Page 19: Mains Fuses
[Chapter 2] Lever the hinged flap open with a screwdriver and lift out the voltage selector roller block. Refit the block with the chosen voltage value facing outwards. Check that the fuses fitted are of the correct value (Section 4.2 below) and, if necessary, change them.
Page 20: Connection Procedure
[Chapter 2] CONNECTION PROCEDURE Before connecting the supply, ensure that the mains voltage selector on the rear panel is correctly set (Section 4.1), and that the fuses fitted in the mains input unit are correctly rated (Section 4.2). Ensure that the power on/off switch is ‘off’. This switch is located next to the mains input unit on the rear panel.
Page 33 [Chapter 3] NORMAL MODE OPERATIONS POWER-UP MESSAGES “POWER RESTORED,” indicates the 1253 unit has correctly remembered all existing menu settings, History File and Learnt Programs, after a mains supply interruption. “RESET” indicates the 1253 has returned all menu settings to the default state, but left the History File and Learnt Programs as they were.
Page 51: Menu Summary
[Chapter 4] MENU SUMMARY The following tables summarise the1253 menus and action key operations. Notes: { } denote choice via repeated presses of the front panel keys, e.g. {BIAS} is obtained by pressing the GENERATOR Set Up key three times. ( ) denote that a numerical entry is required, e.g.

Page 56 [Chapter 5] GENERATOR The GENERATOR menu sets up all steady-state Generator parameters. {AMPL} AMPLitude. This is the rms amplitude of the ac component of the Generator output, in the range 0V to 10.23Vrms* with a resolution of 10mV. {FREQ} FREQuency. The frequency can be set in the range ImHz to 20kHz with a maximum resolution of l in 4000.

Page 70: Learn Program
[Chapter 5] PAUSE/CONTINUE Inserts a pause when learning or editing programs. If a pre-programmed pause is reached during the execution of a program, the LED will flash on and off. Press the key to continue. LEARN PROGRAM Five options are available. Each option requires the entry of a program number. Use the number entry mode to enter the program number then press ENTER.
Page 80 [Chapter 7] INTRODUCTION An RS423 serial interface is provided on the rear panel. This is for data output to a printer and can be used for printing results, status information or learnt programs. The interface is always ON, allowing printing at anytime. Remote control of the 1253 must be performed via the GPIB.
Page 84 “IEEE Standard Digital Interface for Programmable Instrumentation”. A useful introduction to the theory of the GPIB is given in the Solartron monograph: “Plus Bus –the Solartron GPIB”. GPIB CAPABILITY CODE The GPIB Interface in the 1253 conforms to the following sub-functions within the...
Page 85: Address Switches
[Chapter 8] CONNECTIONS Fig 8.1 GPIB connector and switches on the 1253 rear panel. Connection to the GPIB is made via the 24-way connector on the rear panel of the 1253. See Fig. 8.1. The pin connections conform to the IEEE 489, 1978 Standard. SWITCHES There are eight GPIB switches on the rear panel of the1253, as shown inFig.81.
Page 89: Menu Commands
[Chapter 8] 1253 REMOTE COMMAND CODES The 1253 command codes are based on front panel operations. Each command code consists of a simple ASCII-character string, often qualified by an argument (also in ASCII). Command codes are presented below as menu-commands that set menu parameters;...

Argument mismatch. The wrong type, or number of arguments was used. Argument out of range. Floating point format error.
Page 109 Calibration constants in error; l out of 3. One out of the three internal copies of the calibration constants is corrupted. The 1253 is still usable and measurements are valid, but contact a Solartron service facility. Calibration constants in error; 3 out of 3. All of the three internal copies of the calibration constants are corrupted.

Page 118 [Chapter 11] LEARNT PROGRAM F ACILITIES The 1253 can store a sequence of measurement instructions for execution when required. These Learnt programs are useful where test sequences must be duplicated a number of times, for example in production testing. One instruction is equivalent to a single menu selection. A typical comprehensive program uses less than 50 instructions, each instruction using one memory block.
Page 120 [Chapter 11] PROGRAM clear If number n is wrong, press CLEAR to cancel the operation ENTER Measurement readings, if any To clear all menu settings and programs 1 to 9, use the BREAK {initialise} selection. {learn} To learn a new program, select the {learn} option and, using the number-entry key, input the number of the program to be learnt.
Page 123 [Chapter 11] {copy} Copying is used to make duplicate copies of learnt programs. To copy a given (source) program to another (destination) program select the {copy} option and enter the number of the source program: PROGRAM (n) {copy} ENTER COPY PROG n You now key in the number of the destination program, m.
Page 132: Remote Programming
[Chapter 11] REMOTE PROGRAMMING Remote control programming facilties parallel those available under front panel control. Additional facilities provided are line (instruction) numbering, JUMP instructions, and listing to remote device for external storage, etc. All remote learnt program manipulations can be performed whilst the 1253 is making measurements, but Execute Program commands will not be implemented until the measurement is complete.
Page 133 [Chapter 11] LINE NUMBERING Each learnt instruction can be numbered, for reference purposes or to enable the JP (jump) command to be used. When in ‘program learn’ mode or ‘edit insert’ mode you simply precede each command code by the required number (integer 1 to 98) e.g. 50 SG Line 50 is then the ‘Stop Generator’...
