This chapter contains all the information required to control your power supply remotely and discusses in greater detail how each of the commands can be implemented. The material covered is intended for any controller capable of using the GP-IB interface functions mentioned in Interface Functions on page 63. Four major sub-sections are discussed. These are: 1. GP-IB Operation 2. Programming Syntax 3. Initial Conditions 4. Power Supply Commands The GP-IB section briefly describes the GP-IB interf

18 Installation Power Connection Caution: Connection of this supply to an ac power source should only be performed by an electrician or other qualified person. Before connecting the supply to the ac power source, check the label on the rear panel to ensure that the supply is set for the correct ac voltage to be used. If necessary, convert the line voltage to another by following the instructions under “Line Voltage Conversion”. Agilent Models 6010A, 6011A, 6012B and 6015A. To connect input power

Both voltage and current outputs can also be controlled by a voltage source. A voltage of 0 to 5 volts programs the output voltage or current from zero to full scale. Voltage sources of more than 5 volts can be scaled down to the proper range. The following paragraphs discuss in greater detail the methods of remotely programming the output voltage or current using either a resistance or voltage input. Whichever method is used, the wires connecting the programming device must be shielded to reduc

Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument. Agilent Technologies assumes no liability for the customer's failure to comply with these requirements. SAFETY SYMBOLS BEFORE APPLYING POWER. Verify that the product is set to match the available line voltage ! Instruction manual symbol; the product will and that the correct fuse is installed. be marked with this symbol

Push button switches allow the display to alternately show the programmed values of voltage and current or the overvoltage limit. LED indicators show the operating state of the unit (CV, CC, Unregulated and Overvoltage). All connections are made to rear-panel screw-on terminals. Output voltage can be locally or remotely sensed. A six-position MODE switch located on the rear panel is used to change from front panel control to remote voltage or remote resistance control. See section 3 for a descri

n To access hidden keypad, pull up display cover. Select POWER, Source, then: n To set reference, push Abs/Rel and hold Set Ref for 3 seconds (3 buzzer sounds). n To display reference, hold Abs/Rel, so Ref flashes. n To stop / start display update, push Hold. n If a test tone is detected, meter will display Hz. AUTOTEST OPERATION ¦ No user action is required for meter to enter Autotest mode. n Autotest: Push Autotest on source and wait a few seconds. n Can also push Autotest on meter for faster

For proper regulation the load wires should be large enough to limit the voltage drop to no more than 0.5 volts per lead. Table 3-2 lists resistivity for various wire sizes and the maximum lengths that may be used to limit voltage drop to 0.5 volts for various currents. Lengths listed are the sum of the lengths of the (+ ) and ( - ) load wires. Lengths are given in meters and (feet). To determine maximum lengths (in meters or feet) for currents not listed, use the formula: 0.5 x 1000 maximum len

Test Equipment Required The following Table A-1 lists the equipment required to perform the tests and adjustments of this section. You can separately identify the equipment for performance tests, calibration, and troubleshooting in the USE column of the table. Operation Verification Tests The following tests assure that the power supply is performing properly. They do not, however, check all the specified parameters tested in the complete performance test described below. Proceed as follows: A-2

Service Request Enable *SRE 128 Enables the OPER summary bit from the Status Byte register to generate RQS. Operation Condition STAT:OPER:EVEN? When you service the request, read the event register to determine that bit 10 (CC) is set and to clear the register for the next event. 1All bits of the PTR registers bits are set to 1 at power on or in response to STAT:PRES. Adding More Operation Events To add the CV (constant voltage) event to this example, it is only necessary to add the decimal valu
