Kepco Power Supply ATE 150-0.7M

Check the PRECISION VOLTMETER (M1) for 'zero' reading and correct, if necessary, with the PREAMP 'A' ZERO control.

Calibration of EXT. CONTROL SOURCE

Set EXT. CONTROL SOURCE to maximum output.

Observe M1 and calibrate the ATE output voltage to the exact maximum rated value by adjusting the Calibrating Control in the EXT. CONTROL SOURCE.

Set EXT. CONTROL SOURCE to zero again.

Re-check the previously calibrated zero point on M1 and correct with the PREAMP 'A' ZERO control if required.

Set the ATE front panel CURRENT CONTROL according to the LOAD requirements, following the procedure given in PAR. 3-28 (2,3,4,5), or use one of the output current programming circuits for remote control of the output current as described in PAR.'s 3-60 or 3-64.

Connect power supply to 115V a-c source or refer to par. 2-4 for other input voltages, if required.

Turn CURRENT CONTROL fully clockwise.

Turn VOLTAGE CONTROL fully counterclockwise.

Turn A-C POWER SWITCH/CIRCUIT BREAKER 'on'.

Is the VOLTAGE VIX indicator energized?

Observe and record the gradual increase of the output voltage as VOLTAGE CONTROL is turned clockwise.

Does the VOLTMETER read full scale?

Refer to Section II, FIG. 2-1 for the location of all internal power supply controls.

Refer to your SN-488 system manual for the location of the system calibration controls.

Set VOLTAGE CONTROL SIGNAL to zero.

Check the PRECISION VOLTMETER (M1) for 'zero' reading.

Correct the M1 reading with the 'E₀ ZERO' control if necessary.

Check the PRECISION VOLTMETER (M1) 'zero' reading and correct, if necessary, with the ATE I₀ ZERO control.

Model SN-488 Output Calibration

Set the Model SN-488 output to 1 volt.

Observe M1 and calibrate the ATE output current to the exact maximum rated output current by means of the SN-488 calibration control.

Set the Model SN-488 output to 'zero' again.

Check the previously calibrated zero point on M1. Correct with the ATE I₀ ZERO control if required.

Ensure all internal controls are located as per Section II, FIG. 2-1

Check the PRECISION VOLTMETER (M1) for 'zero' reading and correct if necessary with the ATE E₀ ZERO control.

Set the MODEL SN-488 input to 10 volts.

Observe M1 and calibrate the ATE output voltage to the exact maximum rated output voltage using the SN-488 calibration control.

Set the MODEL SN-488 output to 'zero' again and check the previously calibrated zero point on M1. Correct with the ATE E₀ ZERO control if required.

Set the ATE front panel CURRENT CONTROL according to your load requirements, following the procedure given in PAR. 3-28 (2,3,4,5), or use one of the output current programming circuits for remote control of the output current as described in PAR.'s 3-60 or 3-64.
