Page 22: Notes On Operation
12 Notes on Operation 12.1 Accuracy and Resolution All three outputs provide good accuracy and resolution and offer remote sensing to ensure precise regulation at the load. See section 17 for accuracy specifications. Output 1 offers greater resolution and accuracy than outputs 2 and 3 and uses 5 digit meters to give 1mV and 0.1mA resolution (as against 10mV and 1mA for outputs 2 and 3). -
Page 23: Series Wiring Of Outputs
12.4 Series Wiring of Outputs If voltages above 70 volts are required, this can be achieved by wiring two or more outputs in series. For example, outputs 1, 2 and 3 could be series connected to provide up to 140V. Voltages up to 115V could be achieved by connecting all three outputs in series and selecting voltage tracking so that full voltage adjustments can be made using one output control. -

Page 26: Gpib Interface
The LAN interface is designed to meet LXI (Lan eXtensions for Instrumentation) version 1.4 LXI Core 2011. Remote control using the LAN interface is possible using the TCP/IP Sockets protocol. The instrument also contains a basic Web server which provides information on the unit and allows it to be configured from a web browser. -
Page 27: Usb Interface And Device Driver Installation
13.2.3 USB Interface and Device Driver Installation The instrument firmware can be updated in the field through the USB port. This does not need the driver described here. It requires a PC software utility provided by the manufacturer, and uses a HID driver that will already be installed on the PC. If that is the only USB functionality required, download the package containing the firmware update together with the PC utility from the manufacturer, and follow the instructions included. -
Page 28: Lan Ip Address And Hostname
Since it is possible to misconfigure the LAN interface, making it impossible to communicate with the instrument over LAN, a LAN Configuration Initialise (LCI) mechanism is provided via a push switch (marked LAN RESET) accessible through a small hole in the rear panel. This restores the default configuration with DHCP enabled, so the unit will then follow the sequence described in the previous paragraph. -
