Kepco Power Supply ATE 6-25M

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.

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 the following equipment is available

Set CURRENT CONTROL SIGNAL to zero

Check the PRECISION VOLTMETER (M2) for 'zero' reading and correct if necessary with the power supply 'I₀ ZERO' control

Set CURRENT CONTROL SIGNAL to its maximum value

Observe M2 and calibrate the power supply output current to the exact maximum rated value by adjusting the external control voltage (Channel B, full-scale cal. control)

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

Calibration of EXT. CURRENT CONTROL

Set EXT. CURRENT CONTROL to its maximum resistance.

Observe M1 and calibrate the ATE output current to the exact maximum rated value by adjusting the EXT. I₀ CAL. control.

Set EXT. CURRENT CONTROL to zero ohms again.

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

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

Set the MODEL SN-488 input to 10 volts and observe M1.

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' 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.
