Note: LN auxiliary power press the wiring diagram of the instrument housing correct wiring! (AC / DC) switching power supply input interface, auxiliary power multi-function the electricity meter pz568e have universal, if not make a special statement, provided 220V (AC / DC) or 110V (AC / DC) power supply interface standard products, instruments limit the work of the power supply voltage for AC / DC :80-270V, please ensure that the power is applied to the products above to prevent damage to the product. A. AC power 1A fuse is installed in the line of fire on one side is recommended. B. For areas of poor power quality, it is recommended to prevent lightning strikes, as well as a rapid burst suppressor surge suppressors installed in the power supply circuit. Input signal products collected separately calculated for each measurement channel, use exactly the same symmetry, with a variety of wiring, applicable to different forms load. Description: A. Rated input voltage (100V or 400V) voltage input: Input voltage should not be higher than the product, otherwise it should consider the use of the PT, voltage inputs shall be installed 1A fuse. B. Current input: standard rated input current of 5A, greater than 5A should use an external CT. If the use of CT is connected to other instrumentation, wiring tandem, remove the current input connection, be sure to disconnect the CT primary circuit or shorted secondary circuit. Terminal block is recommended, not directly connected to the CT, to facilitate disassembly. C. To ensure that the input voltage, the current corresponding to the phase sequence, in the same direction; otherwise there will be a numeric and symbolic error! ! (Power and Energy) D. The instrument input network configuration is determined according to the number of CT system, three-phase three-wire, two components, in the case of two CT; case 3 CT, three-phase four-wire three components. Enter the network settings NET instrumentation wiring, instrumentation programming should be consistent with the measured load wiring, or will lead to incorrect voltage or power meter measurements. Wherein the three-phase three-wire, a voltage measurement and display of line voltage; while in the three-phase four-wire, the voltage measurement for the phase voltages. Programming and use eight measurements show that PZ568E Multifunction Power Meter can measure the power grid parameters: Ua, Ub, Uc (phase voltage); Uab, Ubc Uea (line voltage) Ia, Ib, Ic (current); Pa Pb, Pc, Ps (per phase active power and total active); Qa, Qb, Qc Qs (reactive power per phase and total reactive power); PFs (total power factor); Ss (total apparent power ); FR (frequency) and active (reactive) power, electricity measurement parameters save all the instrument internal power table, the data collected by instrument digital communication interface can access. And for different models of the instrument, which displays the contents and methods but may be inconsistent, refer specifically described. Nine, the display mode can be set to the XS1 control word for programmed usually display content, XS1 = 0 automatically cycle through 1 (three-phase voltage), 2 (three-phase current), 3 (active power, reactive power, power factor), 4 (frequency) the 5 (watthour information), 6 (reactive energy information). 10, the programming operation in the programming operation, the instrument provides a set (SET) to enter the three categories (INPT), communications (CONN) enter the setup menu item, using LED display hierarchical menu structure management methods: the first row of the LED display Tier 1, the second row of the menu information; LED display Layer 2 menu 3 rows of LED 3 layer menu information. Keyboard programming operation using the mode of operation of the four buttons: move around key "←", "→", the menu enter or on fallback "MENU" button, select OK "to complete the function operation. MENU: in the case of instrument measurements show, press the keypad to enter the programming mode, the instrument prompts Password: CODE enter the correct password, the instrument is programmed to set the instrument factory password is initially 0001; "MENU" another The role is in the programming process, starting retire. For example, in the programming mode, INPT-I.SCL-5, press the "MENU" instrument displays INPT-I.SCL. "→", "←", and to achieve the switching of the menu items or the increase or decrease of the amount of digital switching movement keys. For example, press "→" under the menu item INPT-TU-0001 will become INPT-TU-0002, press and hold the "→", "←" Hold to achieve fast increase / decrease function. "Select and confirm and return to the last menu. Programming way back to the measurement mode, the instrument will be prompted to "SAVE-YES", select "MENU" to exit without saving, select "save and exit.
