SECTION - 3 GENERAL DESCRIPTION 3.1 INTRODUCTION Global Specialities' 2.6KW AUTOSCAN TRUE RMS POWER METER, MODEL 1523 is a state-ofthe-art instrument, ideal for providing all the information about any electrical load connected to the AC Mains. It monitors/scans sequentially all electrical parameters viz., Voltage, Current, Power, VA, & Mains Frequency, thus providing a clear picture of the load. User operation is very simple.
SECTION - 4 OPERATING INSTRUCTION 4.1 IDENTIFICATION OF CONTROLS 1. V - This key is to display the measured mains rms voltage in Volts on LCD. 2. W - This key is to display the power consumed by load, every second, on LCD. 3. F This key is to display the mains frequncy in Hz on LCD. 4. I / RANGE - This key is to display the rms value of measured load current in Amps on LCD. 5. VA - This key is to display the volt-amp of load on LCD and it is updated every second. 6.
1. Mains In - Cord for delivering Mains Power(115V ac) to the instrument. 2. Output - Socket for plugging in the appliance / load to be monitored.There are 2 socets to share the load of 20A equally. 3. Load Switch - Turns ON/OFF outgoing power to the load.Their are 2 switches for 2 output sockets. 4. Fuse - Protective Fuse between mains & load. 5. RS232 Interface Connector connector. 4.
SECTION - 5 REMOTE COMMUNICATION 5.1 INTRODUCTION By using the remote communication facility and the set of remote commands, a PC can completely control the instrument and get information from it. During remote communication, front panel is disabled (except Go Local key) as long as the remote PC doesn’t relinquish control of the instrument or the GO Local key on front panel is pressed. Follow the diagram below for connections. Fig.
5.3 NOTES REGARDING COMMUNICATION i) Definition of signals on ‘RS232’ interface connector on rear panel (5) for remote communication. Pin No. Signal Source Description 2 RXD Remote PC Receive data from Remote PC 3 TXD Instrument Transmit data to Remote PC 5 Gnd — Signal Gnd ii) Communication parameters Bits per second - 9600 Data bits - 8 Parity - None Stop bits - 1 Flow Control - None iii) The commands to the instrument should be in upper case letters only.
SECTION - 6 TESTING & CALIBRATION PROCEDURE 6.1 TITLE : 6.2 REF. DOCUMENTS : 6.3 EQIPMENTS : Testing & Calibration Procedure of Power Meter 1523 1) 2) 3) 4) 5) 5050Power Meter Test Procedure. Power Meter Voltmeter for AC Voltage & Current Meter up to 20A true RMS type. Variac sourcing current up to 20A. Frequency Counter. Load up to 20A AC. 6.4 PROCEDURE : 6.4.1 Testing of PCBs : 1. Check all the PCBs for dry solder, loose contact of components capacitor polarities & ratings etc. 2.
6.4.5 Testing of Manual & Auto Mode : 1. All the parameters can be viewed with the keys on front panel i.e. V, I, W, VA, F. 2. Compare V & I values on display with standard DMM. Also calculate & compareVA & Power for ( for resistive load power should be equal to VA ). 3. Auto scanning of all parameters can be done by pressing Auto scan / GL key. Auto scanning is done at speed of 1 Sec. To come out of auto scan mode, press any other key. 6.4.
