Examine the instrument and make sure it is clean and dry. If in doubt, wipe with a clean, dry, lint-free cloth. (3) Look at the condition of the floor. It must be dry, clean and free of oil. (4) Verify that you are able to remain clear, dry and avoid contact with any exposed metal and / or other conductive material. (5) Examine the 1/1 probe before use. Make sure that it is in good condition. Any damage on the surface of the wires could cause you serious personal harm. (6) Only use the 1/1 probe accessory for directly high voltage measurements. (7) Examine the entry to your High Voltage test point. Make sure that you are able to bring the probe in to the point. (8) Always work within sight and hearing of another person. If an accident occurs, you will be aided quickly. 4

If in doubt, wipe with a clean, dry, lint-free cloth. (3) Look at the condition of the floor. It must be dry, clean and free of oil.
