10、N AND OPERATING THE INSTRUMENT. 1.1DESCRIPTION This instrument must be operated, used and serviced ONLY by trained, qualified personnel. Misuse of electrical instruments can result in personal injury and damage to the apparatus under test. Obey all applicable safety rules and regulations at all time

11、s. Refer to the following sections of this manual for operating specifications and procedures. 1.2EXPLANATION OF SAFETY SYMBOLS AVO International uses, where applicable, the following IEC 417 symbols on its instruments: This symbol indicates that the operator of the instrument must refer to the inst

12、ruction manual for further explanation and clarification. ? ? ? ? ? Safety Ground Terminal. This terminal must be connected to an earth ground before making other connections to the instrument and prior to operating it! This red symbol indicates that high voltage (i.e., any voltage equal or greater

13、than 1000 Volts) is present on the terminal. Use extreme care. This is the symbol for a sinusoidal AC voltage or current. AC or DC voltage. 2 1.3GROUNDING Where a ground binding post or a grounding lead is provided on the instrument, it must be connected to an earth ground PRIOR to making any other

14、connections. WARNING: To avoid electric shock do not interrupt the connection to the protective safety ground. 1.4POWER CORD AND FUSES The power cord must be connected to a grounded supply system with proper electrical ratings, as indicated on the instrument. In the case of detachable power cords, o

15、nly the cord supplied or specified by AVO International should be used. WARNING: TO AVOID ELECTRIC SHOCK ALWAYS DISCONNECT THE POWER CORD FROM THE SUPPLY CIRCUIT BEFORE SERVICING THE INSTRUMENT OR WHEN REPLACING A FUSE. WARNING: ALL FUSES MUST BE REPLACED WITH THE SAME TYPE AND CURRENT AND VOLTAGE R

16、ATINGS. SHORT-CIRCUITING THE FUSEHOLDER IS PROHIBITED. 3 2GENERAL INFORMATION 2.1DESCRIPTION The AVO International POWER MULTIMETER (Model PMM-1) is a next generation portable battery/line operated multifunction instrument for measuring AC or DC voltage, AC primary and secondary current, power, reac

17、tive power, phase angle and frequency of a single or three phase electrical system. POWER MULTIMETER is easily configured to measure the amplitude and phase angle between any two voltage and current inputs. All measured quantities are displayed simultaneously on an easy-to-read graphic display. The

18、unique firmware in the POWER MULTIMETER, combined with a built-in microprocessor-based timer, is specifically designed to ease testing and commissioning of protective relay systems, including induction unit pick-up and timing tests. The internal timer responds to a variety of start and stop gates, i

19、ncluding the application of AC or DC voltage, and opening or closing of dry contacts. POWER MULTIMETER is a menu driven instrument equipped with data- retention and TIMED data-logging capabilities. Automatically stores measured data at user defined intervals. Transmit them to a PC on a pre-programme

20、d time interval or save data directly to NOV RAM memory. Other important features include accurate phase angle measurement at very low current levels and the high speed measurement mode. 2.2APPLICATIONS POWER MULTIMETER is an ideal instrument for use in general electrical systems maintenance, in ele

21、ctrical machine repairs, in protective relay testing, or in monitoring power at the electrical service entrance. In the protective relay application area, POWER MULTIMETER is designed to perform fast, accurate checking and testing of protective relay and meter installations, during their commissioni

22、ng and in routine maintenance. Also, combined with a source of voltage and/or current, POWER MULTIMETER becomes an excellent tool for testing and calibrating various types of protective relays. 2.3FEATURES Battery and line operated, with an automatic built-in charger. Rugged, ergonomic and light pla

23、stic enclosure. 4 3 independent voltage and current channels, with a built-in timer. Specifically designed to ease testing and commissioning of protective relay systems.
