This device is equipped with a maximum current recording system (maximeter) and the current measurement method is normal and TRUE RMS.\r\n\r\n\r\n## **Features of ammeter 96 Shiva Amwaj**\r\n\r\nIt has a large screen to display current up to 6000A\r\nCurrent measurement and display in two normal and TRUE RMS methods\r\nRecord and display the maximum current\r\nAbility to adjust CT and display it\r\nAbility to precisely adjust CT to calibrate CT\r\nDisplay of overcurrent fault from CTs\r\n4 indicators for announcement\r\nA: Normal flow\r\n TRUE RMS: real current\r\nMAX-A: Maximum current\r\nCT & SETTING: CT setting and its display\r\nDevice setting keys\r\nSELECT: Choose one of the 4 display modes of the device\r\nRESET MAX-A: Zeroing the maximum current recorded when MAX-A is displayed\r\nCT SETTING: CT setting\r\nSave all data during power outage\r\n\r\n\r\n[Click here to view Shiva Amwaj products.](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=19&pfrom=&pto=)\r\n\r\n\r\n\r\n### **Technical specifications of Shiva Amwaj 96 ammeter**\r\nSupply voltage: 180-250V AC/ 50-60 Hz\r\nCurrent measurement accuracy: 0.5%±1 digit\r\nStandard CTs adjustable on the device: 5/(5~6000) CT\r\nCT setting time: from the time of power on for 5 minutes\r\n\r\nEfficiency in:\r\nTemperature -20 to +65 degrees Celsius\r\nhumidity 70%\r\n\r\n\r\n\r\n\r\nConsidering the importance of displaying current, voltage, frequency and other important parameters of the system, a device that can do this permanently and continuously is needed. In practice, in order to be able to display all the recorded values ​​in a device to analyze the power of the system and the power consumption of the desired location, voltage displays must be used.\r\n\r\nThe function of these devices is that it has several terminals to connect the power supply of the device itself, CT wires to measure the current of the phases and connect all three phases to measure the voltage. In fact, by connecting the connections mentioned above, this device will be able to display all the desired items.\r\n\r\n\r\n\r\nOf course, the displays are different in terms of features. Some displays are only capable of measuring three-phase and single-phase voltages, as well as displaying three-phase tolerant current consumption. In addition to measuring the average current and True Rms of three phases and three-phase and single-phase voltages, some monitors are capable of measuring frequency. Some of the devices are also able to be networked. Then we have to choose the desired device according to our needs.\r\n\r\n**Things to know when buying screens are:**\r\n\r\n1- Display power supply voltage\r\n\r\n2- Accuracy of current measurement\r\n\r\n3- Ability to measure True Rms current\r\n\r\n4- The number of indicators\r\n\r\n5- Appearance and type of installation
